What is the function of pectoralis minor?
The Pectoralis minor depresses the point of the shoulder, drawing the scapula inferior and medial, towards the thorax, and throwing its inferior angle posteriorly. It may also help with forced expiration and stablizing the area when other muscles are used.
What is the important muscle of inspiaration?
Most important muscle of inspiration is the diaphragm, which upon contraction, pulls the base of the lung down and increases the pressure inside of the lung, drawing air into the lungs. Other muscles that are not as important except for in forced inspiration are the intercostal muscles and sternocleidomastoid muscles, which only work when forced expiration is required as well :)
What is the difference between normal inspiration and expiration and forced inspiration and expiration?
my wang
Which intercostal muscle help accomplish forced expiration?
internal
When is the intrapleural pressure become positive?
during forced expiration
What does FVC designate?
The greatest volume of air that can be expelled when a person performs rapid, forced expiration.
What is the sternocephalicus muscle?
The sternocephalicus is a part of the sternocleidomastoid muscle, which "passes obliquely across the side of the neck, being enclosed between the two layers of deep cervical fascia." The origin of its name, sternocleidomastoid, stems from the fact that it has two heads, extending from the sternum and the clavicle.The sternocleidomastoid has three major actions; the first is to bring the head to the shoulder. The second is to rotate the head and the third is to assist in "elevating the thorax during forced inspiration."[The quotes are from the 1977 Collector's Edition of Henry Gray's Gray's Anatomy.]
Who is Father Duenas?
He was a priest on Guam martyred during WW II because he was suspected of aiding an American serviceman hiding from the Japanese. He was forced to dig his own grave, then beheaded.
Use of accessory muscles in emphysema?
The accessory muscles of respiration are the sternocleidomastoid, scalenes, serratus anterior, pectoralis major and minor, upper trapezius, latissimus dorsi, erector spinae (thoracic), iliocostalis lumborum, quadratus lumborum, serratus posterior superior and inferior, levatores costarum, transversus thoracis, and subclavius. The diaphragm is the main muscle of respiration (normal/relaxed breathing), assisted by the intercostals. No accessory muscles should be recruited during normal respiration unless there is a respiratory disorder. During quiet inspiration, the diaphragm and intercostals are activated. During quiet expiration, the inspiratory muscles relax and the elastic recoil of the lung tissue combined with intrathoracic pressure causes air to be pushed out of the lungs. There is little or no respiratory activity of the abdominals. When increased oxygen is required during physical activity e.g. when running, accessory muscles will activate to assist forced respiration.
What muscle is contracted to exhale forcibly?
Diaphragm & interna intercostal muscle
Who forced the British to aid India?
No one forced the British to aid India. In fact it is the revers case.Instead of aiding India, Britishers came to India to be aided for their own country since the resources available in India created greed in them to take those away to Britain for development of their 'island' country starved of natural resources.
What might an abnormal increase in venous pressure indicates?
these factors can increase central venous pressure: decreased cardiac output, increased blood volume, venous constriction,forced expiration, muscle contraction
