What happens if the sperm are expelled too soon from the epididymis?

Back 13

they lack the ability to be motile, which is necessary to travel through the female reproductive tract and fertilize an oocyte

Front 14

What happens if sperm are not ejected from the male reproductive system in a timely manner?

Back 14

The old sperm degenerate and are resorbed in the epididymis

Front 15

Where do sperm go after developing in the epididymis?

Back 15

ductus deferens

Sperm enter the ductus deferens after what residing in what structure?

Back 18

edpididymis

Front 19

What structure does the ductus deferens travel within?

Back 19

within the spermal cord

Front 20

Besides the ductus deferens, what else travels within the spermal cord?

Back 20

pampiniform plexus, testicular artery and testicular nerve

Front 21

What is the wall of the ductus deferens composed of?

Back 21

an inner mucosa, a middle muscularis, and an outer adventitia

Front 22

What layer of the wall of the vans deferens contains several layers of smooth muscle that contract to help move sperm cells through the ductus deferens, since sperm do not exhibit motility until they are ejaculated from the penis.

Back 22

muscularis

Front 23

When do sperm exhibit motility?

Back 23

Only after they are ejaculated from the penis

Front 24

what is the outermost wall of the vans deferens?

Back 24

adventitia

Front 25

The ductus deferens travels through the spermatic cord which is originates where?

Back 25

in the inguinal canal

Front 26

What 3 layers make up the spermatic cord?

Back 26

internal spermatic fascia, the cremaster fascia, and the external spermatic fascia

Front 27

What is the inner mucosa of the ductus deferens lined with?

Back 27

ciliated epithelium

Front 28

Where does the ductus deferens travel through and where does it separate from the outer spermatic cord components, and what structure does it extend posteriorly along?

Back 28

The pelvic cavity, the bladder

Front 29

what is the ampulla?

Back 29

the unites with the proximal region of the seminal vesicle to form the terminal portion of the reproductive system, called the ejaculatory duct

Front 30

Where does sperm come from and where does seminal fluid come from?

Back 30

sperm from the ductus deferens
seminal fluid (from the seminal viscle

Front 31

Where does the sperm go after the ejaculatory duct?

Back 31

to the prostatic urethra to membranous urethra to spongy urethra and out

Front 32

What does the urethra do?

Back 32

Transports semen from both ejaculatory ducts to the outside of the body

Front 33

What does the seminal fluid do?

Back 33

alkaline solution that neutralizes the acidity of the vagina.

Front 34

What glands produce the seminal fluid that neutralizes the acidity of the vagina?

Back 34

seminal vesicles

Front 35

where are the seminal vesicles located?

Back 35

in the posterior surface of the urinary bladder adjacent to eh ampulla of the ductus deferens

Front 36

What does the seminal fluid contain?

Back 36

fructose and prostaglandis

Front 37

What promotes widening and slight dilation of the external os fo the cervix, which facilitates sperm entry into the uterus?

Back 37

prostaglandis produced by the seminal vesicles which is part of the seminal fluid
