Q

Stratum functionalis of endometrium

A

discharged during menstruation; site of implantation of blastocyst

21
Q

Stratum basalis of endometrium

A

reforms stratum functionalis after menstruation

22
Q

Myometrium

A

contracts during childbirth

23
Q

Vagina

A

receives penis during sexual intercourse; allows menses to exit the uterus; passageway for childbirth

24
Q

Lobules

A

contain glandular alveoli that function to produce milk during lactation

25
Q

Lactiferous ducts

A

drain milk from the glandular alveoli to the lactiferous sinuses

26
Q

Lactiferous sinuses

A

collect milk during nursing

27
Q

supports the uterus and vagina

28
Q

Ovarian ligament

A

anchors the ovary medially to the uterus

immature sperm cell with a haploid number of chromosomes (23 chromosomes) that results at the end of meiosis

33
Q

Oogonium

A

stem cell with a diploid number of chromosomes (46 chromosomes) that will undergo meiosis to form ootids

34
Q

Ootid

A

immature ovum with a haploid number of chromosomes (23 chromosomes) that results at the end of meiosis
