An acrocentric chromosome is a type of chromosome that has its centromere located near one end, resulting in an asymmetrical shape. Some synonyms for acrocentric chromosome include satellite chromosome, submetacentric chromosome, and telocentric chromosome. Satellite chromosomes are similar to acrocentric chromosomes, but have a small extension called a satellite on one end. Submetacentric chromosomes have centromeres located closer to the middle, making them slightly more symmetrical than acrocentric chromosomes. Telocentric chromosomes have their centromeres located at the very end, resulting in a more elongated shape. All of these terms refer to slight variations of the same basic structure of a chromosome.
