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.
