Quiz 5 Flashcards
Bones of the shoulder gridle
sternum, clavicle, scapula
where do the ribs attach
some of them attach to the thoracic vertebrae and the sternum
how many parts does the sternum have
3
Clavicle
connects medially to the sternum, it is slightly S shaped and is commonly called the collar bone
true ribs
any rib that attaches from the vertebra to sternum
floating rib
do not attach in the front, ribs 11 and 12
The scapula
triangularly shaped with 3 angles and borders
bony landmarks of the scapula
spine of the scapula, acromion process, glenoid fossa, coracoid process
what joint in the shoulder girdle is non movable
the acromio-scapular joint
sternoclavicular joint
where the actions of the shoulder girdle occur
actions of the scapula
elevation and depression, adduction and abduction, upward and downward rotation, forward tilt and return from forward tilt
the humerus bony landmarks
head, necks, greater tubercle, lesser tubercle, bicipital grove, and deltoid tuberosity
Shoulder joint structure
ball and socket joint, there is more movement potential than the hip
what is considered a muscle dependent joint
the shoulder joint because ligaments provide minimal support
actions of the shoulder joint on the sagittal plane
flexion and extension
actions of the shoulder joint on the frontal plane
abduction and adduction
actions of the shoulder joint on the transverse plane
inward and outward rotation
Arm Circles in the Sagittal plane
extension - arm swings backward from sides
flexion - arm swings forward from sides
Arm circles in the frontal plane
abduction - arm swings away/out first
adduction - arm swing in/towards first
Positions of the shoulder in the S plane
flexion - arm in front of body
complete flexion - arms straight up
extension - arms down by side
hyperextension - elbow behind shoulder
Bones of the lower arm
ulna and radius
what side is the radius on
the thumb
what side is the ulna on
the little finger side
Proximal articulation (radio-ulnar joints) is between?
the head of the radius and the radial notch of the ulna
distal articulation (radio-ulnar joints) is between?
the head of the ulna with the ulnar notch of the radius
Elbow joint primary articulation point
humerus and ulna
elbow joint secondary articulation point
humerus and radius
actions of the elbow joint on the sagittal plane
flexion and extension
positions of the elbow joint sagittal plane
extension (= 180 degrees)
flexion (less than 180 degrees)
