It is also referred to the thoracic diaphragm because it’s located in the thoracic cavity, or chest.hen air is drawn into the lungs, the muscles in the diaphragm contract, and pull the central tendon down. This enlarges the chest (thoracic cavity), and air then passes into the lungs to fill the larger space.

Abdominal cavity It is located below (inferior to) the thoracic cavity, and above the pelvic cavity. Its dome-shaped roof is the thoracic diaphragm (a thin sheet of muscle under the lungs), and its oblique floor is the pelvic inlet (the superior opening of the pelvis).he kidneys are located in the abdominal cavity behind the peritoneum, in the retroperitoneum. The viscera are also covered by visceral peritoneum. Between the visceral and parietal peritoneum is the peritoneal cavity, which is a potential space. It contains serous fluid that allows motion.

Thoracic diaphragm Structure [edit]. The diaphragm is a dome-shaped structure of muscle and fibrous tissue that separates the thoracic cavity from the abdomen. The dome curves upwards. The superior surface of the dome forms the floor of the thoracic cavity, and the inferior surface the roof of the abdominal cavity.As a dome, the diaphragm has peripheral attachments to structures that make up the abdominal and chest walls.The muscle fibres from these attachments converge in a central tendon, which forms the crest of the dome.s a dome, the diaphragm has peripheral attachments to structures that make up the abdominal and chest walls.

Thoracic diaphragm The diaphragm separates the thoracic cavity containing the heart and lungs, from the abdominal cavity and performs an important function in respiration: as the diaphragm contracts, the volume of the thoracic cavity increases and air is drawn into the lungs.he diaphragm functions in breathing. During inhalation, the diaphragm contracts and moves in the inferior direction, thus enlarging the volume of the thoracic cavity (the external intercostal muscles also participate in this enlargement).

Diaphragm A diaphragm is a method of birth control used by women. It is a soft, thin, dome-shaped rubber cup with a flexible rim. Spermicidal jelly is placed inside the dome. The diaphragm is placed high in the vagina to hold the spermicide against the cervix. The diaphragm comes in various sizes and must be fitted by a clinician to be effective. The diaphragm acts as a barrier between the opening of the cervix and semen which contains sperm.

The Diaphragm The diaphragm is the primary muscle of respiration. During inspiration, it contracts and flattens, increasing the vertical diameter of the thoracic cavity. This produces lung expansion, and air is drawn in. During expiration, the diaphragm passively relaxes and returns to its original dome shape. This reduces the volume of the thoracic cavity.

Thoracic Diaphragm Facts Diaphragm is a dome shaped structure which has several large muscles which naturally separates any two adjacent parts in a human body or body of the mammals. The thoraco abdominal diaphragm is the commonly known muscle. Considering a human body, these muscles serve to part the cavity of the chest from that of the abdomen. The diaphragm top is located one and one and a half inches from the bottom of the sternum supports the heart, and diaphragm bottom is attached round the lower ribs connecting to the lower lumbar vertebrae.

Diaphragmatic rupture Since the pressure is higher in the abdominal cavity than the chest cavity, rupture of the diaphragm is almost always associated with herniation of abdominal organs into the chest cavity, which is called a traumatic diaphragmatic hernia.

Diaphragm The diaphragm is the dome-shaped muscle that separates the thoracic cavity from the abdominal cavity.he medial margins of the two crura pass forwards and medially. They meet in the midline to form an arch in front of the aorta called the median arcuate ligament. All these mucles insert into the central tendon, a thin but strong aponeurosis. It is situated immediately below and is fused to the pericardium.
