The 'dorsal-fin' extends upward from the back of organisms; so anything Ventral must reside near to an organism's front-side.
there is not a ventral nerve cord
no
no
the ventral root carries motor response
A ventral nerve cord can be found in on the bottom (or lay on the bottom) of the organisms, such as grasshoppers and earthworms. Hope this helps! - AJ
Planarian ventral nerve cords are bundles of nerve fibers located on the ventral (underside) surface of the planarian flatworm. These nerve cords coordinate the worm's movement, feeding, and response to stimuli. They are part of the planarian's simple nervous system that allows it to navigate its environment.
spinal nerve
Would lead to loss of both sensory & motor function. Ventral ramus is the anterior division of a spinal nerve.
The ventral ramus of a spinal nerve contains both sensory and motor nerve fibers. These fibers innervate the muscles, joints, and skin on the front part of the body.
yes!
ventral root
Yes, the ventral root of a spinal nerve is the efferent motor root, consists of axons of motor neurons. It joins the dorsal root to form a mixed spinal nerve, which consists of afferent sensory neurons (from the dorsal root) and efferent motor neurons (from the ventral root). Therefore severing the ventral root will result in a loss of motor function for the myotome supplied by that spinal nerve.
