Lecture 5 Neuromuscular Junction Flashcards
1
Q
Neuromuscular Junction
A
Motor end plate Single Axon terminal Many mitochondria Synaptic vesicles with acetylcholine 300,000 per axon terminal
2
Q
Single axon terminal
A
Has many mitochondria - needs lots E Synaptic vesicles with acetylcholine Dense bars Synaptic gutter (trough) Synaptic cleft 20-30nm wide Sarcolemma
3
Q
Dense bars
A
Associated with synaptic vessicles to which they are tethered by short filaments
4
Q
Transmission of an Action Potential
A
40nm vesicles are formed in the Golgi apparatus and are carried by axonal transport to the axon terminus where they are filled with Ach
5
Q
Ach synthesized
A
In the cytosol of the nerve axon terminal
