ANATOMY

Detailed explanation-1: -These are the nervous system and the endocrine (hormone) system. These systems regulate body processes through chemical and electrical signals that pass between cells.

Detailed explanation-2: -The nervous system uses tiny cells called neurons (NEW-ronz) to send messages back and forth from the brain, through the spinal cord, to the nerves throughout the body. Billions of neurons work together to create a communication network.

Detailed explanation-3: -Your endocrine system works closely with your brain and central nervous system to control the creation of specific hormones and enzymes. Your digestive and excretory systems work with the nervous system in both conscious and unconscious ways.

Detailed explanation-4: -The nervous system is the major controlling, regulatory, and communicating system in the body. It is the center of all mental activity including thought, learning, and memory. Together with the endocrine system, the nervous system is responsible for regulating and maintaining homeostasis.

Detailed explanation-5: -The endocrine and nervous systems communicate with each other through the hypothalamus, which controls basic drives such as hunger and thirst. The hypothalamus also regulates the pituitary gland, which governs the release of hormones by the body’s other glands.
