Innervation together cervical flexion, singly rotate opposite side. Accessory, c2-c3 pubic crest & symphysis cartilage of ribs 5-7. & xiphoid compress abdomen & flex vertebral column. T7-t12 lower 8 ribs iliac crest, linea alba together compress abdomen, singly laterally flex vertebral column. T7-t12, iliohypogastric iliac crest, inguinal ligament cartilage of last 3-4 ribs together compress abdomen, singly laterally flex vertebral column. T8-t12, iliohypogastric, ilioinguinal iliac crest, inguinal ligament, cartilage of last 6 ribs xiphoid, linea alba compress abdomen. Muscles used in breathing xiphoid, catilage of last 6 ribs central tendon pulls central tendon increase thorax length during inspiration. Phrenic inferior border of rib above superior border of rib elevates ribs, increases thorax intercostals. Trapezius below lateral & anteroposterior superior border of rib below inferior border of rib above depresses ribs, decreases thorax lateral & anteroposterior intercostals. Posterior thoracic mucsles occipital, spines c7-t12 clavicle, acromion, scapula spine elevate clavicle & head, adduct-rotate-elevate-depress scapula.
