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 ...
Proximal The surfaces of teeth that normally lie adjacent to another tooth. Proximal includes both mesial and distal, such as when referring to the proximal surfaces of teeth. [1] Quadrant Dental quadrants The dentition is divided into four quarters. The two dental arches form an oval, which is divided into quadrants which are numbered from 1 ...
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.
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.
Feet and ankles (52 bones) - Left and right tarsals (14) (ankle), metatarsals (10) (foot), proximal phalanges(10), intermediate phalanges (8) and distal phalanges (10) . Through anatomical variation, the appendicular skeleton may have an accessory bone. Examples include sesamoids in the hands and feet. Some occurrences are rarer than others.
The distal half of the limb proper has two long bones, together termed the zeugopodium (plural: zeugopodia). These may be radius and ulna of the forearm , or the tibia and fibula of the shin. The distalmost portion or extremity of the limb, i.e. the hand or foot , is known as the autopodium (plural: autopodia ).
