∙ 12y ago
The serratus anterior muscle protracts and depresses the scapula. It originates on the upper ribs and inserts along the medial border of the scapula. This muscle is important for stabilizing the scapula during movements like pushing and reaching overhead.

What does the pectoralis do?
The pectoralis major is a large chest muscle that is responsible for flexing, adducting, and internally rotating the arm at the shoulder joint. It also helps to stabilize the shoulder joint during movement.
What is the action of the levator scapulae?
The levator scapulae muscle primarily elevates and rotates the scapula (shoulder blade) downward and inward, allowing for movements such as shrugging the shoulders. It can also contribute to lateral flexion of the neck when acting unilaterally.
Which muscle is responsible for holding the scapula on the chest wall?
The Serratus Anterior muscle is responsible for holding the scapula against the chest wall. It helps stabilize the scapula and is important for proper shoulder movement and function.
Which muscle is located between the scapula and ribcage?
The serratus anterior muscle is located between the scapula and ribcage. It has a serrated ("saw-like") appearance and is responsible for stabilizing the scapula against the ribcage during arm movements.
Is the trapezius a flexor or an extensor?
The trapezius muscle is an extensor muscle. It is responsible for extending and laterally flexing the neck, as well as retracting and elevating the scapula.
Which muscle will depress the scapula or elevate the ribs?
The muscle that depresses the scapula is the lower trapezius, while the muscle that elevates the ribs is the external intercostals.
Type of movement trapezius produces?
The trapezius muscle is responsible for various movements of the shoulder and neck, such as elevation, depression, retraction, and rotation of the scapula. It also helps to extend and laterally flex the neck.
What muscle group is your scapula from?
The scapula is not a muscle; it is a bone.
What does the pectoralis do?
The pectoralis major is a large chest muscle that is responsible for flexing, adducting, and internally rotating the arm at the shoulder joint. It also helps to stabilize the shoulder joint during movement.
What muscles can be antagonistic to themselves?
Trapezius - it elevates and depresses the scapula.
What is the action of the levator scapulae?
The levator scapulae muscle primarily elevates and rotates the scapula (shoulder blade) downward and inward, allowing for movements such as shrugging the shoulders. It can also contribute to lateral flexion of the neck when acting unilaterally.
What is the action of the levitor scapulae muscle?
Raises the scapula at the Scapulothoracic Joint or inclines neck to corresponding side if the scapula is fixed
Which muscle moves the scapula forward?
Serratus Anterior, moves scapula forward.
What muscle tenses the neck and depresses the mandible?
Platysma
What is the action of the serratus anterior muscle?
Abducts scapula (moves scapula away from spinal column)
Which muscle is responsible for holding the scapula on the chest wall?
The Serratus Anterior muscle is responsible for holding the scapula against the chest wall. It helps stabilize the scapula and is important for proper shoulder movement and function.
Does the trapezius contract?
Trapezius muscle- located from the skull through the cervical and thoracic vertebrae to the lateral 1/3 of the clavicle and spine of scapula. Function: Elevates, Depresses, Retracts, and rotates the scapula up and down. Innervated by the Spinal Accessory Nerve
