|
Describe the structure and muscular content of the scrotum. |
Out-pocketing of the abdominal wall; external location required to reduce temp. for sperm production; Dartos (smooth) and cremaster (skeletal) muscles allow temp control |
|
|
What is contained in the spermatic cord? |
Testicular artery and vein, nerves, lymphatics, and ductus deferens |
|
|
Describe the location and descent of the testes. |
Paired, oval glands; develop in abdominal cavity and descend into scrotum at 7 months (gestation) |
|
|
Describe the internal structure of the testes and the histology of a lobule. |
Covered by tunica albuginea (dense white fibrous C.T.); divided into lobules; each lobule has 1-3 tightly coiled seminferous tubules |
|
|
What is the function(s) of the male duct system? |
Site of final maturation of sperm and storage; as well as transport of sperm |
|
|
What are the components of the male duct system? |
Seminiferous tubules-> Rete testis-> Efferent ductules-> Ductus epididymis (sperm mature here)-> Ductus (vas) deferens-> Ejaculatory duct -> Urethra (prostatic-> Membranous-> Spongy or penile) |
|
|
Describe the location. |
Runs through the abdominal region down to the testes |
|
|
What is the function of male accessory sex glands? |
Secrete bulk of semen |
|
|
Where are the seminal vesicles located? |
Emptying into the ejaculatory duct, posterior to bladder |
|
|
Where is the prostate located? |
At the base of the bladder, surrounds urethra |
|
|
Where is the bulbourethral (Cowper) located? |
Inferior to prostate, embedded in urogenital diaphragm |
|
|
Describe the internal structure of the penis. |
3 cylindrical masses of erectile tissue; they contain numerous blood sinuses which fill and expand during sexual arousal |
|
|
Describe the histology and location of the ovary. |
Firmly attached by ligaments in upper pelvic cavity; cortex contains follicles (ovum + supporting cells) in various stages of development. Supporting cells produce hormones. |
|
|
Compare a primordial follicle to a mature follicle. |
A primordial follicle is the starting point and a mature follicle has passed through all stages of development.
|
|
|
Describe the histology of the uterine tubes. |
Lined with cilia to help move ova or embryo; smooth muscle within the walls that produce peristalsis |
|
|
Describe the attachment of the uterine tubes. |
Not attached directly to ovary; has infundibulum with fimbriae that surrounds (but doesnt touch) the ovary |
|
|
Describe the histology of the uterus. |
3 layers; Outer to inner: Serousal layer (thin cover), myometrium (thick muscle), endometrium (womb lining) |
|
|
Describe the location of the uterus. |
Muscular organ superior to bladder; shaped like "inverted pear" |
|
|
Compare the location of the vagina to the urethra and rectum. |
Posterior to urethra and anterior to rectum |
