Anatomy is often described in planes, referring to two-dimensional sections of the body. A section is a two-dimensional surface of a three-dimensional structure that has been cut. A plane is an imaginary two-dimensional surface that passes through the body. Three planes are commonly referred to in anatomy and medicine: [1] [2]: 4
(affinis): having affinity with, similar but not identical to; auct. : of the authors; indicates that a name is used in the sense of subsequent authors, and not in the sense of the original author; Ca. : for candidate names of organisms that have not been completely accepted
Affinity (taxonomy) – mainly in life sciences or natural history – refers to resemblance suggesting a common descent, phylogenetic relationship, or type. [1] The term does, however, have broader application, such as in geology (for example, in descriptive and theoretical works [2] [3]), and similarly in astronomy (for example, see "Centaur object" in the context of 2060 Chiron's close ...
An anatomical variation, anatomical variant, or anatomical variability is a presentation of body structure with morphological features different from those that are typically described in the majority of individuals.
Receptor Phosphorylation is another type of receptor down-regulation. Biochemical changes can reduce receptor affinity for a ligand. [41] Reducing the sensitivity of the receptor is a result of receptors being occupied for a long time. This results in a receptor adaptation in which the receptor no longer responds to the signaling molecule.
In immunology, affinity maturation is the process by which T FH cell-activated B cells produce antibodies with increased affinity for antigen during the course of an immune response. With repeated exposures to the same antigen, a host will produce antibodies of successively greater affinities .
These cells are eosinophilic or "acid-loving" due to their large acidophilic cytoplasmic granules, which show their affinity for acids by their affinity to coal tar dyes: Normally transparent, it is this affinity that causes them to appear brick-red after staining with eosin, a red dye, using the Romanowsky method.

Many pathologists who practice in this setting are trained and certified in both anatomical pathology and clinical pathology, which allows them to supervise blood banks, clinical chemistry laboratories, and medical microbiology laboratories as well. Large corporate providers of anatomical pathology services, such as AmeriPath in the United ...
