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.
It is a mass of nerve tissue existing outside the central nervous systems
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.
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.
Dorsal and ventral roots are a feature of spinal nerves only. Cranial nerves do not have dorsal and ventral roots.
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.
Ganglion Cells
Peripheral nerves.
Nerves branch out from the spinal cord.
The pedal ganglion supply nerves to the foot muscles of mollusks.
The ventral rami serves as a form of intercostal nerves, which supply the muscles between the ribs and the skin and muscles of the anterior and lateral trunk.
The Ganglion is a fusion of nerves when defined in common terms. Superior means Above, Mesentric- Intestine(large), Ganglion (brain in the earth worm) In the upper part of the superior mesenteric plexus close to the origin of the superior mesenteric artery is a ganglion, the superior mesenteric ganglion. The superior mesenteric ganglion is the synapsing point for one of the pre- and post-synaptic nerves of the sympathetic division of the autonomous nervous system. This nerve goes on to innervate part of the large intestine.
