MEMBRANA LIMITANS Meaning and
Definition
-
Membrana limitans refers to a thin, limiting membrane found in various anatomical structures, particularly in the human body. The term "membrana" is derived from the Latin word for membrane, while "limitans" comes from the Latin word limitans, meaning limiting or bounding.
This term is commonly used in the field of biology and anatomy to describe a specific type of membrane that acts as a boundary or barrier between different tissues or compartments within an organ or structure. It can be composed of different types of cells, proteins, or connective tissues depending on the specific location and function.
In certain anatomical structures, such as the eyes or the inner ear, membrana limitans can be found delineating the boundaries of specific compartments or layers. For example, in the retina of the eye, the membrana limitans is a boundary between the innermost layer, known as the neural retina, and the neighboring layer called the retinal pigment epithelium.
The presence and integrity of the membrana limitans are vital for maintaining the structural and functional organization of tissues and organs. It acts as a mechanical barrier, providing support and separating different compartments, while also allowing certain substances or cells to pass through selectively. The composition and properties of the membrana limitans can vary depending on the tissue and its specific functions.

One of two layers of the retina, m. l. interna, or investing membrane, and the m. l. externa, between the nuclear layer and the layer of rods and cones.

Etymology of MEMBRANA LIMITANS
The word "membrana limitans" is derived from Latin.
"Membrana" refers to a membrane or a thin layer of tissue that forms a boundary or lining. It comes from the Latin word "membrana", which means membrane or skin.
"Limitans" is the present participle of the verb "limitare" in Latin, which translates to "to limit" or "to bound".
Therefore, "membrana limitans" can be understood to mean "limiting membrane" or "boundary membrane". It is a term used in anatomy and refers to a specific structure or membrane that acts as a boundary or limit within a given context.
