Vegetation acts as an interface between the atmosphere and the soil. It increases the permeability of the soil to rainwater, thus decreasing runoff. It shelters the soil from winds, which results in decreased wind erosion, as well as advantageous changes in microclimate.
The shoulder is a ball-and-socket type of joint and is anatomically referred to as the gleno-humeral joint, describing the two bony structures involved. The socket is the glenoid cavity, a cup-shaped piece of bone that juts out from a corner of the shoulder blade (scapula).
4. The glenoid cavity is formed by the scapula bone alone. But the coracoid is attached to it as a process. 5. Comparatively the scapula is smaller. It is in the form of a flattened and curved articulating ventrally. 5. The scapula is long and blade-Eke. It is sabre-shaped bone extending dorsally over the ribs and articulating anteriorly with the coracoid.
