Lab 4 Online Assessment

  1. The allantois, identified in the placental cord, is continuous with what anatomical structure?
  2. Identify the 3 vascular shunts, and their location, in the embryonic circulation.
  3. Identify the Group project sub-section that you will be researching. (Add to project page and your individual assessment page)

Lab 1 Assessment

1. Identify the origin of In Vitro Fertilization and the 2010 nobel prize winner associated with this technique.

The technique of In Vitro Fertilisation of (IVF) was developed by a Robert G. Edwards which was awarded the 2010 Nobel prize for this technique of fertilisation. Although the origin and reason for this technique is when all assisted reproduction has failed, the term IVF can be defined as being a process which fertilisation occurs outside the body instead occurs within a testube or petri dish( where the female egg(unfertilised) and male sperm is place together until fertilisation occurs and returned to the uterus (in zygote stage) to continue development as a usual pregnancy(New York Times).

However the origins of IVF was mainly for women unable to give birth, this can be due to damage either in the fallopian tubes or problems with the ovaries which leads to infertility. For these reasons the technique of IVF was developed where the first IVF or test tube baby was born in 1978.

2. Identify a recent paper on fertilisation and describe its key findings.

Paper 1 Outcome of cycles of oocyte in vitro maturation requiring testicular sperm extraction for nonobstructive azoospermia.

Depicted the rates of fertility and of pregnancy cycles of the implantation and transferring of azoospermia. Where not much research is done in this area and though IVM (in vtro maturation) within the research paper being a alternative which has low rates of OHSS (ovarian hyper stimulation syndrome)where results of whether the oocyte rescues the affects sperm by NOA (non obstructive Azoospermia) which relates to perm motility where 4 pregnancies where achieved and 2 were give birth. though its inconclusive that the IVM method increases the chances of pregnancies where sperm affected by NOA, though still has small percent off births as experiment showed 2 births still were achieved

3. Identify 2 congenital anomalies.


which is the hereditary condition which causes bone formation unable to mature and develop properly where bones of limbs become smaller and shorter may also affect the facial region, this si sometimes know as dwarfism

Marfan syndrome:

A condition which affects the connective tissues and causes the limbs to develop this serve disorder can affect more than just limbs reaching to connective tissue through out the body which can cause issues with the heart and the vales.
