Study Notes
Homeostasis
- Homeostasis is the maintenance of internal conditions, like temperature, near an ideal set point.
- Key variables affecting homeostasis include volume, chemical content, and temperature.
- Sweating acts as a homeostatic mechanism to regulate body temperature.
- While homeostasis strives for stability, actual measurements may fluctuate slightly around the set point.
Feedback Systems
- Feedback systems consist of four components: Receptor, Control Center, Effector, and Stimulus.
- Receptor monitors controlled conditions and sends input to the Control Center.
- Control Center compares received information to the set point and sends output commands to the Effector.
- Effector produces a response to alter the controlled condition towards the set point.
Types of Feedback
- Negative Feedback System reverses changes in controlled conditions to restore set points (e.g., regulation of blood pressure).
- Positive Feedback System enhances changes in controlled conditions (e.g., oxytocin release during childbirth).
Homeostatic Imbalances
- Homeostatic imbalances can lead to disorders (abnormal structure/function) or diseases (illness with recognizable signs/symptoms).
- Signs are objective changes observable by others, while symptoms are subjective changes reported by the individual.
- Diagnosis involves identifying a condition based on signs and symptoms through health history and tests.
Anatomical Positions
- Anatomical Position: Upright body with head level, eyes forward, feet flat, arms at sides, and palms facing forward.
- Prone Position: Lying face downward.
Directional Terms
- Unilateral: On one side of the body.
- Bilateral: On both sides of the body.
- Ipsilateral: Same side relative to a point of reference.
- Contralateral: Opposite sides of the body.
Body Planes
- Longitudinal Section: Cut along the long axis of an organ.
- Transverse Section: Cut across the long axis at a right angle.
- Oblique Section: Cut across the long axis at any angle other than right.
Body Cavities
- Dorsal Cavity includes the Cranial Cavity (houses the brain) and Spinal Cavity (houses the spinal cord).
- Ventral Cavity is subdivided into:
- Thoracic Cavity: Contains the Pleural Cavities (lungs) and Mediastinum (heart and other structures).
- Abdominopelvic Cavity: Includes Abdominal Cavity (stomach, intestines) and Pelvic Cavity (ovaries, uterus, urinary bladder).
Serous Membranes
- Serous membranes line trunk cavities and cover internal organs, filled with fluid to reduce friction.
