Infraspinatus
The infraspinatus muscle is one of the four muscles that make up the rotator cuff, located on the posterior side of the shoulder blade (scapula). It plays a crucial role in the stability and mobility of the shoulder joint by enabling external rotation of the arm and assisting in shoulder stabilization during dynamic movements.
Tibialis Anterior
The tibialis anterior muscle is a key muscle located in the front of the lower leg that plays a vital role in ankle dorsiflexion and stabilizing the foot during walking, running, and other movements.
Brachialis
The brachialis muscle is a strong, flat muscle located in the upper arm. It is considered a pure elbow flexor because its action is not affected by the position of the forearm or wrist.
Piriformis
The piriformis muscle is a flat, band-like muscle located in the buttocks near the top of the hip joint.
Quadratus Lumborum
Quadratus Lumborum is considered a postural muscle group and part of the core muscles.
Pectoralis Minor
The pectoralis minor is a small muscle that stabilizes the shoulder blade and aids in scapular movement and breathing.
Triceps Brachii
The triceps brachii, or triceps, is a large, thick muscle in the upper arm that’s responsible for extending the elbow joint. It’s located on the back of the upper arm, between the shoulder and the elbow, and often appears horseshoe-shaped.
Soleus
The soleus is a muscle in the lower leg that runs from below the knee to the heel, primarily responsible for plantarflexion, where the foot is pointed downward.
Latissimus Dorsi
The Latissimus Dorsi muscle, often referred to as the “lats,” is a large, flat muscle on the back that stretches to the sides, behind the arm, and is partly covered by the trapezius on the back near the midline.
