STRUCTURE
Each neuron contains a nerve cell body with a nucleus and organelles such as mitochondria, endoplasmic reticulum, and Golgi apparatus. Branching off the nerve cell body are the dendrites, which act like tiny antennae picking up signals from other cells.
FUNCTION
Neurons are nerve cells that originate, process, transmit, and receive nerve impulses. They are connected to other neurons or to cells in muscles, organs, or glands.
LOCATION
They are everywhere in your body. You have nerves in your fingertips and your eyelids. You have nerves going to your digestive system...You have major sensory nerves for seeing (optic nerve) and hearing (auditory nerve) and smelling (olfactory nerve). It goes on and on…
hope this helps you
if it does then please mark as brainliest
have a great day:-)

Heya!!!
STRUCTURE AND FUNCTION
Nerve cells serve an important function in our bodies to relay information as electrical signals from the periphery to the central nervous system. Nerve cells are also called 'neurons' and can be as long as 3 feet. Nerve cells are composed of tiny branches called dendrons which branch into further even smaller extensions called dendrites. They also have a nucleus surrounded by cytoplasm, a cell membrane and an axon. The axon is a long fibre that is coated or insulated in a fatty sheath made out of a substance called myelin. This insulation is what adapts the neuron to carry electrical impulses from one place in the body to another.
Neurons work by responding to a stimulus (a change in the environment) that is detected by receptors. There are three main types of neurons- sensory, relay and motor. Once a stimulus is detected, electrical impulses are first sent along the sensory neuron to the central nervous system (CNS). It is then transferred to a relay neuron (also known as an interneuron) which helps pass the information between the sensory neuron and the CNS. These relay neurons can also then pass the information back to a nerve cell known as a motor neuron. Motor neurons carry the electrical impulse to effectors. Effectors are muscles or glands that produce a response.
An example of this process can be shown by how the eye responds to light. Light is the stimulus, detected by light receptors called rods and cones. The amount of light entering the eye is then controlled by the muscles of the iris (the effectors).
LOCATION
They exist throughout the central nervous system (CNS: including brain and spinal cord) as well as the peripheral nervous system (sensory and motor neurons) which 'starts' but extends 'outward' from the spinal cord to our internal organs, limbs, etc. They are everywhere in your body.
