non cordata
This is part of the classification for a complex animal like a reptile, fish, amphibian, bird or mammal: Kingdom: Animalia --- animal lifeSubkingdom: Metazoa --- animals with a digestive tractPhylum: Chordata --- animals with a nerve cord So a simple animal without a nerve cord cannot belong to the phylum Chordata, which comprises basically everything from insect and upwards in complexity. Examples:Coral polypSponge
Nerve cord
yes. spinal cord cells are eukaryotic and contain nerve tissues. they are of the animal kingdom.
In reptiles, the nerve cord is part of the central nervous system that runs along the length of the animal's body. It consists of a chain of nerve cells that extends from the brain and helps in transmitting nerve impulses to control various bodily functions like movement and coordination.
No, the notochord and the nerve cord arise from different germ layers. The notochord is replaced by an ossified backbone, though there are still remnants between the vertebrae. The nerve cord, however, is protected by the ossified vertebral column.
Nerve
Yes, pigs, like all mammals, possess a dorsal nerve cord, which is a characteristic feature of chordates. This nerve cord, known as the spinal cord, runs along the back of the animal and is part of the central nervous system, playing a crucial role in transmitting signals between the brain and the rest of the body.
The position of the worms nerve cord compare with your nerve cord is it placement along the ventral surface of the body. Our spinal cord is protected by vertebra were the worms is unprotected.
there is not a ventral nerve cord
because is not an animal whose nerve cord is surroundeda by backbone. Rajabu Obede
An example of an animal that has a notochord, nerve cord, and pharyngeal pouches at some point during its development is a chordate, such as a human. In embryonic development, humans possess these structures, which are characteristics of chordates.
an earthworm's nerve cord is directly opposite that of a human's. the earthworm's nerve cord is along the ventral side (underside) of its body and the human's nerve cord is on the dorsal side (upperside) of the body along all of the internal organs
