Central retinal artery: The blood vessel that carries blood into the eye and supplies nutrition to the retina.
The counterpart to the central retinal artery is the central retinal vein, the vessel that carries blood away from the retina.

- Central venous line
Central venous line: A catheter (tube) that is passed through a vein to end up in the thoracic (chest) portion of the vena cava (the large vein returning blood to the heart) or in the right atrium of the heart. Central venous lines have a number of different uses. A central venous line allows concentrated […]
- Central vision
Central vision: A process in which millions of cells change light into nerve signals that tell the brain what the person is seeing. As a person reads, drives, and performs other activities that require fine, sharp, straight-ahead vision, light is focused onto the macula in the center of the retina, the light-sensitive layer of tissue […]
- Centric-fusion translocation
Centric-fusion translocation: A type of chromosome rearrangement, also called a Robertsonian translocation, in which there is fusion of an entire long arm of one acrocentric chromosome with a similarly intact long arm of another acrocentric chromosome. The short arms of the chromosomes participating in the translocation are usually lost. Acrocentric chromosomes have their centromere near […]
Centromere: The ‘waist’ of the chromosome that is essential for the division and retention of the chromosome in the cell. The centromere is a uniquely specialized region of the chromosome to which spindle fibers attach during cell division.
