Systemic Control Systems
How does the endocrine system differ from the ANS?
A. Nervous System
1. Effects within a few milliseconds
2. Action Potentials required
3. Neurotransmitters may or may not be required
a. Excitation
b. Inhibition
Systemic Control Systems
B. Endocrine System
1. Acts within seconds to hours
2. Endocrine glands
3. Hormones
4. Receptors
C. Neuroendocrine System
1. Nervous system may stimulate or inhibit release of hormones
2. Hormones may promote or inhibit nerve impulses

Endocrine Glands
What constitutes the endocrine system?
A. Endocrine glands = Ductless
B. Endocrine system
1. Pituitary (hypophysis)
2. Thyroid
3. Parathyroid
4. Adrenals (Suprarenals)
