Which is located at the base of the urinary bladder? A. Seminal vesicle B. Prostate gland C. Bulbourethral gland D. Ovary
Hint: The urinary bladder, or simply the bladder, is a hollow muscular organ in humans and other vertebrates that stores urine from the kidneys before urinating.
Complete Answer: - Typical human bladder may hold between 300 and 500 ml (10.14 and 16.91 fl oz) until the urge to empty occurs, but may hold substantially more.In humans, the bladder is a hollow muscular organ at the base of the pelvis. - In gross anatomy, the bladder can be divided into a broad fundus, a body, an apex, and a spine.There are three holes in the bladder. The two ureters enter the bladder in ureteric orifices, and the urethra joins the trigone of the bladder. - These ureteric openings have mucosal flaps in front of them, which serve as valves to avoid the backflow of urine into the ureters, known as vesicoureteral reflux.The prostate is an accessory gland of the male reproductive system present only in some species. It varies anatomically, chemically and physiologically between organisms. - Anatomically, the prostate is located below the bladder, with the urethra going into the bladder.The seminal vesicle is at the base of the urinary bladder. Seminal vesicles are narrow, long pockets of muscular tissue in the wall between the urinary bladder and the rectum. Sugar fructose is found in the seminal vesicle secretion. Fructose is a type of energy used by sperm. This substance is referred to as semen. Seventy percent of semen is formed by seminal vesicles.
Thus the correct answer is option (A) Seminal vesicle.
Note: The Latin word for "urinary bladder" is vesica urinaria, and the name vesical or prefix vesico-appears in conjunction with related structures such as vesical veins. The modern Latin word for "bladder" – cystitis – appears in similar words such as cystitis (inflammation of the bladder).
