  2. Anatomical terms of location - Wikipedia

    en.wikipedia.org/wiki/Anatomical_terms_of_location

    Thus the upper arm in humans is proximal and the hand is distal. "Proximal and distal" are frequently used when describing appendages, such as fins, tentacles, and limbs. Although the direction indicated by "proximal" and "distal" is always respectively towards or away from the point of attachment, a given structure can be either proximal or ...

  3. Interphalangeal joints of the hand - Wikipedia

    en.wikipedia.org/wiki/Interphalangeal_joints_of...

    Anatomically, the proximal and distal interphalangeal joints are very similar. There are some minor differences in how the palmar plates are attached proximally and in the segmentation of the flexor tendon sheath, but the major differences are the smaller dimension and reduced mobility of the distal joint.

  4. Anatomical terms of neuroanatomy - Wikipedia

    en.wikipedia.org/wiki/Anatomical_terms_of_neuro...

    Standard terms used throughout anatomy include anterior / posterior for the front and back of a structure, superior / inferior for above and below, medial / lateral for structures close to and away from the midline respectively, and proximal / distal for structures close to and far away from a set point.

  5. Anatomical terminology - Wikipedia

    en.wikipedia.org/wiki/Anatomical_terminology

    Proximal and distal, which describe a position that is closer to (proximal) or farther from (distal) the trunk of the body. [1] For example, the shoulder is proximal to the arm, and the foot is distal to the knee. Superficial and deep, which describe structures that are closer to (superficial) or farther from (deep) the surface of the body.

  6. Interphalangeal joints of the foot - Wikipedia

    en.wikipedia.org/wiki/Interphalangeal_joints_of...

    The rest of the toes each have three phalanx bones (proximal, middle, and distal phalanges), so they have two interphalangeal joints: the proximal interphalangeal joint between the proximal and middle phalanges (abbreviated "PIP joint") and the distal interphalangeal joint between the middle and distal phalanges (abbreviated "DIP joint").

  7. Comparative foot morphology - Wikipedia

    en.wikipedia.org/wiki/Comparative_foot_morphology

    The foot structures are divided into segments from proximal to distal and are grouped according to similarity in shape, dimension and function. In this approach, the foot may be described in three segments: as the hindfoot, midfoot and forefoot. The hindfoot is the most proximal and posterior portion of the foot. [22]

  8. Right coronary artery - Wikipedia

    en.wikipedia.org/wiki/Right_coronary_artery

    Proximal: starting at RCA origin, spanning half the distance to the acute margin [6] [7]; Middle: from proximal segment to the acute margin [6] [7]; Distal: from middle segment to origination point of the posterior interventricular artery, where the posterior interventricular sulcus meets the atrioventricular groove on the base of the heart.

  9. Trochlea of humerus - Wikipedia

    en.wikipedia.org/wiki/Trochlea_of_humerus

    The elbow is a hinge joint with a rotatory component where the trochlea forms the convex, proximal surface which articulates with the concave, distal surface on the ulna, the trochlear notch. While the trochlea together with its associated fossae almost covers a 360° angle, the trochlear notch on the ulna forms a 190° arc and the gap in ...
