Muscles of Respiration - Accessory Muscles of Inspiration

Accessory Muscles of Inspiration

There is some controversy as to which muscles may be considered accessory muscles of inspiration (Kendalll, McCreary, Provance, Rodgers, Romani, 2005). The sternocleidomastoid (elevated sternum) and the scalene muscles (anterior, middle and posterior scalene) are typically considered accessory muscles of breathing ., however the following muscles have also been observed contributing to the breathing: serratus anterior, pectoralis major & minor, upper trapezius, latissimus dorsi, erector spinae (thoracic), iliocostalis lumborum, quadratus lumborum, serratus posterior superior and inferior, levatores costarum, transversus thoracis, subclavius (Kendall et al., 2005). Abdominal muscles relax which is regarded as a function

Scalene muscle activation coincides with the diaphragm even at rest in most humans, suggesting it could be considered a primary muscle of respiration

If a breathing pattern disorder exists, as in the event of an asthma attack, the accessory muscles of inspiration may become overused.

Famous quotes containing the words muscles and/or inspiration:

    What is this beast, she thought,
    with muscles on his arms
    like a bag of snakes?
    What is this moss on his legs?
    What prickly plant grows on his cheeks?
    What is this voice as deep as a dog?
    Anne Sexton (1928–1974)

    For a painter, the Mecca of the world, for study, for inspiration and for living is here on this star called Paris. Just look at it, no wonder so many artists have come here and called it home. Brother, if you can’t paint in Paris, you’d better give up and marry the boss’s daughter.
    Alan Jay Lerner (1918–1986)
