Explain the collagen continuum used to attach skeletal muscle organs to bones.

Give five distinctive differences between receptive and excitable membranes

Double fractures of at least three or more adjacent ribs, which causes the thoracic cage to become unstable. This the definition of what anatomic alteration?

Postoperative patients benefit from what respiratory modality for good lung expansion?

Atelectasis is an abnormal condition of the lungs characterized by the partial or total collapse of previously expanded alveoli, thus resulting in the prevention of respiratory exchange of carbon dioxide and oxygen in that part of the lung and reduced lung compliance. 

Select the most appropriate representations identified on a chest x-ray in patients with atelectasis:

The pleural space is in direct contact with the atmosphere such that gas can move freely in and out. Which type of pneumothorax does the above statement represent?

Which pulmonary disorders can cause subsequent atelectasis?
