| middle scalene muscle | <anatomy, muscle> Origin, costotransverse lamellae of transverse processes of second to sixth cervical vertebrae; insertion, first rib posterior to subclavian artery; action, raises first rib; nerve supply, cervical plexus. Synonym: musculus scalenus medius, middle scalene muscle. (05 Mar 2000) |
| clavicular part of pectoralis major muscle | pars clavicularis musculi pectoralis majoris, clavicular head of pectoralis major |
