(20) This forms a living interposition material between the acromion and the greater tuberosity of the humerus, forming a real "three-bellies" muscle resisting the ascent of the humeral head.
Deltoid
Definition:
(a.) Shaped like the Greek / (delta); delta-shaped; triangular.

(3) This approach was used in 42 shoulders with rotator cuff tears or posterior instability without complications of infection, failure of deltoid healing, or compromise of suprascapular or axillary nerves.
(4) There was a high correlation between the percentage of type I fibers and the citrate synthase activity within the vastus lateralis (r = .760) and deltoid (r = .610) (P less than 0.05) but not the gastrocnemius (r = .200).
(5) Deltoid muscle biopsy documented scattered basophilic regenerating myofibers and focal atrophic fibers with focal increases of endomysial connective tissue, small endomysial foci of inflammatory cells, and occasional perimysial, perivenular lymphocytic infiltrates.

(7) At least eight centimeters of the posterior aspect of the proximal region of the humeral diaphyseal cortex can be exposed through the interval between the lateral head of the triceps and the deltoid muscle.
(8) The deltoid muscles of the same patients had a rather even mixture of type I and II fibers.
(9) Two cases of winged scapulae due to fibrosis of the deltoid muscle are reported.
(10) The size of the peaks led to estimates of the underlying excitatory postsynaptic potentials (EPSP) amplitude of 5.5 mV for the deltoid and 2.2 mV for the pectoralis motor units.
(11) Signal amplitude increased in the trapezius, the deltoid and the infraspinatus, but was constant in the biceps brachii.
(12) A lightweight fiberglass spica has proven to be useful after repair of the deltoid origin, repair of complete rupture of the rotator cuff, and shoulder arthrodesis.
(13) The electromyograms produced by the prime mover muscles (sternal portion of pectoralis major, anterior deltoid, long head of triceps brachii) achieved maximal activation at the commencement of the ascent phase of the lift and maintained this level essentially unchanged throughout the upward movement of the bar.
(14) A decrement of the proximal muscles at rest was demonstrated in 116 (80%) of the patients and the deltoid muscle was most sensitive.
