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.
How does the earthworm's main nerve cord differ from humans?
The earthworm's main nerve cord is located on its belly and runs along the length of its body, whereas humans have a central nervous system composed of the brain and spinal cord. The earthworm's nerve cord is simpler and coordinates basic reflex responses, while the human central nervous system is more complex and involved in higher brain functions.
What does the dorsal nerve chord develop into in vertebrates?
In vertebrates, the dorsal nerve cord develops into the central nervous system, which consists of the brain and spinal cord. The neural tube forms from the dorsal nerve cord during embryonic development, giving rise to these critical components of the nervous system. This structure is essential for processing sensory information and coordinating responses throughout the body.
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
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 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.
Starting from the spinal cord trace a motor pathway to the adductor muscle of the thigh Include the spinal cord root spinal nerve nerve plexus and specific peripheral nerve involved in the pathway?
starting in the spinal cord, trace a motor pathway to the adductor muscles of the thigh. Include the spinal cord root, spinal nerve, nerve plexus, and specific peripheral nerve involved in the pathway
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).
What animals have a tubular nerve cord and gill slits at some point in their lives?
No, not all vertebrates have tubular nerve cord.
A vertebrates backbone is part of what internal skeleton?
Ventral nerve cord, vertebra, dorsal nerve cord, and notocord.
