Neurons
A local change in membrane potential that cannot spread far from the site of stimulation
What is a graded potential?
This molecule is released into the synaptic cleft in a somatic neuromuscular junction
What is acetylcholine?
These are the grooves on the surface of the cerebrum.
What are sulci?
The inability to smell may be due to damage to this nerve.
What is the olfactory nerve (CN I)?
It is formed in part by astrocytes and separates the CNS tissue from the general circulation.
What is a the blood-brain barrier?
This is the period where a membrane cannot respond to another stimulation
What is the absolute refractory period?
When a muscle is stimulated so frequently that the relaxation phase is eliminated and maximum tension is reached
What is complete tetanus?
This portion of the brain contains the cardiovascular centers.
What is the medulla oblongata?
This nerve carries sensory information from structures in the inner ear.
What is the vestibulocochlear nerve (CN VIII)?
A reflex response that occurs on the opposite side of where the stimuli was detected.
What is a contralateral reflex?
This is the process of an action potential traveling across an unmyelinated axon
What is continuous propagation?
Nebulin, troponin, and tropomyosin are associated with this type of myofilament.
What are thin filaments?
These are white matter fibers that connect cerebral cortex regions within the same hemisphere.
This nerve carries sensory information from the retina to the brain.
What is the optic nerve (CN II)?
This cell that is associated with skeletal muscle can differentiate to form new fibers.
What are myosatellite cells?
This type of cell is present in the choroid plexus and produces cerebrospinal fluid.
What are ependymal cells?
Where thin filaments are anchored within a sarcomere
What is the Z line?
This brain regions contains the corpora quadrigemina.
What is the midbrain?
A mixed nerve that splits into 3 divisions.
What is the trigeminal nerve (CN V)?
This is the neurotransmitter released at synapses at the end of parasympathetic postganglionic fibers.
What is acetylcholine?
In an axon terminal that is part of a cholinergic synapse, acetylcholine is stored within these intracellular structures.
What are synaptic vesicles?
In this phase Ca2+ is pumped back into SR, tropomyosin covers up active sites and the number of cross-bridges decreases
What is the relaxation phase?
This structure of the limbic system is responsible for linking emotions with memories.
What is the amygdala (amygdaloid body)?
These 2 cranial nerves carry taste information to the brain.
What are the facial nerve and glossopharyngeal nerves? (CN VII and IX)
The hormone by the hypothalamus that influences water retention by the kidneys.
What is antidiuretic hormone (ADH)?
