• The Emotional Brain Structures lying deep within

the cerebral hemispheres.

Coordinates behaviors needed to satisfy motivational and emotional urges arising in the hypothalamus.

Also involved in memory

• Set of glands that regulate the flow or hormones into the bloodstream

• Relatively slow communication system• Interconnected with the nervous system• Pituitary, thyroid, parathyroid, adrenal glands, pancreas, ovaries, testes

Pituitary • Regulates growth• Controls thyroid, ovaries or testes,

pancreas, and adrenal cortex• Regulates water and salt

metabolism• The “master gland”

•Endocrine

Thyroid Controls the metabolic rate

Adrenal Cortex• Regulates

carbohydrate and salt metabolism

• Controls inflammatory response

•Endocrine

Adrenal Medulla• Prepares the body

for action• Secretes stress

hormones

•Endocrine

Pancreas• Controls levels of

insulin and glucagon

• Regulates sugar metabolism
