Study Notes
Role of the Autonomic Nervous System
- Regulates involuntary bodily functions, including heart rate, digestion, and respiratory rate.
- Maintains homeostasis by controlling the internal organs and glands.
Parts of the Autonomic Nervous System
- Divided into three main components: sympathetic, parasympathetic, and enteric nervous systems.
- The sympathetic and parasympathetic systems work in opposition to regulate bodily functions.
Sympathetic vs. Parasympathetic Nervous System
- Sympathetic Nervous System: Prepares the body for stress or emergency situations; increases heart rate, dilates airways, and inhibits digestion (known as the "fight or flight" response).
- Parasympathetic Nervous System: Restores the body to a state of calm; decreases heart rate, constricts airways, and stimulates digestion (often referred to as the "rest and digest" response).
Systems within the Autonomic Nervous System
- Composed of a network of nerves that connect the central nervous system to various organs.
- Includes both motor pathways that control the function of organs and sensory pathways that relay information from the organs to the brain.
'Fight or Flight' Response
- The sympathetic nervous system is responsible for initiating the 'fight or flight' response.
- Activates physiological changes that prepare the body to either confront or flee from danger.
Cholinergic System Receptors
- Contains acetylcholine receptors known as muscarinic and nicotinic receptors.
- Muscarinic receptors mainly affect parasympathetic functions, while nicotinic receptors are involved in both sympathetic and parasympathetic pathways, particularly at neuromuscular junctions.
