Notochord secretes
WebHumans are not chordates because humans do not have a tail. Vertebrates do not have a notochord at any point in their development; instead, they have a vertebral column. The endostyle secretes steroid hormones. Show … WebThe notochord supports the whole tail of the larva but just part of its body. This arrangement gives the subphylum its name, Urochordata (Greek root words uro meaning tail and chord meaning string ). The tunicate larva is a bilaterally symmetrical, free-swimming animal that looks like a tadpole or a lancelet (Fig. 3.100).
