📖 1. Neurons and Glial Cells

★ Must-know

• The nervous system comprises two main cell types: neurons and glial cells.

• Neurons are highly specialized cells and the functional units of the nervous system; humans have about 100 billion neurons.

• Neurons secrete neurotransmitters and neurotrophic factors.

• Neurons have very high metabolic activity and consume large amounts of oxygen, glucose, and ATP.

Further detail

• Neurons are excitable cells, like myocytes and glandular cells.

• Neurons are amitotic cells.
