Understanding the Nervous System

The video tutorial explains the nervous system, which coordinates body activities through electrical signals using neurons. It divides into the central nervous system (brain and spinal cord) and the peripheral nervous system (nerves throughout the body). The peripheral system connects the central system to limbs and organs, further divided into the somatic (voluntary muscle control) and autonomic (internal body functions) systems. The autonomic system includes the sympathetic (emergency response) and parasympathetic (resting state) branches. The video concludes with a message promoting kindness.

What is the primary function of the nervous system?

• To digest food

• To produce hormones

• To coordinate body activities

• To circulate blood

Which part of the nervous system includes the brain and spinal cord?

• Central nervous system

• Peripheral nervous system

• Autonomic nervous system

• Somatic nervous system

What is the main role of the peripheral nervous system?

• To control digestion

• To connect the central nervous system to limbs and organs

• To regulate blood pressure

• To produce electrical signals

Which system is responsible for voluntary muscle movements?

• Somatic nervous system

• Central nervous system

• Peripheral nervous system

• Autonomic nervous system

What type of neurons carry information from the brain to muscles?

• Sensory neurons

• Motor neurons

• Interneurons

• Relay neurons

Which system contains sensory and motor neurons?

• Peripheral nervous system

• Autonomic nervous system

• Central nervous system

• Somatic nervous system

What is the role of sensory neurons?

• To carry information to the central nervous system

• To regulate internal body functions

• To control voluntary movements

• To connect the brain to the spinal cord

Which system regulates heart rate and digestion?

• Somatic nervous system

• Autonomic nervous system

• Peripheral nervous system

• Central nervous system

What does the sympathetic nervous system do during emergencies?

• Lowers body temperature

• Decreases breathing rate

• Increases blood pressure

• Slows down the heart rate

When does the parasympathetic nervous system become active?

• During digestion

• When the body is at rest

• In emergencies

• During physical activity
