Upper Limbs
How many bones are in phalanges? (fingers and thumb)
14
How many bones are in metacarpals? (palm)
5
How many bones are in carpals? (wrist)
8
What are the most distal bones of the hand?
phalanges
Each finger and thumb are called?
a digit
Fingers 2,3,4, and 5 is composed of three phalanges called
proximal, middle, and distal
The thumb has two phalanges called
proximal and distal
The second group of bones of the hand, which make up the palm
metacarpals
What three parts is the metacarpal composed of
head, body, and base
What four main groups does the upper limb consist of
hand and wrist, forearm, arm, and shoulder girdle
The joint between the two thumb phalanges
interphalangeal (IP) joint
The metacarpals that articulate with the phalanges at their distal ends
metacarpophalangeal (MCP) joints
The metacarpals articulate with the respective carpals called
carpometacarpal (CMC) joints
The third group of bones of the hand and wrist
carpals
Beginning on the lateral, or thumb, side
scaphoid
The correct term for the tarsal bone of the foot
the navicular
The correct term for the carpal bone of the wrist
the scaphoid
The third carpal
triquetrum
The smallest of the carpal bones
pisiform
The second carpal in the proximal row
lunate
The largest of carpal bones
capitate
The last carpal in the distal row on the medial aspect
hamate
Hooklike process, which projects from its palmar surface
hamulus
The wedge-shaped, also four sided, is the smallest bone in distal row
trapezoid
A small depression on the medial aspect of the distal radius
ulnar notch
Located near the wrist at the distal end of the ulna
head of the ulna
Located at the proximal end of the radius near the elbow joint
head of the radius
The long midportion of both of the radius and the ulna
body
The rough oval process on the medial and anterior side of the radius, just distal to the neck
radial tuberosity
The two beaklike processes of the proximal ulna
olecranon, and the coronoid process
The medial margin of the coronoid process opposite the radial notch
coronoid tubercle
The large concave depression, or notch, that articulates with the distal humerous
trochlear notch
The small, shallow depression located on the lateral aspect of the proximal ulna
radial notch
The body of the humerus is the long center section, and the expanded distal end of the humerus
humeral condyle
The articular portion of the humeral condyle is divided into two parts
trochlea and capitulum
Shaped like a pulley or spool
trochlea
Has two rimlike outer margins and a smooth depressed center portion called
trochlear sulcus
Meaning “little head”
capitulum
The small projection on the lateral aspect of the distal humerus above the capitulum
lateral epicondyle
What has specific depressions on both anterior and posterior surfaces
distal humerus
The two shallow anterior depressions
coronoid fossa and radial fossa
The deep posterior depression of the distal humerus
olecranon fossa
All joints of the upper limb are classified as
synovial freely moveable, and diarthrodial.
Beginning distally with the phalanges, all IP joints are
ginglymus
The first CMC joint of the thumb is a
saddle
The second through fifth CMC joints are
plane
The wrist joint is a what type of joint
ellipsoidal
The two types of fat stripes
scaphoid and pronator
The three type of fat pads
anterior, posterior, supinator
Inflammation of the bursae or fluid-filled sacs that enclose the joints
bursitis
