What are the 4 types of body habitus? | Sthenic, Hyposthenic, Asthenic, Hypersthenic |
What percentage of people do each body habitus make up? | Sthenic - 50% Hyposthenic - 35% Asthenic - 10% Hypersthenic - 5% |
Sthenic organ placement: Heart Lungs Diaphragm Stomach Colon Gallbladder | Heart: Moderately transverse Lungs: Moderate length Diaphragm: Moderately high Stomach: High, upper left Colon: Spread evenly; slight dip in transverse colon Gallbladder: Centered on right side, upper abdomen |
Sthenic Characteristics: Build Abdomen Thorax Pelvis | Build: Moderately heavy Abdomen: Moderately long Thorax: Moderately short, broad, and deep Pelvis: Relatively small |
Asthenic Organ placement: Heart Lungs Diaphragm Stomach Colon Gallbladder | Heart: Nearly vertical and at midline Lungs: Long, apices above clavicles, may be broader above base Diaphragm: Low Stomach: Low and medial, in the pelvis when standing Colon: low, folds on itself Gallbladder: Low and nearer the midline |
Asthenic Characteristics: Build Abdomen Thorax Pelvis | Build: Frail Abdomen: Short Thorax: Long, shallow Pelvis; Wide |
Hyposthenic Organ placement and Characteristics | Organs and characteristics for this habitus are intermediate between sthenic and asthenic body habitus types; this habitus is the most difficult to classify. |
Hypersthenic Organ placement: Heart Lungs Diaphragm Stomach Colon Gallbladder | Heart: Axis nearly transverse Lungs: Short, apices at or near clavicles Diaphragm: High Stomach: High, transverse, and in the middle Colon: Around periphery of abdomen Gallbladder: High, outside, lies more parallel |
Hypersthenic Characteristics: Build Abdomen Thorax Pelvis | Build: Massive Abdomen: Long Thorax: Short, broad, and deep Pelvis: Narrow |
