Information Processing

What is homeostasis?

• A) A disease that affects the body's ability to function

• B) The process by which the body maintains stable internal conditions despite changes in the environment

• C) A type of medication used to treat infections

• D) The body's response to external temperature changes

How is homeostasis controlled in the body?

• A) Through the nervous system exclusively

• B) By the body's muscular system

• C) Through feedback mechanisms involving a cycle of events

• D) By the body's skeletal system

What form of energy is used by sensory receptors to send information to the brain?

• Chemical energy

• Mechanical energy

• Electrical energy

• Thermal energy

What is the role of neurons in the process of sensing and transmitting information?

• To provide energy for the sensory receptors

• To carry information from sensory receptors to the brain and from the brain to the body

• To act as sensory receptors themselves

• To process the information in the brain

How does the brain communicate with various parts of the body to respond to stimuli?

• Through a group of neurons that carry information from sensory receptors to the brain

• By sending chemical signals through the bloodstream

• By using mechanical movements of the muscles

• Through a group of neurons that carry information from the brain to various parts of the body
