Summary
This study introduces a novel method for automatically extracting anatomical functions from existing biomedical ontologies. This approach enables the creation of a comprehensive anatomical function ontology, linking structures to their roles.
Area of Science:
- Bioinformatics
- Ontology Engineering
- Computational Biology
Background:
- Existing biomedical ontologies lack coverage of anatomical functions.
- Current anatomy ontologies do not explicitly link anatomical structures to their functions.
- This limits accurate class definitions in anatomy and phenotype ontologies.
Purpose of the Study:
- To develop an ontology of anatomical functions.
- To establish explicit relations between anatomical structures and their functions.
- To improve the accuracy of anatomy and phenotype ontologies.
Main Methods:
- Ontological analysis of functions and functional abnormalities.
- Automatic extraction of anatomical functions using natural language processing, graph-based analysis, and formal inferences.
- Introduction of a new relation to link material objects to their functional processes.
Main Results:
- An approach for automatic extraction of anatomical functions was developed.
- A new relation was introduced to link anatomical structures to processes.
- The study provides a framework for an ontology of anatomical functions.
Conclusions:
- A skeleton for an ontology of anatomical functions can be automatically extracted from existing ontologies.
- Limitations in current ontologies hinder complete representation of anatomical functions and abnormalities.
- Further work is needed to ensure consistent and complete ontological representation.

01:20Anatomical Terminology
Knowledge of anatomy is essential to understand human biology and medicine. Anatomists and health care professionals use standard terminology to describe the human body with more precision and no ambiguity. Anatomical terms have mostly Greek and Latin-derived roots. Because these languages are rarely used in conversation, the meaning of words remains the same. Each term is made up of a root in between the prefixes and suffixes. The root of a term often refers to an organ, tissue, or condition,...
01:24Overview of Anatomy and Physiology
Human anatomy is the scientific study of the body's structures. Some of these structures are very small and can only be observed and analyzed with the assistance of a microscope. Other larger structures can readily be seen, manipulated, measured, and weighed. The word "anatomy" comes from a Greek root that means "to cut apart." Human anatomy was first studied by observing the body's exterior and the wounds of soldiers and other injuries. Later, physicians were allowed to dissect the bodies of...
01:09Functional Classification of Joints
Functional Classification of Joints
The functional classification of joints is determined by the amount of mobility between the adjacent bones. Joints are functionally classified as a synarthrosis or immobile joint, an amphiarthrosis or slightly moveable joint, or as a diarthrosis, a freely moveable joint. Fibrous and cartilaginous joints can be functionally classified as either synarthroses or amphiarthroses, whereas all synovial joints are classified as diarthroses.

01:12Regional Terms
Regional terms describe anatomy by dividing the body parts into different regions that contain structures involved in contributing similar functions. Using these terms helps increase the accurate description and identification of the particular region of interest or region affected by the disease.
Primarily, the human body has two major regions, the axial and appendicular regions. The axial region comprises regions from the head to the abdomen and makes up the central body axis. In contrast,...

01:18Structural Organization of the Human Body: An Overview
It is convenient to consider the body's structures in terms of fundamental levels of organization that increase in complexity: subatomic particles, atoms, molecules, organelles, cells, tissues, organs, organ systems, and organisms.
To study the chemical level of organization, scientists consider the simplest building blocks of matter: subatomic particles, atoms, and molecules. All matter in the universe is composed of one or more unique pure substances called elements, familiar examples of...

00:51Anatomical Movements
Anatomical movements refer to the various actions or motions that can be performed by the body's joints and muscles. These movements are described using specific terms to provide a standardized way of discussing and understanding the range of motion at different joints.
Here are some common anatomical movements:
Flexion and extension motions are in the sagittal (anterior–posterior) plane of motion. These movements take place at the shoulder, hip, elbow, knee, wrist, metacarpophalangeal,...
