Identify the cells that are haploid: (1) spermatogonia (2) primary spermatocytes (3) secondary spermatocytes (4) spermatids (5) spermatozoa
1. | 1, 2, and 3 | 2. | 2, 3, 4, and 5 |
2. | 3, 4, and 5 | 4. | 4 and 5 only |
After leaving the testes, spermatozoa pass sequentially through the :
1. | seminiferous tubule, rete testis, efferent ductule, and epididymis |
2. | epididymis, ductus deferens, seminal vesicle, and ejaculatory duct |
3. | membranous urethra, prostatic urethra, and spongy urethra |
4. | epididymis, ductus deferens, ejaculatory duct, and urethra |
The onset of puberty in males and females is due to the release of:
1. | LH |
2. | FSH |
3. | GnRH |
4. | hCG |
In the ovaries of a girl child, what is basically happening?
1. atresia of primordial follicles
2. completion of meiosis I by primary oocytes
3. formation of antral follicles
4. completion of metaphase II by some oocytes
The most common site of fertilization is:
1. infundibulum
2. ampulla
3. isthmus
4. fimbriae
What are the three tunics of the uterus, from external to internal?
1. endometrium, myometrium, perimetrium
2. perimetrium, myometrium, endometrium
3. stratum basalis, stratum functionalis, endometrium
4. myometrium, stratum basalis, stratum functionalis
In the luteal phase, the secretion of progesterone levels results in:
1. | increased vascularization and development of the uterine glands |
2. | regeneration of endometrium through proliferation. |
3. | sloughing off of the functional layer of the endometrium |
4. | increased secretion of LH and FSH by the anterior pituitary |
In females, estrogen is secreted by:
1. | follicles | 2. | corpus luteum |
3. | placenta | 4. | all of the above |
The menstrual bleed is basically due to the withdrawal of:
1. FSH
2. LH
3. progesterone
4. estrogen
Human chorionic gonadotropin (hCG):
1. stimulates the anterior pituitary to secrete gonadotropins
2. directly maintains the endometrium
3. triggers continued production of progesterone by the corpus luteum
4. stimulates development of the mammary glands
