The Amazing Nervous System: the Peripheral Nervous System

The video tutorial explains the peripheral nervous system, which includes neurons and sensory organs outside the central nervous system. It details how these neurons connect to the brain and spinal cord, forming cranial and spinal nerves. The peripheral nervous system is divided into the somatic and autonomic nervous systems. The autonomic system controls involuntary functions like heartbeat and digestion, while the somatic system is mostly under voluntary control, as demonstrated by snapping fingers. The sympathetic nervous system connects the central nervous system to muscles and organs.

What is the primary role of the peripheral nervous system?

• To regulate the body's temperature

• To process thoughts and emotions

• To control voluntary muscle movements

• To connect sensory organs and neurons outside the central nervous system

Which nerves are connected to the spinal cord?

• Cranial nerves

• Spinal nerves

• Autonomic nerves

• Somatic nerves

What are the two main parts of the peripheral nervous system?

• Somatic and autonomic nervous systems

• Central and peripheral nervous systems

• Motor and sensory nervous systems

Which system controls involuntary functions like heartbeat and digestion?
