HST-AP Introduction to The Nervous System

The video provides an overview of the nervous system, highlighting its primary function of coordinating body activities. It explains the central nervous system, focusing on the brain's six sections and the spinal cord's role. The peripheral nervous system is also discussed, detailing its somatic and autonomic subdivisions. The video concludes with a recap of the nervous system's complexity and functions.

What is the primary function of the nervous system?

• To circulate blood

• To coordinate body activities

• To digest food

• To produce hormones

Which part of the brain is responsible for reasoning and thought?

• Cerebellum

• Occipital lobe

• Frontal lobe

• Temporal lobe

What is the role of the cerebellum?

• Muscle coordination and balance

• Regulating heart function

• Processing visual information

• Directing sensory impulses

What is the function of afferent spinal nerves?

• Carrying information from the brain to the body

• Carrying information from the body to the brain

• Regulating digestion

• Controlling voluntary movements

Which system is responsible for voluntary muscle movements?

• Autonomic nervous system

• Sympathetic nervous system

• Parasympathetic nervous system

• Somatic nervous system

What does the sympathetic nervous system do in response to danger?

• Regulates sleep

• Calms the body

• Processes sensory information

• Revs up the body for action

How does the parasympathetic nervous system affect the body after a threat is gone?

• Stimulates muscle growth

• Enhances sensory perception

• Increases heart rate

• Brings systems back to normal
