Female urethral anatomy. The urethra is approximately 4 cm long in the female. It is imbedded in the connective tissue supporting the anterior vagina.

Likewise, what is the urethra made up of?

Anatomy & Function of the Urethra The urethra is the tube that passes urine from the bladder out of the body. In women, it is approximately 4 centimeters long. It is composed of smooth muscle fibers, sphincter muscle fibers, a layer of elastic tissue, and collagen tissue and is lined with mucous membrane.

Similarly, is there a sphincter in your urethra? Urethral sphincters. The urethral sphincters are two muscles used to control the exit of urine in the urinary bladder through the urethra. The two muscles are either the male or female external urethral sphincter and the internal urethral sphincter. When either of these muscles contracts, the urethra is sealed shut.

Subsequently, question is, how many layers of tissue are found in the wall of the urethra?

The female urethra is composed of 4 separate tissue layers that keep it closed. The inner mucosal lining keeps the urothelium moist and the urethra supple. The vascular spongy coat produces the mucus important in the mucosal seal mechanism.

What tissue is the male urethra lined with?

The epithelial lining of the male urethra changes from transitional epithelium at the bladder end to pseudostratified epithelium through prostatic, membranous and most of penile urethra, eventually changing to nonkeratinizing stratified squamous epithelium distally.
