Study Notes
Anatomy and Physiology
- The main focus of anatomy is the study of the structure and organization of living things.
Neurophysiology
- Neurophysiology is the subdiscipline concerned with the physiology of the nervous system.
Homeostasis
- Homeostasis is responsible for maintaining a stable internal environment within a living body, ensuring that conditions such as temperature, pH, and blood sugar levels remain constant.
Pathophysiology
- Pathophysiology studies the changes that occur in the body as a result of disease or injury.
Cell Physiology
- Excitability is related to the ability of a cell to respond to stimuli and generate an electrical impulse.
Negative Feedback
- The primary function of negative feedback in the body is to maintain homeostasis by reversing or counteracting changes that deviate from a set point.
- Negative feedback aims to reduce or eliminate deviations from a set point, thereby maintaining a stable internal environment.
- The effector is the component of a feedback loop responsible for carrying out the final corrective action.
- The integrating (control) center in a feedback loop receives and processes information, making the necessary adjustments to maintain homeostasis.
Positive Feedback
- An example of positive feedback is childbirth, where contractions of the uterus stimulate the release of oxytocin, which in turn increases the strength of contractions.
- If positive feedback goes unchecked in the body, it can lead to unstable and harmful outcomes.
- Positive feedback can produce rapid change with beneficial outcomes in certain scenarios, such as in childbirth or blood clotting.
Receptors
- The role of a receptor in a feedback loop is to detect changes in the body and send signals to the integrating (control) center, triggering a response to maintain homeostasis.
