Exam 2: Anatomy of Respiration

Match each muscle to the correct descriptor. Terms may be used more than once or not at all. -Lies deep to the pectoralis major, originates on the coracoid process of the scapula, and elevates the rib cage

During inspiration, the diaphragm is contracted, which causes it to (elevate/depress) ____________________.

The _________________________ muscles are posterior thoracic muscles of inspiration that elevate the rib cage. Each portion originates on a transverse process of a vertebra (from C7 through T11), for a total of 12 muscles. Fibers course obliquely down and out to insert into the tubercle of the rib below.

Which of the following is defined as the exchange of oxygen between an organism and its environment?

C1 is termed the

Match each muscle to the correct descriptor. Terms may be used more than once or not at all. -Segmented muscle that runs from the xiphoid process to the pubic symphysis

The ____________________ lining completely envelops the lungs and the interior thoracic wall.

The _________________________ muscle originates on the spinous processes of C7 and T1 through T3. Fibers from these muscles course down and laterally to insert just beyond the angles of ribs 2 through 5. This group of muscles elevates the rib cage during inspiration.

Match the indicated muscle or component to the correct function. Terms may be used more than once or not at all. -Pectoralis major

The ____________________ pleurae cover the surface of the lungs.

Match each term to the correct descriptor. Terms may be used more than once or not at all. -The superior-most structure of the sternum

Match each term to the correct descriptor. Terms may be used more than once or not at all. -Muscle of the thorax that elevates the first four ribs

During inspiration, the inspiratory muscles of the rib cage contract, causing the rib cage to (elevate/depress) ____________________.

Which processes form the primary attachment of the rib to the vertebral column?

Match the indicated muscle or component to the correct function. Terms may be used more than once or not at all. -Rhomboideus major and minor

Match each term to the correct descriptor. Terms may be used more than once or not at all. -Forms the superior aspect of the pectoral girdle

Identify the components indicated on the following figure using the letters provided. Letters may be used more than once or not at all. -Posterior-most attachment of the diaphragm

The pectoral girdle consists of the scapula and

Boyle's law states that
