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).
Cephalic index viewed from above the head. The cephalic index or cranial index is a number obtained by taking the maximum width (biparietal diameter or BPD, side to side) of the head of an organism, multiplying it by 100 and then dividing it by their maximum length (occipitofrontal diameter or OFD, front to back).
Medical ultrasound includes diagnostic techniques (mainly imaging techniques) using ultrasound, as well as therapeutic applications of ultrasound. In diagnosis, it is used to create an image of internal body structures such as tendons, muscles, joints, blood vessels, and internal organs, to measure some characteristics (e.g., distances and velocities) or to generate an informative audible sound.
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).
Ultrasound cephalometry is useful for determining baby growth in utero. Cephalometry can also determine if an unborn child will pass through the birth canal. Certain 3D imaging applications are now used in obstetric cephalometry. In 1961, Donald and Brown employed ultrasound technique for measurement of the fetal head.
The reflected ultrasound is received by the probe, transformed into an electric impulse as voltage, and sent to the engine for signal processing and conversion to an image on the screen. The depth reached by the ultrasound beam is dependent on the frequency of the probe used. The higher the frequency, the lesser the depth reached. [9]
Hajdu–Cheney syndrome causes many issues with an individual's connective tissues. Some general characteristics of an individual with Hajdu–Cheney syndrome include bone flexibility and deformities, short stature, delayed acquisition of speech and motor skills, dolichocephalic skull, Wormian bone, small maxilla, hypoplastic frontal sinuses, basilar impression, joint laxity, bulbous finger ...
Dolichocephalic — long-headed; Mesaticephalic — medium-headed; Brachycephalic — short-headed [14] The vertical cephalic index refers to the ratio between the height of the head multiplied by 100 and divided by the length of the head. Humans may be: Chamaecranic — low-skulled; Orthocranic — medium high-skulled; Hypsicranic — high-skulled
