The ventral nerve cord runs throughout an earthworm's body. When they start to branch from ganglion the nerve cords are still present throughout the segments.
Nerves is a plural noun. Nervous is an adjective.
c5 and c6 are vertebrae in the neck arthritis can cause a growth of bone that ends up putting pressure on the nerves passing out of the spinal chord into the body, in this case I think your arms.
The main part is the nerves the nerves tell your body to move.
There is a big difference, both structural and functional between the veins and the nerves.Structural differences:1. The nerves are composed of nerve cells called NEURONS. A neuron is composed of the body which has NUCLEUS inside, long extension branch called AXON (which is surrounded by MYELIN in some nerves), short extension branches called DENDRITES and SYNAPTIC TERMINAL.2. A vein is a tubular organ composed of 3 layers:a) tunica externa (epithelial cells)b) tunica media (smooth muscle cells)c) tunica interna (endothelial cells)Functional differences1. The nerves function is to carry information from the receptor (f.e. skin) to the brain and from the brain to the effector (f.e. striated muscle). This is called reflexive arch.2. The definition about a vein is: a blood vessel that transports blood to the heart.Both arteries and veins are types of nerves
Yes, but not somatic nerves. Instead the heart is enervated by the autonomic nervous system (used mainly to speed up and/or slow down the heart rate). There is also an internal set of nerves (referred to as Perkingi fibers) that are used to synchronize the beats of the heart.
An earthworm has a paired brain attach to it nerve cord, that flows to its ganglia. The Clitellum ( the ring or band on the worm) is were the worm senses things. An earthworm can also not feel pain.
Dorsal and ventral roots are a feature of spinal nerves only. Cranial nerves do not have dorsal and ventral roots.
The axons of ganglion cells in the retina form the optic nerves.
Nerves from a ganglion typically project to target tissues, organs, or other ganglia. They carry information such as sensory input or motor commands. The specific pathway and function of the nerves depend on the location and type of ganglion.
The ventral nerve cord makes up nearly all of the nervous system in the earthworm. It goes from the anterior (front) end to the posterior (back) end. It's function is simple; it's the nerves in the worm! If dissected, the nerve cord looks like a thin white line on the ventral (belly) side on the inside of the skin.
Ventral nerves are nerves that emerge from the spinal cord on the ventral side (front) of the body. They carry motor commands from the brain to muscles and organs, controlling movement and functions such as respiration and digestion.
After nerves leave the gaglion they go to the, Intestine
After nerves leave the gaglion they go to the, Intestine
They go to the intestine.
Peripheral nerves.
Nerves branch out from the spinal cord.
The pedal ganglion supply nerves to the foot muscles of mollusks.
