Answer:
- Each nerve cell has a cell body containing a nucleus, endoplasmic reticulum, ribosomes, Golgi apparatus, mitochondria, and other organelles that are essential to the function of all cells.
- The distinguishing characteristic of nerve cells is their specialization for intercellular communication.
- Neurons have two special properties that enable nerves to carryout their two main functions, these are: 1. Excitability / irritability:
- This means they can be stimulated to produce an impulse (action potential) – a tiny electrical current.
- Nerves are bundles of axons in the peripheral nervous system (PNS) that act as information highways to carry signals between the brain and spinal cord and the rest of the body.
- Each axon is wrapped in a connective tissue sheath called the endoneurium.
