Diaphragm (muscle) (health) and menology (iou)


Diaphragm (muscle) (health)


The muscle that separates the chest (thoracic) cavity from the abdomen. The diaphragm is the main muscle of respiration. Contraction of the diaphragm muscle expands the lungs during inspiration when one is breathing air in. We rely heavily on the diaphragm for our respiratory function so that when the diaphragm is impaired, it can compromise our breathing. The nerve that controls the diaphragm is the phrenic nerve, which originates much high (at C3-C5). During development the diaphragm moves down and drags the phrenic nerve with it.

menology noun. , -iums. E17.
[mod. Latin menologium from ecclesiastical Greek menologion, from men month + LOGOS account.]
An ecclesiastical calendar of the months; spec. a calendar of the Greek Orthodox Church containing biographies of the saints in the order of the dates on which they are commemorated.
