Answer

A neuron is the structural and functional unit of the nervous system. It is also called a nerve cell. A neuron has two main parts: the cyton or cell body, and the axon.

Answer

A neuron has two main parts: the cyton, which is the cell body and contains the nucleus, and the axon, which is a long process that carries impulses away from the cell body.

Answer

Dendrites are cytoplasmic extensions of the cell body of a neuron. They help receive impulses and pass them toward the cell body.

Answer

The length of an axon can vary from a few millimetres to 1 metre. The axon is the long process of a neuron and ends in terminal branches.

Answer

Sensory neurons carry impulses from sense organs to the spinal cord or brain. Motor neurons carry impulses from the brain and spinal cord to muscles and glands. Association neurons transmit impulses f…

Answer

Neurons communicate through synapses, not by direct contact. A synapse is a small junction where the axon terminal of one neuron meets the dendrite of another. The message passes by a neurotransmitter…

Answer

A synapse is a small junction used for communication between two neurons. It helps pass a nerve impulse from one neuron to the next using a neurotransmitter.
