The term "membranous commissura" is commonly used in anatomy to refer to a thin connective tissue that connects different parts of the brain. Its spelling can be explained using the International Phonetic Alphabet (IPA) symbols. The pronunciation of "membranous" is /ˈmɛm.brə.nəs/, with stress on the second syllable. The pronunciation of "commissura" is /kəˈmɪs.ʊr.ə/, with stress on the third syllable. When combined, the word is pronounced /mɛm.brə.nəs kəˈmɪs.ʊr.ə/. Understanding IPA can help in correctly spelling and pronouncing medical terms.
The term "membranous commissura" refers to a structure in biology characterized by its membranous nature and its function as a type of commissure. A commissure is a bundle of nerve fibers that connects corresponding structures in different parts of the nervous system, allowing for communication and coordination between them.
In this context, the membranous commissura specifically denotes a commissure that is composed predominantly of membranes or membrane-like tissues. Membranes are thin, pliable layers or sheets of tissue that serve various functions, such as providing structural support, enclosing and protecting organs, or facilitating the exchange of substances across their surfaces.
The membranous commissura can be found within different anatomical systems, such as the nervous system or certain organs. For example, in the central nervous system, this commissure may refer to a connecting structure between two parts of the brain or spinal cord, where adjacent nerve fibers are enveloped or sheathed by membranes. It serves as a conduit for signals to pass between the two halves of the nervous system, allowing for coordinated function and integration of information.
Overall, the membranous commissura is a biological structure consisting mainly of membranes that enables communication and connectivity between corresponding structures in different parts of an organism's body, aiming to promote coordination and functional integration.

The word "membranous" originated from the Latin term "membrāna", meaning "membrane". "Commissura" also has Latin origins and refers to a joining or connection.
