Chapter 6 Flashcards
Nerve cell
Neuron
Transmits impulses toward cell body
Dendrite
Integrates signals from sensory neurons
Interneuron
Conductor of impulses from cell bodies
Axon
Has cell body in dorsal root ganglion
Sensory neuron
Group of myelinated nerve fibers within CNS
Tract
Distal end of axon
Motor end plate
Includes major tracts in CNS
White matter
Large cell body with a long axon
Motor neuron
Contains mostly unmyelinated fibers
Gray matter
Has both dendrites and an axon extending from it
Cell body
Fatty sheath
Myelin
Conducts nerve impulses from neuron
Nerve fiber
Collection of axons located near the intervertebral foramen
Posterior root
Break in myelin sheath
Nodes of ranvier
Gap between neurons
Synapse
Collection of dendrites located near intervertebral foramen
Anterior root
Hormone function and behavior
Hypothalamus
Body sensations where pain is perceived
Thalamus
Automatic control of respiration
Medulla oblongata
Coordination of motor movement
Basal ganglia
Control of muscle coordination, tone, posture
Cerebellum
Center for visual reflexes
Midbrain
