Izomrétegbl

Izomrétegbl is a term that appears in some Hungarian-language anatomy resources to denote a proposed sublayer within skeletal muscle tissue. The name combines izom (muscle) and réteg (layer), with the suffix bl appearing in certain glossaries. In sources where it is used, izomrétegbl is described as a laminar subdivision within a muscle, distinct from the established connective tissue layers that surround muscle fibers and fascicles.

The exact anatomical position of izomrétegbl varies by author, with different descriptions placing it as a narrow lamina between fascicles or as a conceptual layer within the endomysial network that organizes fiber packing. The term is not standard in English-language anatomy and is not universally accepted; there is no broad consensus on its histological criteria, boundaries, or functional relevance.

In relation to known structures, the term is sometimes discussed alongside the endomysium, perimysium, and epimysium, the connective tissue layers that envelop individual fibers, fascicles, and the entire muscle, respectively. When invoked, izomrétegbl is typically proposed to exhibit a distinct arrangement of fibers or connective tissue that could influence local mechanical properties or microvascular organization, though these ideas remain speculative and not widely validated.

Due to limited adoption, izomrétegbl is not a routinely taught or widely cited term in contemporary anatomy references. If used, it would benefit from standardized definitions and corroborating histological evidence to establish its precise location, structural characteristics, and potential functional significance.
