Subscapular fossa of scapula. The subscapular fossa is a landmark of the scapula. As the name implies it is on the deep side of the scapula. The subscapular fossa of the scapula is of functional importance because it is the origin for.
The subscapularis muscle one of the four rotator cuff muscles. Anterior deep view of subscapularis. The subscapular fossa of the scapula is a structural feature on the scapula bone also known as the shoulder blade or shoulder bone.
The subscapular fossa of the scapula bone is. The concave depression fossa shallow depression. The subscapular fossa is a broad concavity on the costal surface of scapula.
The medial two-thirds of the fossa are marked by several oblique ridges which run lateralward and upward. The ridges give attachment to the tendinous insertions and the surfaces between them to the fleshy fibers of the Subscapularis. The lateral third of the fossa is.
Subscapularis is a strong triangular muscle that fills the subscapular fossa of scapula. Lying posterolateral to the thoracic cage it starts as a wide muscle whose medial two-thirds originate from the subscapular fossa of scapula and from several tendinous intramuscular septa at the ridges of the fossa. The remaining fibers arise from an aponeurosis that covers the posterior surface of the.
The subscapular fossa is a landmark of the scapula. As the name implies it is on the deep side of the scapula. The subscapular fossa of the scapula is of functional importance because it is the origin for.
The subscapularis muscle one of the four rotator cuff muscles. No matter how the arm moves the subscapularis fossa remains between the scapula and the chest wall. So the phrase costal surface meaning related to the ribs is a good one.
A a Even in the extreme case of a winged scapula - the fossa remains with the bone and the costal surface remains obvious - even when the terms posterior and anterior are somewhat unhelpful. The scapula has two surfaces. On the anterior aspect is the smooth costal surface which is concave in shape and is majorly taken up by the subscapular 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. Infraspinous fossa of scapula.
Middle facet of greater tubercle. Lateral rotation adduct stabilizes scapula posteriorly. Lateral border of scapula.
Inferior facet of greater tubercle. Lateral rotation adduction stsabilize scapula posteriorly. TA the concave ventral aspect of the body of the scapula giving origin to the subscapularis muscle.
Fossa subscapularis TA Farlex Partner Medical Dictionary. The subscapular fossa is a landmark of the scapula. As the name implies it is on the deep side of the scapula.
The subscapular fossa of the scapula is of functional importance because it is the origin for. Medical Definition of infraspinous. Lying below a spine especially.
Lying below the spine of the scapula. What is the function of a Infraspinous fossa. The subscapularis muscle is one of the four muscles that make up the rotator cuff the others being.
Supraspinatus infraspinatus and teres minor. Subscapular fossa of the scapula. Lesser tubercle of the humerus.
Some fibers also extend to the greater tubercle and bicipital groove. Suprascapular axillary and subscapular arteries 1. It is the anterior surface of the scapula facing the thoracic cage or ribcage.
It has a large concave depression over most of the surface called the subscapular fossa from where the rotator cuff muscle subscapularis originates. This region is marked by some longitudinal ridges out of which a thick ridge joins the lateral border. Subscapular Fossa - this is on the anterior front surface of the shoulder blade.
The subscapularis originates here. Coracoid Process - beak shaped bony prominence on the anterior surface of the scapula serves as the attachment site for several muscles. Infraglenoid Tubercle - bony projection just below the glenoid fossa.
The long head of triceps brachii starts here. The costal or ventral surface of the scapula presents a broad concavity the subscapular fossa. It provides an attachment for the subscapularis muscle.
Lesson1bonesofpostshoulder at The Anatomy Lesson by Wesley Norman Georgetown University SUNY Labs 03os-0103 - Scapular Region. Its also known as the ventral surface or subscapular fossa. It is on the front side of the scapula structure to which the subscapularis muscles are attached.
The medial sides two-thirds of the fossa consist of three longitudinal ridges that are oblique and there is another thick ridge that is present adjoining the lateral border. The anterior surface of the scapula is known as the costal surface. This side of the scapula is relatively unremarkable with a concave depression over most of its surface called the subscapular fossa.
The subscapularis muscle originates from this side. The superolateral surface of the costal scapula is the coracoid process. The supraspinous fossa lodges the supraspinatus muscle.
The infraspinous fossa is occupied by the infraspinatus and the muscular ridges at its lower part are for the origin of teres minor. The costal or ventral surface presents a shallow depression called subscapular fossa which lodges the subscapularis. The subscapular fossa of the scapula faces anteriorly.
The surgical neck is the most frequently fractured part of the humerus. Which of the following is not located anteriorly on the distal end of the humerus. Medical Definition of subscapular fossa.
The concave depression of the anterior surface of the scapula. The subscapular fossa itself has its own angle the subscapular angle depicted above where the bone appears bent on itself as the part of the scapula functioning as the shoulder joint glenoid cavity bends anteriorly to reach the shoulder.
