today's topic in the white house of anatomy is sceptile the another name of the scapula bond is a shoulder blade now it is a flat triangular shape bond which situated at the posterior electron aspect of a thoracic kitchen against second to seven three now first we will see the sign determination of the scapula to determine the side determination again we will we should keep in our mind the three points one is interior posterior second medial lateral and third superior inferior first we will see the entero or posterior aspect coral point process is facing interior the second medial the large glenoid cavity is facing literally third superior inferior the thick literal water is extending from the glenoid cavity above to the inferior angle below that means the glenoid cavity should face literally as well as superior so the given scapular is off of right now we will see the feature and the attachment of the scapula it is having two surface three border three angle and three processes first we will talk about the two surfaces the two surfaces are the coastal surface and the dorsal surface first talking about the posterior surface the coastal surface is concave and it is facing integrally and it will fits with the ribs now the coastal facet if you see it will mark by three to four oblique reaches which will provide attachment of a multiple muscle subscapularis so coastal surface give origin to subscapularis muscle now talking about the dorsal surface the torso surface is convex in its upper part it will provides attachment to the spine of a scapula which will divide this torso surface of the scapula into two parts the smaller supraspinous force up and larger infraspinous forces and these two forces are interconnected through spinal note now we will see the attachment over the torso surface the smaller supra spinous fossa will give origin to the supraspinatus muscle this muscle will also originate from the superior surface of the spine of the skin the larger infraspinous fossa will give origin to the infraspinatus muscle this infraspinatus muscle will also originate from the inferior surface of the spine of the scapula now the relation over the dorsal surface this spinal glenoid this one it will provide the passage the structure passed through this node is suprascapular now and suprascapular waste now the second feature that is the border it is having three water the superior water medial water and the little water first talking about the superior water the superior border is very thin and very small now at the lateral end of the superior water near the root of the coracoid process you will see one note this known node is known as a suprascapular node now above the suprascapular nodes it will provides attachment or suprascapular ligament now the important structure passes below this ligament and above this ligament yes of course this ligament will convert this suprascapular nose into the suprascapular now we will see which structure passes below it the suprascapular now will passes below the suprascapularly government and the suprascapular artery and the wing that is the suprascapular vessels that will passes above the suprascapular ligament superior border near the suprascapular nodes over here it will use origin to the inferior belly of a homo hyulic musk now talking about the second border that is the medial border the longest one it will extend from the superior angle above to the inferior angle below we will see the attachment over the medial water for the attachment the medial border we will see that it's two aspects the coastal aspect and the doors are restricted the medial border over its coastal aspect receives the insertion of eight slips of scientist interior muscle and over the dorsal aspect the medial border receives the insertion of first levator scapulae muscle extending from the superior angle to the root of the spine of sceptical the second rhomboideus miner that is inserted at the level of the root of spine of scapula and rhomboideus major from the root of spine of scapula to the inferior angle now the large border is the lateral water that is the thickest one extending from the green with heavily above to the inferior angle now the little border over its torso aspect you origin of two muscle from its upper two thirds give origin to the periost miter and from lower one third you put it into the biggest major muscle the next part is it is having three angles that is superior angle inferior angle and the literature the talking about the first superior angle that is the angle between the super superior border and the medial water the second angle inferior angle is the angle between the medial border and the lateral border and the third and the most important is a lateral angle the lateral angle is also known as a head of the scapula and it will gears the larger greenhouse cavity now this glenoid cavity will articulate with the heel of the humerus to form the shoulder joint or give or the margin of the clinoid cavity provides attachment to the fibrocartilage cartilaginous ring that is known as a glenoid labrum now the importance of this glenoid lamina labrum is that it will deepens the glenoid cavity so that the head of the humerus will firmly articulate with the glenoid heavy now above the glenoid cavity you will have the supraglenoid and below you will have the infrarenoid river now the supraglenoid tubercle will gives origin to the long head of biceps brachii from the inner provides attachment to the long head origin of the long head of the triceps muscle one thing also you have to remember the glenoid cavity is a pressure type of the epiphysis now the last part in the scapula is the process it is having three process the first one is a spine of scapula or a spinous process of septum acromion process second and the third is a coracoid process we will see one by one the first the spine of the scapula first process spine of the scapula or the spinous process of the skeptic now this is a this process is a triangular plate of the bone that is attached to the dorsal surface of the scapula and yes it divides it into the supraspinous and the infraspinous fossa now the spine of the scapula is having two surfaces superior and an inferior and having three water the anterior posterior and the lip the superior surface will give origin to the part of the supraspinatus muscle and the inferior surface gave origin to the part of the infraspinatus muscle nta border of the spinous process will attach to the dorsal aspect of the scapula posterior border is a thick which is known as a crest of the spine of the scapula and it is having two lip upper lip and lower lip this upper lip will provides insertion of a trapezius muscle and the lower lip will give origin to the deltoid muscle now this is the first one the second is a acromion process now the acromion process is an example of the traction epithesis it is a flat flattened process which is in direct continuity with the spine of the scapula literally now it is having two surface superior inferior having one teeth and two body medial border and the lateral superior surface is subcutaneous inferior surface is related to the subatomic versa its steep will provides attachment to the corey acromion ligaments now talking about the border on the medial border somewhat entirely it will show one oval facet which will articulate with the lateral end of the clerical to form the acromioclavicular joint which is a plane variety of the cylon joint after attachment the remaining part of the medial border receives the insertion of a trapezius muscle the little water will stow three to four small deltoid tubercle which will give origin to the acronym fiber of a multi-permanent deltoid muscle the the last process is a coreopoint process the coropoid process is directed forward and somewhat literally now it is also having superior surface inferior surface deep medial water and the later water now the t of a coral point process remember it is a atomistic type of the epithesis the coracoid process will provides attachment of three ligaments and three muscles first we will talk about the muscle the teeth of the coracoid muscle give origin to the short head of biceps brachii muscle and the boreaco brachialis muscle together its medial border and somewhat superior surface will receive the insertion of a pectoralis mind now talking about the ligaments its literal border provides attachment to the oreco acromion ligament first its root will gives attachment to the oregon humeral ligament and third its superior surface and the root will provides attachment to the core clavicular ligament now we will see in the large the applied anatomy of the scapula the first one is the winging of a scapula it is a clinical condition in which there is a paralysis of a serratus anterior muscle due to injury of its nose of mind that is known to serratus anterior or long forest signal in the beginning of scapular the medial border of the scapula will become undue prominent when the patient is doing the pushing or punching movement the second applied anatomy is a scaphoid scapula normally in the scapula the medial border is a convex medium but in the scaffold scapula the medial border will become concave laterally the thing it is a clinical condition which according to the blockage between the first part of the subclavian artery and the third part of the axillary so the energetic channel around the skeptic open up and you can see the visible pulsation in the area of the scapula that is known as the positive scale now the last part we will summarize summarize the scapula the scapula is having two surface poster surface torso surface adding three quarter superior water medial border lateral water having three angle superior angle inferior angle lateral angle and the three processes spine of scapula achromic process coronal process now many times in the exam you will be asked the type of the epithelius present in the scapula the first one the glenoid cavity is a pressure type of the artificial acromion process is the production type of the epiphysis and the thief of the photovoltaic process is a atomistic type of if you like our video like it subscribe it and share with your friends
