Sympathoadrenal system
Sympathoadrenal System
The Sympathoadrenal System (pronunciation: sim-pa-tho-ad-ren-al system) is a complex biological system that plays a crucial role in the body's response to stress. It is composed of the Sympathetic Nervous System and the Adrenal Medulla.
Etymology
The term "Sympathoadrenal" is derived from the words "sympathetic" and "adrenal", referring to the two main components of the system.
Function
The Sympathoadrenal System is responsible for the body's fight or flight response. When the body perceives a threat, the Sympathetic Nervous System sends signals to the Adrenal Medulla, which then releases hormones such as Adrenaline and Noradrenaline. These hormones increase heart rate, blood pressure, and blood glucose levels, preparing the body for immediate action.
Components
The Sympathoadrenal System consists of two main components:
- Sympathetic Nervous System: This part of the Autonomic Nervous System is responsible for initiating the body's response to stress. It does this by sending signals to the Adrenal Medulla.
- Adrenal Medulla: This is the inner part of the Adrenal Gland. Upon receiving signals from the Sympathetic Nervous System, it releases hormones that prepare the body for action.
Related Terms
- Adrenaline: Also known as epinephrine, this hormone is released by the Adrenal Medulla in response to stress.
- Noradrenaline: Also known as norepinephrine, this hormone is also released by the Adrenal Medulla and works alongside adrenaline to prepare the body for action.
- Fight or Flight Response: This is the body's physiological reaction to perceived harmful events, attacks, or threats to survival.
