Description

Name each part of the neuron

Explain the function of each part

1. dendrites

Dendrites convert signals into small impulses and transmit them inward into the direction of the cell body

2. cell body

The cell body carries genetic information, maintains the structure, and provides energy to drive activities

3. axon

The axon is also called the nerve fibre, it carries nerve impulses away from the cell body as it is typically connected to other neurons or with muscle or gland cells The myelin sheath forms around nerves, including in the brain and spinal cord. It allows electrical impulses to transmit quickly and efficiently along the nerve cells. It is also made of protein and fatty substances The synapsis binds the homologous chromosomes which causes them to be separated during the first division of mitosis. With half a genome, the cells proceed into another cell division and creates gametes. The axon terminals are specialized to

4. myelin sheath (covering axon)

5. synapsis

6. axon terminals

release the neurotransmitters of the presynaptic cell. Then the terminals release substances into a gap called synaptic cleft...
