Isthmic-

Isthmic is a name that can be used to describe various concepts in medicine and biology. It comes from the Greek word “isthmos”, which means “isthmus” or “narrow passage”.

In medicine, isthmic means a narrow passage between two organs or tissues. For example, the isthmic-uterine diaphragm is a muscular layer that separates the uterus from the vagina. The isthmic-cervical zone is the area of ​​the cervix that is located in front of the entrance to the uterus.

Isthmic- can also be used to designate narrow passages in other organs or systems of the body. For example, in the lungs there are isthmic-bronchial tubes that connect the bronchi to the alveoli. The intestines have isthmic-intestinal valves that regulate the movement of food.

Additionally, isthmico- is used in biochemistry to refer to the narrow passage between molecules in proteins or DNA. For example, when proteins are formed on ribosomes, amino acids are synthesized through a narrow passage called isthmo-aminoacyltransferase.

Thus, isthmic is an important term in medicine and biochemistry, which describes narrow passages between various organs and systems of the body.
