• Central and peripheral nervous systems

• Neurons and synapses

• Glands and receptors

What does the spinal cord do?

• Processes sensory information

• Controls breathing

• Transmits signals between the brain and body

• Produces hormones

What is the main function of the autonomic nervous system?

• To control involuntary functions like heartbeat and digestion

• To transmit information to muscles

• To process emotions

• It releases hormones into the blood

• It activates the "fight or flight" response

• It reduces blood flow to muscles

• It increases body temperature

What does the peripheral nervous system do?

• Processes information from the brain

• Controls the body's internal environment

• Connects the central nervous system to the rest of the body

• Controls automatic functions like digestion

What happens if the spinal cord is damaged?

• The heart stops beating

• Sensory and motor functions below the injury may be lost

• Reflex actions become stronger

• Hormones are no longer produced
