Segmentation

Segmentation (Medicine)

Segmentation (pronunciation: /sɛɡmɛnˈteɪʃən/) is a term used in various fields of medicine to describe the division or separation of something into segments. The term is derived from the Latin segmentum, meaning "a piece cut off", and the suffix -ation, indicating an action or process.

In Anatomy

In anatomy, segmentation refers to the division of an organ or body part into segments. For example, the spinal cord is divided into segments, each of which is responsible for innervating a specific part of the body. Similarly, the liver is divided into segments, each of which has its own blood supply and biliary drainage.

In Radiology

In radiology, segmentation is a process used in image analysis where an image is divided into regions, or segments, that have similar attributes. For example, in a CT scan of the lung, segmentation can be used to separate the lung tissue from the surrounding air and tissues.

In Genetics

In genetics, segmentation refers to the process by which a fertilized egg divides into segments, or blastomeres, during early embryonic development. This process is crucial for the formation of the body plan of the organism.

In Pathology

In pathology, segmentation can refer to the division of a disease process into stages or phases. For example, the progression of cancer can be segmented into stages based on the extent of the disease.
