Study Notes
Autonomic Nervous System
- The sympathetic nervous system is responsible for the 'fight or flight' response.
- The parasympathetic nervous system is responsible for the 'rest and digest' response.
Neurotransmitters
- Acetylcholine is activated by parasympathetic preganglionic fibers.
- Norepinephrine is released by postganglionic neurons of the sympathetic nervous system.
- Acetylcholine is released by postganglionic neurons of the parasympathetic nervous system.
Parasympathetic Nervous System
- Preganglionic cell bodies are located in the brain stem and sacral region of the spinal cord.
- Primary cell bodies are located in the brain stem and sacral region of the spinal cord.
Sympathetic Nervous System
- The adrenal medulla plays a role in the sympathetic nervous system by releasing epinephrine and norepinephrine into the bloodstream.
- Preganglionic cell bodies are located in the thoracic and lumbar regions of the spinal cord.
- The general function of the prevertebral ganglia is to integrate and modulate sympathetic responses.
Receptors
- Muscarinic receptors are activated by acetylcholine in the autonomic nervous system.
- Nicotinic receptors (nAChR) are activated by acetylcholine in the autonomic nervous system.
Miscellaneous
- A common misconception about the autonomic nervous system is that it is only involved in involuntary functions, but it also plays a role in emotional and cognitive responses.
- The vagus nerve plays a key role in regulating the parasympathetic nervous system and is involved in various functions such as heart rate regulation and digestion.
- The enteric nervous system, often referred to as the 'little brain', is a subdivision of the autonomic nervous system that regulates digestion and gastrointestinal function.
