penis

Back 14

is the male copulatory organ.

Front 15

corpora cavernosa

Back 15

i don't know

Front 16

corpus spongiusum

Back 16

contains the spongy urethra and keeps it open during ejaculation.

Front 17

glans penis

Back 17

it is the distal end of the corpus spongiosum and is a slightly enlarged, acorn-shaped region.

Front 18

ovary

Back 18

are the female gonads.

Front 19

corona radiata

Back 19

is the innermost layer of granulosa cells that becomes firmly attached to the zona pellucida and is called the corona radiata.

Front 20

corpus luteum

Back 20

produces progesterone, estrogens, relaxin, and inhibin until it degenerates into fibrous scar tissue called the corpul albicans.

Front 21

broad ligament

Back 21

encloses the ovaries and attaches them to the pelvic wall where it continues as the parietal peritoneum.

Front 22

ovarian ligament

Back 22

anchors the ovaries to the uterus.

Front 23

syspensory ligament

Back 23

attaches the ovaries laterally to the pelvic wall.

Front 24

fimbruae

Back 24

are finger-like progections of the uterine tubes.

Front 25

uterus

Back 25

i don't know.

Front 26

myometrium

Back 26

consists of three layers of smooth muscle fibers and forms the bulk of the uterine wall.

Front 27

endometrium

Back 27

is a connective tissue.

Front 28

vagina

Back 28

is the receptable for the penis, the outlet for menstrual flow, and the passageway for childbirth.

Front 29

labia majora

mammary gland

Back 34

is the gland that produces milk.

Front 35

sperm cell's head

Back 35

it contains a nucleus with 23 highly condensed chromosomes.

Front 36

sperm cell's acrosome

Back 36

it covers the anterior 2/3 of the nucleus. it is a cap-like vesicle filled with enzymes that help a sperm penetrate a secondary oocyte to bring about fertilization.

Front 37

sperm cell's middle piece

Back 37

it contains mitochondria arranged in a spiral, which provide the energy (ATP) for locomotion of the sperm to the secondary oocyte and for sperm metabolism.

Front 38

sperm cell's tail

Back 38

the tail pushes the sperm cell onward.

Front 39

afterbirth

Back 39

it is the placenta detached from the uterus.

Front 40

umbilical cord

Back 40
