How Do You Spell PERINEURIUM?

Pronunciation: [pˌɛɹɪnjˈuːɹi͡əm] (IPA)

The word "perineurium" relates to the connective tissue that surrounds nerve fibers. Its spelling can be explained using the International Phonetic Alphabet (IPA) transcription as /ˌpɛrɪˈnjʊərɪəm/. The "per" at the beginning is pronounced with a short "e" sound, followed by "ri" which uses a mid-central vowel. The "neu" in the middle is pronounced with a "u" sound, followed by "ri" which uses a short "i" sound. The word ends with "-ium" pronounced as "ee-um". Overall, the spelling of this word reflects its Greek origin, "peri" meaning "around" and "neuron" meaning "nerve".

PERINEURIUM Meaning and Definition

1. Perineurium is a term used in neuroanatomy and refers to the connective tissue surrounding a nerve fascicle. It is one of the three layers of protective tissues that encapsulate and support nerves in the peripheral nervous system.

   The perineurium functions as a durable sheath, forming a physical barrier that separates and isolates individual nerve fascicles within a larger nerve. It is composed of multiple layers of flat, elongated cells called perineurial cells. These cells are tightly connected and have specialized tight junctions between them, which provides strength and helps maintain the integrity of the nerve fascicle. The perineurium also contains blood vessels that supply nutrients to the nerve tissue.

   The main role of the perineurium is to provide structural support and protection to the nerve fibers within the fascicle, as well as regulate the movement of substances between the nerve fibers and the surrounding tissues. It acts as a selective barrier, preventing larger molecules and substances from easily entering or leaving the nerve fascicle.

   Overall, perineurium is an essential component in the organization and proper functioning of peripheral nerves. It helps maintain the structural integrity of the nerve fascicles and contributes to the overall health and function of the peripheral nervous system.

2. The connective-tissue sheath surrounding the funiculus or bundle of nerve-fibers.

Etymology of PERINEURIUM

The word "perineurium" is derived from the combination of two Greek roots: "peri", meaning "around", and "neuron", meaning "nerve". The suffix "-ium" is a noun-forming ending. Therefore, "perineurium" literally means "around the nerve" or "encircling the nerve". It is a term used in anatomy and refers to the protective connective tissue layer that surrounds individual nerve fascicles within a peripheral nerve.

Plural form of PERINEURIUM is PERINEURIA
