Elevation and depression are movements above and below the horizontal. The words derive from the Latin terms with similar meanings. [c] Elevation is movement in a superior direction. [19] For example, shrugging is an example of elevation of the scapula. [20] Depression is movement in an inferior direction, the opposite of elevation. [21]
elevation of the scapula at the shoulders (e.g. shrugging shoulders) include: Levator scapulae muscle; Rhomboid major muscle and Rhomboid minor muscle; Trapezius muscle; elevation of the ribs. Pectoralis minor muscle; Scalene muscles; mandible. Medial pterygoid muscle; upper lip. Levator labii superioris; upper lip and wing of nose

They originate on ribs 1–11 and have their insertion on ribs 2–12. The external intercostals are responsible for the elevation of the ribs and bending them more open, thus expanding the transverse dimensions of the thoracic cavity. The muscle fibers are directed downwards, forwards and medially in the anterior part.
The tendon attaches to the top (superior aspect) of the eyeball at an angle of 51 degrees with respect to the primary position of the eye (looking straight forward). The force of the tendon’s pull, therefore, has two components: a forward component that tends to pull the eyeball downward (depression), and a medial component that tends to ...
This angle is formed by the junction of the superior and medial borders of the scapula. The superior angle is located at the approximate level of the second thoracic vertebra. The superior angle of the scapula is thin, smooth, rounded, and inclined somewhat lateralward, and gives attachment to a few fibers of the levator scapulae muscle. [5]
In physiology and medicine, depression [1] refers to a lowering, in particular a reduction in a specific biological variable or the functions of an organ. It is the opposite of elevation. For example, it is possible to refer to "depressed thyroid function" or to a depression of blood flow in a particular area. Further examples:
The sternal angle is a palpable and visible landmark in surface anatomy, presenting as either a slight body ridge or depression upon the upper chest wall which corresponds to the underlying manubriosternal joint. [4] The sternal angle is palpable and often visible in young people. [2]: 319
