Study Notes
Sympathetic Nervous System
- Acetylcholine is released by preganglionic sympathetic axons.
- Alpha and beta receptors bind to epinephrine and norepinephrine.
- The sympathetic nervous system increases blood pressure in response to stress.
- Sympathetic neurons cause bronchodilation, which increases airflow to the lungs.
- Norepinephrine causes vasodilation of the blood vessels serving skeletal muscles.
- Norepinephrine is released by postganglionic sympathetic axons.
- The sympathetic nervous system is often referred to as the 'fight or flight' division.
- Alpha and beta receptors bind to epinephrine and norepinephrine.
- Acetylcholine is the primary neurotransmitter released by preganglionic sympathetic axons.
- Sympathetic neurons cause vasodilation of blood vessels serving skeletal muscles.
