Study Notes
Subdivisions of Anatomy
- Embryology: Focuses on the first 8 weeks of human development.
- Developmental Biology: Covers all stages of development from conception to adulthood.
- Cell Biology: Examines cell structure and its functions within biological systems.
- Histology: Studies the microscopic structure of tissues.
- Surface Anatomy: Involves visualization and palpation to observe surface markings of the body.
- Gross Anatomy: Studies structures that can be seen without a microscope.
- System Anatomy: Analyzes the structures of specific organ systems.
- Regional Anatomy: Investigates the structure of specific regions of the body.
- Radiographic Anatomy: Utilizes X-ray, CT, or MRI to visualize internal body structures.
- Pathological Anatomy: Examines structural changes that occur due to disease.
Physiology
- Definition: The study of the functions of the human body and its systems.
- Functional Systems: Includes nervous, endocrine, cardiovascular, immunologic, respiratory, and renal systems.
- Exercise Physiology: Investigates how exercise impacts bodily functions.
- Introductory Pathophysiology: Examines changes in body functions due to disease.
Anatomical Position & Directional Terms
- Anatomical Position: Standard posture where the individual stands erect, facing forward, with arms at sides and palms facing forward.
-
Directional Terms: Terms used to describe the position of structures relative to one another. Common terms include:
- Superior: Above or on top of
- Inferior: Below or beneath
- Superficial: Toward the surface
- Deep: Toward the core
Abdominopelvic Regions
- Right Hypochondriac Region: Under the rib cage.
- Epigastric Region: Above the stomach.
- Left Hypochondriac Region: Under the left rib cage.
- Right Lumbar Region: Lower back on the right side.
- Umbilical Region: Centered around the navel.
- Left Lumbar Region: Lower back on the left side.
- Right Inguinal Region: (Right iliac) Groin area on the right.
- Hypogastric Region: Below the stomach (pubic region).
- Left Inguinal Region: (Left iliac) Groin area on the left.
Homeostasis and Feedback Mechanisms
- Homeostasis: Maintenance of stable internal conditions despite external changes.
-
Control Mechanisms: Involve variables, receptors, control centers, and effectors. Example:
-
Body Temperature Regulation:
- Variable: Body temperature
- Receptor: Thermoreceptor
- Control Center: Hypothalamus
- Effector: Sweat glands and blood vessel dilation
-
Body Temperature Regulation:
- Positive Feedback Loops: Enhance or intensify the stimulus, rare in the body. Used in processes like childbirth and blood clotting.
Measurement Systems
-
US Customary vs. Metric System: Comparison of units.
- Length: Inches (US) vs. Meters (Metric)
- Mass: Pounds (US) vs. Grams (Metric)
- Volume: Gallons (US) vs. Liters (Metric)
- Temperature: Fahrenheit (US) vs. Celsius (Metric)
-
Metric System Base Units:
- Meter (m): Length
- Gram (g): Mass
- Liter (L): Volume
- Second (s): Time
- Degree Celsius (°C): Temperature
- Mole (mol): Amount of matter
Contextual Understanding
- Familiarize with both the US customary system and the metric system for accurate measurement and scientific communication, especially in biology and medicine.
