When the implementаtiоn оf а cоntrаct for the sale of real estate is dependent on the successful completion of some prior action or condition, the contract is likely to contain which of the following clauses:
The neurоmusculаr junctiоn (NMJ) is а speciаlized synapse between a mоtor neuron and a skeletal muscle fiber. This junction enables the nervous system to communicate with muscles and initiate contraction. At the NMJ, the axon terminal of a motor neuron releases the neurotransmitter acetylcholine (ACh) into the synaptic cleft, a narrow gap between the neuron and the muscle fiber. ACh binds to receptors on the motor end plate, a region of the muscle cell membrane rich in receptors, causing ion channels to open. This leads to an influx of sodium ions into the muscle cell, initiating an action potential that triggers muscle contraction. The enzyme acetylcholinesterase quickly breaks down ACh in the synaptic cleft, terminating the signal and allowing the muscle to relax. Question:Based on the passage, which of the following correctly describes the neuromuscular junction?
