This is an accessible content page containing a Hot Spot Explore Activity. It has opened in a new window.
The activity has an image with defined hotspot areas. The hotspot areas in the image are labeled as:

Bladder--Detrusor muscle contracts via pelvic parasympathetic splanchnics. Sphincter inhibited by sympathetics. Max volume is 500ml. Origin is via endoderm except trigone which is mesodermal. Lined with transitional epithelium.
Seminal vesicle--Secretes 60% of seminal fluid consisting of vitamin C, flavins,fructose, enzymes, prostaglandins, and mucus. Secretions are also alkaline and neutralize the vaginal acidic environment. Contraction by sympathetics. Joins vas to form ejaculatory ducts.
Pubic symphysis-fibrocartilage which loosens during pregnancy. In contact with clitoris in female. non-synovial amphiarthroidal joint
Bladder neck opening into prostatic urethra
Prostate-Walnut sized organ which secretes acid phosphatase and zinc into semen. Secretes 25% of seminal volume. Means "protector" Alkaline secretions neutralize vagina. Secretes prostate specific antigen (PSA) which can be monitored for cancer
Urogenital Diaphragm- consists of urethral sphincter and deep transverse perineal muscle. Sandwiched between the superior and inferior fascia of the ug diaphragm. Known as the" deep pouch" and contains the bulbourethral glands in the male.
Corpora cavernosum-paired cylinders of erectile tissue. Contain 80% of blood in a erection. Termed crura when touching pubic rami. Erection is under parasympathetic control. "point and shoot"
Corpus spongiosum-Erectile tissue which keeps the urethra open during erection. Continuous with the bulb of the penis.
Spongy urethra-- urethra covered by the corpus spongiosum, when damaged during a" straddle injury" urine and blood can leak into scrotum and up abdominal wall.
