Study Notes
Autonomic Nervous System (ANS) Overview
- The Autonomic Nervous System (ANS) is mainly activated by centers located in the spinal cord, brain stem, hypothalamus, and portions of the cerebral cortex (limbic cortex).
- The ANS controls involuntary functions of the body, such as blood pressure, gastrointestinal (GIT) motility and secretions, urinary bladder emptying, sweating, and body temperature.
Objectives of Studying ANS
- To understand the functions and regulation of the ANS.
- To appreciate the role of the ANS in maintaining homeostasis.
- To recognize the importance of the ANS in various physiological processes.
Characteristics of ANS
- The ANS has the ability to rapidly change visceral function with varying degrees of rapidity and intensity.
- The ANS is a complex system that regulates involuntary functions of the body.
Neurotransmission in ANS
- Acetylcholine (ACh) and norepinephrine (NE) are involved in neurotransmission within the ANS and its target organs.
- Modulators can alter neurotransmitter synthesis, storage, release, and reuptake, and receptor activation and blockade within the ANS.
Comparison of Parasympathetic and Sympathetic Nervous Systems
- The parasympathetic nervous system promotes relaxation, reduces energy expenditure, and increases digestion.
- The sympathetic nervous system prepares the body for "fight or flight" responses, increasing energy expenditure and reducing digestion.
Topics Covered in the Study of ANS
- Anatomy and physiology of the ANS.
- Functions and regulation of the ANS.
- Neurotransmission and modulation in the ANS.
- Sympathetic and parasympathetic nervous systems.
