Very short term control (milliseconds – seconds)
Control and coordination throughout the body
Relatively short term (seconds to minutes) or long term (days to weeks) control.

4. Nervous System vs. Endocrine System
Share areas of the brain
Thalamus
Receives, analyzes, and sends information from all the senses
Hypothalamus
Regulates hunger, thirst, the sex drive, and other motivated behavior

5. Limbic system 4 main structures: Amygdala Hippocampus
Regions of the limbic cortex

Influences autonomic nervous system (ANS) and endocrine system.
Sense of smell, behavior, learning, long-term memory, emotions, and drives.
Sympathetic
Adrenalin is released from the adrenal gland.

7. Pituitary Gland The hypothalamus is connected to the pituitary gland

Pancreas
Ovaries or Testes
These all produce one or more hormones!
