Answer 1

its axonal end when electrical signals are converted into chemical ones 

Answer 2

Answer:

In neuron, "conversion of electrical signal" to a "chemical signal occurs at axonal end".

Option (b).

Explanation:

The neuron is the cell which will carry the electrical signals. It is a part of the nervous system. They send and also receive the signals from the brain.

Each neuron has three parts namely

• Soma,
• Axon and
• Dendrites.

Every neuron is different in shape and size and they also do not get reproduced. At axon, the electrical signal gets converted to the chemical signals. Neurons are divided broadly into 3 parts namely "sensory neurons, motor neurons, and interneuron".

Neurotransmitters released from the axonal end of the "one neuron and transmit the electrical signal to the dendrite of the next neuron".
