LABORATORY DEFINITIONS
| Question | Answer |
|---|---|
| DEFINE SPERMATOGENESIS? | THIS CELLS PRODUCE SPERMATOZOA(SPERM CELL) THESE MALE GEMETES CONTAIN ONE-HALF THE NORMAL NUMBER(HAPLOID) OF CHROMOSOMES. |
| DEFINE GAMETOGENESIS? | THE DEVELOPMENT AND MATURATION OF SEX CELLS THROUGH MEIOSIS. |
| DEFINE ZYGOTE? | AFTER A FEMAL EGG BECOMES FERTILIZED, IT IS KNOWN AS A ZYGOTE. |
| DEFINE TETRAD? | A four-part structure that forms during the prophase of meiosis and consists of two homologous chromosomes, each composed of two sister chromatids. ... |
| DEFINE OOGENESIS? | The production or development of an ovum IN CONTRAST TO SPERMATOGENESIS. |
| DEFINE UTERINE CYCLE? | The menstrual cycle. |
| DEFINE MENSTRUAL PHASE? | the phase of the menstrual cycle during which the lining of the uterus is shed (the first day of menstrual flow is considered day 1 of the menstrual cycle) |
| DEFINE PROLIFERATIVE PHASE? | the phase of the menstrual cycle after menstruation. Under the influence of follicle-stimulating hormone from the pituitary, the ovary produces increasing amounts of estrogen, causing the lining of the uterus to become dense and richly vascular. |
| DEFINE SECRETORY PHASE? | the second half of the menstrual cycle after ovulation; the corpus luteum secretes progesterone which prepares the endometrium for the implantation of an embryo; if fertilization does not occur then menstrual flow begins |
