Nerves and Synapses

What is the main function of the nervous system?

• To regulate body temperature

• To digest food

• To produce hormones

• To send, receive, and process nerve impulses throughout the body.

Which part of the nervous system is responsible for transmitting signals from the brain to the rest of the body?

• Spinal cord

• Left pinky toe

• Liver

• Stomach

What are neurotransmitters?

• Hormones that regulate blood sugar levels

• Enzymes that break down food in the stomach

• Proteins that provide structure to the cell membrane

• Chemical messengers that transmit signals across the synapse from one neuron to another

What is the role of neurons in synapses?

How do neurons communicate with each other at synapses?

• Through electrical signals

• Via direct physical contact

• Release and reception of neurotransmitters

• By exchanging hormones

What are the two main divisions of the nervous system?

• Sensory nervous system and motor nervous system

• Brain nervous system and spinal nervous system

• Upper nervous system and lower nervous system

• Central nervous system and peripheral nervous system

What is the function of the central nervous system?

• Regulating body temperature

• Digesting food

• Producing hormones

• Processing and transmitting information throughout the body

What is the role of the peripheral nervous system?

• To process information in the brain

• To transmit signals from the central nervous system to the rest of the body

• To produce hormones

• To digest food

What is the function of neurotransmitters in the nervous system?

• To provide structure to the cell membrane

• To regulate blood sugar levels

• To transmit signals across the synapse from one neuron to another

• To break down food in the stomach
