Spine of the scapula

The medial end of the spine the root of the spine lies at the level of the spinous process of the third thoracic vertebra. The scapula and arm are connected to the body by multiple muscle and ligament attachments.

The spine of the scapula is a thick prominent plate of bone that crosses obliquely the medial 45 of the posterior surface of the scapula.

Spine of the scapula. The spine of the scapula is a thick prominent plate of bone that crosses obliquely the medial 45 of the posterior surface of the scapula. This border is faced anteriorly towards the posterior surface of the bone and is attached to it. The spine of the scapula or scapular spine is a prominent plate of bone which crosses obliquely the medial four-fifths of the scapula at its upper part and separates the supra- from the infraspinatous fossa.

At the back of the scapula is the convex and uneven posterior surface which has a protruding ridge of bone spine of the scapula that unevenly separates it into two divisions. The superior supraspinous fossa and the much bigger inferior infraspinous fossa. Along with the spine there are two more processes.

The coracoid and acromion process. The coracoid process is a beak-like bent that projects anterolaterally from the superior. The spine of the scapula is a thick prominent plate of bone that crosses obliquely the medial 45 of the posterior surface of the scapula.

This border is faced anteriorly towards the posterior surface of the bone and is attached to it. The spine of the scapula is commonly in line with the T3 vertebra and the manubrium of the sternum is generally opposite T3 and 4 vertebrae. The trachea divides at the level of vertebrae T5 to 7 when a subject is in the erect position.

It is a triangular plate of bone located on the posterior surface running transversely across the scapula dividing the dorsal surface of the scapula into supraspinous and infraspinous fossae. The two fossae remain connected by the spinoglenoid notch situated lateral to the root of the spine bridged by the spinoglenoid ligament.

Where the spine of the scapula ends at the medial border is called the root of the spine of the scapula. Passively retracting the clients scapula makes it much easier to locate the medial border. FIGURE 5-8 Superior angle of the scapula.

Once the medial border of the scapula has been located palpate along it superiorly until you reach the. The spine of scapula is a prominent plate of bone which crosses obliquely the medial four-fifths of the dorsal surface of the scapula at its upper part and separates the supra- from the infraspinatous fossa. It begins at the vertical border by a smooth triangular area over which the tendon of insertion of the lower part of the Trapezius glides.

Medical definition of spine of the scapula. A projecting triangular bony process on the dorsal surface of the scapula that divides it obliquely into the area of origin of parts of the supraspinatus and infraspinatus muscles and that terminates in the acromion. Related to spine of scapula.

Medial border of scapula. TA the prominent triangular ridge on the dorsal aspect of the scapula providing attachment for the trapezius and deltoid muscles and separating the supraspinous and infraspinous fossae. The acromion is a lateral extension from the spine.

The spine of the scapula transverses the dorsal surface of the bone from the medial margin to the lateral margin. The spine terminates as the acromion which forms the summit of the shoulder. The acromion is a large somewhat triangular or oblong process projecting at first laterally and then curving forward and upward to overhang the.

Scapula The shoulder blade. A flat triangular bone with a prominent near-horizontal raised spine lying over the upper ribs of the back. At its upper and outer angle the scapula bears a shallow hollow with which the rounded head of the upper arm bone the humerus articulates.

The spine of the scapula or scapular spine is a prominent plate of bone which crosses obliquely the medial four-fifths of the scapula at its upper part and separates the supra- from the infraspinatous fossa. Scapula posterior aspect. As seen in Figure 215 the lateral end of the spine projects forwards as the acromion.

The medial end of the spine the root of the spine lies at the level of the spinous process of the third thoracic vertebra. The spine of scapula and the acromion are subcutaneous and are palpable. The trapezius and the deltoid.

Spine of Scapula and Acromion. The spine of the scapula is a thick prominent plate of bone that crosses obliquely the medial 45 of the posterior surface of the scapula. By doing this it reserves the upper 15 for the supraspinous fossa and the lower 45 for the infraspinous fossa.

The scapula and arm are connected to the body by multiple muscle and ligament attachments. The front of the scapula acromion is also connected to the clavicle collarbone through the acromioclavicular joint. As you move your arm around your body your scapula must also move to maintain the ball and socket in normal alignment.

The supraspinous fossa above the spine of scapula is concave smooth and broader at its vertebral than at its humeral end. Its medial two-thirds give origin to the Supraspinatus. At its lateral surface resides the spinoglenoid fossa which is situated by the medial margin of the geloid.

Spine or Spinuous Process is a triangular plate of bone with 3 borders and 2 surfaces. It divides the dorsal surface of the scapula into supraspinous and infraspinous fossae. The posterior border is called the crest of the spine which has upper and lower lips.

The Acromion Process has 2 borders medial and lateral. 2 surfaces and a facet for.
