up the CNS. Its main job is to get the information from the body and send out instructions. The peripheral nervous system is made up of all of the nerves and the wiring. This system sends the messages from the brain to the rest of the body. -The peripheral nervous system consists of the nerves that lie outside the brain and the spinal cord. These nerves carry impulses like sensations and information from the body to the spinal cord and from the spinal cord to the body. Thus‚ the peripheral nervous

These organs mostly consist of Nervous Tissues. http://www.nlm.nih.gov/medlineplus/ency/images/ency/fullsize/19588.jpg Nervous Tissues Nervous tissues are made up of two main types of cells: nerve cells/neurons and neuroglia. The main functions of nervous tissues are to react to stimuli and generate impulses to various organs in the body. http://www.occc.edu/deanderson/dennis-tutorial/dennis-jpeg/Nervous%20Tissue-low%20mag%20D-1%20copy Nerve cells and Neuroglia

systems. Cnidarians have a network of loosely arranged nerve cells throughout their bodies‚ forming a nerve net. Flatworms such as planarians exhibit a rudimentary brain with nerve cords traversing the length of their bodies. Mammals have highly evolved nervous systems. They have large brains which process information and sense organs located near the brain. The human nervous system is made up of nerves‚ the brain‚ and the spinal cord. The nerves themselves do not form one single system‚ but several

Evaluate how the name of a muscle can distinguish its location‚ action‚ shape‚ and function. Select five different muscles to make this distinction. Descriptive terms are used to name skeletal muscles. Some names give the location in the body. The temporalis muscle is attached to the temporal bone in the skull. The brachialis muscle is attached to the humerus bone‚ but brachial refers to the main artery in the arm. Some muscles are named for their origins and insertions‚ like the genioglossus

potassium than sodium. When synaptic activity makes the cell less negative‚ the sodium channels open. If the cell voltage goes past a certain level‚ an action potential is produced. Action potentials‚ changes in the membrane potential that happen when a nerve cell membrane is stimulated (Ritchison)‚ happen within milliseconds. After the voltage has reached the threshold potential‚ more voltage-gated sodium channels open and the voltage of the membrane reaches its most positive value. The voltage-gated sodium

Nerve supply is divided into 2 parts Preauricular (nerves entering in front of the ear) and posterior auricular (nerves entering behind the ear).

posterior tibial nerve. Anatomy: The posterior tibial nerve is a branch of the sciatic nerve and innervates the posterior compartment of the legs. As it continues down the leg‚ it passes posteriorly and inferiorly to the medial malleolus. It ends and branches off into sensory branches that innervate the sole of the foot. The tibial nerve travels through the tarsal tunnel and is covered superiorly by the flexor retinaculum. At this point‚ branches stemming from the tibial nerve innervate the heel

Carpal tunnel syndrome is confirmed by the identification of abnormal median nerve conduction tests across the carpal tunnel. Nerve conduction tests are essential in the confirmation of the diagnosis of suspected cases of CTS. These tests are objective tests that assess the physiological status of the median nerve across the carpal tunnel 5 ; 6. The results of electrodiagnostic
