Chapter 7 - Nervous System Flashcards
Autonomic Nervous System
Involuntary part of nervous system
Afferent Neuron
Nerve cells that carry impulses towards the central nervous system
Axon
Carries impulses away from the cell body
Brain Stem
Medulla, pons, and midbrain
Central Nervous System
Brain and spinal cord
Cerebellum
Produces smooth muscle coordinated skeletal muscle activity
Cerebral Hemisphere
How the cerebrum is divided
Cerebrospinal Fluid
Produced by Choroid Process; fills ventricles and surrounds the CNS
Dendrites
Carry electrical cells to the cell body
Depolarization
Loss of a state of polarity
Efferent Neuron
Carry impulses away from the CNS
Ganglion
Group of cell bodies located in the Peripheral Nervous System
Gray Matter
Contains unmyelinated nerve fibers
Interneurons
Completes pathway between afferent and efferent neurons
Meninges
Membranes that cover the brain and spinal cord
