Anatomy

The study of the form and structure of the human body and its parts.

Cadaver Dissection

The cutting and separation of tissues to reveal their relationships.

Comparative Anatomy

The study of more than one species to examine structural similarities and differences.

Exploratory Surgery

The surgical procedure of opening the body to look inside.

Gross Anatomy

The study of structures that can be seen with the naked eye.

Cytology

The study of structure and function of cells.

Histology

The examination of tissues at the microscopic level.

Ultrastructure

The view of molecular detail under an electron microscope.

Reductionism

The theory that a complex system can be understood by studying its simpler components.

Holism

The idea that whole organisms exhibit properties that cannot be understood solely from their parts.

Homeostasis

The body's ability to maintain stable internal conditions despite external changes.

Negative Feedback

A process where the body senses a change and activates mechanisms to reverse it.

Positive Feedback

A self-amplifying cycle that leads to greater change in the same direction.

Evolution

Changes in organisms over time, resulting from mutations and natural selection.

Anatomical Variation

Differences in anatomical structures among individuals.

Organ Systems

Groups of organs that work together to perform complex functions.

Cell Theory

The theory stating that all structure and function result from the activity of cells.

Hierarchy of Complexity

The organization of biological structures from cells to organisms.
