Exam 2 CHSO 404 ACTUAL UPDATED QUESTIONS AND CORRECT ANSWERS
What are parts of the CNS? brain and spinal cord
What are parts of the PNS? afferent sensory, efferent motor, somatic voluntary, and autonomic involuntary
What are the two neural cells and what are their neurons- functional cells of the nervous system that contain the cell body,
functions? dendrites, and axons
schwann cells- supporting cells in the PNS that produce myelin to facilitate rapid
conduction of an action potential
How do nerve cells communicate? action potentials- ionic changes that allow conduction of info along with length of
the axon
synaptic transmission- process by which a neuron conveys info to another cell
such as a neuron, muscle cell, or gland
neurotransmitter- key to synaptic transmission; chemical signal released from the
presynaptic neuron that interacts with the post synaptic cell
, What are the 5 parts of the cerebral hemisphere? frontal lobe, parietal lobe, temporal lobe, occipital lobe limbic system
(Cerebrum)
What does the frontal lobe control? primary motor cortex for precise movement of hands and feet, phonation
(speech), premotor and motor association cortex for planning of complex learned
movement patterns
What does the parietal lobe do? primary somatosensory cortex and somatosensory association cortex for
perceiving the meaningfulness of integrated sensory inputs
What does the temporal lobe do? primary auditory cortex important for discrimination of sounds entering opposite
ears, memory associated with certain sound patterns, long term memory and
recall
What does the occipital lobe do? primary visual cortex, visual association cortex to interpret meaning of visual
experiences
What does the limbic system do? within cerebrum, governs emotional experiences and controls emotion-related
behavior
What is the diencephalon? What two things compose of superior to the brain stem and is enclosed by the cereal hemisphere (the thalamus
this area? and hypothalamus)
What does the thalamus do? relay station for info to and from the cerebral cortex, relays sensory info to the
sensory cortex, relays critical info regarding motor activities to and from regions
of the motor cortex, allows for crud recognition of pleasant and unpleasant, and
some auditory experiences
What does the hypothalamus do? master gland that controls most homeostatic processes in the body- regulates
water balance, hunger-satiety, water balance, overall metabolism, and body
temperature
also controls autonomic nervous system (involuntary) and regulates pituitary
glands
What 2 things make up the brain stem? What does this contains pons and medulla
part of the area control? regulates basic and essential functions like respiratory control center,
cardiovascular control center, and vasomotor center
also controls swallowing, vomiting, micturition, salivation, pupillary diameter,
consciousness, sleep-wake cycle
