The supraspinatus (plural supraspinati) is a relatively small muscle of the upper back that runs from the supraspinatous fossa superior portion of the scapula (shoulder blade) to the greater tubercle of the humerus. It is one of the four rotator cuff muscles and also abducts the arm at the shoulder. The spine of the scapula separates the supraspinatus muscle from the infraspinatus muscle, which originates below the spine. The supraspinatus muscle arises from the supraspinous fossa, a shallow depression in the body of the scapula above its spine. The supraspinatus muscle tendon passes laterally beneath the cover of the acromion. Research in 1996 showed that the postero-lateral origin was more lateral than classically described. ... https://www.youtube.com/watch?v=olL7FlKadDw

What does ANAPHASE LAG mean? ANAPHASE LAG meaning - ANAPHASE LAG definition - ANAPHASE LAG explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. One of many ways to induce Aneuploidy, Anaphase Lag is a mechanism by which a sister chromatid is lost through the course of cell division due to improper spindle formation and subsequent segregation of chromatids. This event can occur during both meiosis and mitosis with unique repercussions. In either case, anaphase lag will cause one daughter cell to receive a complete set of chromosomes while the other lacks one paired set of chromosomes, creating a form of monosomy. The survival of this monosomic daughter cell will depend on which sister chromatid has been lost as well as the background genomic state of the cell. The passage of abnormal numbers of chromosomes will have unique consequences with regards to mosaicism and development as well as the progression and heterogeneity of cancers. There are two notable mechanisms that cause Anaphase Lag, each of which are characterized by merotelic attachments of kinetochores to the microtubules responsible for chromatid separation. Merotelic attachments occur when a single centromere kinetochore attaches to microtubules originating from both spindle poles of the dividing cell. The merotelic attachments can occur in two ways: centrosome spindle attachments from both poles on the same chromatid kinetochore or the formation of a third centrosome whose microtubule spindles attach to a chromatid kinetochore. Because the chromatid is being pulled in two opposing directions or away from the correct centriole, it cannot migrate to the mass of segregated chromatids at either pole. If the migration is significantly delayed the reformation of nuclei will begin to occur without a full complement of chromosomes. This nuclear envelope formation is also seen for the lone lagging sister chromatid, forming a micronucleus. The micronucleus has the capacity to persist in the daughter cell but with abnormal replication and maintenance machinery. This allows for the accumulation of mutations, increasing the potential for future miss-segregation events. In total these events cause problematic aneuploid cells with increased genomic instability. This has important implications in the development and persistence of cancers as well as debilitating developmental diseases. ... https://www.youtube.com/watch?v=LWhF2jDOWac
