Anatomical terms of motion

Anatomical terms of motion
In general, motion is classified according to the anatomical plane it occurs in. Flexion and extension are examples of angular motions, in which two axes of a joint are brought closer together or moved further apart. Rotational motion may occur at other joints, for example the shoulder, and are described as internal or external. Classification[edit] Motions are classified after the anatomical planes they occur in, although movement is more often than not a combination of different motions occurring simultaneously in several planes. Gliding motions occur between flat surfaces, such as in the intervertebral discs or between the carpal and metacarpal bones of the hand.Angular motions occur over synovial joints and causes them to either increase or decrease angles between bones.Rotational motions move a structure in a rotational motion along a longitudinal axis, such as turning the head to look to either side. Apart from this motions can also be divided into: Abnormal motion[edit] Other[edit] Related:  Human BodyPhysiology & Geneticsamarsh24

Anatomical terms of location Standard anatomical terms of location deal unambiguously with the anatomy of animals, including humans. Furthermore, the terms are not language-specific, so with little or no translation, they can be understood by all zoologists. While these terms are standardized within specific fields of biology, there are unavoidable, sometimes dramatic, differences between some disciplines. For example, differences in terminology remain a problem that, to some extent, still separates the terminology of human anatomy from that used in the study of various other zoological categories. Introduction[edit] Unique anatomical terminology is used to describe humans and other animals. The vertebrates and Craniata share a substantial heritage and common structure, so many of the same terms are used to describe location. For humans, one type of vertebrate, anatomical terms may differ from other forms of vertebrates. Standard anatomical position[edit] A jellyfish of the Chrysaora species. Combined terms[edit] Bone

3000 Years Of Women’s Beauty Standards In A 3 Minute Video Beauty is indeed in the eye of the beholder, but our idea of beauty over the past few decades has most definitely been programmed into us. Our youth are growing up with mass amounts of marketing around them, as they watch television and participate in life, they are constantly bombarded with a picture of “what is beautiful.” It’s a shame how our children grow up striving to achieve that particular look, and how they can be made to feel “ugly” if they do not fit the accepted model of what our corporations have defined as beautiful. As a result, our youth are not addressing their feelings and emotions, always being taught to look outside of themselves instead of within themselves for the answer. “If tomorrow, women woke up and decided they really liked their bodies, just think about how many industries would go out of business.” – Unknown It’s quite ridiculous when you think about it, because the programmed idea of beauty isn’t even real.

Newfound 'organ' had been missed by standard method for visualizing anatomy -- ScienceDaily Researchers have identified a previously unknown feature of human anatomy with implications for the function of all organs, most tissues and the mechanisms of most major diseases. Published March 27 in Scientific Reports, a new study co-led by an NYU School of Medicine pathologist reveals that layers of the body long thought to be dense, connective tissues -- below the skin's surface, lining the digestive tract, lungs and urinary systems, and surrounding arteries, veins, and the fascia between muscles -- are instead interconnected, fluid-filled compartments. This series of spaces, supported by a meshwork of strong (collagen) and flexible (elastin) connective tissue proteins, may act like shock absorbers that keep tissues from tearing as organs, muscles, and vessels squeeze, pump, and pulse as part of daily function. Importantly, the finding that this layer is a highway of moving fluid may explain why cancer that invades it becomes much more likely to spread. A New Bodily Space

Anatomy Anatomy is the branch of biology concerned with the study of the structure of animals and their parts; it is also referred to as zootomy to separate it from human anatomy. In some of its facets, anatomy is related to embryology and comparative anatomy, which itself is closely related to evolutionary biology and phylogeny.[1] Human anatomy is one of the basic essential sciences of medicine. Definition[edit] Human compared to elephant frame Anatomical chart by Vesalius, Epitome, 1543 The discipline of anatomy can be subdivided into a number of branches including gross or macroscopic anatomy and microscopic anatomy.[4] Gross anatomy is the study of structures large enough to be seen with the naked eye, and also includes superficial anatomy or surface anatomy, the study by sight of the external body features. The term "anatomy" is commonly taken to refer to human anatomy. Animal tissues[edit] A diagram of an animal cell Unlike plant cells, animal cells have neither a cell wall nor chloroplasts.

THE JOINT-BY-JOINT APPROACH Michael Boyle Excerpted with permission from Advances in Functional Training: Training Techniques for Coaches, Personal Trainers and Athletes If you are not yet familiar with the joint-by-joint theory, be prepared to take a quantum leap in thought process. My good friend, physical therapist Gray Cook has a gift for simplifying complex topics. In a conversation about the effect of training on the body, Gray produced one of the most lucid ideas I have ever heard. We were discussing the findings of his Functional Movement Screen (FMS), the needs of the different joints of the body and how the function of the joints relate to training. His analysis of the body is a straightforward one. This joint-by-joint idea has really taken on a life of its own, one I certainly didn’t envision. The table in the next column looks at the body on a joint-by-joint basis from the bottom up. The first thing you should notice is the joints alternate between mobility and stability. Joint — Primary Need

Nerve Structures of the Spine Nerves control the body’s functions including the vital organs, sensation, and movement. The nervous system receives information and initiates an appropriate response. It is affected by internal and external factors (ie, stimulus). Nerves follow tracts and cross over junctions called synapses. Watch our video explaining spinal anatomy—it'll give you the big picture of how the nerves and vertebrae fit together in your spine. Central Nervous System (CNS) The Central Nervous System is composed of the brain and spinal cord. Peripheral Nervous System (PNS) The CNS extends to the Peripheral Nervous System, a system of nerves that branch beyond the spinal cord, brain, and brainstem. The PNS includes the Somatic Nervous System (SNS) and the Autonomic Nervous System (ANS). The ANS is further divided into the Sympathetic Nervous System and the Parasympathetic Nervous System. Just below the last thoracic (T12) and first lumbar (L1) vertebra the spinal cord ends at the Conus Medullaris.

