Study Notes
Nervous System Organization
- The Peripheral Nervous System (PNS) includes neurons located outside the brain and spinal cord.
Function of Neurons
- Motor neurons carry signals away from the brain and spinal cord to the peripheral tissues.
Neurotransmitters and Receptors
- Nicotinic and muscarinic receptors are stimulated by acetylcholine.
- Adrenergic receptors are stimulated by norepinephrine and epinephrine.
Central Nervous System
- The Central Nervous System (CNS) is composed of the brain and spinal cord.
Autonomic Nervous System Function
- The autonomic nervous system regulates function by interacting with sympathetic and parasympathetic nerves.
