musculus sphincter urethrae
Noun: * A striated sphincter muscle that constricts the urethra: This is a specific, ring-shaped muscle composed of striated (voluntary) muscle fibers. Its primary function is to voluntarily control the flow of urine by constricting (tightening and closing) the urethra, the tube that carries urine from the bladder out of the body.
This term is exclusively used in formal, technical, and academic contexts, specifically within the fields of anatomy, medicine, and physiology. It is not used in everyday conversation. * The musculus sphincter urethrae provides voluntary control over micturition (urination). * Damage to the musculus sphincter urethrae can result in urinary incontinence. * The study focused on the innervation of the musculus sphincter urethrae.
