In the early B. This papyrus was crucial in understanding how the ancient Egyptians understood the nervous system.

This papyrus looked at different case studies about injuries to different parts of the body, most notably the head. Beginning around B. Hippocrates also theorized that the Nerve physiology was involved in sensation, and that it was where intelligence was derived from.

Hippocrates, as well as most ancient Greeksbelieved that relaxation and a stress free environment was crucial in helping treat neurological disorders.

In Galen theorized that human thought occurred in the brain, as opposed to the heart as Aristotle had theorized. The optic chiasm, which is crucial to the visual system, was discovered around C.

CircaAl-Zahrawiliving in Iberiabegan to write about different surgical treatments for neurological disorders. Inthe first anatomy textbook in Europe, which included a description of the brain, was written by Mondino de Luzzi.

InSt Mary of Bethlehem Hospital later known as Bedlam in Britain was the first hospital used exclusively for the mentally ill. InLeonardo da Vinci continued his study of the human body with a wax cast of the human ventricle system. InNicolo Massa described the effects of different diseases, such as syphilis on the nervous system.

He also noticed that the ventricular cavities were filled with cerebrospinal fluid. Inthe term physiology was used for the first time by a French physician named Jean Fernelto explain bodily function in relation to the brain.

InAndreas Vesalius wrote De humani corporis fabricawhich revolutionized the study of anatomy. In this book, he described the pineal gland and what he believed the function was, and was able to draw the corpus striatum which is made up of the basal ganglia and the internal capsule.

This book was devoted to neurological diseases, and discussed symptoms, as well as ideas from Galen and other Greek, Roman and Arabic authors. It also looked into the anatomy and specific functions of different areas.

InAndreas Vesalius worked on a case of hydrocephalusor fluid filling the brain. In the same year, Bartolomeo Eustachi studied the optic nervemainly focusing on its origin in the brain. InGiulio Cesare Aranzio discovered the hippocampusnaming it such due to its shape resemblance to a sea horse.

Altered mood and impulsive behavior Auditory hallucinations Depression[ edit ] Depression is the most common major mental illness and is characterized by both emotional and physical symptoms.

InRobert Burton published The Anatomy of Melancholywhich looked at the loss of important characters in one's life as leading to depression. He mistakenly believed that it was the "soul" of the brain, and believed it was where thoughts formed. InJohann Jakob Wepfer studied a patient in which he believed that a broken blood vessel had caused apoplexyor a stroke.Learn nerve physiology with free interactive flashcards.

The human nervous system consists of billions of nerve cells (or neurons)plus supporting (neuroglial) cells. Neurons are able to respond to stimuli (such as touch, sound, light, and so on), conduct impulses, and communicate with each other (and with other types of cells like muscle cells). A nerve is an enclosed, cable-like bundle of axons (nerve fibers, the long and slender projections of neurons) in the peripheral nervous system. A nerve provides a common pathway for the electrochemical nerve impulses that are transmitted along each of the axons to peripheral monstermanfilm.com: D a) a motor nerve and a myofibril from a neuromuscular junction where gap (called synapse) occurs between the two structures. at the end of motor nerve‚neurotransmitter (i.e.
