Study Notes
Anatomical Planes
- Coronal (Frontal) Plane: Vertical plane dividing the body into anterior (front) and posterior (back) parts.
- Sagittal Plane: Vertical plane dividing the body into left and right sections; viewed from the side.
- Transverse (Horizontal) Plane: Divides the body into superior (upper) and inferior (lower) parts.
Directional Terms
- Superior: Indicates a position above or toward the head.
- Inferior: Indicates a position below or toward the feet.
- Cranial (Cephalic): Pertaining to the skull; directed toward the head.
- Caudal: Pertaining to the tail; directed toward the tail end.
- Anterior (Ventral): Position on the front side of the body.
- Posterior (Dorsal): Position on the back side of the body.
- Medial: Closer to the median plane.
- Lateral: Further from the median plane.
- Intermediate: Between a medial and lateral point.
- Proximal: Closer to the attachment of a limb to the trunk.
- Distal: Further from the attachment of a limb to the trunk.
- Ipsilateral: On the same side of the body.
- Contralateral: On the opposite side of the body.
- Superficial: Closer to the body surface.
- Deep: Further away from the body surface.
- Internal: Closer to the cavity of a visceral organ.
- External: Further from the cavity of a visceral organ.
Anatomical Position
- Standard reference position: standing erect, facing forward, arms at sides with palms facing forward, feet close together and toes pointing forward.
Types and Subdivisions of Anatomy
- Gross (Macroscopic) Anatomy: Structures visible without a microscope; typically learned through dissection.
- Regional Anatomy: Focused study of specific body regions.
- Systemic Anatomy: Study of specific body systems.
- Microscopic Anatomy (Histology): Study of cells and tissues using microscopy.
- Developmental Anatomy: Observes changes throughout the lifespan; including embryology.
- Surface Anatomy: Examines internal structures based on the skin surface.
- Clinical Anatomy: Application of anatomical knowledge to clinical practice.
- Radiographic Anatomy: Studies internal structures via imaging techniques.
- Pathological Anatomy: Investigates structural changes due to diseases.
Levels of Structural Organization
- Chemical Level: Consists of atoms, molecules, macromolecules, organelles, and cells.
- Cellular Level: Cells are the basic living units.
- Tissue Level: Groups of cells working together (four types: epithelial, connective, muscular, and nervous).
- Organ Level: Organization of tissues into organs (e.g., kidneys, liver).
- Organ System Level: Different organs work together as a system.
- Organism Level: All systems contribute to form a living human being.
Anatomical Movements
- Flexion: Decreases angle between bones.
- Extension: Increases angle between bones.
- Dorsiflexion: Flexion at the ankle, lifting toes.
- Plantarflexion: Turning the foot or toes downward.
- Adduction: Movement toward the median plane.
- Abduction: Movement away from the median plane.
- Circumduction: Circular movement combining flexion, extension, abduction, and adduction.
- Rotation:
- Medial Rotation: Movement toward the median plane.
- Lateral Rotation: Movement away from the median plane.
- Pronation: Medial rotation of the forearm; palm turns backward.
- Supination: Lateral rotation of the forearm; palm faces forward.
- Opposition: Thumb meets another digit.
- Protrusion: Movement anteriorly (forward).
- Retrusion: Movement posteriorly (backward).
- Elevation: Movement superiorly.
- Depression: Movement inferiorly.
- Inversion: Sole of the foot turned inward.
- Eversion: Sole of the foot turned outward.
