Document Summary

Discuss the anatomical structures and corresponding functions of: Central nervous system (brain and spinal cord) Make clinical application to commonly seen injuries and ailments. Responds to stimuli through muscular contractions or glandular secretion. Motor or interneurons with lots of dendrites. Communicates with other cells via axon terminals. Nodes of ranvier - unmyelinated sections in between sheathed sections. A-delta: small, slow, lightly myelinated, respond to pain & C: very small, very slow, unmyelinated, respond to pain temp. Outermost layer containing many blood vessels and nerves. Thin, spider-like middle layer of connective tissue. Used to diagnose several nervous system diseases. Causes inflammation of meninges (arachnoid and pia mater) Nervous system lecture 5b - spinal cord and nerves. Distal brain to superior border of 2nd lumbar vertebra. Gray commissure - cross bar of h . Myelinated axons of motor and sensory neurons. Reflex : responses to stimuli designed to maintain normal activity. Longitudinal fissure creates right and left hemispheres.
