An embryonic connective tissue that migrates from the primitive epidermal and hypodermal layers and later produces the mesodermal layer. It is in this layer that embryonic tooth buds begin to form.
| Veterinary Dictionary: mesenchyme |
The meshwork of embryonic connective tissue in the mesoderm, from which are formed the muscular and connective tissues of the body and also the blood vessels and lymph vessels.

Mesenchyme, or mesenchymal connective tissue, is an example of reticular connective tissue, a type of loose connective tissue, which is derived from all three germ layers and located within the embryo .[1] Mesenchyme is characterized morphologically by a prominent ground substance matrix containing a loose aggregate of reticular fibrils and unspecialized cells.[2] The cells are capable of developing into connective tissue, bone, cartilage, the lymphatic system, and the circulatory system.[3][4]

Ectomesenchyme has similar properties to mesenchyme. The major difference is that ectomesenchyme is usually considered to arise from neural crest cells,[5] which are a critical group of cells that form in the cranial region during early vertebrate development. Thus, ectomesenchyme plays a critical role in the formation of the hard and soft tissues of the head and neck such as bones, muscles and most importantly the branchial arches.
