Study Notes
Anatomy and Physiology
- Anatomy studies the structure of the human body.
- Physiology focuses on the function of the human body.
- Both fields are interconnected, exemplifying the "complementarity of structure and function."
Levels of Organization
- Subatomic particles: Electrons, protons, neutrons.
- Atoms: Basic units like hydrogen and lithium.
- Molecules: Examples include water and glucose.
- Macromolecules: Include proteins and DNA.
- Organelles: Functional structures within cells, such as mitochondria and the nucleus.
- Cells: Basic units of life, e.g., muscle and nerve cells.
- Tissues: Groupings of similar cells, such as epithelial, connective, muscle, and nervous tissues.
- Organs: Structures composed of tissues, like the heart and kidneys.
- Organ Systems: Groups of organs that perform specific functions, e.g., the digestive and respiratory systems.
- Organism: The complete human body.
Characteristics of Life
- Movement: Change in position or motion.
- Responsiveness: Reaction to environmental changes.
- Growth: Increase in body size without shape change.
- Reproduction: Creation of new organisms or cells.
- Respiration: Oxygen intake, carbon dioxide removal, and energy release from food.
- Digestion: Breakdown of food into simpler substances.
- Absorption: Passage of substances into body fluids.
- Circulation: Movement of substances through body fluids.
- Assimilation: Transformation of absorbed substances into different chemical forms.
- Excretion: Removal of metabolic waste.
Maintenance of Life
- Life requires five environmental factors:
- Water: Most abundant, essential for metabolic processes and temperature regulation.
- Food: Provides nutrients and energy.
- Oxygen: Vital for energy release from nutrients, constitutes one-fifth of air.
- Heat: A form of energy that partly controls metabolic rates.
- Pressure: Necessary for breathing and blood circulation, including atmospheric and hydrostatic pressures.
Homeostasis
- Homeostasis is the maintenance of a stable internal environment.
- Involves homeostatic control mechanisms to monitor and correct internal conditions.
- Typically employs negative feedback loops for regulation, such as body temperature and blood glucose levels.
- Positive feedback loops amplify bodily actions, e.g., blood clotting and childbirth.
Organization of the Human Body
- Cavities: Include cranial, vertebral, thoracic, abdominal, and pelvic cavities.
-
Serous membranes:
- Visceral layer: Covers organs.
- Parietal layer: Lines cavities.
Anatomical Terminology
- Anatomical Position: Standing erect, facing forward, arms at sides, palms forward.
-
Terms of Relative Position:
- Superior vs. Inferior
- Anterior vs. Posterior
- Medial vs. Lateral
- Ipsilateral vs. Contralateral
- Proximal vs. Distal
- Superficial vs. Deep
- Internal vs. External
Body Sections and Planes
- Sagittal Plane: Divides body into left and right portions.
- Transverse Plane: Splits body into superior and inferior sections.
- Coronal (Frontal) Plane: Separates body into anterior and posterior sections.
Abdominal Subdivisions
- Right Upper Quadrant (RUQ): Contains organs like the liver.
- Left Upper Quadrant (LUQ): Houses organs like the stomach.
- Right Lower Quadrant (RLQ): Includes parts like the appendix.
- Left Lower Quadrant (LLQ): Contains organs like the sigmoid colon.
Body Regions
- Includes Cephalic, Cervical, Thoracic, and Lumbar regions.
- Specific areas like Acromial (shoulder), Brachial (arm), and Femoral (thigh) are noted among body regions.
