How do you assess pec minor?
The most common clinical method to assess pectoralis minor length is to mea- sure the distance from the posterolateral angle of the scapula to the examination table of a supine patient, with distances greater than 2.54 cm (1 in) suggesting pectoralis minor tightness.
What muscle is under the latissimus dorsi?
It is bounded above by the trapezius, below by the latissimus dorsi, and laterally by the vertebral border of the scapula; the floor is partly formed by the rhomboideus major.
What is pec minor?
Function. The primary actions of this muscle include the stabilization, depression, abduction or protraction, internal rotation and downward rotation of the scapula. It elevates the ribs for deep inspiration when the pectoral girdle is fixed or elevated.
Is the pectoralis minor deep or superficial?
The pectoralis minor muscle is a small triangular shaped muscle that lies deep to pectoralis major muscle and passes as three muscular slips from the thoracic wall (ribs III to V) to the coracoid process of the scapula. Pectoralis minor draws the scapula forward and downward, and raises the ribs in forced inspiration.
How do you test for tight lats?
The “hands over head” wall test is a simple test for assessing lat stiffness. Have your athlete against a wall, tuck their chin and flatten their back. Next, have them raise their arms overhead. If stiff, their lats will prevent the arms from reaching the top of the wall.
What is the pectoralis minor?
The pectoralis minor lies, for the most part, beneath the pectoralis major, arising from the middle ribs and inserting into (attaching to) the scapula (shoulder blade). It aids in drawing the shoulder forward and downward (in opposition to the trapezius muscle).
How to assess and stretch the pec minor?
Place towel rolls under the elbows and rest forearms on abdomen. Measure the distance from the acromion to the table. Normal is 1” from the table. Excessive is greater than 1” from the table. In the position described above, stretch the pec minor by performing the following:
How to stretch the latissimus dorsi muscle muscle?
Latissimus Dorsi Stretches. Begin this latissimus dorsi stretch standing tall with your back straight and hands above your head. Gently lean to one side until you feel a mild to moderate stretch in the side of your upper back and shoulder (figure 2). Hold for 5 seconds and then return to the starting position.
Where does the pec minor muscle come from?
The pectoralis minor originates on the outer surfaces of ribs 3, 4, and 5 and from the fascia of the intercostal muscles. The muscle inserts on the coracoid process of the scapula.
Where does the blood supply the latissimus dorsi muscle?
The skin covering the latissimus dorsi muscle is supplied by roots T4 to T12, inclusive by both ventral and dorsal rami, as well as the dorsal rami of L1 to L3.
