Final answer:
The pectoralis minor muscle attaches from ribs three to five to the coracoid process of the scapula.
Step-by-step explanation:
The muscle that attaches from ribs three to five to the coracoid process of the scapula is not the rhomboid minor muscle; however, it seems the student's question has been misunderstood as there is no single muscle that directly runs from these ribs to the coracoid process.
Instead, the pectoralis minor muscle attaches from the third, fourth, and fifth ribs to the coracoid process of the scapula. The pectoralis minor is one of the muscles that position the pectoral girdle, which includes the clavicle and scapula. The coracoid process itself is a short, hook-like structure that provides an attachment site for several muscles of the anterior chest and arm, including the pectoralis minor.
