What does the intermediate mesoderm, lateral plates, and paraxial mesoderm give rise to later in development?
|
The intermediate mesoderm gives rise to the urogenital system, and the lateral plate mesoderm is involved in body folding.The two columns of paraxial mesoderm, one on either side of the notochord and the developing neural tube, differentiate and segment into blocks of tissue called somites.

What tissues does the ectoderm give rise to?
|
Ectoderm: central nervous system, epidermis (skin) and its appendages (hair and nails), mammary glands, pituitary gland, subcutaneous glands, and enamel of teeth.

|
What tissues does the mesoderm give rise to?

What do neural crest cells give rise to?
|
Neural crest cells (which were derived from neuroectoderm): spinal (dorsal root), cranial (CNs V, VII, IX, X) and autonomic ganglia; ensheathing (Schwann) cells of the peripheral nervous system; pigment cells of the epidermis, the adrenal medulla, the arachnoid and pia maters, and more.
