Types

- molecules (Proteins, Lipids, carbohydrates, nucleic acids...)

- cellular organelles (cellular structures)
- cells
- tissular components
- tissues (tissular structures)
- organ components
- organs
- systems
- body

A structure has Functions, that can be normal or pathological (functional anomalies).

A morphological anomaly of a structure is a lesion:

- molecular lesions
- cellular lesions
- tissular lesions
- organ lesions

Lesions can associate in lesional syndromes than can be observed in different diseases.

Each normal structure may be abnormal in pathological conditions:

- structure anomalies
- structure malformations
- structure lesions
- structure diseases
- structure tumors
