The opposite end then becomes the posterior end. [44] Properly, this terminology would apply only to an organism that is always planktonic (not normally attached to a surface), although the term can also be applied to one that is sessile (normally attached to a surface).
Anterior and posterior, which describe structures at the front (anterior) and back (posterior) of the body. For example, the toes are anterior to the heel, and the popliteus is posterior to the patella. [1] Superior and inferior, which describe a position above (superior) or below (inferior) another part of the body. For example, the orbits are ...
However, inferior to the midbrain-diencephalic junction the term dorsal is synonymous with posterior and ventral is synonymous with anterior. [1] Contralateral and ipsilateral referring to a corresponding position on the opposite left or right side (the sagittal plane) and on the same side (ipsilateral) respectively.
Posterior analytics (a posteriori) is about inductive logic, which comes from observational evidence. Both terms appear in Euclid's Elements and were popularized by Immanuel Kant's Critique of Pure Reason, an influential work in the history of philosophy. [1] Both terms are primarily used as modifiers to the noun knowledge (e.g., a priori ...

The term posterior teeth refers to premolars and molars, as opposed to incisors and canines, which are anterior teeth. [1] [5] Proximal The surfaces of teeth that normally lie adjacent to another ...

Buttocks, as a euphemism; Posterior horn (disambiguation) Posterior probability, the conditional probability that is assigned when the relevant evidence is taken into account; Posterior tense, a relative future tense
Parallel are the anterior axillary line, which passes through the anterior axillary skinfold, and the posterior axillary line, which passes through the posterior axillary skinfold. The mid-clavicular line , a line running vertically down the surface of the body passing through the midpoint of the clavicle .
Extension is the opposite of flexion, a straightening movement that increases the angle between body parts. [12] For example, when standing up, the knees are extended. When a joint can move forward and backward, such as the neck and trunk, extension is movement in the posterior direction. [10]
