The Nervous System

What is a synapse?

• The junction between two neurons where information is transmitted.

• A type of neurotransmitter released in the brain.

• A structure that protects the brain from injury.

• A type of electrical signal sent through the body.

How does the spinal cord contribute to the nervous system?

• Transmitting messages between brain and body.

• Regulating blood flow in the body.

• Producing hormones for growth.

• Filtering toxins from the bloodstream.

What is the peripheral nervous system?

• The part of the nervous system outside the central nervous system.

• The part of the nervous system that controls voluntary movements.

• The part of the nervous system responsible for processing sensory information.

• The part of the nervous system that regulates involuntary functions.

What is the main function of the nervous system?

• To transmit and process information.

• To produce hormones.

• To digest food.

• To circulate blood.

What is a reflex arc?

• The pathway that a reflex takes, involves sensory neurons, and motor neurons.

• A type of voluntary movement controlled by the brain.

• A process that only involves sensory neurons without motor neurons.

• A reflex action that occurs without any neural pathways.

True or False: The brain is in control when we have a reflex response to stimuli.

• True

• False

• The brain is partially in control

• The spinal cord is in control

Define reflexes.

• An automatic response.

• A learned behavior.

• A conscious decision.

• A voluntary action.

What is the central nervous system composed of?

• The brain and spinal cord.

• The heart and lungs.

• The stomach and intestines.

• The kidneys and bladder.

What role does the brain play in the central nervous system?

• Regulating body temperature and metabolism.

• Processing sensory information and decision making.

• Controlling muscle movement and coordination.

• Producing hormones and enzymes.

What is the function of sensory neurons?

• To carry signals from sensory receptors to the central nervous system.

• To transmit signals from the brain to muscles.

• To process information and generate responses.

• To connect different parts of the nervous system.
