Complete Scapula in Just 5 mins

[00:00:01]Hello guys. So, today we are going to discuss about the scapula bone. I got to say I think it's triangular bone structure that you could trust me. Video end up I could see I can easily say down below.

[00:00:12]Video end up I could see the landmarks, muscle attachment, and the clinical features. All of them you have to follow.

[00:00:18]So, three important features of the end.

[00:00:21]You have to call it a process which is facing anteriorly. This is spinous process which should face posteriorly.

[00:00:28]And this is the glenoid cavity which should face anterolaterally. I got to get in season you have to get to ask capital orientation coming in below.

[00:00:38]So, this is scapula bone which is also known as shoulder blade. Which is present posteriorly lateral aspect of the thoracic cage and it's extend is from T2 vertebrae to T7 vertebrae and the spinous process set T3.

[00:00:53]So, let's [music] understand the parts of the scapula. It has two surfaces.

[00:00:58]This is anterior surface or posterior surface or also known as subscapular fossa.

[00:01:03]This is posterior surfaces in which the spinous process which divide the posterior surface into a supraspinatus fossa and the infraspinatus fossa.

[00:01:13]It has three borders.

[00:01:15]Lateral border which is also known as axillary border. This is medial border which is also known as vertebral border.

[00:01:22]And this is superior border.

[00:01:25]It has three angles. This is superior angle.

[00:01:28]Inferior angle. And lateral angle where the presence of the glenoid cavity.

[00:01:34]It has three processes. The coracoid process.

[00:01:38]Shaped like projection which is known as spinous process. And this is acromion process.

[00:01:44]So, this is costal surface which is a concave and there is the attachment of muscle called as subscapularis.

[00:01:52]And from medial side there is muscle attachment called as the serratus anterior.

[00:01:58]On the posterior surface, the spinous process, the shelf-like projection, which divide posterior surface into supraspinatus fossa and the infraspinatus fossa.

[00:02:09]The supraspinatus fossa, there is attachment of muscle called as the supraspinatus muscle. And infraspinatus fossa, there is attachment of the infraspinatus muscle.

[00:02:20]So, let's understand the spinous process, which has two surfaces, superior surface and the inferior surface. It has three borders, anterior border, posterior border, and the lateral border. Posterior border is also known as crest of the spine. It has crest has upper lip and lower lip.

[00:02:40]So, on the upper lip of the crest, there is attachment of muscles called as trapezius. And the lower crest of the spine, there is attachment of the muscle called as deltoid.

[00:02:51]From the lateral aspect, so lateral aspect of the upper two-third, there is attachment of the muscle called as teres minor.

[00:03:00]And the lower third, lower one-third, there is attachment of muscle called as teres major. On the inferior angle, there is attachment of muscle, latissimus dorsi.

[00:03:12]On the coracoid process, there is attachment of three muscles, the short head of biceps brachii, coracobrachialis, and pectoralis minor.

[00:03:21]Which is known as the spinoglenoid cavity.

[00:03:24]And on the superior border, there is notch, which is known as suprascapular notch.

[00:03:29]So, this is glenoid cavity. This is supraglenoid tubercle. There is attachment of the muscle called as long head of biceps brachii. And this is infraglenoid tubercle. There is attachment of the muscles called as long head of triceps brachii.

[00:03:44]So, humerus and scapula, this is scapula bone, which is also known as shoulder blade. It is present posterolateral aspect of thoracic cage.

[00:03:51]Its extent is from the T2 to T7 and the spinous process which is present at the level of T3. Orientation coracoid process, glenoid cavity and the spinous process.

[00:04:04]It has two surfaces, costal surface and the dorsal surface. It has three borders, lateral border, medial border and the superior border. Three angles, superior angle, inferior angle and the lateral angle. So this bone which helps in the movements of the upper limb.

[00:04:20]Seats so S for supraspinatus, I for infraspinatus, S for subscapularis and T for teres minor.

[00:04:28]So these are the rotator cuff muscles. I don't know but it's starting with the serratus anterior muscle are at the medial border say with kind of supply with the long thoracic nerve. I don't know what's going to damage to a clinical condition with the winging of scapula.

[00:04:45]So what goes with the scapula?
