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.
