NURS 5350 Exam Questions And Correct Answers
Meiosis - ANSWER cell division that starts off with a diploid parent cell and and
produces haploid gametes (sperm/ egg)
Gametes - ANSWER oocytes/ sperm
Gametogenesis - ANSWER process of formation and development of gametes
(egg/sperm)
The number of chromosomes is reduced during - ANSWER Meiosis
Number of haploid spermatids are formed from one spermatogonia - ANSWER 4 (23X,
23X, 23Y, 23Y)
Meiosis - ANSWER Process that allows random assortment of maternal and paternal
chromosomes between gametes
During spermatogenesis what happens in a first meiotic division? - ANSWER Primary
spermocyte (46xy) undergoes reduction to form 2 haploid secondary spermocytes (23x,
23y)
During spermatogenesis what happens in a second meiotic division? - ANSWER 4
haploid spermatids are formed which are half the size of secondary spermocytes (23x,
23x, 23y, 23y)
Spermiogenesis - QUESTION Stage during which 4 spermatids are progressively
differentiated into 4 mature sperms (23x, 23x, 23y, 23y)
, Oogenesis - QUESTION series of processes where oogonia are changed into mature
oocytes
All oogenia are changed into primary oocytes (start 1st meiotic division) before. -
QUESTION birth
Ovulation - QUESTION release of oocyte from ovarian follicle
Primary ooctyes are arrested in prophase until - QUESTION at the start of puberty until
menopause (before ovulation)
First meiotic division of oogenesis completes - ANSWER shortly before ovulation
What kind of cells are gametes? - ANSWER Haploid cells
haploid cells - ANSWER cells containing half the number of chromosomes
Nondisjunction - ANSWER when homologous chromosomes fail to separate during
gametogenesis (trisomy or monsomy result)
Luteinizing hormone - ANSWER precipitates ovulation (release of secondary oocyte)
Follicular development - ANSWER ovarian follicle development
location where fertilization normally occurs - ANSWER ampulla of the uterine tube
Stage 1 of Fertilization - ANSWER Passage of sperm through the corona radiata
Stage 2 of Fertilization - ANSWER Penetration of the zona pellucida
