junctional epithelium

This detailed cross-sectional diagram illustrates the comprehensive anatomy of a tooth, clearly distinguishing between the crown (visible portion above the gumline) and root (embedded portion below the gumline). Each labeled component plays a critical role in maintaining dental health and function, from the hard protective enamel covering the crown to the complex neurovascular network supplying the tooth and surrounding structures.

This detailed anatomical illustration depicts the key structures that comprise the periodontium, including the gingival tissue, periodontal ligament fibers, cementum, and alveolar bone. Together, these specialized tissues form a functional unit that anchors teeth within the jaw while allowing for minute movements during mastication and absorbing occlusal forces.
