• Dendrites

• Neuromuscular junction

• Cell body

Answer 1

In a nerve cell, the site where the electrical impulse is converted into a chemical signal is known as Neuromuscular junction.

Explanation:

In a nerve cell (neuron):

• An electrical impulse travels along the axon.

• When it reaches the end of the axon, it cannot jump directly to the next cell (which might be another neuron or a muscle cell).

• At this point — called the neuromuscular junction (if the target is a muscle) or synapse (between two neurons) — the electrical signal is converted into a chemical signal.

• This is done by the release of neurotransmitters, which are chemical messengers.
