Corpus luteum is:
1. Ruptured Graafian follicle
2. Released ovum surrounded by cells
3. Developing follicle
4. Enzyme-secreting structure in the ovary
The cessation of menstrual cycles is called as:
1. | Menarche | 2. | Thelarche |
3. | Pubarche | 4. | Menopause |
LH surge:
1. | is a dramatic sudden increase in the levels of LH during the early part of menstrual cycle and is responsible for ovulation |
2. | 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 |
4. | 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:
1. | LH | 2. | FSH |
3. | Progesterone | 4. | Estrogen |
Zona pellucida is a membrane surrounding:
1. | Secondary oocyte | 2. | Secondary follicle |
3. | Corona Radiata | 4. | Trophoblast cells |
What ensures that only one sperm can fertilize the ovum?
1. | Corona Radiata | 2. | Ground substance around ovum |
3. | Zona pellucida | 4. | Acrosome |
Fertilization occurs at:
1. Infundibulum of the fallopian tube
2. Ampullary – isthmic junction of the fallopian tube
3. Fundus of the uterus
4. Body of the uterus
In humans, the sex of the baby is determined:
1. | At the time of fertilization and by the father |
2. | At the time of fertilization and by the mother |
3. | At the time of implantation and by the father |

Morula is a solid ball of cells during early embryonic development and consists of:
