What respiratory anatomical structures must be intact for ventilation to occur effectively?
Intercostals.
What are the actions from the constructions in respiratory muscles?
Muscles of inspiration include: diaphragm, scalenes, pectoralis minor, and external intercostals. The muscles of expiration include: abdominals and internal intercostals.
Do interchondral external intercostals exist?
No, interchondral external intercostals do not exist. The external intercostal muscles are located between adjacent ribs and are involved in respiratory movements. However, there is no specific structure known as interchondral external intercostals.
Nerve impulses that stimulate inspiration originate in which respiratory center?
The Pontine Respiratory Group stimulates abnormal breathing, called inspiration, during inhalation. The PRG consists of a network of neurons located in the rostral dorsal lateral pons.
What does pump rate simulate?
number of beats per minute stimulates respiratory rate
What is the most important breathing muscle?
The diaphragm is the prime mover of inspiration. It flattens on contraction, increasing the vertical dimensions of the thorax, which draws air into the lungs. The external intercostals also contribute to inspiration. The internal intercostals and rectus abdominis are expiratory muscles.
What is the function of the intercostals?
The Intercostals stabilize the rib cage and assist in respiration
What diseases does wild cherry bark treat?
Coughs, respiratory conditions, asthma, stimulates digestion, eye inflammation.
What is congaplex used for?
It supports and stimulates the immune system and also supports the healthy function of the upper respiratory system
Is the dorsal respiratory group the expiratory center?
No, the dorsal respiratory group is typically associated with the inspiratory phase of breathing, while the ventral respiratory group is considered the expiratory center in the central nervous system.
How does hypoventilation affect respiratory rate?
It is due to CO2 reduction. Low CO2 stimulates chemo-receptors in brain stem. Respiratory rate is reduced in order for CO2 to come back to normal.
What are in the thoracic cavity?
The intercostals and the diaphragm.
