Sympathetic nervous system

Sympathetic nervous system
The sympathetic and the parasympathetic nervous system are parts of what is commonly called the autonomic nervous system. (Autonomic = can not be controlled by the mind). You can say that these systems work in balance with each other and directly or indirectly affect almost every structure in the body (e.g. heartfrequence, heartcapacity, lumbar function, kidneys, blood vessels, stomach and intestines) The sympathetic nervous system has an active "pushing" function, the parasympathetic has mainly a relaxing function. The sympathetic nervous system is located to the sympathetic chain, which connects to skin, blood vessels and organs in the body cavity. The sympathetic chain is located on both sides of the spine and consists of ganglias. The autonomic nervous system is most important in two situations: emergency situations that cause stress and require us to "fight" or take "flight", and nonemergency situations that allow us to "rest" and "digest".

Love: an emergent property of the mammalian autonomic nervous system. The evolution of the autonomic nervous system provides an organizing principle to interpret the adaptive significance of mammalian affective processes including courting, sexual arousal, copulation, and the establishment of enduring social bonds. According to the Polyvagal Theory (Porges, 1995, 1996, 1997), the well-documented phylogenetic shift in the neural regulation of the autonomic nervous system passes through three stages, each with an associated behavioral strategy. The first stage is characterized by a primitive unmyelinated visceral vagus that fosters digestion and responds to threat by depressing metabolic activity. Behaviorally, the first stage is associated with immobilization behaviors. The second stage is characterized by the sympathetic nervous system that is capable of increasing metabolic output and inhibiting the visceral vagus to foster mobilization behaviors necessary for 'fight or flight'.

Social Engagement System The ventral vagal system is involved with most aspects of social contact and pleasure. It guides eye contact, hearing, eating, speech, singing, nursing, kissing, smiling, and some would say, direct heart to heart contact. Because of its role in making contact between different people favorable, the ventral-vagal system is a way of achieving personal safety, but it requires a moderate amount of actual safety to develop or stay employed.

Polyvagal Theory CN X. Vagus Nerve. The vagus nerve is the longest of the cranial nerve. Its name is derived from Latin meaning "wandering". Viva Las Vagus Nerve A corny title – but a cool nerve. The 10th of the cranial nerves, it is often called the “Nerve of compassion” because when it’s active, it helps create the “warm-fuzzies” that we feel in our chest when we get a hug or are moved by a chick-flick. The vagus nerve is really a bundle of nerves that originates at the top of the spinal cord and enervates all sorts of organs.

The Polyvagal Theory Psychophysiology, 32 (1995), 301-318. Cambridge University Press. Printed in the USA. Department of Human Development, University of Maryland, College Park, USA Copyright, 1995 Society for Psychophysiological Research Abstract Polyvagal Theory Phylogenetic Subsystems/Stages[edit] The vagus nerve is a primary component of the autonomic nervous system. Polyvagal theory outlines the structure and function of the two distinct branches of the vagus, both of which originate in the medulla.[1] More specifically, each branch is associated with a different adaptive behavioral strategy, both of which are inhibitory in nature via the parasympathetic nervous system (PNS). How to Correct Your Pelvic Alignment – Blog About Pelvic Pain Your pelvis is made up of several bones that are “fused” together. There is a group on the left side and a group on the right side. They come together in the middle and there is cartilage in the very front called joining them together. This is your pubic symphysis and it is located just above your penis or clitoris. Feel it, this bone is hard and easy to find.

Central pattern generator Central pattern generators (CPGs) are biological neural networks that produce rhythmic patterned outputs without sensory feedback.[1][2] CPGs have been shown to produce rhythmic outputs resembling normal "rhythmic motor pattern production" even in isolation from motor and sensory feedback from limbs and other muscle targets.[1][2] To be classified as a rhythmic generator, a CPG requires: 1. "two or more processes that interact such that each process sequentially increases and decreases, and 2. that, as a result of this interaction, the system repeatedly returns to its starting condition.[1] Anatomy and physiology[edit] Localization[edit]

What to Do If You Suffer From Middle-of-the-Night Insomnia  It is a common story. You haven't slept well for three days now. The alarm is set for 7 a.m. You get into bed early, hoping that tonight you'll fall asleep early and stay asleep. Instead, you wake up at 2 a.m., staring at the ceiling, wide awake, frustrated and worrying about how you'll function at work the next day.

Anxious Attachment Page 2 of 2 When Attachment Goes Wrong All this would be well and good if all babies and children were responded to in a healthy way. Sadly, it’s estimated that less than half the population has secure attachment behaviors. What's left is most of us. We either have a tendency to avoid feelings and closeness, or a confusing pattern of craving and mistrusting love — in varying degrees, of course.
