2. ÅPPËÑDÏÇÜLÅR SKËLËTÅL SÝSTËM (126 BØÑËS)
01
BØÑËS ØF FØRË LÏMBS (30 X 2 = 60)
Include Humerus (1), Radius (1), Ulna (1), Carpals
(wrist bones- 8), Metacarpals (palm bones-5)
& Phalanges (digits-14).
02
BØÑËS ØF HÏÑD LÏMBS (30 X 2 = 60)
Include Femur (thigh bone- 1), Patella (knee
cap- 1), Tibia (1) & fibula (1), Tarsals (ankle
bones-7),
Metatarsals
(5)
&
Phalanges
(digits-14).
Ç. PËÇTØRÅL GÏRDLËS (2X2 = 4)
Include clavicle (2) & scapula (2).
Scapula is a large triangular flat bone
situated in the dorsal part of the thorax
between the second and 7th ribs.
Scapula
(shoulder
blade)
has
a
slightly elevated ridge (spine) which
projects as a flat, expanded process
(acromion). The clavicle (collarbone)
articulates with this.
(AIPMT 2005)
Below the acromion is glenoid cavity
which articulates with the head of
humerus to form the shoulder joint.
D. PËLVÏÇ GÏRDLËS (2)
Formed of 2 coxal bones. Each coxal bone is formed by the fusion of 3
bones- Ilium, Ischium & pubis.
At the point of fusion of ilium, ischium and pubis is a cavity (acetabulum)
to which the thigh bone articulates.
The 2 halves of the pelvic girdle meet ventrally to form pubic symphysis
containing fibrous cartilage.
