Tracheomalacia may involve hypotonia of the trachealis muscle. [6]The trachealis muscle may become stiffer during ageing, which makes the whole trachea less elastic. [7]In infants, the insertion of an oesophagogastroduodenoscope into the oesophagus may compress the trachealis muscle, and narrow the trachea. [8]
The trachealis muscle connects the ends of the incomplete rings and runs along the back wall of the trachea. [3] Also adventitia, which is the outermost layer of connective tissue that surrounds the hyaline cartilage, contributes to the trachea's ability to bend and stretch with movement. [4]

Tracheomalacia occurs when the walls of the trachea collapse. This can happen because the walls of the windpipe are weak, or it can happen because something is pressing on it. This may include hypotonia of the trachealis muscle. [3] The whole windpipe can be affected, or only a short piece of it.
The glottis closes (muscles innervated by recurrent laryngeal nerve) and the vocal cords contract to shut the larynx. The abdominal muscles contract to accentuate the action of the relaxing diaphragm; simultaneously, the other expiratory muscles contract. These actions increase the pressure of air within the lungs.
People need to consume enough protein in their diets to maintain proper body function. Common protein sources include nuts, meat, and eggs. Common protein sources include nuts, meat, and eggs.
Maples recovered from the infection but was diminished, her family says. She died Feb. 4, 2012, after choking to death from a mucus obstruction that clogged her airway, an autopsy concluded. Maples' family believes the Vitas’ drug regimen weakened her, and the health crisis she suffered while under the hospice's care damaged her already frail ...

O (Occurrences) Number of times that the named muscle row occurs in a standard human body. Here it may also be denoted when a given muscles only occurs in a male or a female body.
