    Anatomical Position

    • The standing position with arms hanging by the sides, palms facing forward, legs parallel, and feet flat is known as anatomical position.

    • Longitudinal sections cut through the body from head to toe, primarily through the sagittal plane.
    • Transverse sections give a cross-section of the body, perpendicular to its long axis.

    Anatomical Terminology

    • Superior refers to a structure that is higher up compared to another structure.
    • Inferior refers to a structure that is lower down compared to another structure.
    • Anterior refers to the front of the body.
    • Posterior refers to the back of the body.
    • Medial refers to the middle or center of the body.
    • Lateral refers to the sides of the body.
    • Proximal refers to a point closer to the trunk or point of origin of a limb.
    • Distal refers to a point further away from the trunk or point of origin of a limb.

    Anatomical Cavities

    • The cranial cavity is located in the head, housing the brain.
    • The thoracic cavity is located in the chest and contains the mediastinum, lungs, and heart.
    • The abdominopelvic cavity is located in the lower trunk and includes the abdominal cavity and pelvic cavity.
    • The diaphragm separates the thoracic and abdominopelvic cavities.

    Regions of the Abdomen

    • The abdomen is divided into nine regions: right hypochondriac, epigastric, left hypochondriac, right lumbar, umbilical, left lumbar, right inguinal, pubic, and left inguinal.
    • The abdominal regions are used to describe the location of organs.

    Regions of the Upper Limb

    • The regions of the upper limb include the deltoid, shoulder, scapular, axillary, arm, elbow, cubital fossa, forearm, carpal, wrist, hand, and palm.
    • The upper limb regions are divided into compartments of muscles that work together to allow for complex movements.

    Regions of the Lower Limb

    • The regions of the lower limb include the gluteal, hip, thigh, knee, popliteal fossa, leg, ankle, foot, and plantar surface.
    • Like the upper limb, the lower limb regions are divided into compartments of muscles that help facilitate weight bearing and lower limb movements.

    Movements

    • Abduction: Movement away from the midline of the body or limb.
    • Adduction: Movement toward the midline of the body or limb.
    • Flexion: Decreasing the angle between two bones.
    • Extension: Increasing the angle between two bones.
    • Rotation: Movement of a bone around its longitudinal axis.
    • Dorsiflexion: Movement of the foot upwards toward the shin.
    • Plantarflexion: Movement of the foot downward, pointing the toes.
    • Eversion: Moving the sole of the foot away from the midline of the body.
    • Inversion: Moving the sole of the foot towards the midline of the body.

    Compound Movements

    • Circumduction: A combination of flexion, extension, abduction, and adduction resulting in a circular movement of a limb.
    • Opposition: Movement of the thumb to touch the fingers of the same hand.
    • Reposition: Movement of the thumb to its anatomical position.
