What is the anterior side of the scapula called?
Anteriorly, on the costal surface, is the shallow subscapular fossa. Laterally is the glenoid fossa. Superiorly is the acromion that is continuous with the scapular spine and arcs anteriorly over the humeral head.
Which bone is anterior to the scapula?
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.
What is the most anterior structure of the scapula?
The superior border of the scapula extends from the superior angle to the coracoid process. The coracoid process is a hook-like structure that comes off anteriorly from the lateral superior aspect of the ventral side of the scapula. Like the acromion, it is an attachment point for muscles and ligaments.
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.
Is the scapula anterior or posterior?
Scapula Bone – Introduction The scapula is a flat, triangular-shaped bone that lies adjacent to the posterior surface of ribs. Seventeen muscles attach to the scapula, and it articulates with the clavicle to form the shoulder girdle or pectoral girdle, which supports movements of the humerus.
Is the sternum anterior or posterior?
The sternum (or breastbone) is a flat bone located at the anterior aspect of the thorax. It lies in the midline of the chest and has a ‘T’ shape. As part of the bony thoracic wall, the sternum helps protect the internal thoracic viscera – such as the heart, lungs and oesophagus.
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.
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.
What is posterior and anterior?
Posterior means towards the back of the body. So, posterior means towards the ‘back,’ and anterior means towards the ‘front. ‘
What is the posterior part of the sternum?
In mammals the sternum is divided into three parts, from anterior to posterior: (1) the manubrium, which articulates with the clavicles and first ribs; (2) the mesosternum, often divided into a series of segments, the sternebrae, to which the remaining true ribs are attached; and (3) the posterior segment, called the …
What is another name for the lateral border of the scapula?
The axillary border (or “lateral border”) is the thickest of the three. It begins above at the lower margin of the glenoid cavity, and inclines obliquely downward and backward to the inferior angle. It is referred to as the caudal border in animals.
Where is the anterior?
Anterior refers to the front of the human body when used to describe anatomy. The opposite of anterior is posterior, meaning the back of the human body. The term anterior is typically used in combination with other words that describe the location of a body part.
What is winged scapula and best exercises to fix it?
– Set the Scapula. This is a basic exercise where you set the scapula and activate the muscles around the shoulder blades.
What are the symptoms of a torn scapula?
The most common symptoms of scapular dyskinesis include: Pain and/or tenderness around the scapula, especially on the top and medial (inner) border. Weakness in the affected arm—your arm may feel “tired” or “dead” when you try to use it vigorously. Fatigue with repetitive activities, especially overhead movements.
What muscles attach to the posterior surface of the scapula?
Inserting on the scapula Trapezius muscle – it inserts superiorly along the spine, acromion process, and clavicle. Levator scapulae muscle – they insert into the superior angle and medial border (superior to the spine). Rhomboid major muscle – its insertion is the medial border (inferior to the spine). Rhomboid minor muscle – it inserts above the scapular spine.
Which terms correctly describe the scapula?
The scapula is commonly referred to as the shoulder blade. It connects the humerus bone of the arm to the collarbone. There are only three muscles that are responsible for enabling the movement of the shoulder blade. The trapezius muscle implants into the collarbone. It is responsible for movement of the shoulder and head.
