Nervous System Explained In Simple Words

The video explores the nervous system, highlighting its complexity beyond just the brain. It explains the central and peripheral nervous systems, their subdivisions, and functions. The roles of neurons and glial cells are detailed, including their structure and function. Neural circuits, reflexes, and their significance in rapid responses are discussed, emphasizing the nervous system's role in communication and control within the body.

• To calm the body and promote digestion

• To control voluntary muscle movements

What is the function of Schwann cells in the nervous system?

• To form the blood-brain barrier

• To provide insulation to neurons in the PNS

• To act as immune cells in the CNS

• To transmit nerve impulses

Which type of neuron carries signals from the CNS to the periphery?
