The outer, or parietal, one of the two lamellae into which the vertebrate blastoderm divides on either side of the notochord, and from which the walls of the body and the amnion are developed. See Splanchnopleure.
a.
Having the tail fin divided into two equal parts by the notochord, or end of the vertebral column; protocercal. See Protocercal.
n.
The anterior end of the notochord and its bony sheath in the base of cartilaginous crania.
n.
One of the primitive masses, or segments, into which the mesoblast of the vertebrate embryo breaks up on either side of the anterior part of the notochord; a mesoblastic, or protovertebral, somite. See Illust. of Ectoderm.
a.
Situated on either side of the notochord; -- applied especially to the cartilaginous rudiments of the skull on each side of the anterior part of the notochord.
n. pl.
One of the grand divisions of the animal kingdom, comprising all animals that have a backbone composed of bony or cartilaginous vertebrae, together with Amphioxus in which the backbone is represented by a simple undivided notochord. The Vertebrata always have a dorsal, or neural, cavity above the notochord or backbone, and a ventral, or visceral, cavity below it. The subdivisions or classes of Vertebrata are Mammalia, Aves, Reptilia, Amphibia, Pisces, Marsipobranchia, and Leptocardia.

n.
An elastic cartilagelike rod which is developed beneath the medullary groove in the vertebrate embryo, and constitutes the primitive axial skeleton around which the centra of the vertebrae and the posterior part of the base of the skull are developed; the chorda dorsalis. See Illust. of Ectoderm.
n. pl.
The lowest class of Vertebrata, including only the Amphioxus. The heart is represented only by a simple pulsating vessel. The blood is colorless; the brain, renal organs, and limbs are wanting, and the backbone is represented only by a simple, unsegmented notochord. See Amphioxus.
n.
The inner, or visceral, one of the two lamellae into which the vertebrate blastoderm divides on either side of the notochord, and from which the walls of the enteric canal and the umbilical vesicle are developed. See Somatopleure.
a.
Around the notochord; as, a perichordal column. See Epichordal.
a.
Situated on the ventral side of the notochord; as, the subnotochordal rod.
