What is Spinoglenoid ligament?
The notch is formed lateral to the point which the spine extrudes from the scapula, with the spinoglenoid ligament (also known as the inferior transverse scapular ligament) forming a foramen by passing from the lateral aspect of the scapular spine to the posterior part of the glenoid. 3.
Which structure passes through spinoglenoid notch?
The suprascapular nerve passes through the notch on its course over the scapula to the dorsal shoulder. The superior transverse scapular ligament passes over the notch and attaches to the base of the coracoid process. The suprascapular artery passes over the ligament.
Where is spinoglenoid notch?
The spinoglenoid notch is located between the base of the spine of scapula and the glenoid process of the scapula that connects the infraspinatus fossa with the supraspinatus fossa, as a passage for the suprascapular nerve and artery, bounded by the inferior transverse scapular ligament (spinoglenoid ligament).
What goes through the spinoglenoid notch?
The suprascapular nerve passes through the notch beneath the superior transverse scapular (suprascapular) ligament, which bridges the notch. The suprascapular artery and vein pass directly over the nerve above the ligament.
What is the Coracoacromial ligament?
The coracoacromial ligament (CAL) connects the acromion and coracoid process of the scapula, forming an osseoligamentous static restraint to superior humeral head displacement.
What is Coracoclavicular ligament?
The coracoclavicular ligament serves to connect the clavicle with the coracoid process of the scapula. It does not properly belong to the acromioclavicular (AC) joint articulation, but is usually described with it, since it forms a efficient means of retaining the clavicle in contact with the acromion.
What is the function of scapular notch?
The supra scapular notch is situated in the lateral part of the superior border of the scapula, adjacent to the base of the coracoid process. The notch is converted into a foramen by the transverse scapular ligament and it serves as a passage for the suprascapular nerve.
What is a Subscapular fossa?
Medical Definition of subscapular fossa : the concave depression of the anterior surface of the scapula.
What is the scapular notch used for?
Great scapular notch shown in red. The great scapular notch (or spinoglenoid notch) is a notch which serves to connect the supraspinous fossa and infraspinous fossa. It lies immediately medial to the attachment of the acromion to the lateral angle of the scapular spine.
What is a Spinoglenoid cyst?
Spinoglenoid notch ganglion cyst is a rare lesion located to the dorsum of glenohumeral joint, leading to entrapment of the suprascapular nerve causing infraspinatus atrophy. Other described features include weakness with external rotation and posterior shoulder tenderness.
Is the coracoacromial ligament needed?
In conclusion, the CAL is an integral component of the coracoacromial arch. Review of the literature demonstrates that the CAL plays an important role in shoulder biomechanics, joint stability, and proprioception.
What is the function of coracoacromial ligament?
Function. Together with the coracoid process and the acromion, the coracoacromial ligament forms a vault for the protection of the head of the humerus.
Where does the spinoglenoid notch form on the spine?
The notch is formed lateral to the point which the spine extrudes from the scapula, with the spinoglenoid ligament (also known as the inferior transverse scapular ligament) forming a foramen by passing from the lateral aspect of the scapular spine to the posterior part of the glenoid. 3
What are the accessory ligaments that support the spine?
Accessory ligaments also support the spine, these are the ligamenta flava, interspinous, supraspinous, nuchal and intertransverse ligaments. Other specialised ligaments are involved in supporting the atlantooccipital and atlantoaxial joints.
How does the vertebral column support the joints?
The movements of the spine are flexion, extension, lateral flexion (sidebending) and rotation. Ligaments of the vertebral column support its joints and stabilize them during spinal movements. The anterior and posterior longitudinal ligaments (ALL, PLL) extend along the entire length of the spine, primarily supporting the intervertebral joints.
Which is part of the body protects the spinal cord?
The back is the body region between the neck and the gluteal regions. It comprises the vertebral column (spine) and two compartments of back muscles; extrinsic and intrinsic. The back functions are many, such as to house and protect the spinal cord, hold the body and head upright, and adjust the movements of the upper and lower limbs.
