FEMALE REPRODUCTIVE SYSTEM: Part 2 Uterine tube and uterus Objectives: female reproductive system Part 1 Ovary and hormonal orchestration • Identify the tissues of the ovary, and distinguish between primordial, primary, secondary, tertiary, and atretic follicles. • Hormonal orchestration Part 2 Uterine tube and uterus • Describe the three layers of the uterine tube and compare the structure in the different regions along its length. • Describe the three layers of the uterus. Understand the morphological changes in the endometrium and myometrium during the normal menstrual cycle and during pregnancy. Part 3 Cervix, mammary gland, and placenta • Compare the structures and functions of the mammary glands at different stages. • Identify the three layers of the cervix and the vagina. • Identify the villi and intervillous space in the placenta. Relate these structures with placental function.
