Wood Pencils. When most people think of pencils they think of wooden pencils. Wooden pencils are a staple in most offices and classrooms, especially in environments that require a lot of erasing. Choose pencils with #2 medium-soft lead in varying tip sizes to make different-size lines in bold, crisp detail.
The supraspinatus muscle is one of the musculotendinous support structures called the rotator cuff that surround and enclose the shoulder. It helps to resist the inferior gravitational forces placed across the shoulder joint due to the downward pull from the weight of the upper limb.he 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.
Anatomy: Four muscles are part of the rotator cuff surrounding the shoulder joint, and controls, coordinates and assists movement of the shoulder: M infraspinatus (the lower shoulder blade muscle), M supraspinatus, M subscapularis and M teres minor. The infraspinatus muscle rotates the arm outwards. Acromion Tuberculum majus humeri M. infraspinatus Spina scapulare M. supraspinatus SHOULDER BLADE MUSCLES FROM THE REAR Cause: When a muscle is suddenly subjected to a load in excess of the strength of the muscle, a rupture will occur in the muscle. Rupture of the infraspinatus (the lower shoulder blade muscle) is a common throwing injury (handball).
