[Ultrastructural aspects of the submandibular gland]

Area of Science:

• Histology
• Cell Biology
• Anatomy

Context:

• The human submandibular gland is a major salivary gland with complex cellular architecture.
• Understanding its fine structure is crucial for diagnosing and treating salivary gland disorders.

Purpose:

• To elucidate the ultrastructural organization of normal human submandibular glands.
• To describe the morphology of secretory cells, myoepithelial cells, and ductal structures.
• To examine the innervation of the submandibular gland.

Summary:

• Electron microscopy revealed secretory cells organized around a lumen, enveloped by myoepithelial cells with tapering processes.
• Intercalated and striated ducts were identified, with striated duct cells featuring basal membrane infoldings and aligned mitochondria.
• The study also included an examination of the submandibular gland's nerve supply.

Impact:

• Provides detailed ultrastructural insights into normal human submandibular gland morphology.
• Establishes a baseline for comparative studies in pathological conditions.
• Contributes to the understanding of salivary gland function and innervation.
