4. In the Autonomic Nervous System, what organs of the body does this system usually
handles? Why they must be in an autonomous fashion?
Answers
The autonomic nervous system is a component of the peripheral nervous system that regulates involuntary physiologic processes including heart rate, blood pressure, respiration, digestion, and sexual arousal. It contains three anatomically distinct divisions: sympathetic, parasympathetic and enteric.
The Autonomic Nervous system is part of the peripheral nervous system, it handles the regulation of heart rate, blood pressure, digestion, and respiration.
- The peripheral nervous system consists of nearly 100 billion nerve cells.
- The organs that the Autonomic Nervous system handles are glands, blood vessels, internal organs like the heart, bladder, and stomach.
- They are autonomous because they are inside our body and they can manage themself on their function.
- The Autonomous Nervous system regulates internal organs to maintain homeostasis.
- The autonomous nervous system consists of two antagonistic sets of nerves, they are the sympathetic and parasympathetic nervous systems.
- The effectors that respond to autonomic regulation are smooth muscles, cardiac muscles, and glands.
