Anatomy of the ProstateNick Shroff2020-09-20T13:37:57-05:00
The healthy human prostate weighs between 10-20 grams. The gland is shaped like an inverted cone and lies between the bladder and pelvic floor. It consists of cells arranged in columns surrounding a lumen (central passageway). This arrangement of cells is termed as prostatic glands.
The glands are surrounded by a lining of smooth muscle tissue and a capsule (fibro elastic stroma) that gives the gland its shape. The glands are arranged with their openings into the prostatic urethra, which is the portion of the urethral tube passing through the prostate.
The smooth muscles contract during ejaculation to empty the prostatic glands of their secretion, and this is the prostatic fluid. Many such glands are present in the prostate, and together they form the whole prostate. The prostate rests on the pelvic floor that has larger muscles. Both the prostatic muscles and the pelvic muscles contract during ejaculation to expel the prostatic fluid.
Why is the prostate important?
The prostate is an organ present in men that is useful for helping men have children. The prostate and seminal vesicles produce most of the fluid during ejaculation, and this fluid is required for nourishing sperm. The prostate is important because two of the most common diseases affecting men occur within the prostate, namely, benign prostatic enlargement and prostate cancer.
The prostate is also located in an area surrounded by essential nerves and muscles. Injury to these muscles and nerves due to prostate disease or treatment can cause impotence and urinary incontinence. It is, therefore, vital to know the following:
