Infraspinatus insertion and origin. Things To Know About Infraspinatus insertion and origin.

The supraspinatus is a relatively small muscle which is located in the upper shoulder region. The supraspinatus muscle is one of the four rotator cuff muscles, which also include: the infraspinatus, teres minor, and subscapularis muscles. A useful mnemonic to remember these muscles is “SITS” [1] [2]. Occupying the supraspinous fossa of the ...The infraspinatus sits in the infraspinatus fossa, while teres minor sits slightly inferiorly to it. The odd one out in this group is the subscapularis muscle we spoke about earlier in the "muscles that position the shoulder" grouping; it instead inserts on the lesser tuberosity or tubercle. ...
