What is the primary action of the rhomboids?
Table of Contents
The main action of the rhomboid muscles is scapular retraction around the scapulothoracic joint. Scapular retraction is a simultaneous sliding of the scapula superiorly and medially along the trunk. This superomedial movement of the scapula rotates the glenoid cavity inferiorly, dropping the shoulder girdle.
What muscle group is the rhomboids in?
The rhomboids are a collective group of muscles formed by the rhomboid major and minor. The rhomboids are important in upper limb movement and stability of both the shoulder girdle and scapula. Both rhomboids receive innervation from the dorsal scapular nerve and supplied by the dorsal scapular artery.
What exercise works the rhomboids?
What exercises work the rhomboids specifically? As discussed above, rows and pulldowns (or pull ups) will target the rhomboids effectively so long as you squeeze your shoulder blades together at the end of the concentric phase of the motion. However, this is not the only way to target your rhomboids.
Are the rhomboids and antagonist?
The rhomboid major: agonistic: latissimus dorsi, lower trapezius, middle trapezius, teres minor, posterior deltoid. antagonistic: anterior deltoid, middle deltoid, pectoralis major, pectoralis minor, infraspinatus, levator scapulae.
What does serratus anterior do?
When the shoulder girdle is fixed, all three parts of the serratus anterior muscle work together to lift the ribs, assisting with respiration. The serratus anterior, also known as the “boxer’s muscle,” is largely responsible for the protraction of the scapula, a movement that occurs when throwing a punch.
Are rhomboids under trapezius?
The rhomboid muscles, located on your upper back underneath the trapezius muscle, play a big part when it comes to posture. This is especially true if you have overdeveloped chest muscles or your shoulders pronate forward. The rhomboids are rhombus-shaped and are used to pull the shoulder blades together.
Which of the following is an action of the rhomboid minor?
Together with the rhomboid major, the rhomboid minor retracts the scapula when trapezius is contracted. Acting as a synergist to the trapezius, the rhomboid major and minor elevate the medial border of the scapula medially and upward, working in tandem with the levator scapulae muscle to rotate the scapulae downward.
What causes rhomboid strain?
A rhomboid muscle strain or spasm is usually caused by overuse of your shoulder and arm. This can happen from: Overhead activities, like serving a tennis ball or reaching to put objects on a high shelf. Rowing.
What is the action of the rhomboid major muscle?
The main action of the rhomboid major muscle is to retract and elevate the inner border of the scapula. When you pinched your shoulder blades together during the physical assessment test at the beginning of this lesson, that motion is termed a scapular retraction. The rhomboid major also rotates the outer part of the scapula downward.
What are the rhomboids?
The rhomboids are considered to be part of a group of muscles that make up the superficial musculature of the upper back (along with trapezius, latissimus dorsi, and levator scapulae ). As a group, these muscles function to connect the upper limbs to the trunk, as opposed to the rotator cuff muscles that attach the upper limbs to the scapula.
Is the rhomboid muscle extrinsic?
Together with trapezius, levator scapulae and latissimus dorsi, they comprise the superficial layer of the extrinsic back muscles. The rhomboid muscles extend between the nuchal ligament, spinous processes of thoracic vertebrae and scapula.
Where does the rhomboid major attach to the spine?
Rhomboid Major: Insertion. The rhomboid major muscle inserts on the scapula, the official name for the shoulder blade. Specifically, this muscle attaches to the inside border just below the spine of the scapula. The spine is a ridge that runs across the top of the scapula.
