Nervous System Divisions
These two structures make up the central nervous system
What are the brain and spinal cord?
this is another name for the neuron's cell body
What is Soma?
These are the two basic cell categories in nervous tissue
What are neurons and glial cells?
The type of nervous tissue contains many neuron cell bodies and dendrites
What is gray matter?
This is the outer connective tissue covering of an entire peripheral nerve.
what is the epineurium?
This division includes nervous structures outside the brain and spinal cord
What is the peripheral nervous system (PNS)?
This structure receives most incoming signals from other neurons
What is dendrites?
These are the cells that provide the support necessary for neurons to survive?
What are glial cells (glia)?
this is the type of nervous tissue consisting largely of axons.
What is white matter?
This is the connective tissue layer that surrounds a nerve fascicle.
What is the perineurium?
This division controls skeletal muscle movement
What is the somatic nervous system
This is the long neuronal process that carries signals toward a target
What is an Axon
This is the type of glial cell that produces myelin around axons in the PNS.
What is Schwann cell?
this is a lipid-rich material that gives white matter its pale appearance.
This is the connective tissue layer that surrounds individual glial-axon units.
What is the endoneurium?
This division regulates cardiac muscle, smooth muscle, and glands
What is the autonomic nervous system (ANS)?
This is the general name for an extension arising from a neuron's soma
What is process or projection?
These are the three special properties that characterize neurons.
What are excitability, conductivity, and secretion?
This is a collection of neuron cell bodies called that are in the PNS
What is ganglion (plural: Ganglia)?
What is the neurilemma?
These are the three branches of the autonomic/visceral motor system described in the course materials
What is sympathetic, parasympathetic, and enteric?
These are the five key regions involved in neuronal communication
What is dendrites, soma, axon, terminal, and synapse?
The reason that neurons require substantial amounts of ATP
What is they are highel metabolically active, electrical signaling and neurotransmitter secretion require engergy?
These are bundles of axons called in the CNS versus PNS.
What are CNS: tracts and PNS: nerves?
name the layers in order from outermost to innermost: endoneurium, epineurium, perineurium
What is epineurium, perineurium, endoneurium
