Sameer Abid Al-Redah | Amer Hussin
The intent of this study were to explain the gross anatomical study of the bones of the camelfeet (Forelimb and Hindlimb) from under the carpal and tarsal joints by using traditional techniquesfor gross anatomical preparation of bones (using 6 pairs of forelimb and hindlimb). The camel ischaracterized by two contrary adaptive factors, firstly, its camel leg must be long and skinny forprotective from hot desert environment, and secondly, the leg must be strong enough to a bear theheavy weight of the camel body and to prevent sinking in the sands of the desert. The camel leghave these two factors (elongation & slimness) and at the same time the strength stemming from ofseveral structural adaptations such as the abundance of fatty-elastic (digital cushions) inside thefoot, the length of the metacarpal and metatarsal and the horizontal positioning of phalanges. Theresults showed that the large metacarpal and metatarsal bones are characterized by the fusion of 3rdand 4th metacarpal and metatarsal bones on the entire length of the bone except at the distal endwhich happens a divergence of bone from each other larger than the rest of the animals to distributethe weight of the camel on a larger area, metatarsal bone resemble the metacarpal with theexception of the metatarsal being smaller and has more cylindrical body, the bones of the phalangesare longest when compared to other animals, the proximal phalanx of camel was characterized byits elongation when compared with ruminants, the length of the middle phalanx reach to almost halfthe length of the proximal phalanx while the distal phalanx was considered the smallest of the threephalanges and has the wedge shape, the number of sesamoid bones in the camels were differentfrom other animals in the absence of the distal sesamoid bone in order to allow free movement ofthe foot.
