Reticular Fibers, Tendon, Elastic Lamina, and Adipose Tissue

Reticular Fibers

  • A: Reticular Fibers serve as a supporting framework for many highly cellular organs such as lymph nodes, endocrine glands and the liver (Wheaters)

    This slide is lymphatic tissue that has an expansive network of reticular fibers.
  • A: Reticular fibers


  • A: Regularly arranged tightly packed collagen fibers. DCCTRA

    B: Thin outer layer of synovium
  • A: Fibroblasts

    B: Regularly arranged collagen fibers
  • A: Fibroblasts

Elastic Lamina

  • A: Internal elastic lamina is a connective tissue layer just beneath the endothelium. This layer functions to accommodate volume fluctuations in the arteries of the body. The lamina is DECTIRA during diastole and DECTRA during systole because the contraction of the heart causes volume fluctuation which stretches the fibers.

    B: Tunica media of the artery is smooth muscle

    C: External elastic lamina is the same as the internal in every way
  • A: Endothelium is just apical to the inner elastic lamina and is simple squamous epithelium

    B: Internal elastic lamina stains black due to the elastic fibers.

    C: Tunica media with smooth muscle

    D: Tunica adventitia is located just outside the external elastic lamina and is LCT

Adipose Tissue

  • A: White adipose cells are histologically named uniclocular adipocytes

    B: Vein

    C: Artery
  • A: Unilocular adipocytes
  • A: Peripherally located nuclei are a distinguishing characteristic of white adipose

    B: Blood Vessels
  • A: Peripherally located nucleus of unilocular adipocyte
