Study Notes
Anatomy and Physiology Overview
- Anatomy studies body structures; physiology studies functions and relationships of body parts.
- Gross anatomy examines larger structures; microscopic anatomy studies structures visible only with magnification.
Levels of Structural Organization
- Chemical level: atoms and elements.
- Molecular level: chemical building blocks of body structures.
- Cellular level: smallest independently functioning unit of life.
- Tissue level: groups of similar cells with a specific function.
- Organ level: two or more tissues working together.
- Organ system level: group of organs performing major functions.
- Organismal level: the complete living being.
Organ Systems
- Multiple organ systems work together to maintain life. (Specific organ systems were shown visually but not listed explicitly in the text)
Characteristics of Human Life
- Organization: structural levels and compartments.
- Metabolism: sum of all biochemical reactions (anabolic – building up; catabolic – breaking down).
- Responsiveness: ability to detect and respond to changes.
- Movement: changing position or location.
- Development, growth, and reproduction: cell differentiation, increasing size, and producing offspring.
Requirements for Human Life
- Oxygen: essential for energy production.
- Nutrients: water, vitamins, minerals, carbohydrates, lipids, proteins.
- Narrow temperature range: around 37°C.
- Narrow atmospheric pressure range: keeps blood gases dissolved and enables breathing.
Homeostasis
- "Steady state": maintaining a stable internal environment.
- Negative feedback: reverses deviations from the set point. Body temperature regulation is an example.
- Positive feedback: intensifies a change; moves further from the normal range. Childbirth is an example.
Homeostatic Mechanisms
- Receptors (sensors): monitor internal/external conditions, detect stimuli.
- Control center (integration center): receives information, analyzes, and sends commands.
- Effectors: respond to control center commands to restore homeostasis.
Anatomical Position
- Body erect, feet parallel, facing forward, head level, arms at sides, palms forward.
Directional Terms & Anatomical Planes
- Directional terms describe body part locations relative to other parts. (Specific directional terms were shown visually but not listed explicitly in the text)
- Sagittal plane: divides the body into right and left halves (midsagittal divides into equal halves).
- Coronal (frontal) plane: divides the body into anterior and posterior.
- Transverse plane: divides the body horizontally into superior and inferior.
Body Cavities
- Ventral (anterior): thoracic (pleural cavities, mediastinum, pericardial cavity) and abdominopelvic (abdominal and pelvic cavities, peritoneal cavity). Separated by the diaphragm.
- Posterior (dorsal): cranial (contains the brain) and vertebral canal (contains the spinal cord).
Body Cavity Membranes
- Serous membranes: double-layered (visceral and parietal), line cavities and cover organs, secrete serous fluid.
- Pleura: lines lungs.
- Pericardium: surrounds the heart.
- Peritoneum: lines abdominal cavity.
Abdominal Regions and Quadrants
- The abdomen is divided into nine regions and four quadrants for detailed anatomical reference. (visual aids were present but not listed)
