Male Genitalia Flashcards
The shaft of the penis is composed of three cylindrical masses of vascular erectile tissue that are bound together by fibrous tissue
two corpora cavernosa on the dorsal side and the corpus spongiosum on the ventral side.
extends distally to form the acorn-shaped glans.
corpus spongiosum
Center of corpus spongiosum
urethra
Fold of foreskin that extends ventrally from the urethral meatus
frenulum
Thin-walled sac that is suspended below the pubic bone,posterior to the penis.
Scrotum
the muscle contracts when too cold, raising the scrotum and testes upward toward the body for warmth.
cremasteric reflex
Testes are pair of
ovoid-shaped organs
Each testis is covered by a serous membrane.
Tunica vaginalis
Function of testes
produce spermatozoa and male sex hormone testosterone.
The testes are suspended in the scrotum by a
spermatic cord
protrusion of loops of bowel theough weak areas of the musculature.
Hernia
is contained between the anterior superioriliac spine laterally and the symphysis pubis medially.
The inguinal area
Running diagonally between these two landmarks, just above and parallel with the inguinal ligament, is the
inguinal canal
another potential spot for hernia.
Femoral canal
final segment of the digestive system.
Anal canal
Anorectal junction or
pectinate line,mucocutaneous junction, or dentate line.
can distinguish from the perianal skin by its hairless, moist appearance.
Anal opening(or anal verge)
composed of skeletal muscle and is under voluntary control.
External sphincter
composed of smooth muscle and is under involuntary control by the autonomic nervous system.
Internal sphincter
Anal canal proceeds upward toward the umbilicus. Just above the internal sphincter, the dividing point of the anal canal rectum.
Anorectal Junction
rectum is lined with folds of mucosa
Columns of morgagni
The folds contain a network of arteries, veins, and visceral nerves. Between the columns are recessed areas known as .
crypts
lowest portion of the large intestine and is approximately 12cm long, extending from the end of sigmoid column to the anorectal junction.
Rectum
The inside of the rectum contains 3 inward foldings called the _____. The lowest valve may be felt on client’s _____
valve of Houston, left side.
lines the upper two thirds of the anterior rectum and dips down enough so that it may be palpated where it forms the rectovesical pouch in men and the rectouterine pouch in women.
The peritoneum
enlargement of the prostate gland, has become increasingly common in men over age 40.
Prostatic hyperplasia,
Located on either side of and above the prostate gland. These are rabbit-ear-shaped structures that produce the ejaculate that nourishes and protects sperms. They are not normally palpable.
Seminal Vesicles
are mucus-producing, pea-sized organs located posterior 10 the prostate gland. These glands surround and empty into the urethra. They are not normally palpable either.
The Couper (or bulbourethral) glands
Perineal itching is seen with
crab lice(pediculosis pubis)
blood in urine
Hematuria
sexual desire
Libido
Pain with ejaculation may indicate .
epididymitis
-fats in stool.
Steatorrhea
Acute HIV infection-
2-4 weeks
If an examination of the upper rectum and sigmoid colon is necessary, a _______ should be performed.
sigmoidoscopy
Equipment assessing male genitalia
• Stool
• Gown
• Disposable nonlatex gloves
• Flashlight (for possible transillumination)
• Stethoscope (for possible auscultation)
• Water-soluble lubricant
• Specimen card
Lice or nit (eggs) infestation at the base of the
penis of pubic hair is known as .
pediculosis pubis or crabs
A tight foreskin that cannot be retracted is called .
phimosis
A foreskin that, once retracted, cannot be returned to cover the glans is called .
paraphimosis
is displacement of the urinary meatus to the ventral surface of the penis.
Hypospadias
is displacement of the urinary meatus to the dorsal surface of the penis.
Epispadias
Absence of a testis suggests (an undescended testicle).
cryptorchidism
A peritoneal protrusion into the rectum, called a .
rectal shelf
A swollen, tender prostate may indicate .
acute prostatitis
Stool is normally
semisolid, brown, and free from blood.
