Peripheral nervous system

This tutorial by Nicole from Kenhub covers the peripheral nervous system, a part of the nervous system that connects the central nervous system to the rest of the body. It includes the somatic, autonomic, and enteric nervous systems, each responsible for different functions. The somatic system controls voluntary movements, the autonomic system manages involuntary actions, and the enteric system regulates the gastrointestinal tract. The autonomic system is further divided into sympathetic and parasympathetic systems, which handle the body's fight-or-flight and rest-and-digest responses, respectively.

What is the primary role of the peripheral nervous system?

• To control the heart rate

• To facilitate communication between the central nervous system and the rest of the body

• To regulate blood sugar levels

• To transmit signals within the brain

Which type of movement is primarily controlled by the somatic nervous system?

• Regulation of heart rate

• Digestion

• Involuntary movement of internal organs

• Voluntary movement of skeletal muscles

What does the autonomic nervous system primarily control?

• Voluntary muscle movements

• Involuntary functions of internal organs

• Sensory input to the brain

• Balance and coordination

Which system is responsible for the 'fight or flight' response?

• Somatic nervous system

• Parasympathetic nervous system

• Enteric nervous system

• Sympathetic nervous system

What is the main function of the parasympathetic nervous system?

• To prepare the body for physical activity

• To control voluntary muscle movements

• To increase heart rate

• To slow down the heart rate and increase digestion

Where are the main components of the enteric nervous system located?

• In the walls of the gastrointestinal tract

• In the spinal cord

• In the heart

• In the brain

What is the enteric nervous system also known as?

• The central nervous system

• The spinal cord

• The heart of the body

• The brain in the bowel
