Where does the scapula meet the acromion process?
The clavicle articulates at one end with the sternum (chest bone) and with the acromion of the scapula at the other. This articulation between the acromial end of the clavicle and the acromion of the scapula forms the roof of the shoulder.
What is the acromion process of the scapula?
The acromion (plural: acromia), also known as the acromial process, is a small projection of the scapula that extends anteriorly from the spine of the scapula.
What does the acromion of the scapula articulate with?
The scapula articulates with the clavicle through the acromion process, a large projection located superiorly on the scapula forming the acromioclavicular joint. The scapula also articulates with the humerus of the upper arm to form the shoulder joint, or glenohumeral joint, at the glenoid cavity.
What attaches to the acromion process?
Two major muscles, the deltoid and trapezius, attach to the acromion. The deltoid, which abducts the arm at the shoulder, forms its origin along the acromion, the spine of the scapula, and the clavicle.
Is the acromion process anterior or posterior?
The acromion process is a palpable lateral and enlarged extension of the posterior spine of the scapula which projects anterolaterally to the spine. It arches over the glenohumeral joint and articulates with the lateral acromial end of the clavicle to make up the synovial acromioclavicular joint.
Where are the scapula?
The scapula is a flat, triangular-shaped bone (colloquially as the “shoulder blade”). It is located in the upper thoracic region on the dorsal surface of the rib cage. It connects with the humerus at the glenohumeral joint as well as the clavicle at the acromioclavicular joint to form the shoulder joint.
What is acromion and coracoid process?
The coracoid process (from Greek κόραξ, raven) is a small hook-like structure on the lateral edge of the superior anterior portion of the scapula (hence: coracoid, or “like a raven’s beak”). Pointing laterally forward, it, together with the acromion, serves to stabilize the shoulder joint.
Is acromion process anterior or posterior?
Posterior – inferior view, anatomical position The acromion process articulates with the distal (acromion end) of the clavicle. The acromion process of the scapula is of functional importance because it is the origin for: 1.
What connects the scapula and clavicle?
The acromioclavicular joint connects the clavicle to the acromion, which is part of the shoulder blade or scapula.
Which part of the scapula is connected to the acromion process quizlet?
Acromial end–The lateral end of the clavicle called acromial extremity is broad and flat and articulate with acromion process of scapula to form acromioclavicular joint.
What bone is the scapula?
scapula, also called shoulder blade, either of two large bones of the shoulder girdle in vertebrates. In humans they are triangular and lie on the upper back between the levels of the second and eighth ribs.
Is the scapula anterior or posterior?
The scapula, also known as the shoulder blade, is a flat triangular bone located at the back of the trunk and resides over the posterior surface of ribs two to seven.
What is the function of the acromion process?
A non-union between the meso- and meta-acromia,the most common or typical os acromiale
How to find the acromion process?
large, rounded, triangular shape. Find the acromion process, which is the bony point at the end of the shoulder. The injection site will be below the bone and above the axillary fold/armpit. 3. Administer the vaccine correctly. Inject the vaccine into the middle and thickest part of the muscle. Insert the needle at
What are the 3 types of acromion?
flat inferiorly
How to palpate acromion process?
When palpating the coracoid process, notice that its apex (tip) points laterally. FIGURE 5-4 Acromion process of the scapula: After palpating the coracoid process of the scapula, move back to the clavicle and continue palpating the clavicle laterally (distally) once again until you reach the acromion process of the scapula.
