Dolichocephalic dogs (such as the Lurcher or German Shepherd) have elongated noses. This makes them vulnerable to fungal diseases of the nose such as aspergillosis. [1] In humans the anterior–posterior diameter (length) of dolichocephaly head is more than the transverse diameter (width). [citation needed]
A mesaticephalic skull is of intermediate length and width. Mesaticephalic skulls are not markedly brachycephalic or dolichocephalic. When dealing with animals, especially dogs, the more appropriate and commonly used term is not "mesocephalic", but rather "mesaticephalic", which is a ratio of head to nasal cavity.
The dolichocephalic skull is narrow at base yet long in length, so the Alaunt could be referred to as a modified dolichocephalic breed, as mesocephalic is a balance of base to length. Moreover, the Alaunt or mastiff must be separated from the Molossoides in head study, as this term does not separate the Mastiff from the mountain dogs or even ...
Swedish professor of anatomy Anders Retzius (1796–1860) first used the cephalic index in physical anthropology to classify ancient human remains found in Europe. He classified brains into three main categories, "dolichocephalic" (from the Ancient Greek kephalê, head, and dolikhos, long and thin), "brachycephalic" (short and broad) and "mesocephalic" (intermediate length and width).
The cephalic index of a vertebrate is the ratio between the width (side to side) and length (front to back) of its cranium (skull). This ratio does not concern the muzzle or face, and thus is distinct from the craniofacial ratio, which compares the size of the cranium to the length of the muzzle.
Brachycephaly (derived from the Ancient Greek βραχύς, 'short' and κεφαλή, 'head') is the shape of a skull shorter than average in its species.It is perceived as a cosmetically desirable trait in some domesticated dog and cat breeds, notably the pug and Persian, and can be normal or abnormal in other animal species.
Palatal view of a Sthenurus sp. skull. S. stirlingi had a large, dolichocephalic skull with a more elevated braincase position and an inflamed nasal frontal region in comparison to the contemporaneous skull of S. tindelai. [13] S. andersoni skull fossils show a dome-like forehead that is unique to it among other dolichocephalic sthenurines ...
The Russian-born French anthropologist Joseph Deniker initially proposed "nordique" (meaning 'northern') as an "ethnic group" (a term that he coined).He defined nordique by a set of physical characteristics: the concurrence of somewhat wavy hair, light eyes, reddish skin, tall stature and a dolichocephalic skull.
