Elongation
Elongation (medicine)
Elongation (pronunciation: /iːˌlɒŋˈɡeɪʃən/) is a term used in various fields of medicine to describe the process or result of making something longer, or the state of being pulled out or stretched.
Etymology
The term "elongation" is derived from the Latin "elongare", which means "to lengthen out". It is composed of "e-" (out) and "longus" (long).
In Anatomy
In anatomy, elongation often refers to the lengthening of a muscle or tendon. This can occur naturally as part of growth or development, or it can be induced artificially through certain exercises or surgical procedures.
In Genetics
In genetics, elongation refers to a phase of protein synthesis and DNA replication where the DNA or RNA chain is extended. During this process, the enzymes DNA polymerase and RNA polymerase add nucleotides to the growing chain.
In Radiology
In radiology, elongation refers to the apparent lengthening of an object in an image due to the angle of projection. This is a common phenomenon in X-ray imaging.
