Nervous System Functions and Structures

This video tutorial explores the divisions of the nervous system, including anatomical and functional aspects. It covers the central and peripheral nervous systems, the enteric nervous system, and the autonomic and somatic divisions. The video also explains the roles of the sympathetic and parasympathetic systems, highlighting their functions and neurotransmitters involved.

What structures make up the central nervous system?

• Brain and spinal cord

• Cranial and spinal nerves

• Digestive tract

• Heart and lungs

How many pairs of cranial nerves are there?

• 31

• 12

• 5

• 8

Which nerves are part of the peripheral nervous system?

• Heart and lungs

• Brain and spinal cord

• Digestive tract

• Cranial and spinal nerves

What is the role of the enteric nervous system?

• Management of digestive tract functions

• Coordination of sensory input

• Control of voluntary muscles

• Regulation of heart rate

What are the interstitial cells of Cajal responsible for?

• Sensory perception

• Coordinated contraction in the digestive tract

• Voluntary muscle movement

• Heart rate regulation

Which division of the nervous system is responsible for voluntary control?

• Enteric

• Central

• Somatic

• Autonomic

What is the main function of the autonomic nervous system?

• Control of voluntary muscles

• Regulation of involuntary body functions

• Management of digestive processes

• Coordination of sensory input

Which neurotransmitter is associated with the parasympathetic nervous system?

• Serotonin

• Dopamine

• Acetylcholine

• Noradrenaline

What is the sympathetic nervous system often referred to as?
