BIO163 review for Final Exam
select each nerve that is correctly paired to the spinal plexus of its origin. select all that are correct
*phrenic nerve- cervical plexus *radial nerve- brachial plexus *sciatic nerve- sacral plexus
BLANK is the middle membrane of the meninges
Arachnoid mater
BLANK is the outermost layer of the meninges
Dura mater
regulates visceral activities and involuntary responses
brainstem
the autonomic division is involved in controlling
cardiac muscle, glands, and adipose tissue
the dendrites of a neuron
carry impulses toward the cell body
coordination of posture, balance, and muscle movement
cerebellum
the part of the brain that coordinates voluntary muscle movements is the
cerebellum
autonomic division reflex pathways fundamentally depend on all of the following CNS regions EXCEPT the
cerebrum
largest part, used for reasoning, memory, and voluntary responses
cerebrum
collection of myelinated axons which connect cerebral hemispheres
corpus callosum
the peripheral nervous system (PNS) consists of
cranial nerves, spinal nerves, ganglia, and sensory receptors
contains the thalamus and region below it
diencephalon
the ________ is filled with blood and absorbs the cerebrospinal fluid
dural sinus
multipolar neurons are
either motor neurons or interneurons
________ are involved in the production of cerebrospinal fluid
ependymal cells
a deep groove seen on the surface of brain separating the two cerebral hemispheres
fissure
neuron cell bodies are located in the _______ matter, and myelinated axons are located in the ______ matter
gray, white
ridge or convolution on surface of brain
gyrus
automatic control center and links the brain to endocrine system
hypothalamus
if a neuron is located entirely in the CNS, this neuron is a(n)
interneuron
supports involuntary functions using respiratory cardiac and vasomotor control centers
medulla oblongata
in brainstem has auditory and visual reflex centers
midbrain
in a resting neuron, the plasma membrane is
more permeable to potassium ions than to sodium ions
the ______ increases the speed of action potential transmission
myelin sheath
the areas identifying sensations from skin stimulation are located in the
parietal lobe
which of the following disorders is caused by insufficient production of dopamine in the brain
parkinson disease
helps maintain breathing and connects to cerebellum
pons
the ______ is involved in controlling complex learned activities, such as driving
premotor area
the ________ controls skeletal muscles
premotor area
which of the following lists parts of a reflex arc in the correct sequence?
receptor--> sensory neuron--> CNS--> motor neuron--> effector
_________ form the myelin sheath around axons in PNS
schwann cells
if a neuron's cell body is located in PNS, this neuron is a(n)
sensory neuron
biopolar neurons are
sensory neurons for the sense of hearing, equilibrium, vision, and smell
unipolar neurons are
sensory neurons other than the ones for the senses of hearing, equilibrium, vision, and smell
which one of the following activities is directly controlled by the autonomic division
shivering
a shallow groove seen on the surface of brain
sulcus
relays sensory information to the cerebral cortex
thalamus
the motor division of the nervous system carries action potentials from
the CNS to the effectors
the sensory division of the nervous system carries action potentials from
the sensory receptors to the CNS
a strike on the back of the head will most likely affect which function of the cerebrum
vision
