Term: pronephric tubule ciliary transition zone
Name: pronephric tubule
Synonyms: ciliated neck segment
Definition: Bilaterally paired tubes connecting the pronephric glomeruli to the pronephric ducts. In zebrafish and other teleosts, the pronephric nephron and tubules form after the pronephric duct, connecting to the anterior-most tip of the pronephric ducts.

Name: ciliary transition zone
Synonyms: cilial transition zone, cilium transition zone, connecting cilium
Definition: A region of the cilium between the basal body and proximal segment that is characterized by Y-shaped assemblages that connect axonemal microtubules to the ciliary membrane. The ciliary transition zone appears to function as a gate that controls ciliary membrane composition and separates the cytosol from the ciliary plasm.
