Anatomy & Physiology Nervous System Test
Key concepts, Questions and Answers
Abducens (VI) - anscontrols lateral eye movement
Acoustic (VIII) - ansControls Hearing & Balance
Autosomatic Nervous System - anssupplies motor impulses to cardiac muscle, to smooth muscle & to glandular
epithelium
Axon - ansCarries information AWAY from the cell body toward the axon terminal
Axon terminal - ansthe end of the axon that forms a synapse with another neuron
central canal - ansthe hole in the center of the spinal cord
cerebellum - ans2nd largest structure of the brain. Coordinates skeletal muscle movement. Responsible for
learning new motor tasks (i.e. throwing a ball). Located lower back part of brain
Cones - ansActivation of cones causes color vision
Dendrite - ansCarry information TOWARD the cell body
Depolarization - ansInside neuron becomes less negative -50mV due to inward movement of Na
Facial (VII) - ansControls facial expressions & taste
Frontal Lobe - ansportion of brain responsible for thinking, planning, problem solving, judgement, voluntary
, movement
Glossopharyngeal (IX) - ansControls swallowing and voice
gray matter - anscomposed of cell bodies and unmyelinated interneurons
Hypoglossal (XII) - ansControls tongue movement & strength
hypothalamus - ansexerts control over all internal organs, controls body temperature, sleep-wake cycle, H20 &
electrolyte balance, apptite
Interneuron - ansnerve cell that carries impulses from a sensory neuron to a motor neuron
Iris - ansThe colored part of the eye
Level of stimulation for resting membrane - ansAction Potential carries a charge of -70 mV
Level of stimulation for resting potential - ansStimuli threshhold of -55mV
meninges - ansthree layers of protective tissue that cover the brain & spinal cord
Myelin Sheath - ansincreases the volocity of neurons
Name the 3 major plexuses - ansCervical, Brachial and lumbosacral
Neuron - ansThe primary cell of the nervous system
