urochorda

Example:During embryonic development, the notochord (urochorda) is crucial for the formation of the vertebral column.

Definition:The flexible, rod-like structure found along the anterior-posterior axis in the early embryonic development of chordates including vertebrates, serving as a support structure and a center for the development of the vertebral column

Example:The notochord (urochorda) is a defining feature of all chordates.

Definition:A phylum of animals comprising vertebrates, which include fish, amphibians, reptiles, birds, and mammals, as well as two invertebrate subphyla, hyperophotomorpha and cephalochorda.

Example:Vertebrates, like humans, have a lengthened and modified notochord (urochorda) known as the vertebral column.

Definition:An animal that possesses a vertebral column, a specialization of the notochord that provides a structure for the attachment of muscles and protection of the spinal cord or nerve cord.

Example:The spine contains the notochord (urochorda) in its early developmental stages.

Definition:The series of small bones that run the length of the back and is part of the vertebral column in vertebrates, providing support and protection for the spinal cord.
