Describe the purpose of the cervix during pregnancy. When a woman becomes pregnant, a mucus plug forms in the cervix to act as a barrier, protecting the fetus and keeping the developing fetus in the uterus until full term. Describe the purpose of the cervix prior to ovulation Just prior to ovulation, the cervix swells, softens and secretes mucus allowing sperm better access to and viability within the uterus 1.Seminal Vesicles - Secretes vitamin C, Produces 2.) Prostate gland - Secretes alkaline 3.) Bulbourethral glands testosterone-- Secretes alkaline, first to secrete 4.) Testes prostaglandins-- Produces 5.) Anterior pituitary during ejaculation-- Produces LH Match the gland/organ with the best description(s) A-F. Select all that apply. 1.Seminal Vesicles -- Secretes fructose, Produces prostaglandins 2.) Prostate Gland-- Secretes alkaline fluid 3.) Bulbourethral glands-- First to secrete during ejaculation, Secretes alkaline fluid 4.) Testes-- Produces sperm 5.) Anterior Pituitary-- Produces FSH Name and discuss the purpose of the region of the sperm indicated by the arrow in the figure below. The midpiece of the sperm, houses the mitochondria and is necessary to support movement through the female reproductive track (in addition to the flagellum or tail, that also supports movement.) to contact an ovum. Discuss the developmental steps of how a fertilized egg becomes implanted in the uterus. Includes specific locations, names, and amounts of time in your answer. The zygote travels through the oviducts, where it undergoes multiple mitotic division for 3 through 4 days to become the morula. The morula undergoes additional mitotic division over the next 3 through 4 days to become the blastocyst (these mitotic division happen when the morula is attached in the uterus.) the blastocyst then is implanted in the endometrium of the uterus for the duration of the pregnancy.
