The structure that consists of ectodermal contributions is; all neural tissue, including the brain and spinal cord
<h3>What are the structures of ectodermal contributions?</h3>
Ectodermal organs include hair, teeth, and many exocrine glands. They originate from two adjacent tissue layers: the epithelium and the mesenchyme.
Similar sequential and reciprocal interactions between the epithelium and mesenchyme regulate the early steps of development in all ectodermal organs.
The main function of the ectoderm is to form the central nervous system (brain and spinal cord). Following gastrulation, the mesoderm forms the rod-like notochord which signals the adjacent dorsal ectoderm to thicken and form the neural plate.
Thus, the structure that consists of ectodermal contributions is all neural tissue, including the brain and spinal cord
