The most common type of cardiac septal defect is :
ব্যাখ্যা
Explanation: Membrenous type VSD . Although the most common atrial septal defect is the secondum type ASD, the overall most common cardiac septal defect is the Membrenous type VSD.
১৫.
What causes venous blood to return to the heart?
ব্যাখ্যা
Valves prevent blood in veins from flowing away from the heart, while contracting skeletal muscle compresses the veins and this pushes blood through them towards the heart (as the valves prevent blood from being pushed in the other direction.
১৬.
Which forms an electrical “barrier” between the atria and ventricles so that they contract independently?
ব্যাখ্যা
The fibrous skeleton is a dense framework of collagen within the heart that keeps the orifices of the atrioventricular (AV) valves and semilunar valve patent, provides an attachment site of the valve leaflets and cusps, serves as the origin and insertion sites of cardiac myocytes, and forms an electrical “barrier” between the atria and ventricles so that they contract independently.
১৭.
Which is the embryologic counterpart to the right middle lobe of lung?
ব্যাখ্যা
The left upper lobe contains the cardiac notch, where the left ventricle and pericardial sac lodges. The Lingula (which is the embryologic counterpart to the right middle lobe) lies just beneath the cardiac notch.
১৮.
Closure of the foramen primum results from fusion of the :
ব্যাখ্যা
Explanation: The septum primum and the endocardial cushions fuse to close the foramen primum. Subsequently, perforations in the upper part of the septum primum coalesce to form septum secondum. It is this foramen that closes postnatally when the left atrial pressure equals right atrial pressure.
১৯.
Ostium secondum defect :
ব্যাখ্যা
Explanation: An ostium secondum defects is a large opening between the atria that can be caused either by excessive resorption of the septum primum or inadequate development of the septum secondum. Depending on the size of the defect, there can be shunting of blood between the atria.
২০.
Of the following the most closely associated with the portal vein is:
ব্যাখ্যা
Explanation: The portal vein forms when an anastomotic network around the duodenum forms one vessel. This anastomotic network is from the veins of the gut,the vitelline veins.
২১.
The foramen cecum of the adult tongue:
ব্যাখ্যা
Explanation: The foramen cecum on the tongue is the point from which the thyroid gland evaginated and began its journey down into the neck It lies at the apex of the V shape terminal sulcus, which divides the tongue into anterior two-thirds, from the lateral lingual swellings and tuberculum imper and posterior one-third, from the copula.
২২.
In the third week of human embryonic development :
ব্যাখ্যা
Explanation: It is during the third week that the notochordal process and it's associated mesoderm induce the neural plate. The hollow notochordal process eventually becomes the solid notochord, the forerunner of the axial skeleton.
২৩.
Capacitation of the sperm :
ব্যাখ্যা
Explanation: Capacitation involves removing the glycoprotein coat and seminal plasma proteins from the head of the sperm, exposing the acrosome and allowing the acrosome reaction to occur. Capacitation occurs within the female genital tract, and without its occurrence, fertilization could not occur.
