APPLIED RADIOLOGICAL ANATOMY

Detailed explanation-1: -Abstract. The tongue is the most common cause of upper airway obstruction, a situation seen most often in patients who are comatose or who have suffered cardiopulmonary arrest. Other common causes of upper airway obstruction include edema of the oropharynx and larynx, trauma, foreign body, and infection.

Detailed explanation-2: -Hypotonia means decreased muscle tone. It can be a condition on its own, called benign congenital hypotonia, or it can be indicative of another problem where there is progressive loss of muscle tone, such as muscular dystrophy or cerebral palsy.

Detailed explanation-3: -General anesthesia affects lung function primarily because of the loss of muscle tone, which promotes a reduction in lung volume, an alteration in ventilation-perfusion ratio and the onset of lung atelectasis.
