When the synaptic vesicles are electrically stimulated by a nerve impulse, synaptic
vesicles gravitate to the outer membrane of the presynaptic wall and release
acetylcholine into the synaptic cleft. The Ach molecules migrate to the postsynaptic cells
where they attach to the specific receptors. When enough neurotransmitters are
received by the receptors to overcome the firing threshold a CMAP is generated
causing muscle contraction. This describes - The events that occur in the
Neuromuscular Junction
What happens to the neurotransmitters after they have attached themselves to
receptors and generated the muscles to contract? - They are chemically broken down
by enzymes and recycled back to the presynaptic terminals
Maximal stimulation is appropriate for , while supramaximal stimulation (not
over stimulation) is necessary in recordings. - SNC, MNC
Martin Gruber Anastomosis is seen when there is a: - Crossover of median fibers to
ulnar fibers in the forearm
Define Afferent nerves: - From the periphery to the cord
Important muscles innervated by the axillary nerve - the Deltoids
Important muscles in the upper arm that are innervated by the radial nerve - The triceps
Which nerve innervates the posterior thigh, leg muscles, planter foot muscles and skin
of the foot - The tibial nerve
Cell bodies of sensory neurons are housed in - The dorsal root ganglion
Which term means the specific region of skin belonging to a single spinal root - A
Dermatome
The nerve most likely to be injured in fractures of the medial epicondyle is the: - Ulnar
nerve
, After a time when a motor nerve to a muscle is sectioned the muscles atrophy. If you
notice that the thenar muscles are atrophied which nerve is suspected of injury? - The
median nerve
