greater tubercle of the humerous
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.
There are more than one: The deltoid, supraspinatus, infraspinatus, teres major and minor and the subscapularis.
The supraspinatus muscle contains mostly type I (slow-twitch) muscle fibers, which are more fatigue-resistant and used for sustained contractions. The infraspinatus muscle contains a mix of type I and type II (fast-twitch) muscle fibers, which are used for more powerful and quick contractions.
The term that identifies the site where a muscle attaches to the bone it pulls on is called the "insertion." This is typically the more movable attachment of the muscle, as opposed to the origin which is the less movable attachment site.
To place the insertion point inside a cell in a spreadsheet, simply click on the cell where you want the insertion point to appear. The insertion point will show up as a blinking cursor inside the cell, allowing you to enter or edit text or data directly within the cell.

yes
The two attachment points are the origin and insertion. The origin is the immovable (or slightly moveable point. The insertion is the movable point. The insertion always moves towards the origin.
The name of that is acupuncture. :)
1- Supraspinatus and its function is to abduct the arm ,and it's innervated by the Suprascapular nerve. 2- Infraspinatus muscle and its function is to externally rotate the arm ,and it's innervated by the Suprascapular nerve. 3- Teres minor muscle and its function is to externally rotate the arm ,and it's innervated by the Axillary nerve. 4- Subscapularis muscle and its function is to internally rotate the humerus ,and it's innervated by the Upper and Lower subscapular nerve.
the answer isD. Infraspinatus
insertion point
The Infraspinatus is one of the four rotator cuff muscles in the shoulder that helps to stabilize and rotate the arm. A tendon is where the muscle attaches to bone. Tendinopathy is a general term meaning injury or disease to a tendon. So Infraspinatus tendinopathy would mean some kind of damage or disease to the Infraspinatus muscle near the area where it attaches to the bone.
