Question

explain the structures of a motor nerves cell with the help of a diagram

Answer 1

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. ... Motor neurons carry the electrical impulse to effectors. Effectors are muscles or glands that produce a response.

Structure                    

• Cell body This includes a nucleus which contains the genetic material (chromosomes) of the cell. Surrounding the nucleus are other components that are essential for the functioning of the whole neuron. This is what gives the brain its grey colour (“grey matter”).

• Axon This is a long extension from the cell body and can be up to a meter in length. Usually has two or more branches, called collateral branches.

• Myelin sheath This insulates or protects the axon from external influences that might affect transmission of the nerve impulse. This is what gives the brain it’s white colour (“white matter”).

• Terminal button Sends signals to an adjacent cell (another neuron, a muscle cell etc). This is how information is passed between neurons through electrical impulses.

• Dendrite Receives nerve impulses or signals from adjacent neurons.

This is how information is passed between neurons through electrical impulses.

Answer 2

motor nerves are the nerves which carry messages in the form of responses from the brain or spinal cord to other parts of the body such as muscles and glands the contained only motor fibres
