Identify the phases of the uterine cycle. (Select all that apply)
Secretory phase
Proliferative phase
Ovulatory phase
Menses
Luteal phase
Correct Answer : A,B,D
A. Secretory phase: The secretory phase is a uterine (endometrial) phase that follows ovulation when the endometrium is prepared for implantation by progesterone-driven secretions
B. Proliferative phase: The proliferative phase is the pre-ovulatory uterine phase in which the endometrium rebuilds under the influence of estrogen.
C. Ovulatory phase: “Ovulatory” refers to ovulation and is classically part of the ovarian cycle (the moment of egg release), not listed as a primary uterine cycle phase.
D. Menses: Menses (menstrual phase) is the shedding of the functional layer of the endometrium and is a primary uterine cycle phase.
E. Luteal phase: The luteal phase is an ovarian cycle phase (post-ovulation, corpus luteum activity). Although it corresponds in time to the uterine secretory phase, “luteal” names the ovarian, not uterine, phase.

Correct Answer is A
Explanation
A. Responsible for uterine contractions: The myometrium is the thick middle layer of uterine smooth muscle and is the contractile layer responsible for rhythmic uterine contractions (e.g., labor, Braxton–Hicks) .
B. Primary support for the uterus: Structural support of the uterus is provided mainly by pelvic ligaments and pelvic floor muscles; this is not the primary role of the myometrium.
C. Thickens in response to estrogen: The endometrium (the mucosal lining) thickens cyclically in response to estrogen; the myometrium undergoes hypertrophy in pregnancy but is not the layer described by cyclic thickening of the uterine lining.
D. Covers the exterior portion of the uterus: The outer covering of the uterus is the perimetrium (serosa), not the myometrium.
Correct Answer is A
