7
Q

what is the vas deferens?

A

18 inch tube that runs from testes to the prostate gland, travels within spermatic cord, winds around bladder and merges with the duct from the seminal vesicle to form the ejaculatory duct

8
Q

what is the function of the accessory glands?

A

produce a nutritious, alkaline fluid for the sperm

9
Q

what are the seminal vesicles?

A

each lies on the posterior wall of the bladder, each merges with the vas deferens to form the ejaculatory ducts

10
Q

what are the accessory glands?

A

seminal vesicles, prostate glands, and bulbourethral glands

11
Q

what is the prostate gland?

A

single chestnut shaped organ, inferior to bladder, contains the first part of the urethra

12
Q

what is the internal anatomy of the ovary?

A

the cortex contains ovarian follicles and the medulla contains the blood vessels

12
Q

what is the bulbourethral gland?

A

each gland is pea shaped and lies within the urogenital diaphragm

13
Q

what is the function of the ovary?

A

to produce oocytes and sex hormones estrogen and progesterone

14
Q

what is the function of the uterus?

A

site for implantation of a fertilized oocyte, site for development of soon to become an embryo

14
Q

what are the fallopian tubes and their functions?

A

each tube is close to the ovary but not attached and at the ends of each tube contain fimbriae, picks up secondary oocytes and transports to the uterus, site for fertilization of the secondary oocyte

15
Q

what is menstruation?

A

when a fertilized oocyte doesn’t implant

16
Q

what is the perimetrium?

A

outermost layer of uterus contains visceral peritoneum and areolar connective tissue

17
Q

what is the myometrium?

A

middle layer, thickest layer, 3 layers of smooth muscle tissue

17
Q

what is the basal layer?

A

deeper layer adjected to the myometrium, permanent layer

18
Q

what is the endometrium?

A

innermost layer, highly vascular, columnar epithelium and connective tissue, fertilized oocyte implants here subdivided into 2 layers

19
Q

what is the functional layer?

A

it will grow and develop during the ovulation cycle and if its fertilized oocyte doesn’t implant the layer is shed during menstruation

19
Q

what is the vagina and function?

A

lies behind bladder and infront of rectum, copulatory organ, passageway for menstruation and fetus
