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. 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.
With the first ribs fixed by neck muscles (scalene muscles and sternocleidomastoid muscle), the intercostals muscles (especially external intercostal muscles and interchondral part of internal intercostal muscles of opposite side), elevate the 2nd to 12th ribs and thus act as inspiratory muscles.
