    Study Notes

    Anatomy and Physiology

    • Anatomy studies the structure of the body and relationships between its parts.
    • Physiology explores the functions of body parts and the processes within the body.
    • Form and function of biological structures are interrelated.

    Levels of Structural Organization

    • Chemical Level: Composed of atoms and molecules (e.g., C, H, P, O, N, S).
    • Cellular Level: Basic structural and functional units of life.
    • Tissue Level: Groups of cells working together, including epithelial, connective, muscle, and nervous tissues.
    • Organ Level: Combinations of two or more tissues functioning together.
    • Organ System Level: Related organs performing a common function.
    • Organism Level: The sum of all systems forming a living human.

    Organ Systems of the Human Body

    • Integumentary System: Protects the body from injury, infection, and dehydration.
    • Skeletal System: Supports the body, protects organs, and allows movement.
    • Muscular System: Facilitates movement, maintains posture, and generates heat.
    • Cardiovascular System: Transports nutrients, gases, and wastes throughout the body.
    • Respiratory System: Facilitates gas exchange (oxygen and carbon dioxide) between the body and environment.
    • Lymphatic and Immune Systems: Protects against pathogens and aids in transport.

    Characteristics of Living Humans

    • Living organisms exhibit distinct processes that differentiate them from non-living items, including growth, reproduction, and response to stimuli.

    Anatomical Terminology

    • A running vocabulary list is essential for mastering human anatomy language, as slight changes in spelling can lead to different meanings.
    • Example: Ilium vs. Ileum; Peritoneum vs. Perineum; Hemostasis vs. Homeostasis.

    Directional Terms and Body Position

    • Recognize terms like anterior/posterior, superior/inferior, medial/lateral to describe positioning in the body.
    • Practice example: The intestine is inferior to the lungs.

    Planes and Sections

    • Sagittal Plane: Divides body into left and right sections.
    • Coronal Plane: Divides body into anterior and posterior portions.
    • Transverse Plane: Divides body into superior and inferior parts.
    • Oblique Plane: Cuts through the body at diverse angles.

    Body Cavities

    • Body cavities protect and separate organs; major cavities include thoracic and abdominopelvic.
    • Serous Membranes: Double-layered membranes with visceral and parietal layers to reduce friction through peritoneal fluid.

    Specific Cavity Information

    • Thoracic Cavity: Contains pericardium (heart) and pleura (lungs).
    • Abdominopelvic Cavity: Separated by the diaphragm; contains abdominal and pelvic cavities with associated serous membranes.

    Abdominopelvic Regions and Quadrants

    • Two methods used for organ location: divided into nine regions or four quadrants.

    Medical Imaging

    • Various imaging techniques exist, each with unique workings, applications, advantages, and disadvantages. Self-study is required for detailed comprehension.
