Ventrikelin

Ventrikelin is not a standard term in English medical nomenclature. Depending on language and context, it may be used informally to denote the ventricular lining or to name a hypothetical substance associated with a ventricle. As such, ventrikelin does not refer to a single, universally defined structure or molecule.

In neuroanatomy, the ventricular lining refers to the ependymal layer that lines the brain’s ventricular system. Ependymal cells form the ependyma, participate in cerebrospinal fluid production and circulation, and act as a selective barrier between cerebrospinal fluid and neural tissue. This lining plays a role in maintaining the chemical environment necessary for neural function.

In the heart, the ventricular lining is primarily the endocardium, a thin, endothelial tissue that lines the interior of the ventricles and cardiac chambers. The endocardium protects myocardium, participates in interactions with the valvular apparatus, and contributes to the regulation of myocardial perfusion and electrical conduction.

Beyond anatomy, ventrikelin may appear as a proposed protein, gene name, or fictional term, but no widely accepted real-world entity carries this name in major biological databases. If ventrikelin is intended in a specific language, field, or fictional context, providing that information would allow a more precise and targeted article. See also ventricular system, ependyma, and endocardium for related concepts.
