What divides the scapula into unequal protions?
The scapula is divided by the spine into unequal portions called the supraspinous fossa and infraspinous fossa. The spine is a bony ridge that runs diagonally across the flat surface of the scapula.
What does the scapula look like?
The scapula is a flat, triangular bone located on the back of the shoulder. It has a prominent ridge called the spine that divides it into unequal portions called the supraspinous and infraspinous fossae. The scapula also has a bony projection called the acromion that forms the tip of the shoulder.
What process on the scapula does not articulate with other bone?
The medial border of the scapula is what does not articulate on the scapula with any other bone. It is actually parallel to the vertebrae column and because it does not articulate the arms as well as shoulders have move movement.
Is the greater sciatic notch inferior to the posterior inferior iliac spine?
Yes, the greater sciatic notch is inferior to the posterior inferior iliac spine. The greater sciatic notch is a cavity located on the posterior side of the hip bone, while the posterior inferior iliac spine is a bony projection from the hip bone.
What musel moves scapula?
The scapula is not only moved by one muscle, but several. All the muscles around it that connect to it assist in moving it in a certain way whether it be moving it closer to the spine in adduction, away from the spine in abduction, elevating it, or rotating it. The subscapularis, romboids, trapezius, supraspinatus, infraspinatus, latisimus dorsi, levator scapuli, teres, and some other rotator cuff muscles all move the scapula. -elias

The supraspinosis fossa is located on what bone?
It's called the supraspinous fossa and it's on the scapula.
Where is the lower trapezius insertion located in the human body?
The lower trapezius insertion is located on the spine of the scapula in the human body.
What divides the scapula into two unequal portions?
spine
What are the three fossa of the scapula?
The three fossae of the scapula are the supraspinous fossa, infraspinous fossa, and subscapular fossa. The supraspinous fossa is located above the spine of the scapula and serves as the origin for the supraspinatus muscle. The infraspinous fossa is situated below the spine and provides attachment for the infraspinatus muscle. The subscapular fossa is found on the anterior surface of the scapula and serves as the origin for the subscapularis muscle.
What is the insetion of the trapezius muscle?
Spine of the Scapula Acromion Clavicle
Bone that has an acromion and spine?
The acromion is the part of the scapula or shoulder blade that forms the tip of the shoulder. The acromion is an anatomical feature on the shoulder blade (scapula), together with the coracoid process extending laterally over the shoulder joint.
What is the location of the lower trap insertion in the human body?
The lower trapezius muscle inserts on the spine of the scapula, which is located on the upper back of the human body.
What large bone forms the back part of the shoulder?
scapula
What bone does the spine attach?
the skull, pelvis, ribs, and scapula
What structures are related to lateral end of the spine of the scapula?
Scapula is very interesting bone. It holds the upper limb, but have no bony attachment to your thorax. It is attached to thorax, through the collar bone or the clavicle. Lateral end of the clavicle is attached to the lateral end of the spine of the scapula. On the inside of the spine of the scapula and clavicle, you have insertion of the muscle called as trapezius. From out side of this, you have origin of the deltoid muscle. Technically and mechanically, the trapezius muscle continues as deltoid muscle.
What is the proximal attachment of the infraspinatus?
The proximal attachment of the infraspinatus muscle is primarily located on the infraspinous fossa of the scapula. It originates from the posterior surface of the scapula, below the spine of the scapula, and spans laterally to attach to the greater tubercle of the humerus. This positioning allows it to play a crucial role in shoulder stabilization and external rotation of the arm.
