Which Muscles Elevates The Scapula Quizlet Anatomy And Physiology?

Which muscle will elevate the scapula?

The levator scapulae muscle originates from the transverse processes of the cervical vertebra and descends to attach to the superior (uppermost) and medial (near the midline) corner of the scapula. This muscle elevates the scapula.

Which muscle adducts and elevates the scapula?

The trapezius has three portions: the superior part elevates the scapula, the middle part retracts the scapula, and the inferior part depresses the scapula while lowering the shoulder. Latissimus dorsi: This V-shaped muscle covers much of the thoracic wall below the trapezius.

What muscle and or muscles elevate depress retract and protract the scapula?

Function. The rhomboid major helps to hold the scapula (and thus the upper limb) onto the ribcage. Other muscles that perform this function include the serratus anterior and pectoralis minor. Both rhomboids (major and minor) also act to retract the scapula, pulling it towards the vertebral column.

What is the action of the indicated muscle elevates Scapulae and rotates it downward?

Action: abducts scapula and rotates it downward. RMA: Elevates third through fifth ribs during forced inhalation when scapula is fixed. Insertion: vertebral border of inferior angle of scapula.

What is the function of scapula?

The scapula is an important bone in the function of the shoulder joint. It engages in 6 types of motion, which allow for full-functional upper extremity movement including protraction, retraction, elevation, depression, upward rotation, and downward rotation.

How does the scapula attach to the body?

The scapula has three processes: the acromion, the spine, and the coracoid process. Muscle attachments to these landmarks are covered in the “Muscles” section. The ventral surface of the scapula abuts the thoracic rib cage and has a large concavity called the subscapular fossa where the subscapularis attaches.

What muscle extends and adducts the arm?

The thick and flat teres major is inferior to the teres minor and extends the arm, and assists in adduction and medial rotation of it. The long teres minor laterally rotates and extends the arm. Finally, the coracobrachialis flexes and adducts the arm.

Which muscles enable you to shrug your shoulders?

The trapezius muscle is a postural and active movement muscle, used to tilt and turn the head and neck, shrug, steady the shoulders, and twist the arms. The trapezius elevates, depresses, rotates, and retracts the scapula, or shoulder blade.

What muscle pulls scapula down?

The rhomboids are rhombus-shaped and are used to pull the shoulder blades together. They also rotate the scapula in a downward direction and provide stability for your shoulders. These five exercises help strengthen the rhomboid muscles and improve your posture.

How do you retract the scapula?

Scapular Exercise: Retraction

  1. Put the band around a solid object, such as a bedpost, at about waist level.
  2. With your elbows at your sides and bent to 90 degrees, pull the band back to move your shoulder blades toward each other.
  3. Repeat 8 to 12 times.

Which of the following actions can scapular stabilizers perform?

The scapular stabilizers provide strength, stability and prevent impingement. Impingement is simply when the shoulder joint or glenohumeral joint hits the top of the scapula (acromium) causing pain, inflammation and, if left untreated, muscle tears.

Which group of muscle flexes and rotates the neck?

Spinal Muscles: A Comprehensive Guide

CERVICAL MUSCLES FUNCTION NERVE
Sternocleidomastoid Extends & rotates head, flexes vertebral column C2, C3
Scalenus Flexes & rotates neck Lower cervical
Spinalis Cervicis Extends & rotates head Middle/lower cervical
Spinalis Capitus Extends & rotates head Middle/lower cervical

What is the largest muscle group of the back?

The widest muscle in your body is the latissimus dorsi, also known as your lats. Your latissimus dorsi have a fan-like shape. They originate in the lower and middle portion of your back and attach on the inner aspect of your humerus (upper arm bone).

What is the origin insertion and action of muscles?

Conventionally, a muscle origin describes the attachment of a muscle on the more stable bone. The insertion then, is the attachment of a muscle on the more moveable bone. The action of the muscle describes what happens when the more mobile bone is brought toward the more stable bone during a muscular contraction.
