How Do You Spell MUSCULUS INFRASPINATUS?

1. The musculus infraspinatus, also known as the infraspinatus muscle, is a large and powerful muscle located in the posterior (back) region of the shoulder. It is one of the four muscles that make up the rotator cuff, a group of muscles responsible for stabilizing and controlling the movement of the shoulder joint.

   The infraspinatus muscle originates from the infraspinous fossa, a depression on the posterior aspect of the scapula (shoulder blade). It then wraps around the back of the shoulder and attaches to the greater tubercle of the humerus (upper arm bone). The muscle is situated deep beneath several other muscles, which provide it with protection and support.

   Functionally, the musculus infraspinatus plays a crucial role in the movement and stability of the shoulder joint. Its primary action is to rotate the arm externally, meaning it aids in turning the forearm and hand away from the body. Additionally, it helps to stabilize the shoulder joint during various shoulder movements, especially when the arm is raised or rotated.

   Injury or strain to the infraspinatus muscle can cause pain, weakness, and limited range of motion in the shoulder. Rehabilitation exercises, such as stretching and strengthening exercises, are commonly prescribed to help restore the muscle's function and alleviate symptoms. Sports that involve repetitive overhead motions, such as swimming or throwing, may increase the risk of infraspinatus muscle injuries.

2. Origin, infraspinous fossa of scapuia: insertion, middle facet of great tuberosity of humerus; nerve supply, suprascapular from 5th and 6th carvical; action, draws arm backward and rotates outward.

Common Misspellings for MUSCULUS INFRASPINATUS

The word "musculus infraspinatus" has Latin origins.

The term "musculus" comes from the Latin word "mūsculus", which means "muscle". It is derived from the Latin word "mūs", meaning "mouse", which refers to the shape of a muscle when it contracts.

The word "infraspinatus" is made up of two Latin components. "Infra" means "below" or "beneath", and "spinatus" refers to "the spine". Therefore, "infraspinatus" can be translated to "below the spine". This term describes the location of the muscle, as it is located beneath the spine of the scapula (shoulder blade).
