What is the function of a nerve cell in a multicellular organism

Answer 1

The function of a nerve cell, also known as a neuron, in a multicellular organism is to transmit electrical signals and facilitate communication between different parts of the body. Nerve cells receive information from the environment or other cells through specialized structures called dendrites. They process this information and transmit signals, called action potentials, along their long, cable-like extensions called axons. These action potentials travel at high speeds to connect with other nerve cells or target cells, such as muscle cells or gland cells, through specialized junctions known as synapses. Through these synapses, nerve cells can relay messages between different parts of the body, allowing for coordinated responses to stimuli, movement, and many other functions in the organism.
