Muscle, kidneys, and dermis are all derived from the mesoderm primary germ layer. Skin (ectoderm), tooth dentin (ectoderm and mesoderm), and tonsils (endoderm) are derived from different primary germ layers. Bones (mesoderm), blood (mesoderm), and thyroid gland (endoderm) are also derived from different primary germ layers. Uterus (mesoderm and endoderm), bladder (endoderm), and pituitary gland (ectoderm) are also derived from different primary germ layers.
