What is a scapular elevation?
Elevation of the Shoulder Girdle – a movement where the scapula moves in a superior or upward direction occurring at the Sterno clavicular joints. The scapula moves downward or in an inferior direction. Shrugging the shoulder illustrates elevation and depression of the shoulder girdles.
How is scapular Elevation measured?
This external rotation is necessary to reach full elevation with the arm in the plane of the scapula. The goniometric measurement is performed by placing one arm of the goniometer vertically so that it is 90 degrees from the horizontal (90 degrees to the floor) (Fig. 2-13).
What does scapular region mean?
The scapular region is on the superior posterior surface of the trunk and is defined by the muscles that attach to the scapula (shoulder blade). These muscles can be divided into: As it continues laterally, this spine forms the acromion (the bony high point of the shoulder).
What muscles do scapular elevation?
The elevation is accomplished by the trapezius, levator scapulae, and rhomboid muscles. Depression is accomplished through the force of gravity and the actions of the latissimus dorsi, serratus anterior, pectoralis major and minor, and the trapezius muscles.
What is elevation movement?
Elevation is movement in a superior direction. For example, shrugging is an example of elevation of the scapula. Depression is movement in an inferior direction, the opposite of elevation.
Which muscles elevate the scapula quizlet?
Muscles that move the scapula
- Trapezius – elevate, depress, adduct scapula.
- Latissimus dorsi m. – adduct scapula.
- Levator scapulae m. – elevate scapula.
- Rhomboid minor – elevate and adduct scapula.
- Rhomboid major – elevate and adduct scapula.
- Serratus anterior m. –
- Pectoralis minor m. –
Why is scapular retraction important?
Being able to retract your scapula is important because protracted scapulae make it difficult to move your shoulder joints well. Being able to pull your scapulae into proper position makes it possible to breathe and move freely without the weight of you arms dragging you (literally) down.
What is the main function of the scapula?
The scapula is an important bone in the function of the shoulder joint. It engages in 6 types of motion, which allow for full-functional upper extremity movement including protraction, retraction, elevation, depression, upward rotation, and downward rotation.
What are the 3 processes of the scapula?
The scapula has three processes: the acromion, the spine, and the coracoid process. Muscle attachments to these landmarks are covered in the “Muscles” section. The ventral surface of the scapula abuts the thoracic rib cage and has a large concavity called the subscapular fossa where the subscapularis attaches.
