Lab 13
Which of these is sloughed during menses?
endometrium
Name the three layers of the uterine wall from the inside out.
endometrium, myometrium, perimetrium
sperm maturation site
epididymis
fingerlike ends of the uterine tube
fimbriae
glands homologous to the bulbo-urethral glands of males
greater vestibular gland
partially closes the vaginal opening; a membrane
hymen
portion of the urethra that is located in the urogenital diaphragm
intermediate part of the urethra
The interstitial endocrine cells / seminiferous tubules produce testosterone, the hormonal product of the testis.
interstitial endocrine cells
produces oocytes, estrogens, and progesterone
ovary
copulatory organ/penetrating device
penis
loose fold of skin encircling the glans penis
prepuce
location of the testis in adult males
scrotum
Assume a couple has just consummated the sex act and the sperm have been deposited in the vagina. Trace the pathway of the sperm through the female reproductive tract.
(1) vagina (2) cervix (3) uterus (4) uterine tube (5) peritoneal cavity
list the two main functions of the testis
1. produce sperm 2. male sex hormones
An enlarged prostate is associated with a number of disorders, including prostatitis and prostate cancer. Describe the diagnostic exam used to detect an enlarged prostate.
A digital prostate examine is performed by a physician or other mid-level healthcare team member. The examiner gently inserts a finger through the rectum to sense if the prostate is enlarged.
Put the following vestibular-perineal structures in their proper order from the anterior to the posterior aspect: vaginal orifice, anus, external urethral opening, and clitoris.
Anterior limit: (1)clitoris (2) urethral opening (3) vaginal orifice (4) anus
Describe the composition of semen, and name all structures contributing to its formation
Composition of semen: sperm and seminal fluid -> alkaline semen. Structures contributing to the formation of semen: The accessory glands- prostate, seminal glands, and bulbo-urethral glands produce seminal fluid, and the testes produce sperm, which combine to yield semen
What structures compose the spermatic cord?
Connective tissue, ductus deferens, blood vessels, nerves, and lymphatic vessels compose the spermatic cord.
What is an ectopic pregnancy, and how can it happen?
Ectopic pregnancy occurs when a fertilized egg implants in a uterine tube or even on abdominal viscera. It can occur due to infection or inflammation of the fallopian tube or from scar tissue from a previous infection or surgical procedure.
Define ovulation
Ejection of a mature egg from the ovary
egg typically fertilized here
uterine tube
site of fetal development
uterus
copulatory canal
vagina
Of what importance is the fact that seminal fluid is alkaline?
The alkaline nature of semen is importance to buffer against the acidity of the female vagina.
What is the function of the cavernous bodies seen in the penis?
The cavernous bodies function to deliver blood to the penis to make the penis erect and more effective for copulation.
Describe the epithelium found in the uterine tube.
The epithelium around the uterine tube is composed of ciliated secretory epithelium.
Name the structures composing the external genitalia, or vulva, of the female.
The external genitalia (vulva) consists of the mons pubis, the labia majora, the labia minora, the clitoris, the external urethral and vaginal orifices, the hymen, and the greater vestibular glands.
What is the function of the stereocilia exhibited by the epithelial cells of the mucosa of the epididymis?
The function of the stereocilia is to absorb excess fluid and to provide nutrients to the maturing sperm cells.
Where is the spermatic cord located?
The spermatic cord runs through the inguinal ligament to each each teste.
Why are the testes located in the scrotum rather than inside the ventral body cavity?
The testes are located in the scrotum to keep the sperm viable at sub-core temperature (~34 C).
The prostate, seminal glands, and bulbo-urethral glands produce ___, the liquid medium in which sperm leaves the body.
a. seminal fluid
glands that produce milk during lactation
alveoli
pigmented area surrounding the nipple
areola
The endocrine products of the ovaries are estrogen and:
b. progesterone
Using the following terms, trace the pathway of sperm from the testes to the urethra: rete testis, epididymis, seminiferous tubule, ductus deferens.
(1) seminiferous tubule (2) Rete Testis (3) epididymis (4) ductus deferens
accessory gland that secretes fluid to cleanse the urethra prior to ejaculation
bulbo-urethral glands
After sperm are produced, they enter the first part of the duct system, the:
c. epididymis
The labia majora / clitoris are/is homologous to the penis.
clitoris
becomes erect during sexual excitement
clitoris
muscular passageway conveying sperm to the ejaculatory duct; in the spermatic cord
ductus (vas) deferens
duct connecting alveoli to the storage chambers
lactiferous duct
enlarged storage chamber for milk
lactiferous sinus
subdivision of mammary lobes that contains alveoli
lobule
Which contracts during childbirth?
myometrium
releases milk to the outside
nipple
accessory gland that secretes the largest contribution to semen
seminal gland
The testis is divided into a number of lobes by connective tissue. Each of these lobes contains one to four ___ which converge to empty sperm into another set of tubules called the ___.
seminiferous tubules; rete testis
distal urethra that transports both sperm and urine
spongy urethra
