Nerve cells

• Cell body - contains the nucleus, which controls all functions of the cell, it also gives the cell structure.
• Myelin sheath - it protects the axons and helps to speed up nerve transmissions.
• Nodes of Ranvier - it allows the generation of fast electrical impulses along the axon, this rate of conduction is known as saltatory conduction.
• Schwann cells - maintains and regenerates the motor and sensory neurones of the PNS.
• Axon - carries electrical impulses across the nerve.
• Dendrites - receive information from other pre-synaptic neurons or from the environment.
• Axon terminal - allows the neuron to conduct electrical impulses down to another neuron by releasing signals into the synapse.
• What is a nerve cell and its function?

  A type of cell that receives and sends messages from the body to the brain and back to the body
