On any given day, it is estimated that 283 million people are exposed to the possibility of a major shake up. The areas where major plates of the earth touch are the places where quakes are most likely to happen. These junctures between continental plates are called faults, and living on a fault line puts humans at risk of suffering damage or death at the hands of an earthquake.
The subscapularis is a large triangular muscle which fills the subscapular fossa and inserts into the lesser tubercle of the humerus and the front of the capsule of the shoulder-joint.o and Burkhart even tagged the subscapularis tendon hypercritically as the forgotten tendon. That arises by the gap of the described tear prevalence in cadavers between 29 and 37% and in clinical studies around 27%.
The subscapular bursa is also between the tendon and the inner part of the capsule, and opens into the joint between the upper and middle gleno-humeral ligaments, by a large aperture on and in which the upper part of the tendon lies as it passes out towards the humerus. Dorsal Surface (see Fig.he covering of Subscapularis is really responsible for the axillary border as a ridge, and so we find that the origin of this muscle extends out to the axillary border, and follows this even when, as frequently occurs, it turns on to the dorsal surface for a little distance between the Teres major and minor (Fig.
