enthesis (plural: entheses) is the connective tissue between tendon or ligament and bone. [1 ]
There are two types of entheses:
Fibrous entheses and fibrocartilaginous entheses.
In a fibrous enthesis, the collagenous tendon or ligament directly attaches to the bone, whereas the fibrocartilaginous interface encompasses four transition zones:
Tendinous area displaying longitudinally oriented fibroblasts and a parallel arrangement of collagen fibres
Fibrocartilaginous region of variable thickness where the structure of the cells changes to
chondrocytes Abrupt transition from cartilaginous to
calcified fibrocartilage—the so-called 'tidemark' or 'blue line' Bone
