Carries nerve impulses to the cell body

Cell body

Neurilemma

Repairs damaged nerve fibres

Cell Body

Processes impulses received & begins nerve transmission. It contains cytoplasm, organelles & nucleus.

Axon

Carries nerve impulses away from the cell body

Cell body

Motor End Plate

Point at which, the nerve impulses reaches a muscle causing contraction. Stimulates the effector which could be a muscle, gland or another neuron.
