-
This organ serves as a temporary reservoir for urine, is located immediately posterior to the pubic symphysis in both genders.
The urinary bladder
-
In females, the bladder is also immediately (position)
anterior to the uterus.
-
The bladder is very flexible, capable of holding as much as
750 ml of urine.
-
The four surfaces of the bladder are:
•Superior – body of the bladder •Posterior – fundus or base of the bladder •Inferolateral (2) – adjacent to levatorani muscles
-
The four angles of the bladder are:
•Anterior – bladder apex; formed by junction of superior and inferolateral surfaces •Inferior – bladder neck; formed by junction of posterior and inferolateral surfaces •Posterolateral (2) – site of ureter entrances
-
The distal portion of the large intestine is
the rectum
-
Measuring about ? in length
15 cm
-
the rectum begins at the
end of the sigmoid portion
-
the rectum ends at the
anal canal
-
The anatomical features of the rectum are the:
- •Sacral flexure – proximal curve
- •Perineal flexure – distal curve
- •Ampulla – upper, expandable one-third of rectum
- •Transverse rectal fold (Kohlrausch's fold) – located between the flexures about 5-8 cm from the anus
- •Anal columns – longitudinal folds in the distal rectum
-
The female reproductive organs are the:
- •Uterus
- •Ovaries
- •Uterine tubes
- •Vagina
-
UTERUS:
- •Pear-shaped, muscular organ
- •Located between the bladder and rectum
-
•The Uterus is Divided into body (proximal portion) and cervix (distal portion)
- •Fundus – upper, rounded portion of body
- •Cornua – corners of body where uterine tubes connect
-
•Uterus Three tissue layers:
- ◦Endometrium – innermost layer
- ◦Myometrium – thickest, middle layer of muscle
- ◦Perimetrium – outer, serous layer
-
•Uterus Function is to:
house and protect fetus during pregnancy
-
•Supported by ligaments
- ◦Round ligaments
- ■Extend from cornua to labia majora
-
◦Uterosacral ligaments
■Connect lateral walls of cervix to sacrum
-
◦Lateral cervical ligaments
■Fan-shaped ligaments from lateral walls of cervix and vagina to lesser pelvis
-
Vesicouterine pouch
- •Anterior space
- •Located between uterus and bladder
-
Rectouterine pouch (pouch of Douglas)
- •Posterior space
- •Located between uterus and rectum
-
Retropubic space
- •Inferior space
- •Located between bladder and pubic bones
-
The primary organs of the male reproductive system are the:
- •Testis
- •Epididymis
- •Vas deferens
- •Ejaculatory duct
- •Seminal vesicle
- •Prostate gland
- •Bulbourethral gland
- •Penis
-
Testis
- •Paired, oval organs
- •Suspended in scrotum
- •Comprised of lobules containing seminiferous tubules
- •Function to produce sperm and sex hormones
-
Epididymis
- •3 parts: head, body, tail
- •Receives seminiferous tubules at head
- •Functions to store sperm during maturation
-
Vas deferens
- •Continuation of the tail of the epididymis
- •Contained within spermatic cord
- •Merges with seminal vesicle to form ejaculatory duct
-
Ejaculatory duct
- •Formed by junction of seminal vesicle and vas deferens
- •Empties sperm into the prostatic urethra
-
Seminal vesicle
- •Paired glands consisting of coiled tubules that form pouches
- •Located lateral to vas deferens, posteroinferior to bladder, and superior to the prostate
- •Functions to produce part of seminal fluid before ejaculation
-
Prostate gland
- •Largest accessory gland of male reproductive system
- •Divided into 4 zones:
- ◦Peripheral (70%)
- ◦Central (25%)
- ◦Transition (5%)
- ◦Periurethral (>1%)
- •Surrounds prostatic urethra
- •Located inferior to the bladder
- •Functions to secrete part of seminal fluid
-
Bulbourethral glands
- •Two small glands; also called Cowper’s glands
- •Located posterior and lateral to membranous urethra
- •Function to secrete part of the seminal fluid
-
Penis
- •External reproductive organ
- •2 parts: root (attachment portion) and body (free portion)
- •Composed of 3 tissue masses:
- ◦Corpora cavernosa (2)
- ◦Corpora spongiosum
