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 ...
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.
Proximal and distal, which describe a position that is closer to (proximal) or farther from (distal) the trunk of the body. [12] 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.
Distal causation: explanation of human social behaviour by considering the larger context in which individuals carry out their actions. Proponents of the distal view of power argue that power operates at a more abstract level in the society as a whole (e.g. between economic classes) and that "all of us are affected by both types of power ...
Together, distal and proximal stressors accrue over time, leading to chronically high levels of stress that cause poor health outcomes. Thus, minority stress theory has three primary tenets: Minority status leads to increased exposure to distal stressors. Minority status leads to increased exposure to proximal stressors, due to distal stressors.
The distal convoluted tubule has a different structure and function to that of the proximal convoluted tubule. Cells lining the tubule have numerous mitochondria to produce enough energy for active transport to take place. Much of the ion transport taking place in the distal convoluted tubule is regulated by the endocrine system.
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 ...
Words relating to spatial deixis can be proximal (near, such as English [right] here or this), medial (near the addressee, such as English [over] there or that), distal (far, such as English [out] there or that), far-distal (far from both the speaker and addressee, such as archaic English yon and yonder).
