The Levatores costarum (), twelve in number on either side, are small tendinous and fleshy bundles, which arise from the ends of the transverse processes of the seventh cervical and upper eleven thoracic vertebrae
They pass obliquely downward and laterally, like the fibers of the Intercostales externi, and each is inserted into the outer surface of the rib immediately below the vertebra from which it takes origin, between the tubercle and the angle (Levatores costarum breves).
Each of the four lower muscles divides into two fasciculi, one of which is inserted as above described; the other passes down to the second rib below its origin (Levatores costarum longi).
Their role in normal inspiration, if any, is uncertain. They may play a role in vertebral movement and/or proprioception.

- Frewein J, Buff E.AbstractIn the anatomical literature there are inconsistencies in the description of the levatores costarum muscles in man and in the domestic animals, and their innervation either by the dorsal or the ventral branches of the thoracic nerves. Therefore we studied the form, structure and, with the aid of the dissecting microscope, the innervation of these muscles in 7 dogs, 8 cats, 5 horses and 12 pigs. In the dog, cat and horse, mm. levatores costarum are present from the second to the last rib. In the pig, these muscles are present from the second to the 15th rib, even in individuals with 16 pairs of ribs. Mm. levatores costarum longi and a levator of the first rib could not be found in the domestic animals although these muscles are described in man. All mm. levatores costarum are innervated by branches of the lateral branch of the ramus dorsalis of the respective thoracic nerve. An additional branch of the r. muscularis proximalis of the intercostal nerves 1-3 innervates the lateral part of the levator muscles of the second to the fourth rib.
