theca interna
This term is a specialized anatomical designation used primarily in histology and endocrinology. It describes a specific cellular layer of the ovarian follicle, distinguishing it from the theca externa. The term carries a neutral, clinical tone and is used exclusively in medical or biological research contexts.
As a Latin-derived anatomical term, it follows specific naming conventions where theca refers to the sheath or case and interna specifies the inner position. In professional literature, it is treated as a singular anatomical entity.
Meanings
The vascularized inner layer of the theca, a protective sheath or capsule surrounding an organ or structure, most commonly referring to the inner layer of the ovarian follicle wall that produces androgens.
