Study Notes
Introduction to Human Anatomy
- Coronal plane divides the body into anterior (front) and posterior (back) sections.
- Understanding anatomy is crucial for clinicians to identify affected structures in diseases, during examinations, and surgeries.
Learning Outcomes
- Identify subdivisions of anatomy.
- Enumerate body regions and systems.
- Describe anatomical planes, positions, and movements.
Levels of Structural Organization
- Organ Systems: Groups of organs (e.g., digestive system) that work together.
- Basic Cell Types: Neuron, muscle, epithelial, and connective tissue cells.
- Basic Cell Functions: Include metabolism, responsiveness, movement, growth, differentiation, and reproduction.
- Homeostasis: Dynamic process maintaining internal stability despite external changes.
Tissues
-
Epithelial Tissue:
- Polyhedral cells with minimal interstitial space.
- Covers skin and lines body cavities (lungs, GI tract, urinary, reproductive systems).
- Capable of high regeneration; forms exocrine and endocrine glands.
-
Connective Tissue:
- Major components include non-cellular elements (collagen, elastin, and reticular fibers) and cellular components (blood cells, fibroblasts).
- Functions: Support, protection, transport, energy storage, and defense.
- Types:
- Loose connective tissue (areolar, blood, adipose).
- Dense connective tissue (cartilage, bone, tendons, ligaments).
Body Membranes
- Two types:
- Epithelial Membranes: Cutaneous, mucous, serous.
- Connective Tissue Membranes.
Subdivisions of Anatomy
- Gross Anatomy: Study of visible structures.
- Cross-Sectional Anatomy: Examines body sections.
- Surface Anatomy: Study of external body features.
- Microscopic Anatomy (Histology): Study of tissues.
- Developmental Anatomy (Embryology): Study of body development.
- Radiographic Anatomy: Study via imaging.
- Clinical Anatomy: Application in medical practice.
- Regional Anatomy: Study of specific body areas (e.g., limbs).
- Systemic Anatomy: Study based on body systems.
Anatomical Terms and Positions
- Anatomical Position: Erect stance with feet flat, arms at sides, palms, face, and eyes forward.
- Supine and Prone Positions: Supine - lying on back; Prone - lying on stomach.
Anatomical Planes
- Sagittal Plane: Divides body into left and right sections.
- Frontal Plane (Coronal Plane): Divides into anterior and posterior sections.
- Transverse Plane: Divides into superior and inferior sections.
- Oblique Plane: Divides at an angle.
Anatomical Movements
- Flexion: Decreases angle between bones.
- Extension: Increases angle between bones.
- Abduction: Movement away from the midline.
- Adduction: Movement towards the midline.
- Circumduction: Circular movement of a limb.
- Medial Rotation: Inward rotation towards the midline.
- Lateral Rotation: Outward rotation away from the midline.
Specific Movements
- Pronation: Forearm rotation so palm faces down.
- Supination: Forearm rotation so palm faces up.
- Inversion: Movement of foot sole towards the midline.
- Eversion: Movement of foot sole away from the midline.
- Elevation: Movement of body part superiorly.
- Depression: Movement of body part inferiorly.
