The Anatomical relations of the Diaphragm Biology Diagrams Della Barnes, an MS Anatomy graduate, blends medical research with accessible writing, simplifying complex anatomy for a better understanding and appreciation of human anatomy. What is the Diaphragm The diaphragm is a large, flat, double-domed sheet of muscle located in the thoracic region of the torso or body trunk. The diaphragm in the thorax is called the thoracic diaphragm and serves as an important anatomical landmark that separates the thorax, or chest, from the abdomen. It functions during breathing when it contracts to enlarge the thoracic cavity and reduce the intrathoracic pressure so that lungs may expand and fill their alveoli with air. It is a dome-shaped muscle and tendon that functions as
Anatomy . The diaphragm is a fibrous muscle that runs between the chest and abdomen, separating these two large cavities. It is asymmetric, as its right dome is larger than the left dome. The diaphragm has openings that allow certain structures to span the chest and abdominal cavities.

The diaphragm is a double-domed musculotendinous sheet, located at the inferior-most aspect of the rib cage. It serves two main functions: Separates the thoracic cavity from the abdominal cavity (the word diaphragm is derived from the Greek 'diáphragma', meaning partition).; Undergoes contraction and relaxation, altering the volume of the thoracic cavity and the lungs, producing The Human Diaphragm The word 'diaphragm' is used to describe several structures in the human body and in particular the thoracic, urogenital and pelvic diaphragms. The most important and largest of these structures is the thoracic diaphragm. It is a flat sheet of muscle that is responsible for breathing. The diaphragm essentially pulls and pushes against the lung causing it to expand with

The diaphragm is a muscular partition that separates the thoracic cavity from the abdominal cavity in the human body. It is an important structure that plays a crucial role in respiration, as it is responsible for generating the negative pressure that helps to draw air into the lungs. Structure Anatomy The diaphragm is a dome-shaped The muscles of the diaphragm arise from the lower part of the sternum (breastbone), the lower six ribs, and the lumbar (loin) vertebrae of the spine and are attached to a central membranous tendon. Contraction of the diaphragm increases the internal height of the thoracic cavity, thus lowering its internal pressure and causing inspiration of air. . Relaxation of the diaphragm and the natural