100 Very Cool Facts About The Human Body The Brain The human brain is the most complex and least understood part of the human anatomy. There may be a lot we don’t know, but here are a few interesting facts that we’ve got covered. Nerve impulses to and from the brain travel as fast as 170 miles per hour. Ever wonder how you can react so fast to things around you or why that stubbed toe hurts right away? It’s due to the super-speedy movement of nerve impulses from your brain to the rest of your body and vice versa, bringing reactions at the speed of a high powered luxury sports car.The brain operates on the same amount of power as 10-watt light bulb. Hair and Nails While they’re not a living part of your body, most people spend a good amount of time caring for their hair and nails. Facial hair grows faster than any other hair on the body. Internal Organs Though we may not give them much thought unless they’re bothering us, our internal organs are what allow us to go on eating, breathing and walking around. Bodily Functions Senses

Head and neck anatomy Head and neck anatomy focuses on the structures of the head and neck of the human body, including the brain, bones, muscles, blood vessels, nerves, glands, nose, mouth, teeth, tongue, and throat. It is an area frequently studied in depth by surgeons, dentists, dental technicians, and speech language pathologists. Musculoskeletal system[edit] (a) cranium (8 bones: frontal, 2-parietal, occipital, 2-temporal, sphenoid, ethmoid), and (b) facial bones (14 bones: 2-zygomatic, 2-maxillary, 2-palatine, 2-nasal, 2-lacrimal, vomer, 2-inferior conchae, mandible). As the fetus develops, the facial bones usually form into pairs, and then fuse together. In a newborn, the junction of the parietal bones with the frontal and occipital bones, form the anterior (front) and posterior (back) fontanelle, or soft spots. Circulatory system[edit] Blood circulates from the upper systemic loop originating at the aortic arch, and includes: the brachiocephalic artery, left common carotid and left subclavian artery.

What’s the difference between conventional and sumo deadlifts? Welcome to Chris Beardsley's blog! Please subscribe to my RSS feed. Thanks for visiting! The week before last, I discussed a study in which the biomechanics of conventional and sumo deadlifts were compared. At the end of the study, the researchers concluded that sumo deadlifts involved greater knee extension moments and therefore likely involved the quadriceps to a greater extent than conventional deadlifts. They also noted that the sumo deadlifts led to greater ankle moments, which were dorsiflexion moments throughout the lift, while the conventional deadlift maintained plantar-flexion moments throughout the lift. Finally, they noted that while the conventional deadlift did display a slightly greater hip extension moment than the sumo deadlift, this difference was not significant. However, without electromyographic (EMG) analysis of the muscles concerned during the two types of deadlift, the researchers commented that it was not possible to be certain. What did the researchers do?

How To See An Aura: Learn To See The Hunan Aura Auras are an energy field that is present around every living creature and some inanimate objects. The aura is generated by the 7 major chakras and the 114 minor chakras in the human body. What Color Is Your Aura And What Does It Mean? Your thoughts, emotions, actions, and even dietary choices can impact the aura. The aura is something like a shield. Truly, the ability to see an aura isn't a novelty, but a very practical thing to be able to do. Ny studie: Kvinnor med stor rumpa får smartare barn | HÄLSA Grattis Kim Kardashian! Realitystjärnan vars rumpa blivit känd över hela världen lär glädjas åt det nya forskningsresultatet, som alltså visar att kvinnor med mycket fett kring stjärt och lår har större chans att föda intelligenta barn. Det beror, enligt studiens huvudförfattare Will Lassek, på att fettet runt dessa kroppsdelar är rika på omega 3-syran DHA, som är en viktig komponent i människans hjärna. Testa dig själv: Vilken sorts förälder är du Enligt forskarna bakom studien fungerar höfter, rumpa och lår som en lagringsbank för det nödvändiga fettet, som sedan når den nyfödda bebisen genom bröstmjölken. – Fettet i de här områdena är en källa för uppbyggnaden av en babys hjärna. Den nya upptäckten skulle kunna förklara varför det är så svårt för kvinnor att tappa fett kring rumpa och lår, trots intensiv träning och bra kost. – Det verkar som att kvinnor har utvecklats för att lagra de här fetterna och hålla kvar dem, tills det kommer ett barn, säger Will Lassek till Daily Mail.

Trunk (anatomy) Trunk or torso is an anatomical term for the central part of the many animal bodies (including that of the human) from which extend the neck and limbs.[1] The trunk includes the thorax and abdomen. The trunk also harbours many of the main groups of muscles in the body, including the: The organs and muscles etc. are innervated by various nerves, mainly originating from thoracic vertebrae segments. For instance, the cutaneous innervation is provided by:
