This is part of the classification for a complex animal like a reptile, fish, amphibian, bird or mammal: Kingdom: Animalia --- animal life
Subkingdom: Metazoa --- animals with a digestive tract
Phylum: 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 polyp
Sponge
The longitudinal bundles of nerve fibers within the spinal cord that comprise major nerve pathways are called tracts. These tracts are organized based on their function and transmit information to and from different regions of the body to the brain.
The optic nerve is the cord at the back of the eyeball, it also carries impulses from the eye to the brain.
Spinal Cord
The testicular nerve and the nerve to the cremaster innervate the vas deferens in the spermatic cord.
sharks, goldfish, cockroach spider rat mospuito and hampster. a dorsal nerve cord is your spinal cord
non cordata
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.
Yes, dolphins have a dorsal nerve cord. The dorsal nerve cord is an embryonic feature unique to chordates. Is it hollow and most mammals have one.
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.
ganglia
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.
Afferent nerve fibers enter the spinal cord through the dorsal roots.
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.
there is not a ventral nerve cord
because is not an animal whose nerve cord is surroundeda by backbone. Rajabu Obede
