List the two principal functions of the testis:
|
The two principal functions of the testis are sperm production and testosterone production.
|
|
|
How might enlargement of the prostate gland interfere with urination or the reproductive ability of the male?
|
The prostate gland encircles the urethra just inferior to the bladder. If the gland is enlarged, it will constrict the urethra.
|
|
|
Why are the testes located in the scrotum?
|
The temperature in the scrotum is slightly lower than body temperature, a requirement for the testes to produce viable sperm.
|
|
|
Describe the composition of semen and name all structures contributing to its formation.
|
Semen is composed of sperm and seminal fluid. The sperm are produced in the testes and the seminal fluid is produced in the prostrate, seminal vesicles, and bulbourethral gland.
|
|
|
Of what importance is the fact that seminal fluid is alkaline?
|
The relative alkalinity of semen helps neutralize the acid environment of the female vagina, protecting the sperm, and enhancing their motility.
|
|
Identify all indicated structures or portions of structures on the diagrammatic view of the male reproductive system below. Some answers may be used more than once.
|
The answers are:
a = seminal vesicle b = ejaculatory duct c = prostate gland d = bulbourethral gland e = seminiferous tubule f = testis g = urinary bladder h = ductus deferens i = spongy urethra j = erectile tissue k = shaft of penis l = erectile tissue m = glans penis n = epididymis |
|
|
Match the terms in column B to the descriptive statements in column A.
Column A 1. copulatory organ/penetrating device 2. produces sperm 3. duct conveying sperm to the ejaculatory duct; in the spermatic cord 4. a urine and semen conduit 5. sperm maturation site 6. location of the testis in adult males 7. hoods the glans penis 8. portion of the urethra between the prostate gland and the penis 9. empties a secretion into the prostatic urethra 10. empties a secretion into the membranous urethra |
Column B:
The answers are: 1. = penis 2. = testis 3. = vas deferens 4. = penile urethra 5. = epididymis 6. = scrotum 7. = prepuce 8. = membranous urethra 9. = prostate gland 10. = bulbourethral gland |
|
|
Using the following terms, trace the pathway of sperm from the testes to the urethra:
rete testis, epididymis, seminiferous tubule, ductus deferens ____(1)____ ® ____(2)____ ® ____(3)____ ® ____(4)____ |
The correct answers are:
1. = seminiferous tubule 2. = rete testis 3. = epididymis 4. = ductus deferens |
|
On the diagram of a frontal section of a portion of the female reproductive system seen on the following page, identify all indicated structures. Some answers may be used more than once.
|
The answers are:
= suspensory ligament = fimbriae = broad ligament = ovary = fallopian tube = ovarian ligament = fundus of uterus = body of uterus = endometrium = myometrium = cervix = vagina |
|
|
Identify the female reproductive system structures described below: Use each answer only once.
1. site of fetal development 2. copulatory canal 3. “fertilized egg” typically formed here 4. becomes erectile during sexual excitement 5. duct extending superolaterally from the uterus 6. produces eggs, estrogens, and progesterone 7. fingerlike ends of the uterine tube |
The answers are:
1. = uterus 2. = vagina 3. = fallopian tube 4. = clitoris 5. = fallopian tubes 6. = ovary 7. = fimbriae |
|
|
Using the following terms, put the following vestibular-perineal structures in their proper order from the anterior to the posterior aspect:
vaginal orifice, anus, urethral opening, and clitoris Anterior limit: ____(1)____ ® ____(2)____ ® ____(3)____ ® ____(4)____ |
The correct answers are:
1. = clitoris 2. = urethral opening 3. = vaginal orifice 4. = anus |
|
|
Name the male structure that is homologous to the female structures named below.
labia majora = clitoris = |
The answers are:
a. = scrotum b. = penis |
|
|
Do any sperm enter the pelvic cavity of the female; Why or why not?
|
Sperm may possibly enter the pelvic cavity of the female because there is no actual contact between the female gonad (ovary) and the uterine tube.
|
|
|
Name the structures composing the external genitals, or vulva, of the female.
|
The external genitals consist of the mons pubis, the labia majora and minora, the clitoris, the urethral and vaginal orifices, and greater vestibular glands.
|
|
|
Assume a couple has just consummated the sex act and the male’s sperm have been deposited in the woman’s vagina. Trace the pathway of the sperm through the female reproductive tract.
|
The sperm would travel from the vagina to the cervix to the uterus to the fallopian (uterine) tube.
|
|
|
Define ovulation:
|
Ovulation is the ejection of a mature egg from the ovary.
|
|
|
The testis is divided into a number of lobes by connective tissue. Each of these lobes contains one to four highly coiled, ____(1)____ which converge on a tubular region of the testis called the ____(2)____at the mediastinum of the testis.
|
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 on a tubular region of the testis called the rete testis at the mediastinum of the testis.
|
|
On the diagram showing the sagittal section of the human testis, correctly identify all structures provided with leader lines. Answers may be used more than once.
|
The correct answers are:
a = spermatic cord b = blood vessels and nerves c = ductus deferens or vas deferens d = lobules e = seminiferous tubule f = epididymis g = rete testis h = scrotum i = tunica albuginea |
|
|
Use the key to identify the cell type you would expect to find in the following structures. Use each answer only once.
1. forming part of the primary follicle in the ovary 2. in the uterine tube before fertilization 3. in the mature vesicular follicle of the ovary 4. in the uterine tube shortly after sperm penetration |
The answers are:
1. = oogonium 2. = primary oocyte 3. = secondary oocyte 4. = ovum |
|
|
What is the function of the spongy erectile bodies seen in the male penis?
|
The spongy erectile bodies fill with blood during sexual excitement, causing the penis to enlarge and become rigid.
|
|
|
The female gametes develop in structures called follicles. What is a follicle; How are primary and vesicular follicles anatomically different; What is a corpus luteum:
|
Follicles are saclike structures within which the female gametes begin their development. The primary follicle has one or a few layers of cuboidal follicle cells surrounding a larger central developing ovum, whereas the vestibular follicle is surrounded by a capsule of several layers of follicle cells called the corona radiata. The corpus luteum is a solid glandular structure or a structure containing a scalloped lumen that develops from the ovulated follicle.
|
|
|
What hormone is produced by the vesicular follicle;
By the corpus luteum: |
The vestibular follicle produces estrogens and the corpus luteum produces estrogens and progesterone.
