Define body habitus.
classification of human beings into four basic body structure categories which describe the body cavity structure (size, shape, position, tonus, and mobility of internal organs)

Study Notes
Body Habitus Overview
- Body habitus categorizes humans into four body structure types based on the anatomy of internal organs, including their size, shape, position, tonus, and mobility.
Classifications of Body Habitus
- Hypersthenic: Largest body type, accounting for 5% of the population.
- Sthenic: Standard size, most common at 50% of the population.
- Hyposthenic: Intermediate size, making up 35% of the population.
- Asthenic: Smallest body type, comprising 10% of the population.
Hypersthenic Characteristics
- Massive build; organs such as the stomach and gallbladder are positioned high and laterally in the abdominal cavity.
- The colon is high, encircling the abdominal cavity.
- The heart is short and wide with a high diaphragm, creating a long abdominal cavity.
- The stomach typically exceeds its longitudinal axis.
Sthenic Characteristics
- Gallbladder positioned 2-3 inches from the body midline and 4-5 inches above the iliac crest.
- Organs generally found in typical textbook locations.
Hyposthenic Characteristics
- Modified asthenic body type, resembling the sthenic body in structure.
- Gallbladder located 1-2 inches from the midline and 2-3 inches above the iliac crest.
Asthenic Characteristics
- Exhibit a narrow and shallow thorax with ribs sharply sloped, leading to broader lung apices.
- Heart structure appears elongated and narrow, with low diaphragm and short abdominal cavity.
- The stomach is vertical and narrow, resting low and displaying a tortuous appearance.
- Gallbladder sits vertically near midline, right at iliac crest level.
- Colon is positioned low in the abdominal cavity, folding onto itself.
