Here are the diagrams of the histological structure of enamel from the medical library:

Histological Structure of Enamel

Figure 1 - Cross-section of an Incisor Tooth (Overall Anatomy)

(Histology: A Text and Atlas with Correlated Cell and Molecular Biology)

Diagram of incisor tooth cross-section showing enamel and surrounding structures

This diagram shows the full tooth in section, labeling the enamel (outermost layer of the crown), lines of Retzius, dentin with dentinal tubules, interglobular spaces, odontoblasts, pulp chamber, cementoenamel junction, noncellular and cellular cementum, alveolar bone, and apical foramen. The enamel covers the anatomic and clinical crown, ending at the cementoenamel junction.

Figure 2 - Basic Organization of Enamel Rods (Prisms)

(Histology: A Text and Atlas with Correlated Cell and Molecular Biology, Fig. 16.10)

3D diagram of enamel rod organization showing keyhole shape, head, tail, and dimensions

This 3D diagram shows the keyhole-shaped enamel rods (prisms):

Each rod is 4 µm wide and 8 µm tall, with the head oriented superiorly and the tail pointing inferiorly
Rods span the full thickness of the enamel (~2,000 µm / 2 mm rod length)
Hydroxyapatite crystals run parallel to the long axis in the head, and more obliquely in the tail

Figure 3 - Ameloblasts and Enamel (Histological Micrographs)

(Junqueira's Basic Histology - Text and Atlas, 17e, Fig. 15-9)

Histological micrographs: (a) H&E section of embryonic tooth bud showing ameloblasts, enamel, and dentin; (b) Ground tooth preparation showing enamel rods and incremental lines

(a) H&E section (×400): Shows ameloblasts (A) - tall, polarized secretory cells - adjacent to the enamel layer (E), which contacts dentin (D). Connective tissue (CT) lies on the basal side.
(b) Ground preparation (×400, unstained): Fine dentinal tubules visible in dentin (D), and faint enamel rods (arrows) in the enamel (E), with diagonal incremental growth lines (lines of Retzius) crossing the enamel.

Key histological points about enamel:

Hardest substance in the body; 96-98% calcium hydroxyapatite
Acellular - once formed, it cannot regenerate
Organized into enamel rods (prisms) spanning the full thickness from the dentinoenamel junction to the surface
Incremental growth lines = lines of Retzius (rhythmic growth bands)
Secreted by ameloblasts, which disappear after tooth eruption
