In secondary teeth the pulp contains blood vessels and odontoblast.[TAO] dental pulp cell MESH:D003782 GAID:1270 CALOHA:TS-0195 The oral cavity of vertebrates is generally thought to arise as an ectodermal invagination. Consistent with this, oral teeth are proposed to arise exclusively from ectoderm, contributing to tooth enamel epithelium, and from neural crest derived mesenchyme, contributing to dentin and pulp (reference 1); Teeth and tooth-like structures, together named odontodes, are repeated organs thought to share a common evolutionary origin. These structures can be found in gnathostomes at different locations along the body: oral teeth in the jaws, teeth and denticles in the oral-pharyngeal cavity, and dermal denticles on elasmobranch skin (reference 2).[uncertain][VHOG] SCTID:362110007 NCIT:C32451 The part in the center of a tooth made up of living soft tissue and cells called odontoblasts[WP]. loose connective tissue
