Ovaries are the primary sex organs in human females because they:I. Produce the female gameteII. Produce the hormone that regulates the development of secondary sexual characters
FSH:
Acts on Sertoli cells and stimulates secretion of some factors that help in spermiogenesis
Acts on Sertoli cells and inhibits secretion of some factors that help in spermiogenesis
Acts on Leydig cells and stimulates secretion of some factors that help in spermiogenesis
Acts on Leydig cells and inhibits secretion of some factors that help in spermiogenesis
The functions of male sex accessory ducts and glands are maintained by:
Hypothalamic releasing hormone
Pitutary gonadotropins
Adrenal cortex steroids
Testicular androgens
At the birth of the female child, the follicles in her ovaries contain:
Primary oocytes that have been arrested at the S phase of the cell cycle
Primary oocytes that have been arrested at the Prophase I of Meiosis I
Secondary oocytes that have been arrested at the Prophase I of Meiosis I
Secondary oocytes that have been arrested at the Metaphase II of Meiosis II
What is released at ovulation?
Primary oocyte arrested at meiosis I
Primary oocyte arrested at meiosis II
Secondary oocyte arrested at meiosis I
Secondary oocyte arrested at meiosis II
During the follicular phase of the menstrual cycle which of the following occur?I. The primary follicle grows and becomes fully mature Graafian follicleII. The endometrium of the uterus regenerates through proliferation
LH surge:
is a dramatic sudden increase in the levels of LH during the early part of menstrual cycle and is responsible for ovulation.
Is a dramatic sudden decrease in the levels of LH during the early part of menstrual cycle and is responsible for ovulation.
3 is a dramatic sudden decrease in the levels of LH during the mid-menstrual cycle and is responsible for ovulation.
is a dramatic sudden increase in the levels of LH during the mid-menstrual cycle and is responsible for ovulation.
Corpus luteum secretes large amounts of:
LH
FSH
Consider the following two statements:I. Not all copulations lead to fertilization and pregnancyII. Fertilization can occur if the ovum and the sperms are simultaneously transported to the fallopian tubes.
What happens when a sperm enters the cytoplasm of the secondary oocyte?
Release of first polar body
Completion of meiosis II
Degeneration of polar bodies
Dissolution of zona pellucida
In humans, the sex of the baby is determined:
At the time of fertilization and by the father
At the time of fertilization and by the mother
At the time of implantation and by the father
At the time of implantation and by the mother
Cleavage is:
Dissolution of the zona pellucida
A specialized mitotic division in late fetus
A specialized meiotic division in late fetus
A specialized mitotic division in zygote and early embryo
Morula is a solid ball of cells during early embryonic development and consists of:
4 – 8 cells
8 – 16 cells
24 – 30 cells
60 – 72 cells
The fetal body is covered with fine hair, eyelashes separate, and eyelashes are formed by the end of:
20 weeks
24 weeks
28 weeks
30 weeks
The signals of fetal ejection reflex originate from:
Maternal pituitary
Maternal hypothalamus
Fully developed fetus and placenta
Fetal pituitary
To induce uterine contractions for parturition which of the following hormones can be injected to the female?
hCG
What structure gets implanted on the wall on the uterus during embryonic development?
In the given diagram, identify A, B, C and D respectively:
