Anatomy+of+the+Nerve+Cell

By: Kimanh Nguyen

The nerve cell transport messages from one part of the body to another part of the body through nerve impulses.



It includes:
 * 1) Dendrites
 * 2) Nucleus
 * 3) Cell body, a.k.a. soma
 * 4) Axon
 * 5) Myelin sheath
 * 6) Nodes
 * 7) Axon terminals

v Dendrites v Nucleus v Cell body v Axon v Myelin sheath v Nodes v Axon terminals
 * Ø Receive signals/ conduct signals to the rest of the body
 * Ø Contains the genetic information
 * § Has basic cellular organelles, excluding centrioles
 * Ø Produces proteins for dendrites, axons, and synaptic terminals
 * § Long nerve fiber
 * Ø Transfers signals from the cell body to another nerve cell
 * § A material made of protein and phospholipids that surrounds the axons of certain neurons
 * Ø Protect nerve fiber
 * Ø Insulate the nerve fiber
 * Ø Increase the rate of transmission of nerve impulses
 * § Gaps that occur in the myelin sheath of nerve fibers
 * Ø Allow nutrients/waste products to enter/leave the neuron
 * Ø Allow nerve impulses to move along the neuron
 * Ø Receive the signals from the rest of the neurons
 * Ø sends those signals along the branches across the synapses to the dendrites of another cell
