Following birth, an infant patient exhibits breathing difficulty, bluish-colored skin, tachypnea, and tachycardia. The attending pediatric surgeon notes the absence of breath sounds on the left side and, after a chest x-ray. Which structures did not complete its development process?
Since the patient has absence of breath sounds in one side of the chest it is very likely that a Diaphragmatic Hernia has formed. The origins of the Diaphragm are 4, the central tendon that comes from the septum transversum; the Crura that comes that originates in the posterior mesentery of the Esophagus; the pleuroperitoneal membranes and ultimately it gets shaped by in growths of mesenchymal cells from the thoracic wall. The non closure of one of the sides of the Diaphragm would be the direct result of the abnormal development of the pleuroperitoneal membranes.

A 36-year-old female who wants to have children comes to your office for a routine gynecologic examination. She doesn’t have any apparent medical concerns. You instruct her to take a daily folic acid supplement containing 0.4 mg to 0.8 mg to reduce the risks of neural tube defects while she attempts to get pregnant. What event will be prevented if the above mentioned supplement is taken daily?
After the neurulation process the Neural tube is shaped, however, it remains opened at both ends through a Cranial or Anterior Neuropore and a Caudal or Posterior Neuropore. The non closure of either one of these two Neuropores will give rise to Neural tube defects such as Sina Bifida or Holocrania. The daily dose of folic acid will prevent the Non-closure of the neural tube.
When the Oocyte leaves the Ovary it is caught by a structure that will transport it into the uterine cavity, this structure can be divided into?
Without the action of the Infundibulum and its fimbriae, the Fallopian tube would not be able to pick up and direct the oocyte into the Ampulla, If the oocyte does not reach the Ampulla the male sperm would not be able to meet it and create the next stage of human development (Zygote). Once the zygote is developing it must move towards the uterine cavity and go through the Isthmus to finally nest on the endometrium of the fundus of the uterus. Hence, the three major portions of the Fallopian tube are: Infundibulum, Ampulla and Isthmus.
