Intercostals.
Muscles of inspiration include: diaphragm, scalenes, pectoralis minor, and external intercostals. The muscles of expiration include: abdominals and internal intercostals.
number of beats per minute stimulates respiratory rate
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.
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.
The Intercostals stabilize the rib cage and assist in respiration
Coughs, respiratory conditions, asthma, stimulates digestion, eye inflammation.
It supports and stimulates the immune system and also supports the healthy function of the upper respiratory system
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.
The intercostals and the diaphragm.
intercostals
The sternocleidomastoid muscles are the ones that flex when the intercostals are flexed. This will also cause the scalene muscles to flex.
