    Study Notes

    Anatomical Planes & Directions

    • Coronal (Frontal) Plane: Divides the body into anterior (front) and posterior (back) sections.
    • Median Plane: Divides the body into equal right & left halves.
    • Sagittal Plane: Parallel to the median plane, divides the body into unequal right and left sections.
    • Transverse Plane: Perpendicular to the median & coronal planes, divides the body into superior (upper) and inferior (lower) sections.

    Anatomical Directional Terms

    • Superior: Above or higher in position; towards the head
    • Inferior: Below or lower in position; towards the feet
    • Cranial or Cephalic: In the embryo, in animals, the term refers to toward the head.
    • Caudal: In the embryo and animals, the term refers to towards the tail.
    • Anterior: Front of the body or nearer to it; also known as "ventral"
    • Posterior: Back of the body or nearer to it; also known as "dorsal".
    • Medial: Nearer to the median plane.
    • Lateral: Away from the median plane.
    • Intermediate: Between a medial and lateral point.
    • Proximal: Nearer to the origin of the limb (attachment to the trunk).
    • Distal: Away from the origin of the limb.
    • Ipsilateral: Same side of the body.
    • Contralateral: Opposite side of the body.
    • Superficial: Nearer the body's surface.
    • Deep: Away from the body's surface; towards the inside of the body.
    • Internal: Nearer the cavity of the viscus.
    • External: Away from the cavity of the viscus.
    • Supine Position: Ventral surface faces up.
    • Prone Position: Ventral surface faces down.

    Anatomical Movements

    • Flexion: Decreasing the angle between bones or body parts.
    • Extension: Increasing the angle between bones or body parts.
    • Dorsiflexion: Flexion at the ankle joint.
    • Plantarflexion: Turning the foot or toes towards the plantar surface.
    • Adduction: Movement of the limb medially towards the median plane.
    • Abduction: Movement of the limb laterally away from the median plane.
    • Circumduction: Combination of flexion, abduction, extension, and adduction movements.
    • Rotation:
      • Medial Rotation: Movement of a ventral surface towards the median plane.
      • Lateral Rotation: Movement of a ventral surface away from the median plane.
    • Pronation: Medial rotation of the forearm, turning the palm of the hand backwards.
    • Supination: Lateral rotation of the forearm, turning the palm of the hand forwards.
    • Opposition: Movement of the thumb pad to touch another digit pad.
    • Protrusion: Movement anteriorly (forward).
    • Retrusion: Movement posteriorly (backward).
    • Elevation: Raising or moving a part superiorly.
    • Depression: Lowering or moving a part inferiorly.
    • Inversion: Sole of the foot directed inwards.
    • Eversion: Sole of the foot directed outwards.

    Anatomy's Branches

    • Gross (Macroscopic) Anatomy: Study of structures visible to the naked eye. This includes:
      • Regional Anatomy: Examining all structures in a particular region of the body.
      • Systemic Anatomy: Studying structures of a particular system (e.g., musculoskeletal, cardiovascular).
    • Microscopic Anatomy (Histology): Study of cells and tissues using a microscope.
    • Developmental Anatomy: Tracing structural changes throughout the lifespan.
    • Embryology: Developmental anatomy focusing on changes before birth.
    • Surface Anatomy: Study of internal structures as they relate to the skin surface.
    • Clinical Anatomy: Applying anatomical knowledge to diagnosis and treatment.
    • Radiographic Anatomy: Studying internal structures visualized by X-ray images or specialized scanning procedures.
    • Pathological Anatomy: Studying structural changes caused by disease.

    Levels of Structural Organization

    • Chemical Level: Atoms, molecules, macromolecules, organelles, and the cell.
    • Cellular Level: Cells.
    • Tissue Level: Groups of similar cells functioning together, forming epithelial, connective, muscular, and nervous tissues.
    • Organ Level: Groups of different tissues working together to perform a specific function (e.g., kidneys, bones, liver, lungs).
    • Organ System Level: Groups of organs working together (e.g., digestive system, cardiovascular system).
    • Organism Level: All organ systems combined, the highest level of organization in a living being.

    Anatomical Position

    • Standing Erect: Eyes looking forward, arms at the sides with palms facing forward, feet close together, toes pointing forward.
