Divisions of the Nervous System

CNS

PNS

Somatic Nervous System

Autonomic Nervous System

Sympathetic vs. Parasympathetic Nervous Systems Sympathetic=ScaredParasympathetic=Peace

 Endocrine system Another communication system…but slower.

Endocrine System  Glands that produce hormones  Hormones—chemical messengers that circulate through blood

Endocrine System Adrenal Glands  Epinephrine and norepinephrine  Response to stress Pituitary Gland  Growth and master gland
