The Amazing Nervous System: the Human Nervous System

The video explains the human nervous system, highlighting its two main parts: the central nervous system (CNS) and the peripheral nervous system (PNS). The CNS, consisting of the brain and spinal cord, acts as the control center, while the PNS extends throughout the body, gathering and transmitting information. Nerve cells, including neurons and glial cells, play crucial roles in signal transmission and support. Neurons transmit signals, while glial cells, such as Schwann cells and astrocytes, provide support and enhance signal speed.
