Surface structure that has an important role in tadpole locomotion. It starts to develop along the trunk and tail of the embryo at the tail bud stage and continues to grow until the start of metamorphosis when it begins to regress. It consists of flattened epidermal cells elevated into a keel-like structure by a supporting core of mesenchyme and extracellular matrix.

brain
xenopus_anatomy
Organ that is a component of the central nervous system and is responsible for the coordination and control of bodily activities and the interpretation of information from the senses. It appears when the neural tube segregates in forebrain, midbrain, and hindbrain at NF stage 22. The general pattern of the brain has been mainly established at NF stage 28. Yolky material is consumed and the fibre tracts and later the commissures develop. In general all of its parts are well developed at NF stage 53 and later development consists mainly of growth and some further cytological differentiation. In the period of metamorphosis only topographical changes take place.

Transient structure that lies immediately ventral to the notochord in the embryo, likely required for the formation of the dorsal aorta. A slight depression marks the future hypochord at NF stage 20 and its segregation from the dorsal endoderm begins at NF stage 24. It progresses from anterior to posterior and is complete by NF stage 28. At NF stage 32 it is present as a dorso-laterally flattened ribbon of yolk-laden cells. It degenerates by apoptosis and by NF stage 43 is no longer detectable as a distinct structure.

At NF stage 40 the right and left primordia have fused just above the gasto-duodenal vein. At NF stage 42 blood vessels penetrate into the crevices between the pancreatic acini making them more conspicuous.

A region of embryonic ectodermal cells that lie directly above the notochord. During neurulation, they change shape and produce an infolding of the neural plate (the neural fold) that then seals to form the neural tube. At NF stage 11.5 is the first indication of neural plate within the sensorial layer of ectoderm. It extends to near the animal pole by NF stage 12.5 and the entire plate is faintly delimited by NF stage 13.

Type of neuron that is a primary mechanosensory cell, with peripheral neurites innervating the skin with free nerve endings. It first appears in trunk levels at NF stage 33/34, and at NF stage 35/36 has somas that are the largest in the spinal cord. It forms a nearly continuous double row of cells along the cord's medial dorsal surface and contributes ascending and descending axons to the dorsal tract. It appears well back in the tail by NF stage 39, begins to decline at NF stage 50 and is few in number, with pycnotic nuclei, at NF stage 55.
