Class 11 peripheral nervous system and visceral nervous system-In the context of anatomy and physiology, Class 11 typically covers the peripheral nervous system (PNS) and the autonomic nervous system (ANS), which includes the visceral nervous system. Here’s a brief overview:
- Peripheral Nervous System (PNS):
- Comprises all the nerves outside the central nervous system (CNS), including sensory and motor nerves.
- Divided into the somatic nervous system (SNS) and the autonomic nervous system (ANS).
- Autonomic Nervous System (ANS):
- Regulates involuntary functions of the body, such as heart rate, digestion, respiratory rate, and pupillary response.
- Consists of two main divisions: the sympathetic nervous system and the parasympathetic nervous system.
- Visceral Nervous System:
- Often used interchangeably with the autonomic nervous system (ANS).
- Controls the internal organs and glands, influencing processes such as digestion, metabolism, and excretion.
These systems work together to maintain homeostasis within the body, regulating various physiological processes without conscious effort.
