Transition zone (TZ) 5% The transition zone surrounds the proximal urethra. [2] ~10–20% of prostate cancers originate in this zone. It is the region of the prostate gland that grows throughout life and causes the disease of benign prostatic enlargement. [6] [7] Anterior fibro-muscular zone (or stroma) —
Seminal fluid continues down the ejaculatory duct into the prostate gland, where an alkaline prostatic fluid is added. [4] This addition provides the texture and odor associated with semen. [ 4 ] The alkalinity of the prostatic fluid serves to neutralize the acidity of the female vaginal tract in order to prolong the survival of sperm in this ...
Benign prostatic hyperplasia (BPH), also called prostate enlargement, is a noncancerous increase in size of the prostate gland. [1] Symptoms may include frequent urination , trouble starting to urinate, weak stream, inability to urinate , or loss of bladder control . [ 1 ]
The prostatic urethra, the widest and most dilatable part of the urethra canal, is about 3 cm long.. It runs almost vertically through the prostate from its base to its apex, lying nearer its anterior than its posterior surface; the form of the canal is spindle-shaped, being wider in the middle than at either extremity, and narrowest below, where it joins the membranous portion.
The urethra (pl.: urethras or urethrae) is the tube that connects the urinary bladder to the urinary meatus, [1] [2] through which placental mammals urinate and ejaculate. [3] In non-mammalian vertebrates, the urethra also transports semen but is separate from the urinary tract.
Transition zone may refer to: Transition zone (Earth), a part of the Earth’s mantle located between the lower mantle and the upper mantle; Transition zone, the region between the near and far fields of a transmitting antenna; Transition zone (TZ), a glandular region of the prostate—see Prostate#Zones; Zone of transition, a zone in urban ...
Prostate cancer is a major topic of ongoing research. From 2016 to 2020, over $1.26 billion was invested in prostate cancer research, representing around 5% of global cancer research funds. [122] This places prostate cancer 10th among 18 common cancer types in funding per cancer death, and 9th in funding per disability-adjusted life year lost ...
The urethral crest is an anatomical feature present in the urinary system of both males and females.. In males, the urethral crest is known as the crista urethralis masculinae, or the crista phallica, and is a longitudinal fold on the posterior wall of the urethra extending from the uvula of the bladder through the prostatic urethra.
