Question	Answer
The central nervous system (CNS) consist of?	brain and spinal cord
In the PNS, what is in the ganglia?	neuron cell bodies
In the PNS, what connects to the spinal cord?	spinal nerves
In the PNS, what connects to the brain?	cranial nerves
In the CNS, the center and tracts that link the BRAIN with the rest of the body are the:	sensory and motor pathways
The spinal cord is a part of the:	Central Nervous System
The identifiable areas of the spinal cord that are based on the regions the serve include:	CERVICAL, THORACIC, LUMBAR, SACRAL
The cervical enlargement of the spinal cord supplies nerves to the:	shoulder girdle and arms
If cerebrospinal fluid was withdrawn during a spinal tap, a needle would be inserted into the:	subarachnoid space
The white matter of the spinal cord contains:	Large amount of myelinated and unmyelinated axons
The area of the spinal cord that surrounds the central canal and is dominated by the cell bodies of neurons and glial cells is the:	white matter
The posterior gray horns of the spinal cord contain:	somatic and visceral sensory nuclei
The delicate connective tissue fibers that surround individual axons of the spinal nerves comprise a layer called the:	endoneurium
The branches of the cervical plexus innervate the muscles of the:	neck and extend into the thoracic cavity to control the diaphram
The brachial plexus innervates the:	shoulder girdle and arm
Divergence is the "neural circuit" that permits:	the broad distribution of a specific input
When sensory information is relayed from one part of the brain to another the pattern is called:	serial processing
The final step involved in a neural reflex is:	a response by the EFFECTOR
The goals of information processing during a neural reflex are the selection of:	an appropiate motor response and the activation of specific motor neurons
In the REFLEX ARC, information processing is performed by the:	motor neuron that controls peripheral effectors
The basic motor patterns of innate reflexes are:	genetically programmed
A professional skier making a rapid, automatic adjustment in body position while racing is an example of:	acquired reflex
When a sensory neuron synapses directly on a motor neuron, which itself serves as the processing center, the reflex is called:	monosynaptic reflex
The sensory receptors in the stretch reflex are:	muscle spindles
When one set of motor neurons is stimulated, those controlling antagonistic muscles are inhibited. This is an example of:	contralateral reflex
What basic characteristics do all polysynaptic reflexes share?	reciprocal innervation
As descending inhibitory synapses develop	the Babinski response disappears
The highest level of motor control involves a series of interactions that occur:	in centers in the brain that can modulate or build upon a reflexive motor pattern
In the PNS, neuron cells are located in:	ganglia
The terminal portion of the spinal cord is called:	conus medullaris
The supportive fibrous strand of the PIA MATER is the:	filum terminae
The cell bodies of neurons in the gray matter of the spinal cord form groups called:	nuclei
The white matter of the spinal cord is divided into regions called:	columns
The outermost layer of a spinal cord	epineurium
The branch of eachspinal nerve that provides sensory and motor innervation to the skin and muscles of the back	dorsal ramus
The area where each spinal nerve monitors a specific region of the body surface is known as	dermatome
When 2 neuronal pool synapses on the same motor neurons, the process is called	convergence
Automatic motor responses, triggered by specific stimuli	neural reflexes
A specialized cell that monitors conditions in the body or the external environment	receptor
Connections that form between neurons during development produce:	innate reflexes
Complex, learned motor patterns	acquired reflexes
Reflexes processed in the brain	cranial reflexes
Reflexes that control activities of the muscular system	somatic reflexes
A motor response that occurs on the side opposite the stimulus	crossed extensor reflex
The withdrawal reflex affecting the muscles of the limb	flexor reflex
Elevated facilitation leading to an enhancement of spinal reflexes	reinforcement
Stroking an infant's foot on the side of the sole produces a fanning of the toes	Babinski reflex
axons	nerve bundles
dorsal roots	sensory information to spinal cord
ventral roots	contains axons of motor neurons
spinal meninges	specialized membranes
white matter	ascending,descending tracts
epineurium	outermost layer of spinal cords
cervical plexus	spinal nerves C1-C5
brachial plexus	spinal nerves C5-T1
reverberation	positive feedback
neural "wiring"	reflex arc
peripheral effector	muscle or gland cells
somatic reflexes	controls the activites of the muscular system
stretch reflex	monosynaptic reflex
tendon reflex	golgi tendon organ
crossed extensor reflex	contralateral response
same-side reflex	ipsilateral response
descending pathways	provides facilitation, inhibition
