Examples from the Web for endostyle
According to Kowalevsky the heart is formed during larval life as an elongated closed sack on the right side of the endostyle.
On the ventral wall of the branchial sack there is formed a narrow fold with thickened walls, which forms the endostyle.
Between the nervous system and the endostyle an involution appears, which gives rise to the mouth.
The thyroid is, in fact, in this stage in a condition corresponding exactly with the endostyle of Amphioxus.
