which wall of the uterus is made of smooth muscle
Myometrium The myometrium is the middle layer of the uterine wall, consisting mainly of uterine smooth muscle cells (also called uterine myocytes[1]), but also of supporting stromal and vascular tissue.[2] Its main function is to induce uterine contractions.
Urethra In anatomy, the urethra (from Greek οὐρήθρα – ourḗthrā) is a tube in placental mammals that connects the urinary bladder to the urinary meatus for the removal of fluids from the body. In males the urethra travels through the penis, and carries semen as well as urine.[1] In females, the urethra is shorter and emerges at the urinary meatus above the vaginal opening.
