Body Habitus and Types of Skull

Three Types of Skull
1. Brachycephalic - short broad and shallow head, petrous ridges form a 45 degree angle with the MSP.
2. Mesocephalic - average or normal. Its petrous portions lie at 47 degree angle with the MSP.
3. Dolichocephalic - long, narrow and deep head, petrous portions form a 40 degree angle.
Body Habitus
1. Sthenic - athletic build, average, similar to hypersthenic but modified by elongation of abdomen and thorax.
2. Hypersthenic - body is large and heavy, bony framework is thick, short and wide, lungs and heart are high, transverse stomach and peripheral colon
3. Asthenic - body is slender and light, bony framework is delicate, long narrow thorax, very low long stomach, low medial redundant colon.
4. Hyposthenic - somewhat slighter, less robust, similar to asthenic but stomach, intestines and gallbladder are situated higher in abdomen.
• Sthenic and hyposthenic- more average
• Hypershtenic and asthenic- extreme
