deltoid

Examples of deltoid in the following topics:

• Muscles of the Shoulder

  • Deltoid – The deltoid muscle is a triangular muscle which covers the shoulder.
  • Produced by the biceps brachii (both heads), pectoralis major, anterior deltoid, and corocobrachialis.
  • Produced by the supraspinatus and deltoid.
  • Produced by contraction of subscapularis, pectoralis major, latissimus dorsi, teres major, and anterior deltoid.
  • Highlighted in orange, the deltoids cover the rounding of the shoulder joint.

• Humerus (The Upper Arm)

  • A major feature of the shaft is the deltoid tuberosity located laterally to which the deltoid muscle attaches.
  • The deltoid, corocobrachialis, brachialis, and brachioradialis muscles attach to the anterior surface, with the triceps brachii attaching to the posterior.

• Clavicle

  • Laterally the deltoid muscle originates from the anterior surface and the trapezius muscle attaches to the posterior surface at the trapezoid line.
  • Muscle attachment sites (pectoralis major, subclavius muscle, deltoid, and sterno-hyoid) are highlighted.

• Intramuscular Injections

  • Intramuscular injections are often given in the deltoid, vastus lateralis muscles and the ventrogluteal and dorsogluteal areas .

• Scapula

  • It is divided by a ridge-like structure called the spine of the scapula, from which the deltoid and trapezius muscles originate.

• Arches of the Feet

  • The ligament is strengthened medially by blending with the deltoid ligament of the ankle joint, and is supported inferiorly by the tendon of the tibialis posterior, which is spread out in a fan-shaped insertion and prevents undue tension of the ligament or such an amount of stretching as would permanently elongate it.
