Monocytes are usually identified in stained smears by their large kidney shaped or notched nucleus. These change into macrophages after entering into the tissue spaces, and in endothelium can transform into foam cells.
As a quick overview, the muscles that attach to the first rib are: subclavius, anterior scalene, serratus anterior, middle scalene, and levator costae.The job of these muscles is either to fix the rib in place or draw it upwards.lso present are the superior intercostal artery and vein.

Ribs, or costae, are elongated, curved, flattened bones that originate on or between the thoracic vertebrate and end in the wall of the thoracic cavity. Humans have 12 pairs of ribs, the first 7 are true ribs connected to the sternum by separate cartilaginous extensions called the coastal cartilages. Ribs 8-12 are called false ribs because they do not connect directly to the sternum. Ribs 11&12 are called floating ribs because they do not connect to the sternum at all.
