1. What is the protein that the sperm binds to??? ZP3

2. Name the 3 stages of follicular development??? Primary (primordial), Secondary (antral and preantral) and Preovulatory (Graffian).

Lab 2

1. What factor do the synctiotrophoblast cells secrete to support the ongoing pregnancy??? Secretes hCG to initiate the release of progesterone to maintain the uterine wall.

2. What does the corpus luteum secrete to prevent continuation of the menstrual cycle??? Secretes progesterone to inhibit the menstrual cycle, which is facilitated by hCG which is released by the blastocyst.

3. What are the 2 main tissues to be derived from the germ cell layer continuous with the lining of the amniotic sac??? Ectoderm and endoderm

Lab 3

1. What period of human development (in weeks) do the 23 Carnegie stages cover??? Carnegie stages are used to identify the internal and external developmental process of the embryo. The Carnegie stages are covered over 8 weeks (56 days).

2. What part of the somite will contribute to the vertebral column??? A somite is a segment of mesodermal tissue that gives rise to the vertebral column, dermis, and skeletal muscle. The sclerotome which results from the somites forms the vertebral column.

3. At what Carnegie stage does the human neural tube normally completely close??? At Carnegie stage 13 (4 weeks) the neural tube closes completely.

Lab 4

1. Into what structure do most blood vessels empty before they enter the embryonic heart??? Sinus venosus receives the majority of fluids from blood vessels.

2. What do the dorsal aortas become in the adult??? The descending aorta.

3. What are the layers of cells found in a tertiary villi??? Trophoblasts (consisting of syncitiotrophoblasts & cytotrophoblasts), extraembryonic mesoderm & mesenchyme (which gives rise to blood and placental vessels).

Lab 5

1. What was the question I said in the respiratory lecture would be part of this week's assessment??? There was no actual question posed, however the concept of Congenital Diaphragmatic Hernia was discussed.

2. What is the answer to the above question??? Congenital Diaphragmatic Hernia occurs when the pleuroperitoneal foramen fails to close, the cavity that is formed is known as the Bochdalek. this abnormality results in allowing the viscera to enter into the thorax, subsequently compressing the lungs and impeding its development. This abnormality is more common on the left side than the right.
