What bone is posterior to the scapula?
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.
Is the scapula anterior or posterior?
The scapula, or shoulder blade, is a flat, triangular bone located to the posterior of the shoulder. The scapula articulates with the clavicle through the acromion process, a large projection located superiorly on the scapula forming the acromioclavicular joint.
How you can tell the anterior from the posterior side of the scapula?
The wider curve opens to the posterior side and the smaller curve opens to the anterior side. Make sure the conoid tubercle is on the inferior side. How can you tell the difference between a left scapula and right scapula? The coracoid process (hook-shaped and on the transverse plane) is on the anterior side.
What is the anterior projection of the scapula?
Subscapular Fossa – this is on the anterior (front) surface of the shoulder blade. The subscapularis originates here. Coracoid Process – beak shaped bony prominence on the anterior surface of the scapula, serves as the attachment site for several muscles.
Which is the posterior surface of the body of the scapula?
In humans they are triangular and lie on the upper back between the levels of the second and eighth ribs. A scapula’s posterior surface is crossed obliquely by a prominent ridge, the spine, which divides the bone into two concave areas, the supraspinous and infraspinous fossae.
Which bone is the scapula?
shoulder blade
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.
Is the scapula posterior?
The back of the scapula (also called the dorsal or posterior surface) is arched from above downward, and is subdivided into two unequal parts by the spine of the scapula. The portion above the spine is called the supraspinous fossa, and that below it the infraspinous fossa.
Which bone is anterior to the scapula?
clavicle
The clavicle is a vaguely z-shaped bone which articulates with the scapula in the anterior and articulates with the sternum in the posterior. The flatter broader end is the acromial extremity, which articulates with the acromion process of the scapula.
How do you identify the scapula?
Left–In order to determine if a scapula is right or left, orient it so the glenoid cavity (articulating surface) faces laterally (outward) and the spine is posterior (toward back) and superior (upper). The coracoid process should be anterior and superior.
Which marking are clearly visible from a posterior view of the humerus?
Olecranon fossa (Fossa olecrani) is a prominent, triagular-shape depression on the distal posterior surface, superior to the trochlea.
What attaches to the anterior scapula?
Anterior Scapula Bone Anatomy This area is an attachment point for the rhomboid major, rhomboid minor and serratus anterior muscles.
Which region of the scapula is found on the anterior surface?
The subscapular fossa is located on the anterior surface of the scapula.
