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.

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 in the trunk region of the tadpole. The most posterior hypochord persists and begins to ossify, fusing with the coccyx to form the urostyle in the pelvic girdle around NF stage 63.

annotated property: definition
annotated target: 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 in the trunk region of the tadpole. The most posterior hypochord persists and begins to ossify, fusing with the coccyx to form the urostyle in the pelvic girdle around NF stage 63.

The microscopic structure of a gill is such that it presents a very large surface area to the external environment. Gills usually consist of thin filaments of tissue, branches, or slender tufted processes which have a highly folded surface to increase surface area. A high surface area is crucial for effective gas exchange.

Axiom
annotated source: neural plate
annotated property: definition
annotated target: 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.

comment: Properly called a glomus as it extends over multiple body segments.

Axiom
annotated source: glomus
annotated property: definition
annotated target: Multi-tissue structure that is the filtration unit of the pronephric kidney. A glomus is a glomerulus that spans more than one body segment. It is the vascularized filter of the pronephric kidney. Blood is filtered through the glomus and the filtrate deposited into the coelom early in development, or the nephrocoel later in development. The glomus contains podocytes with well developed foot processes that are anatomically indistinguishable from the podocytes of adult glomeruli. The two glomera are linked via a narrow bridge called the glomeral nexus.

subclass of: anatomical system
subclass of: Restriction
  on property: ends during

definition: Part of the circulatory system that consists of a series of vessels that collect blood (exclusive of erythrocytes) which seeps through capillary walls and return it to the veins. The lymphatic system of vasculature drains lymph fluid from the tissue spaces of most organs and returns it to the blood vasculature for recirculation. The lymphatic sytem functions in immune responses. Anurans generate a lot of lymphatic fluid, largely as a consequence of their very leaky vasculature and high interstitial compliance. Lymph is ultimately pumped into the venous system by paired, dorsally located lymph hearts. Hedrick et al (2007) showed that lung inflation and deflation assists lymph movement. Lymph is moved during lung deflation to the subvertebral sac from anterior and posterior lymph sacs. During lung inflation, increased lymph sac pressure moves lymph to axillary regions, where lymph hearts can return lymph to the vascular space.
