Study Notes
Lung Structure and Thoracic Cage
- The surfaces and fissures of the lung are lined with the pleura.
- The thoracic inlet, also known as the thoracic aperture, is the narrow inlet of the thoracic cage.
- The right lung is divided into three lobes: superior, middle, and inferior.
- The lobes of the right lung are divided by the oblique and horizontal fissures.
Thoracic Cage and Cavity
- The thoracic cage is composed of the sternum, ribs, and thoracic vertebrae.
- The thoracic cavity contains the lung and its pleura on each side.
Lung Anatomy
- The apex of the lung is located approximately 1 inch below the medial third of the clavicle.
Cortisol and Exercise
- Cortisol promotes the breakdown of tissue protein to form glucose during exercise. (True)
- Cortisol does not stimulate the storage of glucose in tissues during exercise. (False)
- Cortisol stimulates the mobilization of free fatty acids from adipose tissue during exercise. (True)
- Cortisol does not inhibit gluconeogenesis in the liver during exercise. (False)
