Is produced by the influx of both Na⁺ and Ca⁺⁺

Is produced by the influx of Na⁺ and efflux of Ca⁺⁺

Is called the receptor potential

Is called the EPSP

Is called the IPSP

The highly folded nature of the endplate membrane

The presence of high numbers of transmitter in vesicles

The trough design of the neuromuscular junction

The presence of large numbers of docked and primed vesicles

The presence of diffuse synapses from motor neuron to muscle

exocytosis of the vesicle in the post synaptic terminal

import of neurotransmitter into the vesicle

movement of the vesicle to the active zone

docking to the plasma membrane

endocytosis of the vesicle back into the nerve terminal

D and E

A, B, D and E

B and D

Is facilitated by nicotine at nAChRs and by muscarine at mAChRs

Occurs at the two alpha sub-units of the AChR

Occurs at the binding site on the delta sub-unit of the protein

Is inhibited by muscarine at nAChRs and by nicotine at mAChRs

Occurs at a single site on the AChR

The storage of neurotransmitter in vesicles

A groove within the muscle into which the motoneuron terminal inserts

The speed of electrical current flow from motoneuron terminal to muscle membrane

The loss of the myelin sheath over the terminal

The large number of infoldings of the muscle membrane

Ca⁺⁺ allows vesicles to qucikly accumulate [ACh] and then dock, the highly fodled endplate has a high density of ACh receptors (AChR), each AChR binds ACh for long, and only 10% of AChR need to be bound to get a large enough EPP

Vesicles have high [ACh] and are predocked, the highly fodled endplate has a high density of ACh estersase  (AChE), each AChE is able to qucikly degrade ACh for recycling, and only 10% of AChR need to be bound to get a large enough EPP

Vesicles have high [ACh] and can dock quickly, the highly fodled endplate has a high density of Na+ and K+ channels ready to bind ACh, binding of ACh produces a large EPP

Vesicles have high [ACh] and are predocked, the highly fodled endplate has a high density of ACh receptors (AChR), each AChR binds ACh for long, and only 10% of AChR need to be bound to get a large enough EPP

Vesicles have high [ACh] and are predocked, the highly fodled endplate has a high density of ACh estersase  (AChE), each AChE is able to qucikly degrade ACh for recycling, and Clathrin can quickly recycle ACh vesicles

Motor neurons in the ANS are always myelinated and have large axon diameters

Motor neurons in the ANS are always myelinated and have small axon diameters

Conduction velocity is faster than in motor neurons that innervate skeletal muscle

Motor neurons in the ANS can be myelinated or unmyelinated, both with small axon diameters

Motor neurons in the ANS can be myelinated and unmyelinated and have large axon diameters
