Oct. 6, 2011 -- There was about a 60% increase in the estimated number of concussions and other traumatic brain injuries (TBI) seen among young athletes during the past decade, according to the CDC. In 2001, there were an estimated 153,375 traumatic brain injuries among people from birth to age 19. This number rose to 248,418 in 2009. Many of these injuries occurred among bicyclers, football players, and children in playgrounds.

Basketball and soccer players are also at risk for TBI, according to a new report in the CDC's Morbidity and Mortality Weekly Report. Exactly why we are seeing this uptick is not known, but "I believe this is, at least, in part due to increased awareness," says study researcher Julie Gilchrist, MD.

Spinal cord injury (SCI) is an important contributing factor to morbidity and mortality in the United States. Overview Spinal cord injury may occur following damage to the spinal column. The spinal column comprises 31 bones called vertebrae: 7 cervical vertebrae (neck), 12 thoracic vertebrae (upper and middle back), 5 lumbar vertebrae (lower back), 5 sacral vertebrae (sacrum), and 2 fused coccygeal vertebrae (coccyx). Each vertebra comprises a vertebral body and a vertebral arch, which form an enclosed opening (or vertebral foramen).

The vertebrae are stacked on top of each other, aligning the vertebral foramen and forming the spinal column. The spinal cord, the central bundle of nerves extending from the brain and branching peripherally, is responsible for transmitting signals between the brain and the rest of the body.

Muscle TypesThere are three types of muscle tissue: Visceral, cardiac, and skeletal. Visceral Muscle. Visceral muscle is found inside of organs like the stomach, intestines, and blood vessels. The weakest of all muscle tissues, visceral muscle makes organs contract to move substances through the organ. Because visceral muscle is controlled by the unconscious part of the brain, it is known as involuntary muscle—it cannot be directly controlled by the conscious mind.

Gross Anatomy of a Skeletal MuscleMost skeletal muscles are attached to two bones through tendons. Muscles move by shortening their length, pulling on tendons, and moving bones closer to each other. Names of Skeletal MusclesSkeletal muscles are named based on many different factors, including their location, origin and insertion, number of origins, shape, size, direction, and function. Location.

Finally, the skeleton grows throughout childhood and provides a framework for the rest of the body to grow along with it. Skeletal System Anatomy The skeletal system in an adult body is made up of 206 individual bones. These bones are arranged into two major divisions: the axial skeleton and the appendicular skeleton. The axial skeleton runs along the body’s midline axis and is made up of 80 bones in the following regions: SkullHyoidAuditory ossiclesRibsSternumVertebral column The appendicular skeleton is made up of 126 bones in the folowing regions: Upper limbsLower limbsPelvic girdlePectoral (shoulder) girdle SkullThe skull is composed of 22 bones that are fused together except for the mandible.

The bones of the superior portion of the skull are known as the cranium and protect the brain from damage. Hyoid and Auditory OssiclesThe hyoid is a small, U-shaped bone found just inferior to the mandible. Long. Cosmetic Surgery Resources from ASPS | American Society of Plastic Surgeons.

This animation demonstrates the stages of mitosis in an animal cell. Use the control buttons along the bottom to run the complete animation. Click on any intermediate stage (for example, Anaphase), and see a representative still frame. Interphase: Cells may appear inactive during this stage, but they are quite the opposite. This is the longest period of the complete cell cycle during which DNA replicates, the centrioles divide, and proteins are actively produced. For a complete description of the events during Interphase, read about the Cell Cycle.

Prophase: During this first mitotic stage, the nucleolus fades and chromatin (replicated DNA and associated proteins) condenses into chromosomes. Each replicated chromosome comprises two chromatids, both with the same genetic information. Prometaphase: In this stage the nuclear envelope breaks down so there is no longer a recognizable nucleus. Cancer cells reproduce relatively quickly in culture. ChemTube3D. Health Topics. Periodic Table of Elements and Chemistry.
