Sarcolemnous - English Definition & Meaning

Definition

Sarcolemnous refers to something related to or resembling the sarcolemma. The sarcolemma is the membrane surrounding muscle fiber cells. Think of it like the cell membrane, but specifically for muscle cells. It plays a critical role in muscle contraction by receiving and conducting stimuli. A sarcolemnous structure might involve the protective or functional aspects of this membrane. It's a somewhat obscure term, primarily used in detailed anatomical or physiological contexts. Basically, if it relates to the muscle cell's 'skin,' it's sarcolemnous.

Etymology

The word 'sarcolemnous' is derived from 'sarcolemma.' 'Sarco-' comes from the Greek word 'sarx,' meaning 'flesh.' 'Lemma' also comes from Greek, meaning 'husk' or 'rind.' So literally, it refers to the 'flesh's husk,' meaning the outer layer of the muscle fiber. The combination denotes the membrane surrounding muscle tissue.
