Los elevadores de las costillas son un conjunto de músculos profundos de la espalda. Constan de 12 pequeños músculos pares y también pueden considerarse un grupo muscular profundo de la pared torácica. Inserciones: se originan en las apófisis transversas de C7-T11 y se unen a las costillas inferiores. Acciones: elevan las costillas durante la respiración. Contribuyen a la flexión lateral de la columna vertebral. Inervación: ramos posteriores de los nervios raquídeos T1-T12. Irrigación sanguínea: arterias intercostales posteriores.

Pasarse a la versión Premium Frequent questions What are the elevadores de las costillas? The elevadores de las costillas are a group of deep back muscles consisting of 12 paired muscles that assist in the elevation of the ribs during respiration. They are also considered a deep muscle group of the thoracic wall. Where do the elevadores de las costillas originate and insert? These muscles originate from the transverse processes of the cervical vertebrae C7 to T11 and insert onto the lower ribs. This anatomical positioning allows them to effectively elevate the ribs. What is the primary function of the elevadores de las costillas? The primary function of the elevadores de las costillas is to elevate the ribs during breathing, facilitating inhalation. Additionally, they aid in the lateral flexion of the vertebral column. How are the elevadores de las costillas innervated? The elevadores de las costillas are innervated by the posterior branches of the spinal nerves from T1 to T12. This innervation is crucial for their motor function during respiration. What is the blood supply to the elevadores de las costillas? The blood supply to the elevadores de las costillas comes from the posterior intercostal arteries. This vascularisation is essential for their metabolic needs during muscular contractions. Valora este artículo
