The Serratus Anterior moves the scapula forward and rotates it upward.
What else can I help you with?
Small rectangular muscle that rotate the glenoid cavity of the scapulae inferiorly?
downward Rotation (Inferior Rotation) Rotary movement of the scapula; moving inferior angle of scapula medially and downward.Levator scapulaeRhomboidsPectoralis minorPectoralis majorLatissimus dorsi
What muscle originates on the anterior surface of the scapula and inserts on the proximal anterior humerus?
The muscle you are referring to is the subscapularis muscle. It originates on the subscapular fossa of the scapula and inserts on the lesser tubercle of the humerus. It is responsible for medial rotation of the shoulder joint.
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
What is subscapularis?
The subscapularis is a muscle located at the front of the shoulder, part of the rotator cuff group. It originates from the subscapular fossa of the scapula and inserts into the lesser tubercle of the humerus. This muscle primarily functions to medially rotate the arm and stabilize the shoulder joint. Its proper function is essential for a range of movements involving the upper limb.
Is the bicep brachii a cardiac muscle?
No. The Biceps Brachii and another muscle called the brachialis bend the elbow. The Biceps Brachii also helps rotate the wrist in the direction called supination and helps to forward flex the shoulder.
Will the pectoralis minor inferiorly or superiorly rotate the scapula?
The pectoralis minor primarily aids in the inferior rotation of the scapula. When it contracts, it pulls the coracoid process of the scapula downward, which contributes to this rotational movement. This action is important for various arm movements, particularly those involving adduction and extension.
What is the action of the external oblique muscle?
they rotate the ribs and pelvis, they help you breathe and they flex your trunk forward
Which way do twin screw props on a boat rotate when propelling the boat forward?
In opposite direction, but they are designed to propel the boat forward even if they rotate in opposite directions.
What is antagonist to the teres minor?
The teres major muscle is considered to be antagonistic to the teres minor muscle. The teres major muscle is a larger muscle located in the upper arm that works to extend, medially rotate, and adduct the arm, while the teres minor muscle is a smaller muscle that works to laterally rotate the arm.
Can the acromion bone bend from the scapular bone?
The acromion is a bony projection of the scapula (shoulder blade) that does not bend; it is a rigid structure. However, the scapula itself can move and rotate, allowing for a range of motion in the shoulder joint. While the acromion itself remains stable, the movements of the scapula can affect its position in relation to the arm and torso during shoulder movements.
Does the sternocleidomastoid rotate to same side?
The sternocleidomastoid muscle primarily rotates the head to the opposite side. When one side of the sternocleidomastoid contracts, it causes rotation of the head towards the opposite side while also tilting it to the same side. However, if both sides contract together, they flex the neck forward. Thus, the muscle does not rotate the head to the same side; that action is performed by other muscles.
When a car dirves off a cliff why does it rotate forward as it falls?
When a car drives off a cliff, often one end of the vehicle drops first and the weight distribution changes, causing the car to rotate forward as it falls. This is due to the force of gravity acting on the car's center of mass, pulling it downward and causing it to tip forward.
