Study Notes
Body Habitus Overview
- Body habitus refers to common variations in human body shapes.
- It directly influences the anatomical location of key organs such as the heart, lungs, diaphragm, stomach, colon, and gallbladder.
Types of Body Habitus
- Four primary types with approximate population frequencies:
- Sthenic: 50%
- Hyposthenic: 35%
- Asthenic: 10%
- Hypersthenic: 5%
- 85% of individuals fall under sthenic or hyposthenic classifications, representing the average body frame and organ positioning.
Sthenic Body Habitus
- Constitutes 50% of the population.
- Organ positioning:
- Heart: Moderately transverse
- Lungs: Moderate length
- Diaphragm: Moderately high
- Stomach: Positioned high, upper left
- Colon: Even distribution with slight dip in transverse section
- Gallbladder: Centered on the right side, upper abdomen
Hyposthenic Body Habitus
- Represents 35% of the population.
- Characteristics are intermediate between sthenic and asthenic types.
- This category poses classification challenges due to its variability.
Asthenic Body Habitus
- Accounts for 10% of individuals.
- Organ positioning:
- Heart: Nearly vertical and aligned with the midline
- Lungs: Long with apices above clavicles, broader at the base
- Diaphragm: Positioned low
- Stomach: Low, medial, often basal in the pelvis when standing
- Colon: Loosely folded and positioned low
- Gallbladder: Low and nearer to the midline
Asthenic Characteristics
- Build: Generally frail
- Abdomen: Short in length
- Thorax: Long and shallow
- Pelvis: Wide structure
Hypersthenic Body Habitus
- Comprises 5% of the population.
- Organ positioning:
- Heart: Axis nearly transverse
- Lungs: Short, apices positioned near the clavicles
- Diaphragm: High elevation
- Stomach: High, transverse orientation in the mid-abdomen
- Colon: Encircles the periphery of the abdomen
- Gallbladder: High placement, lying more parallel to body midline
Hypersthenic Characteristics
- Build: Massive structure
- Abdomen: Long in length
- Thorax: Short, broad, and deep
- Pelvis: Narrow build
Sthenic Characteristics
- Build: Moderately heavy
- Abdomen: Moderately lengthy
- Thorax: Moderately short, broad, and deep
- Pelvis: Relatively smaller in proportion
