Parts of motor neuron/nerve

Functions of parts of nerve cell

• Nerve fibre or axon transmits impulses
• The myelin sheath protects the axon; it also insulates the axon and speeds up transmission of impulse.
• Nucleus controls cellular activity
• Dendrites or make contacts with other nerve cells or effector
• Nodes of Ranvier are microscopic gaps found within myelinated axons. Their function is to speed up propagation of action potentials along the axon via saltatory conduction
• The cell body preserves the structural integrity of the neuron, houses the genetic material, and supplies energy to drive activities.
