ABSTRACT
Goodarzi N., Skeletal morphology of forelimb of Paraechinus Hypomelas
(Brandt, 1836); a radiographic and 3D computed tomographic study, Onl J Vet Res., 22 (10):1003-1013, 2018. Author describes forelimb
of the hedgehog Paraechinus Hypomelas (Brandt, 1836) by anatomy, radiography,
computed tomography (CT) and colored prototypes, compared with Paraechinus micropus (Blyth,
1846) and Hemiechinus auritus (S.G.
Gmelin, 1770). The thoracic girdle consisted of a scapula
and clavicle with a pronounced acromion extending as a meta-cromion
hamate process caudally. The supratrochlear
foramen was incomplete and closed by an osseous membrane. Carpal bones
were arranged in proximal rows with intermediate, ulnar and accessory carpals
caudally and a distal row of 4 carpal bones. The first and fifth digits had
proximal and distal phalanges, while other digits had proximal, middle and
distal phalanges. Each digit had a pair proximal sesamoid bones
on the metacarpophalangeal joint and a single distal sesamoid bones on the
distal interphalangeal joint. The findings suggest that the forelimb skeleton
in Paraechinus Hypomelas shows characteristics specific for
fossorial habits with evidence of poor borrowing characteristics.
