List the two principal functions of the testis
1) To produce sperm 2)To produce testosterone
Copulatory organ/ penetrating device
Penis
Muscular passageway conveying sperm to the ejaculatory duct; in the spermatic cord.
Ductus (Vas) Deferens
Distal urethra that transports both sperm and urine.
Spongy Urethra
Sperm maturation site.
Epididymis
Location of testis in adult males.
Scrotum
Loose fold of skin encircling the glans penis.
Prepuce
Portion of the urethra that is located in the urogenital diaphragm.
Intermediate part of the urethra
Empties a secretion into the prostatic urethra.
Prostate
Empties a secretion into the intermediate part of the urethra.
Bulbo-urethral glands
<p>Of what importance is the fact that seminal fluid is alkaline?</p>
<p>Seminal fluid is alkaline, which buffers the sperm against the acidity of the female vagina.</p>
Which structures compose the spermatic cord? (5)
The ductus (vas) deferens, blood vessels, nerves, lymph vessels, and connective tissue sheaths compose the spermatic cord.
Trace the pathway of sperm from the testes to the urethra.
Seminiferous tubule-> rete testis-> epididymis-> Ductus deferens.
<p>Name the structures composing the external genitalia, or vulva, of the female. (8)</p>
<p>The external genitalia (vulva) consists of the
1. mons pubis
2. labia majora
3. labia minora
4. clitoris
5. external urethral orifice
6. vaginal orifice
7. hymen
8. greater vestibular glands</p>
Site of fetal development
Uterus
Copulatory canal
Vagina
Egg typically fertilized here
Uterine (fallopian) tube
<p>Becomes erect during sexual excitement (female)</p>
<p>Clitoris</p>
Duct extending from ovaries to the uterus
Uterine (fallopian) tube
Partially closes the vaginal opening; a membrane
Hymen
Produces oocytes, estrogen’s, and progesterone
Ovaries
Fingerlike ends of the uterine tube
Fimbriae
Trace the pathway of the sperm through the female reproductive tract.
It enters the vagina-> then into the cervix-> then into the uterus-> then into the uterine tube-> and into the peritoneal cavity.
The testis is divided into a number of lobes by connective tissue. Each of these lobes contains one to four…
highly coiled seminiferous tubules, which converge to empty sperm into another set of tubules called the rete testis.
What is the function of the cavernous bodies seen in the penis?
This tissue can become engorged with blood, thus making the penis stiff and more effective as a penetrating device.
Name the 3 layers of the uterine wall from the inside out
Endometrium->myometrium->perimetrium
Describe the epithelium found in the uterine tube.
A ciliated secretory epithelium lines the uterine tube.
hematuria / symptomatic of:
abnormal presence of blood in the urine; symptomatic of many disorders of the genitourinary system and renal diseases
refractometer
used in the urinalysis physical examination to measure the urine specimen's specific gravity
instrument that measures the relative index of a substance or solution;three processes involved in formation of urine
filtration, secretion, reabsorption
patient with diabetes will normally have excess in urine
