A

Active muscle contraction occurs
lungs inflate
rib cage moves in a series of movements
diaphragm pulls down (contracts)

82
Q

What happens to the thoracic cavity during inspiration?

A

The space in the thoracic cavity increases and pressure decreases creating a negative pressure. At this point, atmospheric pressure is greater so this positive pressure moves toward the negative pressure and follows the path of least resistance.

Q

During the inhalation phase of breathing, the dimensions of the thoracic cavity increases in _____ _____.

A

three planes

84
Q

What are the three planes of the thoracic cavity that increase during the inhalation phase of breathing?

A
  1. vertical dimension: is increased by the contraction of the dome-shaped diaphragm
  2. transverse dimension (side to side): is increased by raising of the curved ribs.
  3. anterior-posterior dimension is increased by simultaneous forward and upward movement of the sternum.
85
Q

What needs to happen in order for inspiration to occur?

A

Lungs must be expanded

86
Q

What is inspiration?

A

An active process stimulated by muscle contraction

87
Q

Inspiration is an ______ process stimulated by _____ _____.

A

active

muscle contaction

88
Q

What are the first steps to increasing the lung volume?

A

Involves contraction of principal inspiratory muscles - diaphragm and the external intercostal muscles

89
Q

What happens if the diaphragm stops contracting?

A

You stop breathing.

90
Q

What is diaphragm breathing?

A

deep abdominal breathing

91
Q

What is clavicular breathing?

A

shallow breathing from excessive use of accessory muscles

92
Q

What do you use most during quiet breathing?

93
Q

What do you use when you begin forced respiration?

A

Diaphragm and accessory muscles

94
Q

What happens during forced inspiration?

A

Accessory muscles of inspiration are also involved in increasing the size of the thoracic cavity.
Contraction of the sternocleidomastoid elevates the sternum
Contraction of the scalenes elevates the superior ribs

95
Q

What happens when the sternocleidomastoid muscle contracts during forced inspiration?

A

It elevates the sternum

96
Q

What happens when the scalene muscle contracts during forced inspiration?

A

It elevates the superior ribs

97
Q

What muscle elevates the sternum during forced inspiration when contracted?

A

sternocleidomastoid

98
Q

What muscle elevates the superior ribs when contracted during forced inspiration?

99
Q

What is the function of the diaphragm?

A

muscle fibers shorten
100
Q

What is the primary muscle of inspiration?

101
Q

The diaphragm sets as separation between what?

A

102
Q

The diaphragm is shaped like an inverted bowl with its attachments along what structures?

A

rib cage
sternum
vertebral column

103
Q

Where does the force of contraction directs the diaphragm?

A

toward the abdominal viscera

104
Q

The diaphragm is _____ ____ muscle because it moves skeletal structure.

A

striated skeletal

105
Q

The middle portion of the diaphragm is made up of a large leafy aponeurosis called the ______ _______.

106
Q

What is the central tendon?

A

It is a large leafy aponeurosis that makes up the middle portion of the diaphragm.

107
Q

What is aponeurosis?

A

A sheetlike tendon is a connective tissue which functions to attach muscle to bone.

108
Q

Muscle fibers of the diaphragm radiate out from the ______ ______ forming the sternal, costal, and vertebral attachments.

A

central tendon

109
Q

What nerve is the diaphragm innervated by?

110

volume of air exchanged in one cycle of respiration

A

volume of air that can be inhaled after tidal inspiration

ex yawn

155
Q

What is expiratory reserve volume (ERV)?

A

volume of air that can be exhaled after tidal expiration

Residual volume (RV):

A

The amount remaining in the lungs after maximum exhalation

What is vital capacity (VC) or forced vital capacity (FVC)?

A

volume or air that can be inhaled following maximal exhalation
-IRV +ERV+TV=VC

158
Q

What does vital capacity represent?

A

the capacity available for speech

159
Q

What is total lung capacity (TLC)?

A

Sum of inspiratory reserve volume, tidal volume, expiratory reserve volume and residual volume
TLC = IRV +ERV +RV

160
Q

What is air pressure?

A

The force exerted on the walls of a chamber by molecules of air.
P = F/A

161
Q

What kind of air pressure is required to drive the vocal folds?

A

subglottal pressure

162
Q

A

3cm - 5 cm of water

163

Louder speech requires how many cm of water?

A

12 cm of water or 85 dB

166
Q

What are the pressures of the respiratory system?

A
  • atmospheric pressure is used in discussion of respiratory system
  • Intraoral pressure in the oral cavity
  • subglottal pressure below the vocal folds
  • alveolar or lung pressure wihtin the thoracic activity
167
Q

What is the function of the thyroarytenoid muscle?

A

Pull the arytenoid cartilage forward & backward thereby loosening and tightening the vocal folds

168
Q

What is the function of the lateral cricoarytenoid muscle?

A

adducts the arytenoid cartilages to close the glottis (brings vocal folds together)

169
Q

What is the function of the posterior cricoarytenoid muscle?

A

Rotates the arytenoid cartilages laterally (abduct) causing the vocal folds to separate from one another, opening the glottis

170
Q

What is the function of the cricothyroid muscle?

A

It rotates the thyroid cartilage forward around an axis through the cricothyroid joint. The action stretches the vocal fold thereby tensing it (amount of tension depends on pitch desired).

171
Q

What parts of the larynx are involved in breathing?

A 
vocal folds
arytenoid cartilage (vocal processes & muscular processes)
172
Q

What is the Bernoulli effect?

A

At a constant volume flow of air, at a point of constriction, pressure decreases as there is an increase of velocity in the flow explaining vocal fold vibration.

Q

The Bernoulli effect closes or opens the vocal folds?

A

It suctions them to close.
