Q

What is the Origin, Insertion, Innervation, Course and Action of the Sternocleidomastoid?

A

Origin: mastoid process of temporal bone of the skull

Insertion: superior end of manubrium of sternum adn superior surace of sternal end of clavicle

Innervation: Accessory CN XI

Course: fibers run downward medially and anteriorly

Action: INHALATION, muscle for deep breathing (accessory), raises sternum and clavicle during deep breathing, Rotate the head contralaterally and downward

Q

What is the Origin, Insertion and Job of the scalenes

A

Origin: transverse process of C2-C7, upper cervicla vertebrae

Insertion: anterior; 1st rib, medial 1st rib, posterior 2nd rib (at the tubercle)

Job: elevate Ribs 1 and 2

Q

What is the Origin, insertion, and motion of pectoralis major?

A

Origin: entire length of the sternum, some cartilage of the sternal portion of the clavicle ventrally

Insertion: scapula (cracoid process)

Movement: upward and a little bit laterally –> if scapula is fixated, when muscle (pectoralis minor) contracts then it lifts the ribs

Q

What is the origin and insertion of serratus anterior

A

origin: ribs 1-9 on the lateral side

Insertion: scapula, the vertebral boarder, when the scapula is stabilized the serratus anterior contracts and pulls the ribs ou tand upward, measure of last resort for dep breathing (inhalation, supplemental)

Q

Describe the Trapezius

A

spinous processes of cervical and thoracic vertebrae up and laterally to the acromium process of the scapulae and clavicle

17
Q

What are the anterior thoracic muscles of inspiration?

A

external intercostals

internal intercostals

18
Q

What are the posterior throacic muscles of inspiration?

A

levator costarum (brevis and longus)

serratus posterior superior

19
Q

What are the accessory muscles of the neck for inspiration?

When are these muscles used?

A

sternoclidomastoid

scalenes

These muscles are used if the primary muscles of inspiration are not working however, they are not very effective

20
Q

What are the Musclces of the Upper arem and Shoulder for inspiration?

A

Pectoralis Major

Pectoralis Minor

Serratus Anterior

21
Q

What are the muscles that stabalize the scapulae?

A

Levator scapulae

Rhomboideus major

Rhomboideus minor

Trapezius
