processes of the cervical vertebra, along the vertebral 

 column, where it is reinforced by white fibrous tissue, 

 also in the ligamentum subflava, in the vertebral 

 column, in bloodvessels, and in the skin. 



3. Mucous or Embryonic Tissue. This is found in

 the former in bundles, the latter generally single. 

 Among these fibers are a few scattered, mostly spindle-

Areolar tissue, composed of bundles of white fibrous tissue and branched 

 strands of yellow fibrous tissue loosely intertwined. (Gerrish.) 



4. Retiform or Reticulum Tissue. This forms the 

 frame-work of glands and gland-like organs. The 

 fibrils are arranged in delicate bundles, in the meshes
