100
True or False. Resting membrane potential of a neuronal cell is -90mV.
False.
100
This root carries sensory neurons to the CNS.
What is the dorsal root?
100
These main nerve roots are responsible for biceps responding during a stretch reflex?
What is C5, C6?
100
This plexus (include the nerve segments) innervates the muscles of the hind limbs.
What is the lumbo-sacral plexus consisting of nerve segments L2-S2?
100
This part of the ANS is responsible for the fight, flight, fear response.
What is the sympathetic ANS?
200
Causes inhibition at the dendrites of the post-synaptic neuron.
What is the influx of chloride ions?
200
Contains the cell bodies of visceral and somatic sensory neurons.
What is the dorsal root ganglia?
200
Is an example of a complex polysynaptic reflex arc.
What is a withdrawal reflex, or crossed-extensor reflex?
200
The gluteus medius and minimus are innervated by this nerve.
What is the superior gluteal nerve (L4, L5, S1)?
200
Parasympathetic ANS involves only this neurotransmitter.
What is acetylcholine?
300
Part of the nervous system that receives signals that can indicate you are hungry or have a full bladder.
What is the visceral afferent? (autonomic, sensory)
300
This is the order of the three meningeal layers surrounding the CNS from outermost to innermost layer.
What is the dura mater, arachnoid mater, and pia mater.
300
True or False. Withdrawal reflex involves contralateral reflex arc.
False.
300
The axillary nerve innervates these muscles and consists of these two nerve segments. Hint: muscles involved in elevation, and extension.
What is the deltoid muscle and long head of triceps, and C5-C6?
300
The parasympathetic nerve fibers are carried out in these cranial and pelvic nerves.
What is CN III, VII, IX, X, and S2-S4?
400
True or False. Graded potentials are unidirectional.
False.
400
These nerve segments create the cauda equina in the adult spine.
What is L2-S5?
400
This neuron in the stretch reflex is involved in information processing, or sending information to the brain.
What is the motor neuron?
400
The biceps brachii and brachioradialis are innervated by this nerve (include nerve segments)?
What is the musculocutaneous nerve (C5, C6)?
400
The midgut is sympathetically innervated by this nerve.
What is the lesser splanchnic nerve?
500
When the action potential "jumps" from node to node down an axon.
What is saltatory propagation?
500
This ramus sends postganglionic fibers to skeletal muscles and smooth muscles found in the body wall and limbs.
What is the ventral ramus?
500
The peroneal nerve consists of these nerve segments, and is responsible for innervating these types of muscles?
What are L4, L5, and abductors?
500
Celiac ganglia is found in this type of innervation in the ANS.
What is sympathetic innervation?
