In this electron micrograph, many adjacent mitochondria are visible within the muscle cell. Itâs no coincidence that they are located close to one another â they do that in order to share glucose, amino acids and fatty acids in order to distribute the production of ATP across a coordinately linked network.
Swallowing involves roughly 50 muscles and many nerves, to move food and drink from the mouth into the stomach. Swallowing disorders, also called dysphagia, occur when nerve control or structures involved in the process are disrupted or not functioning properly. Many conditions can cause swallowing problems, among them: 1  Head, neck or chest injury. 2  Cancer of the head, neck, or food tube (esophagus) , or treatment of these cancers.
a swallowing disorder called dysphagia often occurs as a result of stroke dysphagia may occur in up to 65 percent of stroke patients if not identified and managed it can lead to poor nutrition pneumonia and increased disability aspiration inhaling food or drink is a common problem for people with dysphagia it occurs when material a person is swallowing enters their airway and lungs pneumonia may develop normally aspiration would cause a violent cough but a stroke can reduce sensation after a stroke food or liquid could enter the airway lungs without the survivor being aware of it this is called silent aspiration
