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
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.
