What is an animal that has a notochord nerve cord and slits in the throat area?
Vertebrates are in the phylum Chordata. Members of this phylum are called chordates. Chordates share some common traits. At some point in their life cycle, they have a notochord, a nerve cord, and pharyngeal (fayr uhn JEE uhl) slits in the neck or throat.
What are animals that have a dorsal nerve cord notochord and pharyngeal gill slits and show development?
Chordates are animals that have a notochord, post-anal tail, dorsal hollow nerve cord, and pharyngeal slits. Chordates include all vertebrates and some invertebrates.
Which phylum of animals has a nerve cord?
The phylum chordata is named for the notochord, a longitudinal, flexible rod between the digestive tube and the nerve cord; in vertebrates, this is the spinal column. The chordates are also characterized by a dorsal nerve cord, which splits into the brain and spinal cord.
Do amphibians have a nerve cord?
Amphibians developed with the characteristics of pharyngeal slits/gills, a dorsal nerve cord, a notochord, and a post-anal tail at different stages of their life.
What is tubular nerve cord?
Medical Definition of nerve cord
: the dorsal tubular cord of nervous tissue above the notochord of a chordate that in vertebrates includes or develops an anterior enlargement comprising the brain and a more posterior part comprising the spinal cord with the two together making up the central nervous system.
Which animal has gills as larvae?
Many aquatic salamanders and all tadpoles have gills in their larval stage, with some (such as the axolotl) retaining gills as aquatic adults.
What are pharyngeal gill slits?
Pharyngeal gill slits are a chordate feature; these are openings between the pharynx to the outside. They have been modified hin the time of evolution. In primitive chordates, these slits are used to filter food particles from the water. In fishes and some amphibians, the slits bear gills and are used for gas exchange.
Do humans have pharyngeal slits?
Pharyngeal slits are openings in the pharynx that develop into gill arches in bony fish and into the jaw and inner ear in terrestrial animals. The post-anal tail is a skeletal extension of the posterior end of the body, being absent in humans and apes, although present during embryonic development.
Where is nerve cord of chordate animals located?
In chordate animals, a long, hollow tubular tract of neural tissue located above the notochord that develops into the spinal cord and the brain.
What do animals in the phylum Chordata have in common?
Animals in the phylum Chordata share four key features: a notochord, a dorsal hollow nerve cord, pharyngeal slits, and a post-anal tail.
What organisms are in phylum Chordata?
Most species within the phylum Chordata are vertebrates, or animals with backbones (subphylum Vertebrata). Examples of vertebrate chordates include fishes, amphibians, reptiles, birds, and mammals. A modern human—one species of mammal—is a familiar example of a chordate.
Do chordates have gills?
Chordates also have pharyngeal slits. These are openings that connect the pharynx or throat to the outside of the neck. In some primitive species, the slits are used to filter food out of the water. In other species, like fish, the pharyngeal slits have gills.
Do invertebrates have a nerve cord?
Most invertebrates have a pair of solid nerve cords, situated ventrally and bearing segmentally arranged ganglia. All animals of the phylum Chordata have a dorsal hollow nerve cord; in vertebrates this is the spinal cord.
Do frogs have a dorsal nerve cord?
Next, frogs are chordates. The characteristic of chordates are notochord, a dorsal nerve cord, pharyngeal slits, an endostyle, and a post-anal tail, for some part of their life.
