What Muscle Is Under The Shoulder Blade?

by | Jan 1, 2023 | Uncategorized | 0 comments

The subscapularis muscle is under the shoulder blade. If you define “under” as sitting on the “inner” surface of the shoulder blade. 

Muscles that are below, inferior, or more towards your buttocks would be the latissimus muscle. 

Here’s an article going over the complete anatomy of the musculature and other structures surrounding the shoulder blade.

What is the function of the subscapularis muscle?

The subscapularis is a rotator cuff muscle that internally rotates the humerus and also produces a compressive force on the humeral head, causing it to stay more securely placed in the glenoid (shoulder socket). 

What is the function of the latissimus muscle?

The latissimus muscle is a large muscle that’s primary actions are shoulder extension from a flexed position, shoulder internal rotation, and scapular depression. 

This muscle group is a primary mover during pull-ups and other types of pulling exercises.
