2. The knee is DISTAL to the hip because it is farther away from the point of attachment of the hip joint.
3. The wrist is PROXIMAL to the hand because the wrist is closest to the point of origin of the hand.
4. The mouth is INFERIOR to the nose because it is lower in direction to the nose.
5. The thorax is SUPERIOR to the abdomen because it is located above the abdomen.
6. The thumb is DISTAL to the ring finger because it is far away from the ring finger.

Answer:
Generation of an action potential in the neuron.
Stimulation of Ca2+ entry into the neuron
Release of acetylcholine into the synapse
Depolarization of the muscle fiber membrane
Explanation:
The following events takes place in the vertebrate neuromuscular junction
a) Nerve Action Potential - Action potential reaches the axon terminal
b) Entry of calcium ion - The calcium ion reaches the axon terminal and enter into the presynaptic terminus after which the Synaptic vesicles fuse with the membrane of axon terminal
c) Releasing of Arch Quanta - Acetylcholine is released into synaptic cleft which then binds to the receptor sites on motor end plate
d) The Na+/K+ channels opens and Motor end plate becomes depolarized.
