Question

Nerve cells have many short branches called..............
A) Dendrites
B) Neurons
C) Axons
D) Neutrophils

Answer 1

Hint: Nerve cells are the active component of the nervous system. Its main function is to transmit nerve impulses or communicate with the other cells by the help of electric signals. The response to stimuli is due to nerve impulse.

Complete Answer:
To answer this question, we must know about the structure of nerve cells.
The basic unit of the nervous system is the nerve cell or neurons. Nerve cells receive and transmit information from one neuron to another and also to muscle and gland cells. Human nervous system comprises around 1020 neurons.
Anatomy of neurons/nerve cells

The neuron consists of the following parts-
Cell body- It is called the soma. It contains nuclei.
Dendrites-These are tree-like branched structures which arise from the nerve body. The dendrites of one neuron are joined with the axon of another through synapse
Axon- These are the single elongated structures that extend and branch at the end.
Myelin sheath cells- These are found wrapped around the axons.

The neurotransmitters are secreted at the synapse to help in transmission of impulses.
 Neutrophils- These are the granulated WBC. The main function of neutrophil is phagocytosis.

The correct answer is (A). Nerve cells have many short branches called Dendrites.

Note:Dendrites may branch significantly depending on the type of cell it is associated with. Dendrites receive the electrical impulses from the axon of another nerve. It is then accumulated in the cell body or some before transmission.
