    Study Notes

    Anatomy Nomenclature

    • Anatomy is the science of the structure and function of the body.
    • Basic anatomy is the study of the minimal amount of anatomy consistent with the understanding of the overall structure and function of the body.
    • Clinical anatomy is the study of the macroscopic structure and function of the body as it relates to the practice of medicine and other health sciences.

    Anatomical Position

    • The body is erect, eyes face forward, arms are kept by the side with palms facing forward, and legs are kept together with feet directed forward.
    • This is the standard position for describing the human body.

    Planes of the Body

    • Median sagittal plane: a vertical plane passing through the center of the body, dividing it into equal right and left halves.
    • Paramedian planes: planes situated to one or the other side of the median plane and parallel to it.
    • Sagittal plane definition: a structure situated nearer to the median plane of the body than another is said to be medial to the other, and vice versa.
    • Frontal (coronal) planes: imaginary vertical planes at right angles to the median plane, dividing the body into anterior and posterior parts.
    • Horizontal (transverse) planes: at right angles to both the median and the coronal planes, dividing the body into superior and inferior parts.

    Terms of Orientation

    • Anterior and posterior: used to indicate the front and back of the body, respectively.
    • Palmar and dorsal surfaces: used in place of anterior and posterior when describing the hand.
    • Plantar and dorsal surfaces: used in place of lower and upper surfaces when describing the foot.
    • Proximal and distal: describe the relative distances from the roots of the limbs.
    • Superficial and deep: denote the relative distances of structures from the surface of the body.
    • Superior and inferior: denote levels relatively high or low with reference to the upper and lower ends of the body.
    • Internal and external: used to describe the relative distance of a structure from the center of an organ or cavity.

    Terms of Direction

    • Ipsilateral: refers to the same side of the body.
    • Contralateral: refers to opposite sides of the body.

    Body Positions

    • Supine position: lying on the back.
    • Prone position: lying face downward.

    Anatomical Position and Planes

    • The body is erect, with eyes facing forward, arms kept by the side with palms facing forward, and legs together with feet directed forward.
    • Frontal planes are imaginary vertical planes at right angles to the median plane, dividing the body into anterior and posterior parts.
    • Coronal planes are imaginary vertical planes at right angles to the median plane, dividing the body into anterior and posterior parts.
    • Horizontal or transverse planes are at right angles to both the median and coronal planes, dividing the body into superior and inferior parts.

    Anatomical Directions

    • Anterior refers to the front of the body, while posterior refers to the back of the body.
    • Palmar surfaces refer to the front of the hand, while dorsal surfaces refer to the back of the hand.
    • Plantar surfaces refer to the bottom of the foot, while dorsal surfaces refer to the top of the foot.
    • Proximal refers to the relative distance from the roots of the limbs, while distal refers to the distance away from the roots.

    Anatomical Movements

    • Pronation of the forearm is a medial rotation of the forearm, causing the palm of the hand to face posteriorly.
    • Supination of the forearm is a lateral rotation of the forearm from the pronated position, causing the palm of the hand to face anteriorly.
    • Circumduction is the combination of flexion, extension, abduction, and adduction movements.
    • Protraction is moving forward, while retraction is moving backward.
    • Inversion is the movement of the foot so that the sole faces in a medial direction, while eversion is the opposite movement.
    • Opposition is the combination of abduction, medial rotation, and flexion, typically occurring in the thumb.

    Anatomical Terminology

    • Superficial and deep denote the relative distances of structures from the surface of the body.
    • Superior and inferior denote levels relatively high or low with reference to the upper and lower ends of the body.
    • Internal and external describe the relative distance of a structure from the center of an organ or cavity.
    • Ipsilateral refers to the same side of the body, while contralateral refers to opposite sides of the body.

    Body Positions

    • The supine position is lying on the back, while the prone position is lying face downward.
