Main muscles
Synergistic muscles
Stabilizers
Deltoid Muscle
Deltoideus Muscle
🔹 The deltoid muscle is one of the most important and voluminous muscles of the shoulder region. Its primary function is to move the arm in various directions and stabilize the shoulder joint. Due to its triangular shape, it is named “deltoid,” derived from the Greek word “Δέλτα” (delta), meaning triangle.
🔹 The deltoid muscle is divided into three distinct heads, each playing a specific role in shoulder movement. The anterior head assists in forward motions and arm flexion, the middle head is responsible for abduction and lifting the arm, and the posterior head supports extension and movements behind the body. This muscle is essential for the stability and strength of the shoulder joint, and its weakness can lead to limited range of motion, reduced shoulder power, and an increased risk of injury.
✅ Persian Name: Deltoeid
✅ Latin Name: Deltoideus
✅ Common Name: Shoulder Muscle
✅ Location:
🟡 A superficial muscle located at the top of the upper arm, covering the shoulder joint.
🟡 It forms a cap-like structure over the shoulder joint.
🟡 It directly overlays the head of the humerus and originates from the clavicle, scapula, and the upper part of the arm.
✅ 🔹 Origin
✔ Anterior part: from the outer surface of the clavicle
✔ Middle part: from the acromion, a portion of the scapula
✔ Posterior part: from the spine of the scapula
✅ 🔹 Insertion
✔ All parts of the deltoid muscle insert onto the deltoid tuberosity of the humerus.
✅ 🔹 Function
📌 The deltoid muscle is divided into three parts, each with a specific function:
1️⃣ Anterior Head
- ✔ Moving the arm forward (shoulder flexion)
- ✔ Internal rotation of the arm
- ✔ Assists in horizontal adduction of the arm (moving the arm forward across the body)
2️⃣ Middle Head
- ✔ Lifting the arm outward (shoulder abduction)
- ✔ Assists in stabilizing the shoulder during arm elevation
3️⃣ Posterior Head
- ✔ Moving the arm backward (shoulder extension)
- ✔ External rotation of the arm
- ✔ Assists in horizontal abduction of the arm (moving the arm backward across the body)
📌 Function Summary: The deltoid muscle plays a key role in all shoulder movements and is one of the primary muscles responsible for moving the arm in various directions.
✅ 💪🏻 Muscle Fiber Types
✔ The deltoid muscle consists of a combination of fiber types. ✔ A combination of slow-twitch fibers (Type I) and fast-twitch fibers (Type II). ✔ It is composed of both fiber types.
✔ The anterior and posterior heads contain more fast-twitch fibers, which are suited for powerful and rapid movements.
✔ The middle head has a higher proportion of slow-twitch fibers, which help maintain muscular endurance during sustained activity.

✅ 🏌🏻♂️ Interaction with Other Muscles and Joints
✔ Works closely with the rotator cuff muscles, back muscles, and pectoralis major.
✔ Weakness in this muscle can lead to excessive strain on the shoulder and scapular joints, increasing the risk of injury.
✅ 💉 Vulnerability and Potential Issues
✔ One of the most injury-prone muscles in bodybuilding and strength sports due to its crucial role in heavy movements.
✔ Common injuries include tears, strains, tendon inflammation, and cramps—often caused by improper use of heavy weights.

Supraspinatus Muscle
Supraspinatus Muscle
🔹 The supraspinatus muscle is one of the four main rotator cuff muscles and plays a vital role in stabilizing the glenohumeral (shoulder) joint. It is especially important in initiating arm abduction before the middle deltoid activates. Additionally, it helps prevent shoulder dislocation and enhances joint stability.
🔹 The supraspinatus muscle is often undertrained in daily workouts, but its weakness is one of the most common causes of shoulder pain and injuries such as shoulder impingement syndrome. Therefore, athletes and bodybuilders should pay special attention to strengthening this muscle.
