Pre Lab Sauderland Flashcards
What is this: the lateral portion of the scapular region, where the scapular joins with the clavicle and the humerus and where the region is covered by the rounded mass of the deltoid muscle
shoulder
What muscles make up the rotator cuff?
subscapularis
infraspinatus
teres minor
supraspinatus
What is unusual about the coracoacromial ligament?
it goes from one part of the scapular to another!
What are these symptoms of: Shoulder pain and tenderness, especially when reaching overhead, reaching to the back, lifting, sleeping on affected side Shoulder weakness Loss of shoulder range of motion Inclination to keep shoulder inactive
rotator cuff injury
What are the causes of rotator cuff injury?
Tendinitis (often due to overuse or overload)
Bursitis (irritation, inflammation, and attrition of supraspinatus tendon and wall of subacromial bursa
What are risk factors of rotator cuff injury?
age (over 40)
being an athlete
construction worker
poor posture and weak shoulder muscles
How do you fix a rotator cuff via surgery?
surgical acromioplasty
subacromial bursectomy
rotator cuff reconstruction
What is this:
tendons become entrapped under the acromian; compression, injury, rotator cuff tendonitis
rotator cuff impingement syndrome
A rotator cuff injury with attrition (wearing away by friction or rubbing) of the supraspinatus tendon, results in (blank)
degenerative tendonitis
Where is there a potential space at the axillary area?
between the rib and the serratus anterior
Where is the serratus anterior attached to the scapula?
at the medial border
How can you tell someone has serratus anterior paralysis?
you have winged (protruding) scapula on affected side
Injuries to the (blank) will affect the important function of the serratus anterior muscle. The muscle can no longer protract the scapula or abduct the arm completely.
long thoracic nerve
How do you damage the LT nerve?
it runs vertical and superficial so it can be stabbed, or crushed or screwed up surgery (construction workers get it a lot)
Where is the basilic vein?
where is the cephalic vein?
Why are these important?
near the pinky side of the forearm (ulnar)
near the thumb side of the forearm (radial) and lies between the groove of the deltoid and pectoralis major
This is where you draw blood and inject things into.
Why do they call the cephalic vein the cephalic vein?
because it runs high up towards the encephaly (brain)
What does the cephalic vein run through?
it runs through the costocoracoid membrane (investing fasciae for pectoralis major and minor) and joins with axillary vein
What are the lymph nodes in the arm (wrist towards upper arm)?
cubital nodes-> lateral axillary nodes-> deltopectoral nodes
Are the lymph nodes in the hand?
no
lymphatics surround the (blank) vein and the (blank) nerve
axillary vein
long thoracic
Lymphatic drainage on the left side is through the (blank)
thoracic duct
What makes this happen:
sternocleidomastoid pulls medial end of clavicle up, gravity pulls lateral end of clavicle down. Pectoralis major pulls humerus medially and underneath the fractured ends of the clavicle.
fracture of the clavicle
What is this:
Fracture results from fall on the point of the shoulder. Three (3) rotator cuff muscles
remain attached to the torn-off greater tubercle. The subscapularis, that remains
attached to the lesser tubercle of the humerus, pulls the limb into medial rotation.
avulsion fracture of the greater tubercle of the humerus
(blank) attach to greater and lesser tubercle of the humerus. Intertubercular groove is the attachment site for (blank)
Rotator cuff tendons
biceps brachii tendon
What should you be worried about if you have shaft fracture?
the radial nerve :(
What should you be worried about if you have fracture at the distal end of the humerus?
median nerve
the (blank) nerve is vulnerable near the medial epicondyle so you should be worried about this nerve if you had a fracture here.
ulnar
What kind of fracture is this:
lateral pull of deltoid, upward pull of bicep
transverse fracture of shaft of humerus
What is the chief extensor of the forearm?
triceps brachii
The triceps brachii is distally
attached to the (blank)
of the ulna
olecranon
Fracture-separation of the (blank) is common in children
because of frequent falls
distal radial epiphysis
If you have a fall on your hand, which forearm bone will be affected?
The injury will then be transmitted to whichforearm bone once you get close to the elbow?
radius
ulna
A complete transverse fracture of the distal 2 cm of the radius is called a (blank).
It is the most common fracture of the forearm, particularly in adults over 50 and in women with osteoporosis
Colles fracture
What is scapula Steal syndrome?
where blood is stolen from scapula to supply the brachial artery
If there is a subclavian artery occulsion proximal to origin of vertebral artery: the subclavian artery steals arterial blood from the (blank),causing symptoms (dizziness, unsteadiness, vertigo, visual changes, ischemia of upper limb, difference in right and left radial pulse, intermittend claudication [attacks of lameness and pain] in upper limb)
basilar artery
