Question 1

________ Herniation of the abdominal viscera

Accepted Answer

Herniation of abdominal viscera into the thorax occurs through a posterolateral defect in the diaphragm where there is failure of development or fusion of the pleuroperitoneal membrane with other parts of the diaphragm,usually on the left side.Because of the presence of abdominal viscera in the thorax,the lungs often are compressed and may be hypoplastic (incompletely developed).

Question 2

________ Future pleural cavity

Accepted Answer

The answer of  ________ Future pleural cavity
...

Question 3

________ Derived from the third to fifth cervical spinal cord segments

Accepted Answer

The phrenic nerves are derived from the third to fifth cervical spinal cord segments and innervate the diaphragm, making them the only option in the list derived from this specific region. The esophageal mesentery, pleuropericardial membrane, crura of the diaphragm, and embryonic mediastinum are not derived from this specific region of the spinal cord.

Question 4

________ Diaphragmatic muscles

Accepted Answer

The diaphragmatic muscles are mainly derived from myoblasts that migrate from the myotome regions of the cervical somites.Other myoblasts are derived from the myotome regions of the thoracic somites,and some myoblasts originate in the body wall tissues.

Question 8

________ Derived from the foregut

Accepted Answer

This question is difficult to answer definitively without additional information, but the image appears to be of an organ or tissue that is derived from the foregut. Choice C, the liver, is a foregut-derived organ that could potentially match the appearance of the image, while the other choices do not match the characteristics of a foregut-derived structure.

Question 9

...

Question 10

________ Forms median part of the diaphragm

Accepted Answer

The dorsal mesentery of the esophagus (mesoesophagus)forms the median part of the diaphragm.The pleuroperitoneal membranes fuse with the esophageal mesentery and septum transversum during the sixth week,forming a partition between the thoracic and abdominal cavities.Completion of the diaphragm occurs during the 9th to 12th weeks as body wall tissue is added to it peripherally.

Question 11

________ Muscular origins of the diaphragm

Accepted Answer

The crura of the diaphragm are the muscular origins of the diaphragm. The diaphragm is a muscle that separates the thoracic cavity from the abdominal cavity and helps in breathing. The crura are two tendinous structures that arise from the vertebral bodies of L1-L3 and run anteriorly to fuse with the central tendon of the diaphragm.

Question 13

________ Ventral mesentery of the stomach

Accepted Answer

The answer of  ________ Ventral mesentery of the stomach
...

Question 14

________ Posterolateral diaphragmatic defect

Accepted Answer

The pleuroperitoneal membrane is a structure that separates the thoracic and abdominal cavities. A posterolateral diaphragmatic defect can occur if there is a congenital defect in this membrane.

Question 15

________ Connects the pericardial and peritoneal cavities

Accepted Answer

The pericardioperitoneal canals become the adult pleural cavities.Membranes develop at the cranial and caudal ends of these canals that separate the pleural cavities from the pericardial cavity and the peritoneal cavity,respectively.The developing lungs invaginate the medial walls of the pericardioperitoneal cavities.The inner (visceral)and outer (parietal)walls of these canals eventually come close together as the layers of pleura.

Question 16

________ Dorsal mesogastrium

Accepted Answer

The answer of  ________ Dorsal mesogastrium

Question 17

________ Esophageal mesentery

Question 18

________ Caudal part of the foregut

Accepted Answer

The answer of  ________ Caudal part of the foregut
...

Question 19

________ Large esophageal opening

Accepted Answer

A congenital hiatal hernia is a condition where there is a protrusion of the stomach through the diaphragmatic opening called the esophageal hiatus. This opening is larger than usual, allowing the stomach to move upwards into the thoracic cavity.
