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).
Glenohumeral dislocation. The glenohumeral joint is the major articulation of the shoulder joint. Dislocation of the glenohumeral joint occurs when the humeral head is moved out of contact with the glenoid cavity. Almost 85% of shoulder dislocations are anterior dislocations.
