Simple Cuboidal Epithelium

• Simple CUBOIDAL Epithelium: lines various DUCTS of GLANDS and ORGANS, where it COVER the surface for STURDINESS and PROTECTION.
• Simple CUBOIDAL Epithelium: for SECRETION
• Cells are as what as they are WIDE?

  Tall
• Describe the NUCLEUS of Simple CUBOIDAL Epithelium?

  Large, spherical, and central
• The GREATER THICKNESS OF Simple CUBOIDAL Epithelium, allows what organelles to be rich in MITOCHONDRIA and other organelles for high level of WHAT across the EPITHELIUM?

  Cytoplasm and active transport
• Simple CUBOIDAL Epithelium can be found where?

  Excretory ducts of different organs
• Proximal convoluted tubules: brush border of MICROVILLI
• Microvilli: small, nonmotile projections that cover the surfaces of absorptive cells
• What cells store THRYOGLOBULIN in the follicles for subsequent use in production and endocrine secretion of T3 (thyroxin) and T4?

  Follicular cells
• Parafollicular cells or C cells produce calcitonin, which is found in the MIDDLE THIRD or lateral lobes of the THYROID.
• The secretory part of the SCALP is lined with what?

  Simple cuboidal epithelium
• The DUCTS of SCALP are lined with what?

  Stratified cuboidal epithelium
• Intercalated DUCTS: receive secretions from ACINI. They have flattened cuboidal epithelium that extends up into the lumen of the acinus to form what are called centroacinar cells.
• INTRALOBULAR DUCTS: have a classical cuboidal epithelium and are seen within LOBULES. They receive secretions from intercalated ducts.
• INTERLOBULAR DUCTS: are found between lobules, within the connective tissue septae. They vary considerably in size. The smaller forms have a cuboidal epithelium, while a columnar epithelium lines the larger ducts. This transmit secretions from intralobular ducts to the MAJOR PANCREATIC DUCT
