  5. Nervous system • Nervous System – the body system responsible for helping your body respond to stimuli and react accordingly

  6. Parts of the nervous system • Brain: Control center • Spinal cord: The spinal cord is a bundle of nerves and carries messages to and from the brain. • Nerves: collection of nerve-cell extensions bundled together with blood vessels and connective tissue. • A neuron is a special cell that moves messages in the form of fast-moving electrical energy. These messages are called impulses.

  7. Endocrine system • Endocrine System – the body system responsible for using glands and hormones to regulate the body • Hormone – a chemical that is made in one organ and travels through the blood to another organ

  8. How do hormones work? • Hormones are produced by endocrine glands or tissues and travel through the bloodstream. • A gland is a group of cells that make special chemicals in your body. • Hormones only affect specific target cells that have a specific receptor to that hormone.

  9. What glands make up the endocrine system? • The pituitary gland secretes hormones that control other glands. • The hypothalamus controls the release of hormones from the pituitary gland. • The pineal gland makes hormones that control sleep, aging, reproduction, and body temperature.

  10. What glands make up the endocrine system? • The thyroid gland controls metabolism. • The parathyroid gland controls calcium in the blood. • Reproductive hormones control reproduction. • The pancreas regulates blood-sugar levels.
