Male Flashcards
(82 cards)
The penis is comprised of 3…..?
cylindric columns or erectile tissue- the
(1) corpus cavernosa on dorsal side
(2) corpus sponginosum on ventral
(3) corpus sponginosum expands into the Glans (cone of erectile tissue) on distal end
What is the shoulder where the glans joins the shaft?
corona
Frenulum
fold of foreskin extending from urethral meatus ventrally
scrotum
- loose protective sac
- continuation of abdominal wall
- deeply pigmented after adolescence
- large sebaceous follicles
- scrotal wall contains rugae
Cremaster muscle
- in scrotal wall
- ## controls size of scrotum by responding to temp in order to keep testes at 3 degrees below abdominal temp for producing sperm
testis
each half of the scrotum
- produce sperm
- solid oval shape
- compressed laterally
- 4-5 cm long and 3cm wide in adult
- suspended vertically by spermatic cord
- Left is lower than riht because L spermatic cord is longer
epididymis
- cap testis
- coiled ducts that are main storage of sperm
- curved over posterior surface of testis (occasionally in small percent is on anterior of testes)
Vas deferens
lower part of epididymis
- forms spermatic cord
Where do the lymphatics of the penis and scrotal surface drain?
- drain to inguinal lymph nodes
* (the lymphatics of the testes drain into the abdomen)
inguinal area
juncture of lower abdominal wall and thigh
- diagnonal borders are the anterior superior iliac spine and the symphysis pubis
- in between those is inguinal ligament
inguinal canal
narrow tunnel passing obliquely between layers of abdominal muscle
- 4-6 cm long in adult
femoral canal
inferior to inguinal ligament
- medial and parallel with femoral artery
Tanners sexual Maturity Ratings (SMR)- stage 1
- Pubic hair: no pubic hair, fine body hair on abdomen continues over pubic area
- Penis: preadolescent, size and proportion the same as during childhood
- Scrotum: Preadolescent, size and proportion the same as during childhood
SMR- stage 2
- Pubic hair: few straight, slightly darker hairs at base of penis, hair is long and downy
- Penis: little or no enlargement
- Scrotum: testes and scrotum begin to enlarge, scrotal skin reddens and changes in texture
SMR- Stage 3
- Pubilc hair- sparse growth over entire pubis, hair is darker, coarser, and curly
- Penis: begins to enlarge, especially in length
- Scrotum: further enlarged
SMR- stage 4
- Pubic Hair: thick growth over pubic area but not on thighs, hair coarse and curly as in adult
- Penis: penis grows in length and diameter, with development of glans
- Scrotum: testes almost fully grown, scrotum darker
SMR- stage 5
- Pubic Hair: Growth spread over medial thighs, although not yet upward toward umbilicus
- Penis: adult size and shape
- Scrotum: adult size and shape
onset of puberty for boys
- Puberty begins sometime between the ages of 9.5 and 13.5 years. The first sign is enlargement of the testes. Next, pubic hair appears, and then penis size increases.
- The complete change in development from a preadolescent to an adult takes around 3 years, although the normal range is 2 to 5 years
subjective: frequency, urgency, oliguria?
- Frequency= “Are you urinating more than usual?”
Rationale:
Frequency. Average adult voids 5-6 ×/day, varying with fluid intake, individual habits.
Polyuria—excessive quantity.
Oliguria—diminished quantity, <400mL/24 hours.
- Urgency= do you feel as though you cant wait?
- Nocturia occurs together with frequency and urgency in urinary tract disorders. Other origins: cardiovascular, habitual, diuretic medication.
Dysuria
- Any pain or burning with urinating?
Dysuria. Burning is common with acute cystitis, prostatitis, urethritis.
Subjective: Hesitancy or straining?
Hesitancy and straining= Ask
“Any trouble starting the urine stream?”
•Need to strain to start or maintain stream? (straining)
•Any change in force of stream: narrowing, becoming weaker? (Loss of force and decreased caliber)
•Dribbling, such that you must stand closer to the toilet? (terminal dribbling)
•Afterward, do you still feel you need to urinate? (sense of residual urine)
•Ever had any urinary tract infections?(recurrent acute cystitis)
*These symptoms suggest progressive prostatic obstruction.
Subjective: urine color
Is the usual urine clear or discolored, cloudy, foul-smelling, bloody
Cloudy in urinary tract infection.
Hematuria—a danger sign that warrants further workup.
Subjective: past genitourinary history
(1) Any difficulty controlling your urine?
Urge incontinence—involuntary urine loss from overactive detrusor muscle in bladder. It contracts, causing urgent need to void.
(2) Accidentally urinate when you sneeze, laugh, cough, or bear down?
Stress incontinence—involuntary urine loss with physical strain, sneezing, or coughing due to weakness of pelvis floor.
(3) Any history of kidney disease, kidney stones, flank pain, urinary tract infections, prostate trouble?
Subjective: Penis
Any problem with penis—pain, lesions?
• Any discharge? How much? Has that increased or decreased since start?
*discharge occurs with infection
• The color? Any odor? Discharge associated with pain or with urination?
