Study Notes
Anatomy and Physiology
- Anatomy focuses on the structure of the body, while physiology examines the functions and processes of living organisms.
Homeostasis
- Homeostasis is the maintenance of a relatively constant internal environment within the body.
- It regulates most systems to counteract changes in variables and return to a set point.
- The feedback mechanism can either mitigate changes (negative feedback) or amplify them (positive feedback).
Body Temperature Regulation
- A high temperature triggers sweating, while low temperatures can lead to hypothermia.
- Body temperature regulation is vital to prevent hyperthermia and maintain optimal function.
Anatomical Position
- The anatomical position is characterized by the body standing erect, facing forward, with feet together and palms facing forward.
Anatomical Terminology
- Sagittal Plane: Divides the body into left and right parts.
- Frontal Plane: Divides the body into anterior (front) and posterior (back) sections.
- Transverse Plane: Divides the body into superior (upper) and inferior (lower) parts.
Body Regions and Organs
- Liver: Located in the Right Upper Quadrant (RUQ).
- Spleen: Found in the Left Upper Quadrant (LUQ).
- Urinary Bladder: Positioned in the Right Lower Quadrant (RLQ) and Left Lower Quadrant (LLQ).
- Stomach: Located in the Left Upper Quadrant (LUQ).
- Small Intestine: Primarily found in the LLQ.
- Ovaries: Present in both RLQ and LLQ.
- Large Intestine: Distributed throughout.
- Gallbladder: Located in the RUQ.
- Appendix: Located in the RLQ.
