diafragmei

Diafragmei, also known as diaphragm muscles, are a group of muscles located in the midline of the abdomen, forming a dome-shaped structure that separates the abdominal cavity from the thoracic cavity. The primary function of the diaphragm is to facilitate breathing by contracting and flattening to allow air to enter the lungs during inhalation, and relaxing to allow air to exit the lungs during exhalation. This muscle is innervated by the phrenic nerve, which originates from the cervical spinal cord.

The diaphragm is a critical component of the respiratory system and plays a vital role in maintaining proper lung function and gas exchange. It is composed of two layers of muscle fibers: the inner circular muscle fibers and the outer oblique muscle fibers. The inner fibers contract to flatten the diaphragm, while the outer fibers contract to elevate the diaphragm.

The diaphragm is also involved in other physiological functions, such as coughing, sneezing, and vomiting. It is a unique muscle in that it is the only muscle that separates two cavities within the body. The diaphragm is essential for survival, as it enables the exchange of oxygen and carbon dioxide, which is necessary for cellular respiration.
