RAD ANA UPPER LIMB Flashcards
an ellipsoidal (condyloid)-type joint and is the
most freely movable
wrist joint is
radius articulates directly
with two carpal bones which are
scaphoid alng lunate
This wrist
joint is called the
radiocarpal joint.
triquetral bone is also part of the wrist joint in that it is
opposite the
articular disk.
is part of the total
wrist articulation, including a joint between the distal radius and
ulna of the forearm
articular disk
The total wrist joint is enclosed by an articular ______
synovial capsule
attached to the styloid process of the ulna
and fans out to attach to the triquetrum and the pisiform.
ulnar
collateral ligament
extends from the styloid process of the radius
primarily to the lateral side of the scaphoid (
radial
collateral ligament
other five ligament on the wrist
- Dorsal radiocarpal ligament
- Palmar radiocarpal ligament
- Triangular fibrocartilage complex (TFCC)
- Scapholunate ligament
- Lunotriquetral ligament
what classification of joint is the elbow joint
synovial or diarthrodial,
ginglymus
what is the joint that is considered as part of the elbow joint
proximal radioulnar joint
second group of upper limb bones consists of
radius and ulna
The radius and ulna articulate with
each other at the ____ and____
proximal and distal
radioulnar joint
a small conical projection located at
the extreme distal ends of both the radius and the ulna
styloid process
a small depression on the medial aspect of
the distal radius.
ulnar notch
located at the proximal end of the
radius near the elbow joint.
head of the radius
located near the wrist at the distal end
of the ulna.
head of the uln
the shorter of the two bones of the fore
radius
The long midportion of both the radius
and the ulna is called the
body (shaft).
longer of the two bones of the forearm
ulna
two beaklike
processes of the proximal ulna are
olecranon and the
coronoid processes
The medial margin of the coronoid process opposite the radial
notch (lateral) is commonly referred to as the
coronoid tubercle
The small, shallow depression located on the lateral aspect
of the proximal ulna is the
radial notch
The large concave depression, or notch, that articulates with the
distal humerus is the
trochlear notch
the expanded distal end of the humerus
humeral condyle
is shaped like a pulley or spool;
trochlea
humeral condyle is divided into two
trochlea and capitulum
smooth depressed center
portion of troclea
trochlear sulcus
capitulum means
little head
2 epicondyle
lateral and medial
is the small projection on the lateral
aspect of the distal humerus above the capitulum
lateral epicondyle
is larger and more prominent than the lateral epicondyle
and is located on the medial edge of the distal humeru
medial epicondyle
both anterior
and posterior surfaces. The two
radial and coronoid fossa
The deep posterior depression of the distal humerus is the
olecranon fossa
good criterion by which to evaluate a true lateral position of
the elbow when it is flexed
90°
is the largest and longest bone of the upper lim
humerus
The first and smallest arc
trochlear sulcus
the length of humerus on and adult equals to
one-fifth of body height.
The humerus articulates with the
scapula
most proximal part of the humerus is the
head
the slightly constricted area below the head is called
anatomic neck
where did the most common fracture on the humerus happen
surgical neck
what do you call to the deep groove between the 2 tubercles
intertubercular groove
The roughened raised triangular elevation
along the anterolateral surface of the body
deltoid tuberosity
ulnar deviation
projection is commonly known as
special scaphoid project
that opens and best demonstrates the
carpals on the opposite,
Radial deviation
The forearm routinely should be radiographed in what position
AP (hand supinated)
The shoulder girdle consists of two bones:
clavicle and the
scapula
function of the clavicle and scapula
connect each
upper limb to the trunk or axial skeleton.
what is the level of the upper and lower margin of the scapula respectively?
T2 and T7
flat triangular bone with three borders, three
angles, and two surfaces.
scapula
three borders of scapula
medial, superior and lateral
medical term for armpit
axilla
the border nearest the axilla
lateral (axillary) border
the uppermost margin of the scapula
superior border
long edge or border near the vertebrae
medial (vertebral)
border
The lateral angle, sometimes called the
head of the scapula
is the thickest part and ends laterally in a shallow depression
head of the scapula
the shallow depression of lateral angle is called
glenoid cavity
The humeral head articulates with the glenoid cavity of the
scapula to form the
scapulohumeral joint
The constricted area between the head and the body of the
scapula
neck.
thin, flat,
lower part of the body of scapula sometimes is referred to as
wing of scapula
is a long, curved process that extends laterally
over the head of the humerus
acromion
anterior surface of the scapula
costal surface
The middle area of the costal surface presents a
large concavity or depression
subscapular fossa.
a thick,
beaklike process that projects anteriorly beneath the clavicle.
coracoid process
a smooth triangular area
and continues laterally to end at the
acromion.
Three joints or articulations are involved in the shoulder
sternoclavicular joint, acromioclavicular joint, and scapulohumeral
joint
what are the 27 bones of the hand and wrist
- Phalanges (fingers and thumb) 14
- Metacarpals (palm) 5
- Carpals (wrist) 8
The three shoulder girdle joints (articulations) classified as
synovial
joints
movement type of scapulohumeral joint
spheroidal(ball and socket) flexion, extension, ab and adduction, medial and lateral, and circumduction
which constitute the digits (fingers and thumb).
phalanges
consists of the bones of the wrist
carpals
four fingers (digits 2, 3, 4, and 5) is composed of
three phalanges—
phalanges—proximal, middle, and distal
Each phalanx consists of three parts
head, body, base
a boat-shaped bone, is the largest bone in the
proximal row
scaphoid,
(moon-shaped) is the second carpal in the proximal
lunate
distinguished by its pyramidal shape
and anterior articulation with the small pisiform
triquetrum
(pea-shaped), the smallest of the
carpal bones,
pisiform
a four-sided, irregularly shaped
bone that is located medial and distal to the scaphoid and proximal
to the first metacarpal
trapezium
the smallest bone in the distal row
trapezoid
the largest of the carpal bones
