    Study Notes

    Basic Concepts in Anatomy

    • Atoms consist of subatomic particles: protons, electrons, and neutrons.
    • Molecules form when two or more elements combine, e.g., water, proteins, and sugars.
    • Molecules are the chemical building blocks of body structures.

    Levels of Organization

    • Chemical Level: Comprises particles, atoms, and molecules that are fundamental building blocks of matter.
    • Cellular Level: The cell is the smallest unit of living matter; humans are multicellular organisms.

    Major Body Structures

    • Skin: Covers the body and provides protection.
    • Fasciae: Connects skin to underlying structures; divided into superficial fascia (subcutaneous tissue) and deep fascia (membranous connective tissue covering muscles).
    • Muscles: Three types –
      • Skeletal (voluntary, striated)
      • Smooth (involuntary, non-striated)
      • Cardiac (involuntary, striated)
    • Joints/Articulations: Junctions between two or more bones; classified into:
      • Fibrous Joints: Joined by fibrous tissue
      • Cartilaginous Joints: Joined by cartilage
      • Synovial Joints: Covered with hyaline cartilage and separated by joint cavity.

    Ligaments

    • Connective tissue structures uniting bones; composed of:
      • Collagen fibers (inelastic)
      • Elastic fibers (stretchable)

    Bursae

    • Fluid-filled sacs that reduce friction between tendons and bones, found near joints.

    Types of Cartilage

    • Hyaline Cartilage
    • Fibro Cartilage
    • Elastic Cartilage

    Minor Body Cavities

    • Orbital Cavity: Houses the eyes (orbits).
    • Nasal Cavity: Contains receptors for the sense of smell (olfaction).
    • Buccal/Oral Cavity: Contains the tongue, teeth, palate, and tonsils.

    Body Cavities

    • The body is divided into major cavities for organ systems:
      • Ventral Cavity includes the thoracic cavity (lungs, heart) and pericardium.

    Scientific Approach to Anatomy

    • Gross anatomy: Study of body shapes and structures with the unaided eye.
    • Approaches to anatomy: Topographical, systematic, and clinical.
    • Common international terminology is used for anatomical descriptions.
