PreQual Review exam 2

________ is the braking activity that counteracts the relaxation pressures and promotes the steady lung pressure necessary for phonation

• Exhalatory checking action

• Inspiratory checking action

The _______ nerves originate in the brainstem and terminate in the muscles or organs of the head and neck

• spinal

• cranial

Airway resistance is due mainly to the diameter of the airways. In practical terms, which of the following is true:

• The narrower a tube, the more resistance the tube offers to the airflow

• The wider a tube, the more resistance the tube offers to the airflow.

• The narrower a tube, the less resistance the tube offers to the airflow,

Respiration

• Is the type of breathing during speech production

• refers tot he gas exchange at the cellular level

Distinct upward movement of the shoulders during breathing is called

• Abdominal breathing

• Pectoral breathing

• Clavicular breathing

• Diaphragmatic breathing

The total volume of air that can be exchanged during a single maximal inhalation and exhalation cycle is called

• vital capacity

• respiration

• speech breathing

• tidal volume

Subglottal pressure is the air pressure below the glottis, i.e., the _________

• Velum

• Lungs

• Vocal folds

• Trachea

Which of the following TWO are true about tidal breathing?

• Usually exchanges air amounts equivalent to vital capacity

• usually exchanges air amounts of 38% - 48% of vital capacity.

• Occurs when the body is at rest.

• Is used when we are swimming against a tidal current.

The term motor equivalence refers to

• The phenomenon in which individuals demonstrate different motor behaviors in response to the same stimulus

• The phenomenon in which individuals demonstrate different motor behaviors in response to different stimuli

A motor unit is...

• a nerve

• muscle cell

• the combination of multiple motor neuron branches and the muscles fibers they innervate

• The combination of single motor neuron branch and the muscle fibers innervate
