erythrocytic phase  that phase in the life cycle of a malarial plasmodium in which the parasites multiply in the red blood cells.

five phases  in traditional Chinese medicine, a set of dynamic relations (designated earth, metal, water, wood, and fire) that can be used to categorize relationships among phenomena.

follicular phase  the first half of the human menstrual cycle, lasting from cessation of menstrual flow to the surge of luteinizing and follicle-stimulating hormones at the start of the ovulatory phase.

G1 phase  a part of the cell cycle during interphase, lasting from the end of cell division (the M phase) until the start of DNA synthesis (the S phase).

G2 phase  a relatively quiescent part of the cell cycle during interphase, lasting from the end of DNA synthesis (the S phase) until the start of cell division (the M phase).

luteal phase  the third phase of the human menstrual cycle, beginning with ovulation and ending, in the absence of fertilization, with the menstrual phase.

M phase  the part of the cell cycle during which mitosis occurs; subdivided into prophase, metaphase, anaphase, and telophase.

menstrual phase  the fourth phase of the human menstrual cycle, following the luteal phase in the absence of fertilization. The corpus luteum regresses and is shed through menstruation and growth begins for the ovarian follicle, leading to the next follicular phase.

ovulatory phase  the second phase of the human menstrual cycle, encompassing the surges of luteinizing and follicle-stimulating hormones, and ovulation; it is followed by the luteal phase.

S phase  a part of the cell cycle, near the end of interphase, during which DNA is synthesized; between the G1 and G2 phases.

follicular phase

n.

The phase during which the ovarian follicle develops during the menstrual cycle.

follicular phase,

the long phase constituting the first half of the human menstrual cycle. As the menstrual flow ceases, the ovarian follicle continues its development started at the end of the previous cycle and increases its production of inhibin B and estradiol. The endometrium is stimulated by increasing levels of estrogen and increases in thickness to prepare for possible reproduction. At the end of this phase the luteinizing hormone surge and follicle-stimulating hormone surge begin, signaling the start of the ovulatory phase.
