The male urethra is comprised of four main segments. The preprostatic urethra runs in front of the prostate, while the prostatic urethra courses through that gland.
The male urethra is an 18-22 cm long muscular tube that conveys urine from the urinary bladder to the exterior via an external opening in the perineum and also functions to provide an exit for semen (sperm) and glandular secretions during ejaculation.
In the anatomy typically called male, there are three parts to the urethra: The prostatic urethra: The part of the urethra that carries seminal fluid through the prostate gland to produce the semen that will be ejaculated. The membranous urethra: The short part of the urethra that transports fluids through the pelvic floor.
According to the latest classification, the male urethra can be divided anatomically into three parts (proximal to distal): Begins as a continuation of the bladder neck and passes through the prostate gland.
The male urethra originates at the bladder neck and terminates at the urethral meatus on the glans penis. It is roughly 15-25 cm long in the adult and forms an "S" curve when viewed from a...
The helpful key to understanding the medical terminology related to a urethral stricture is to have a basic understanding of both the function and anatomy of the male urethra. The primary function of the urethra is to transport urine from the bladder to the tip of the penis, allowing the bladder to empty when urinating.
Your urinary system includes the kidneys, ureters, bladder and urethra. The urinary system removes waste from the body through urine. The kidneys are located toward the back of the upper abdomen. They filter waste and fluid from the blood and produce urine. Urine moves from the kidneys through narrow tubes to the bladder.
The urethra opens externally at the tip of the glans penis as the external urethral orifice (urethral meatus). [Male urethra: Diagram] The female urethra is relatively short, measuring about 4 cm long, a predisposing factor for contracting urinary tract infection.
The male urethra (Fig. 1142) extends from the internal urethral orifice in the urinary bladder to the external urethral orifice at the end of the penis. It presents a double curve in the ordinary relaxed state of the penis (Fig. 1137).
The spongy urethra, also known as the penile urethra, is the longest portion of the male urethra. It extends from the end of the membranous urethra, which passes through the urogenital diaphragm, all the way to the external urethral orifice at the tip of the penis.The spongy urethra is approximately 15–20 cm in length, though this can vary depending on individual anatomy.
