mesenchyme

(mĕz′ən-kīm′, mĕs′-)
n.
The part of the embryonic mesoderm, consisting of loosely packed, unspecialized cells set in a gelatinous ground substance, from which connective tissue, bone, cartilage, and the circulatory and lymphatic systems develop.

Etymology: Gk, mesos + enchyma, infusion
a diffuse network of tissue derived from the embryonic mesoderm. It consists of stellate cells embedded in gelatinous ground substance with reticular fibers. mesenchymal, adj.

mesenchyme

a loose, cellular animal tissue that arises from the embryonic mesoderm, and functions as packing around internal organs. Mesenchyme can be thought of as the animal equivalent of PARENCHYMA in plants.

mesenchyme (mes´engkīm),

n 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.

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.
