Directions

• The first slide asks a question.

• The second slide answers the question.

• Use these slides like flash cards to test your core knowledge.


Question

• What is the superior attachment of the trapezius muscle?


Answer

•The occipital bone• More specifically, the external occipital protuberance

and the superior nuchal line


Question

• What ligament attaches the superior trapezius to the spinous processes of the cervical vertebrae?


Answer

•The ligamentum nuchae• This ligament sticks out posteriorly from the spinous

processes of the cervical vertebrae.


Question

• Which vertebrae does the trapezius attach to?


Answer

• The spinous processes of all cervical and all thoracic vertebrae (C1 through T12).


Question

• What bones of the shoulder girdle does the trapezius muscle attach to?


Answer

• Scapula– The points on the scapula that the traps

attach to are the spine of the scapula and the acromion process.

• Clavicle– The trapezius muscle inserts as a continuous

line from the scapula to the lateral third of the clavicle.


Question

• What bony landmark is the vertebral attachment site for the trapezius muscle?

a. Transverse process

b. The lamina

c. The spinous process

d. The pedicle


Answer

a. Transverse process

b. The lamina

c.The spinous processd. The pedicle

The spinous process is the bony spike that grows directly posteriorly and at the midline of the posterior portion of the vertebra. It is the part that looks like the ridges that stick out of the backs of lizards.


Question

• Which fibers of the trapezius are most responsible for retraction of the scapula?

a. Upper fibers

b. Middle fibers

c. Lower fibers


Answer

a. Upper fibers

b.Middle fibersc. Lower fibers

The middle fibers of the trapezius originate at the upper 5 thoracic vertebrae, and insert at the spine of the scapula, and the acromion process. The horizontal alignment of these fibers allows for retraction of the scapula.


Question

• Which Vertebrae have attachment sites for the rhomboid muscles?

a. C7-T5

b. T5-T10

c. T10-L2

d. L2-L5


Answer

a.C7-T5b. T5-T10c. T10-L2d. L2-L5

• Rhomboid minor originates at C7 and T1, and is superior to rhomboid major.

• Rhomboid major originates at T2-T5.


Question

• What are the actions of the rhomboid muscles?


Answer

• Retract the scapula

• Elevate the scapula

• Downward rotation of the scapula (causing the glenoid fossa to face inferiorly)


Question

• What is the origin of the levator scapula muscle?

a. Upper 4 cervical vertebrae

b. Lower 4 cervical vertebrae

c. The occipital bone

d. The temporal bone


Answer

a. Upper 4 cervical vertebraeb. Lower 4 cervical vertebrae

c. The occipital bone

d. The temporal bone


Question

• What is the action of the levator scapula muscle?


Answer

• Elevation of the scapula

• Downward rotation of the scapula

• Lateral flexion and ipsilateral rotation of the cervical vertebrae


Question

• What is the origin of the serratus anterior muscle?


Answer

• Upper 9 ribs


Question

• What is the action of the serratus anterior muscle?


Answer

• Protraction of the scapula– This is motion of the scapula laterally and

anteriorly. – The serratus anterior also plays an important

role in holding the scapula close to the posterior ribcage.


Question

• What bone connects the scapula to the axial skeleton?


Answer

• Clavicle


Question

• Which muscle lies superficially to the pectoralis minor?

a. Pectoralis major

b. Serratus anterior

c. Coracobrachialis

d. Brachioradialis


Answer

a.Pectoralis majorb. Serratus anterior

c. Coracobrachialis

d. Brachioradialis


Question

• What is the insertion of the pectoralis major?


Answer

• The lateral lip of the bicipital groove.– The bicipital groove is also referred to as the

intertubercular sulcis. This landmark is where the tendon for the long head of the biceps brachii lies. It is between the lesser tubercle and greater tubercle of the humerus.


Question

– Humerus– Sternum– Clavicle– Scapula

— Ribs— Coracoid process— Cervical vertebrae— Ulna

What are the origins for the pectoralis major? (Choose three of the options below.)


Answer

• Sternum

• Clavicle

• Ribs


Question

What is the origin of the pectoralis minor? a. Sternum

b. Clavicle

c. Coracoid process

d. Ribs


Answer

a. Sternumb. Claviclec. Coracoid process

d. Ribs

– The origin of the smaller pec muscle, pectoralis minor, is at ribs 3, 4, and 5.


Question

• Which of the teres muscles medially rotates the arm at the shoulder?


Answer

Teres major


Question

What muscle has the same action as teres major? a. Teres minor

b. Pectoralis major

c. Latissimus dorsi

d. Deltoids


Answer

• Teres minor• Pectoralis major

• Latissimus dorsi• Deltoids

– This little muscle, teres major, is nicknamed “lat’s little helper,” as it does the same action as its much larger counterpart, the latissimus dorsi.


Question

• What rotator cuff muscle causes the first 15° of abduction of the humerus at the shoulder?


Answer

• Supraspinatus


Question

Put these body parts in order of most superficial to most deep. – Ribs– Scapula– Subscapularis– Infraspinatus– Serratus anterior


Answer

– Infraspinatus– Scapula– Subscapularis– Serratus anterior– Ribs


Question

• What are the four muscles of the rotator cuff? Hint: This group of muscles is often referred to as the SITS muscles.


Answer

• Supraspinatus

• Infraspinatus

• Teres minor

• Subscapularis


Question

• What muscle of the rotator cuff has an action of medial rotation of the humerus at the shoulder?


Answer

• Subscapularis


Question

• What three muscles attach at the coracoid process?


Answer

• Pectoralis minor

• The short head of the biceps brachii

• Coracobrachialis


Question

• What muscle can flex, extend, and abduct the humerus at the shoulder?


Answer

• The deltoid– This shoulder muscle has three heads, each with its

own set of actions.– The heads are:

• Anterior• Middle• Posterior
