Nervous system
This division of the nervous system is also known as the involuntary nervous system.
ANS or autonomic nervous system
The term central nervous system refers to the?
brain and spinal cord
True or False: one functional center found within the medulla oblongata is a respiratory center involved in the control of the rate and depth of breathing?
True
All processing at the circuit level going up to the perceptual level must synapse in the ________?
thalamus
It is apart of the diencephalon and functions as a relay center for all sensory information entering the brain (except for smell).
thalamus
The ___________ division of the peripheral nervous system transmits information from the skin to the CNS.
sensory or afferent
An inhibitory postsynaptic potential (IPSP) is associated with ___________?
hyperpolarization
which part of the cerebral cortex is involved in intellect, cognition, recall and personallity?
prefrontal cortex
After axonal injury, regeneration in peripheral nerves is guided by _________?
schwann cells
This is the area that regulates body temperature, food intake, and sleep-wake cycle.
hypothalamus
Clusters of cell bodies called ______ are in the CNS and are called __________ in the PNS.
nuclei and ganglia
Immediately after an action potential has peaked, which of the following channels will open?
voltage-gated potassium channels
Injury to the hypothalamus may result in?
loss in body temperature control, sleep disturbances, dehydration
which receptors respond to stimuli within the body?
interoceptors
This structure regulates coordination and balance
cerebellum
Bundles of axons are called nerves in the _____ and tracts in the ______.
CNS and PNS
Which of the following is an excitatory neurotransmitter secreted by motor neurons innervating skeletal muscle?
acetylcholine or ACH
The process of linking new facts with old facts already stored in the memory bank is called
association
a reflex that causes muscle relaxation and lengthening in response to muscle tension is called a ________?
tendon reflex
The motor area of the cortex include the Primary Motor Cortex, Premotor Cortex, ______ Area, and the Frontal _____ Field
Broca's and Eye
True or False: The CNS is the control center for ALL human activities.
False- Although the CNS is a great control center, it does NOT control everything. The endocrine system monitors some things, and certain processes are managed at the cellular level.
he period after an initial stimulus when a neuron is not sensitive to another stimulus is the ________
absolute refractory period
The area of the cortex that is responsible for sensing a full bladder and the feeling that your lungs will burst when you hold your breath too long is the?
visceral sensory area
Spinal nerves exiting the cord from the level of L4 to S4 from the _________?
sacral plexus
This part of the brain stem houses the reflex centers for respiration and cardiovascular functioning.
medulla oblongata
