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.
Function. The main tasks of the rectus abdominis muscle and the lateral abdominal muscles are the movement of the trunk, stabilization of the vertebral column and the tensioning of the abdominal wall.They are responsible for the abdominal press increasing the intra-abdominal pressure (e.g. during defecation or vomiting).n particular, the rectus abdominis muscle does a ventral flexion (flexion of the trunk or erection of the pelvis) and thus is an important antagonist of the intrinsic back muscles.
