The Intricate Roles of the Central Nervous System in Human Responses

The video tutorial explains the nervous system, focusing on the central and peripheral systems. It covers how the CNS processes signals and controls voluntary and involuntary actions. The video also discusses body responses to temperature changes and how the brain forms memories and learns new skills through practice.

What is the primary function of the central nervous system?

• To regulate body temperature

• To process signals and send commands

• To control voluntary movements

• To produce hormones

What protects the brain and spinal cord?

• Skin

• Bones and cerebrospinal fluid

• Muscles

• Blood vessels

Which part of the nervous system is responsible for voluntary movements?

• Central nervous system

• Sympathetic nervous system

• Autonomic nervous system

• Somatic nervous system

Which system regulates involuntary functions like heart rate?

• Somatic nervous system

• Autonomic nervous system

• Peripheral nervous system

• Central nervous system

How does the body respond to unexpected pain?

• By activating the involuntary nervous system

• By activating the voluntary nervous system

• By increasing heart rate

• By decreasing blood pressure

What is the body's natural response to an itch?

• To scratch it

• To ignore it

• To apply pressure

• To cool it down

What happens when the outside temperature rises?

• The body starts shivering

• The CNS sends signals to sweat glands

• The heart rate decreases

• The body stops sweating

How does the body generate heat when shivering?

• By reducing sweat production

• By contracting muscles rapidly

• By slowing down metabolism

• By increasing blood flow

What role do neurons play in learning new skills?

• They create and strengthen connections

• They only function during sleep

• They decrease in number

• They become inactive

What happens to neural connections when a skill is practiced repeatedly?

• They remain unchanged

• They strengthen

• They disappear

• They weaken
