Question 38
Label the parts of a neuron in the figure

Answer 1

(a) Dendrites
(b) Cyton
(c) Axon
(d) Axon terminals

Neurons are nerve cells that originate, process, transmit and receive nerve impulses. The axon (nerve fibre) transmits electrical signals from the cell body. The dendrites are branching fibres that receive electrical signals from other neurons. The cell body, also called the soma or cyton, is the spherical part of the neuron that contains the nucleus. The cell body connects to the dendrites, which bring information to the neuron and the axon, which sends information to other neurons. The axonal terminals are specialized to release the neurotransmitters of the presynaptic cell.
