What is a nerve cord for a reptile?
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.
What organisms have pharyngeal gill slits and a dorsal hollow nerve cord at some time in their development?
Organisms that have pharyngeal gill slits and a dorsal hollow nerve cord at some point in their development include chordates, such as fish, amphibians, reptiles, birds, and mammals. These features are key characteristics of chordates during their embryonic stages.
Do frogs have a dorsal nerve cord?
Features are a hollow nerve cord in the dorsalside of the body; ... Larger sharks have been said to exist, but at the moment have not been documented
Is the nerve cord a flexible rod that supports a chordate's back?
Yes, the nerve cord is part of the chordate anatomy, but it is not a flexible rod that supports the back; rather, it is the notochord that serves as a flexible rod providing support. The notochord is a key characteristic of chordates during their development, offering structural support and serving as a precursor to the vertebral column in vertebrates. The nerve cord, which develops into the spinal cord, runs alongside the notochord and is responsible for transmitting nerve signals.
What is the function of a nerve cord in a worm?
While humans and other vertebrates have a spinal column that runs down their back, or dorsal side, earthworms possess a nerve cord consisting of two strands that runs down their belly, or ventral side. The nerve cord of an earthworm relays impulses from receptors in the worm's anterior to posterior parts of its body.
What is the positioning of a birds main nerve cord?
Dorsal.
Does birds have spinal cord?
Yes, they have a dorsal (at the back) nerve chord as they are vertebrates ( they have an internal skeleton).
How does the position of the worms nerve cord compare with your nerve cord?
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.
What does the ventral nerve cord do in a earthworm?
there is not a ventral nerve cord
How does the position of a worms nerve cord compare with your nerve cord?
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
Does a kangaroo have a dorsal nerve cord notochord?
Yes
Are chordates a central solid nerve cord?
Yes, chordate's nerve cord is hollow as opposed to animals that are non chordate with a nerve cord which are solid.
What type of nerve cord do all chordates possess?
A dorsal, hollow nerve cord.
What is an animal with a nerve cord called?
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

Does the stingray have a nerve cord?
yes it does
Does a kangaroo have a dorsal nerve cord?
Yes. Kangaroos, like humans, are vertebrates, which are a subset of chordates (having a dorsal nerve cord).
