Where is the lateral angle of scapula?
The lateral angle of the scapula is at the thickest part of the scapula and forms a feature called the head of the scapula that includes the articular surface called the glenoid cavity.
Where is the medial border of the scapula?
The thin medial border of the scapula runs parallel to the spinous processes of the thoracic vertebrae; hence, it is often called the vertebral border [2]. Four muscles attaches to the medial border.
What is the lateral part of the shoulder?
In human anatomy, the shoulder joint comprises the part of the body where the humerus attaches to the scapula, and the head sits in the glenoid cavity. The shoulder is the group of structures in the region of the joint. The shoulder joint is the main joint of the shoulder….

Where is the axillary border of scapula?
The axillary border of the scapula is the thickest of the three borders of the scapula bone. It extends down from the lower margin of the glenoid cavity all the way along the lateral edge of the scapula to the inferior angle.
Which are borders of the scapula?
Like any triangle, the scapula consists of three borders: superior, lateral and medial. The superior border is the shortest and thinnest border of the three. The medial border is a thin border and runs parallel to the vertebral column and is therefore often called the vertebral border.
What is lateral border?
The lateral border (axillary border) is the thickest of the three borders of the scapula. It begins above at the lower margin of the glenoid cavity, and inclines obliquely downward and backward to the inferior angle.
Is the scapula part of the shoulder?
Your shoulder joint is a ball-and-socket joint. The head of the humerus (upper arm bone) is the ball and the scapula (shoulder blade) forms the socket where the humerus sits. The scapula and arm are connected to the body by multiple muscle and ligament attachments.
What does it mean when your scapula hurts?
The most common cause of shoulder blade pain is a muscle strain. 2 Short-term overuse of your arms and upper torso may be experienced in your scapula. This pain may be accompanied by pain in other muscle groups, such as your shoulder or back, but can be felt only in your shoulder blade as well.
What is the lateral upper section of the scapula?
The lateral angle of the scapula or glenoid angle also known as the head of the scapula is the thickest part of the scapula. It is broad and bears the glenoid cavity on its articular surface which is directed forward, laterally and slightly upwards, and articulates with the head of the humerus.
Why is the lateral border of the scapula thick?
A thick ridge adjoins the lateral border. This part of the bone is almost rod-like acts a lever for the action of serratus anterior in overhead abduction of the arm. The prominent spine of scapula divides the surface into a smaller supraspinous fossa and a larger infraspinous fossa.
What is the purpose of the lateral border of the scapula?
What structure is associated with lateral border of scapula?
The lateral angle of the scapula is the location of the glenoid cavity; this is where the humeral head articulates with the scapula. At the margins of this cavity, a fibrocartilagenous structure called the glenoid labrum acts to deepen the cavity as to accommodate more of the humeral head.
What is the lateral angle of the scapula?
The lateral angle of the scapula or glenoid angle also known as the head of the scapula is the thickest part of the scapula. It is broad and bears the glenoid cavity on its articular surface which is directed forward, laterally and slightly upwards, and articulates with the head of the humerus.
What is the vertebral border of the scapula?
The vertebral border (of the scapula) is a structural feature on the scapula bone (also known as the shoulder blade or shoulder bone). The vertebral border of the scapula is also known as the medial border of the scapula, the “internal border of the scapula” and sometimes as the “base (of the scapula)”.
What are the features of the scapula?
The scapula is a thin triangular shaped bone that lies on the dorsal surface of the rib cage. The most prominent features of the scapula are the processes for the attachment of muscles. The most prominent process on the posterior surface of the scapula is the spine which terminates in the acromion process.
What is the importance of the scapula?
The scapula, more commonly called the shoulder blade plays an important role in the overall function of the shoulder. The scapula sits on the outside of the ribcage. It is attached to the ribcage by ligaments and muscles, called the scapula stabilizers. Many muscles attach onto the scapula, including the muscles of your rotator cuff.
