Muscles Of Thorax And Abdominal Wall Diagram Quizlet Vrogue C Muscles that compress the abdominal wall and laterally rotate the waist. term. deltoid abducts arm, flexes, extends, medially, and laterally rotates humerus. definition. clavicle, acromion, spine of scapula, deltoid tuberosity of the humerus. location. These muscles of the anterolateral abdominal wall can be divided into four groups: the external obliques, the internal obliques, the transversus abdominis, and the rectus abdominis (figure 11.16 and table 11.6). figure 11.16 muscles of the abdomen (a) the anterior abdominal muscles include the medially located rectus abdominis, which is covered. There are 11 pairs of external intercostal muscles. they run inferoanteriorly from the rib above to the rib below, and are continuous with the external oblique of the abdomen. attachments: originate at the lower border of the rib, inserting into the superior border of the rib below. actions: elevates the ribs, increasing the thoracic volume. The intercostals (external, internal and innermost), subcostals and transversus thoracic are the 5 muscles which comprise the thoracic cage and are therefore considered muscles of the thorax. together, these muscles alter the volume of the thoracic cavity through moving the rib cage appropriately during respiration. in this section, learn more.

The thoracic, or chest wall, consists of a skeletal framework, fascia, muscles, and neurovasculature – all connected together to form a strong and protective yet flexible cage. the thorax has two major openings: the superior thoracic aperture found superiorly and the inferior thoracic aperture located inferiorly. Action head flexion, contraction of neck muscles, laterally flexes head. trapezius. origin occipital bone, ligamentum nuchae and spines of c7 and all thoracic vertebra. insertion acromion and spine of scapula and lateral third of clavicle. action stabilizes, raises, retracts, elevates, depresses scapula. deltoid.
