abstract
The study was conducted on two adult Civet and domestic cat with an aim to study the gross anatomical features of the appendicular skeleton of arm i.e. humerus with a comparative study with domestic cat. The proximal extremity comprised of head, greater and lesser tuberosity with bicipital groove. The shaft was cylindrical at the middle. It has several lines, deltoid tuberosity and brachial groove. Interesting finding is the presence of two numbers of pit in olecranon fossae on each bone along with supra condyloid foramen in the distal extremity in both the species. The head of the humerus of Common palm civet cat was round where as the head of humerus was oval in domestic cat. The supra condyloid foramen and the lateral supra condyloid crest was more developed in civet than the domestic cat. The supracondyloid crest on the lateral surface over the lateral epicondyle was more developed in Common palm civet cat and formed the lower boundary of the brachial groove; but in domestic cat the crest was less developed.
