scapula.
CLASSFICIATION :-
-is one of the seven scapulohumeral muscles.
ORIGIN :-
-lower 1/3 of dorsal surface
of lateral border of the scapula.
INSERTION :-
-medial lip of Bicepital groove of humerus .
NERVE SUPPLY :-
-lower scapular nerve
ACTION :-
- adduction & extension & medially rotation of
the arm

29. TERES MINOR MUSCLE

30. def :-
-is small thin muscle that is located in the
shoulder joint
classification :-
-is one of four muscles that make up the
rotator cuff
origin :-
- upper 2/3 of the lateral border of the
scapula

35. ROTATOR CUFF

36. Def
-Is a group of muscles and tendons that
hold the shoulder joint in place and
allows the arm movement
Component :-
-This group of muscles consist of :
• Supraspinatous muscle
• Infraspinatous muscle
• Teres minor muscle
• Supscapularis muscle
Action :-
-The actions provided by these muscles is
Rotation and elevation of the arm

37. Orienation :-
-These muscles are orientate around
scapula precisely around the glenoid
cavity and insert above the surgical neck
of humerus , This orientation make the
shoulder joint stable :
• Anteriorly by :

• Posteriorly by :
-Infraspinatous
-Teres minor
• Superiorly by :
-Supraspinatous

38. What Is Rotator Cuff Pain?
-Is a damage that occur to the tendons of
the rotator cuff muscles , this damage
can be an injure , inflammation or worn
-Mainly it can caused by :
• Rotator Cuff tendinitis
• Rotator Cuff tendinosis
• Rotator Cuff tears
