What is the difference between veins and nerves?
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
Do you have nerves in your heart?
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.
What are the parts of earthworms nervous system?
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.
What is the function of the ventral nerve cord in an earthworm?
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.
Is true Both spinal and cranial nerves have dorsal and ventral roots?
Dorsal and ventral roots are a feature of spinal nerves only. Cranial nerves do not have dorsal and ventral roots.
Many nerves leaves from ganglion where these nerves go?
After nerves leave the gaglion they go to the, Intestine
Where do nerves go when they leave the ganglion in the crayfish?
After nerves leave the gaglion they go to the, Intestine
Where do the nerves leave from each ganglion in a crayfish?
They go to the intestine.
The axons of which of these neuron layers form the optic nerves?
Ganglion Cells
Small groups of nerves outside the brain and spinal cord?
Peripheral nerves.
From where do the nerves branch out?
Nerves branch out from the spinal cord.
What is the function of the pedals?
The pedal ganglion supply nerves to the foot muscles of mollusks.
What region of the body is served by the ventral rami of spinal nerves?
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.
What is the superior mesenteric ganglion?
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.
