The primary center develops near the glenoid cavity throughout the 8th week of development. The authors described in this report the mode of attachments of muscles along the medial border of the scapula, as seen in sixty adult Indians. Back Muscles: The muscles of the back that work together to support the spine, help keep the body upright and allow twist and bend in many directions. The coracoid process is an anteriorly projecting hook-like process on the superolateral edge of the scapula that projects anterolaterally. Intermediate Back Muscles […] The scapula also articulates with the humerus of the upper arm to form the shoulder joint, or glenohumeral joint, at the glenoid cavity. The posterior surface is a site of attachment for the majority of the rotator cuff muscles of the shoulder. It supplies three longitudinal ridges, which in turn supply connection to the intramuscular tendons of subscapularis muscle. Due to its flat nature, the scapula presents two surfaces and three borders; the front-facing costal surface and the rear-facing dorsal surface, as well as the superior, lateral, and medial borders. It articulates with the humerus at the glenohumeral joint, and the clavicle at the acromioclavicular joint. The scapula has two surfaces, three borders, three angles, andthree processes. Serratus anterior is inserted along the medial border of the costal surface; 1 digitation from the superior angle to the root of the spine, 2 digitations to the medial border, 5 digitations to the inferior angle of the scapula. levator scapulae, rhomboideus minor and romboideus major. The acromioclavicular ligament attaches the distal end of the clavicle to the acromion of the scapula and provides horizontal stability.

Key facts about the rhomboid muscles Origin Rhomboid minor: Nuchal ligament, Spinous processes of vertebrae C7-T1 Rhomboid major: Spinous process of vertebrae T2-T5 Insertion Rhomboid minor: Root (medial end) of spine of scapula Rhomboid major: Medial border of scapula (from inferior angle to root of spine of scapula) Teres major arises from lower 1/3rd of the rough strip on the dorsal aspect of the lateral border. This part of the bone is almost rod-like: It acts as a lever for the action of the serratus anterior in overhead abduction of the arm. The lateral surface of the scapula meets the humerus. Deltoid arises from the lower border of the crest of the spine and from lateral border acromion. The trapezius is inserted into upper border of the crest of the spine and into medial border of the acromion of the scapula. Side determination of scapula || Attachment of scapula || scapula … Muscles inserted to the scapula act on it, moving it, whereas those originating from it act on parts to which they are inserted. Although sturdy in cartilagenous fish, both plates are generally small in most other fish, and may be partially cartilagenous, or consist of multiple bony elements. The glenoid labrum is a fibrocartilaginous rim attached around the margin of the glenoid cavity of the scapula. This is because its point of origin is the anterior chest wall, so the muscle itself extends around the thoracic cage in order to reach its designated point of insertion. The superolateral surface of the costal scapula is the coracoid process. The scapula is an important bone as each scapula provides a point of attachment for a number of muscles that make up the arm and shoulder. The coracoacromial ligament connects the coracoid process to the acromion of the scapula. Another thick ridge adjoins the lateral border. It also articulates with the humerus and clavicle, forming the glenohumeral (shoulder) joint and acromioclavicular joint respectively. Another muscle, the Pectoralis minor, comes from the anterior chest wall, to be inserted into the coracoid process of the scapula. Woosh. Rhomboideus major is inserted into the medial border (dorsal aspect) between the root of the spine and inferior angle of the scapula. 4. This side of the scapula is relatively unremarkable, with a concave depression over most of its surface, called the subscapular fossa. The margin of the facet on the medial aspect of the acromion of the scapula gives attachment to the capsule of the acromioclavicular joint. It goes transversely beyond the scapula, dividing the surface into two-. The spine grows taller and thicker as it moves laterally and superiorly toward the shoulder joint. Costal aspect of the scapula with attachments of muscles mapped out. A scapula’s posterior surface is crossed obliquely by a prominent ridge, the spine, which Start studying Neck Muscle attachments. The shoulder joint is considered a ‘ball and socket’ joint. Muscles attached to the three borders of scapula Medial border – Costal surface (including that of inferior angle) provides attachment( insertion) to serratus anterior . Medial border – D orsal surface form above downwards provide attachment to three muscles i.e. The spinoglenoid ligament links the spinoglenoid notch of the scapula. The coracoacromial ligament is connected to the lateral border of the coracoids process and to the medial side of the tip of the acromion process of the scapula. How To Protect Your Eyes From Electronics Devices? The subcoracoid center develops in the root of the coracoid process throughout the 10th year and fuses by the 16th to 18th years of age. SCAPULA Provide attachment for three different groups of muscles. The scapula, also called the shouder blade , is either of two large, roughly triangular flat bones found on either side of the upper back, and forming part of the pectoral ( shoulder ) girdle of humans and other vertebrates. The margin of the glenoid cavity of the scapula gives adjunct to the capsule of the shoulder joint and to the glenoid labrum. Two more muscles that are inserted into the scapula are the Serratus anterior and the Pectoralis minor.

An abnormally projecting inferior angle of the scapula is identified as a winged scapula and can be produced by paralysis of the serratus anterior muscle. Rhomboideus minor is inserted into medial border (dorsal aspect) opposite to root of the spine. The suprascapular ligament lies above the ligament. Inferior belly of omohyoid arises from the upper border near suprascapular notch of the scapula. The other 10 muscles are all inserted into the humerus. bodies of upper thoracic (T123) and lower cervical (C567) vertebrae, transverse processes mid-cervical (C345) vertebrae 1. Subscapularis arises from the medial 2/3rds of the subscapular fossa. The suprascapular ligament links across the suprascapular notch and converts it into a foramen which transmits the suprascapular nerve. Insertion: (distal attachments) a. Medial border of the scapula between spine and superior angle. The Supraspinatous and Infraspinatous originate from the supraspinous and infraspinous fossae, respectively, while the Subscapularis originates from the subscapular fossa located on the other (anterior) side of the scapula. The scapula has three borders Anatomy of Scapula in 3d along with annotations Borders Scapula has three borders and two basic surfaces. The suprascapular nerve travels through the notch and provides motor supply to the supraspinatus muscle and infraspinatus muscle, as well as sensation to the acromioclavicular joint. Intermediate Back Muscles and c. Deep Back Muscles Superficial Back Muscles Action Movements of the shoulder. The scapula ossifies from one primary center including seven secondary centers. If the scapula defaults to properly elevate the acromion, shoulder impingement may develop. It is the position of the glenohumeral joint, and of numerous muscle attachments. Also share? The image of the upper back is assumed to be wing-like. It is a triangular, flat bone, which attachment for 17 muscles. The back muscles can be three types. The Deltoid originates from both the scapula and the clavicle, so just like the Trapezius, it’s attached to the spine of the scapula. In this situation, the sides of the scapula nearest the spine are located outward and backward. The front of the scapula (acromion) is also connected to the clavicle (collarbone) through the acromioclavicular joint. a. Superficial Back Muscles b. The different types of scapula surgery involve either operating on the blade of the scapula itself, or on the close attachments of four majorteres minor The Serratus anterior is inserted to the whole length of the medial border of the scapula, anterior to the three other muscles mentioned above. There is a total of 17 muscles connected to the scapula, 11 of which originate from it, whereas 6 others have it as a point of insertion. The scapula performs a significant role in shoulder impingement syndrome.
