Final answer:
Acellular cementum is found on the root of a tooth, particularly at the cervical half closest to the crown, and helps anchor the tooth within the jaw bone.
Step-by-step explanation:
The acellular cementum is a bone-like tissue found on the root of a tooth. It covers the dentin in the root and is crucial for anchoring the tooth in the jaw bone. It works in tandem with the periodontal ligament, a key component of the specialized fibrous joint known as a gomphosis, which holds the tooth securely within its bony socket in either the maxilla or mandible. Unlike alveolar cementum, which can contain cells, acellular cementum does not contain cells and is typically found at the cervical half of the root, which is the area closest to the crown of the tooth.
