Generally speaking, the ectoderm differentiates to form epithelial and neural tissues (spinal cord, peripheral nerves and brain). This includes the skin, linings of the mouth, anus, nostrils, sweat glands, hair and nails, and tooth enamel. Other types of epithelium are derived from the endoderm.

Which organs are mesodermal in origin?

The mesoderm gives rise to the skeletal muscles, smooth muscle, blood vessels, bone, cartilage, joints, connective tissue, endocrine glands, kidney cortex, heart muscle, urogenital organ, uterus, fallopian tube, testicles and blood cells from the spinal cord and lymphatic tissue (see Fig.

Are lungs ectodermal in origin?

Formation of the lung buds

The epithelium of the internal lining of the larynx, trachea, bronchi and lungs is entirely of endodermal origin. The cartilagenous, muscular and connective tissue of trachea and lungs are derived from splanchnic mesoderm. The lung bud is in open communication with the foregut.
