Study Notes
Homeostasis
- Refers to the body's ability to maintain a stable internal environment.
- Achieves stability in response to external changes.
Skin Feedback Loop
- Receptor: Located in the skin and muscles, it detects changes in temperature.
- Control Centre: The brain processes information received from the receptors.
- Effector: Includes the erector muscle, sweat glands, and capillaries, which act to restore balance.
- Variable: Represents the conditions that can change, such as hot or cold.
Components of Feedback Loops
- Receptor: Responsible for detecting changes, such as temperature fluctuations.
- Control Centre: Receives information from receptors and sends instructions to effectors.
- Effector: Reacts to signals from the control centre to help return the body to homeostasis.
- Stimulus: The initial change that prompts a response within the body.
Internal Conditions
- Body maintains consistent levels of temperature, glucose, salt, and water.
Diabetes Feedback Loops
-
Low Blood Sugar Variable: Can be caused by skipping meals or excessive exercise.
- Receptor: The pancreas identifies low blood sugar levels.
- Control Centre: The pancreas secretes glucagon hormone, which acts on liver cells.
- Effector: The liver converts glucagon to glucose, releasing it into the bloodstream.
-
High Blood Sugar Variable: Typically results from consuming a meal.
- Receptor: Again, the pancreas detects elevated sugar levels.
- Control Centre: The pancreas releases insulin to manage blood sugar.
- Effector: Insulin facilitates sugar uptake by the liver, converting it into glycogen, thus normalizing blood sugar levels.
