The cells which make up nerve tissue are called nephrons.Is this true?

hey the are not nephrons they are neurons . neurons are a part of the kidney

This is probably a motor neuron you are describing.  There are the branches to make the synapses because the motor neuron must innervate a muscle.  They must synapse at multiple places over the muscle cell to create the proper action potential for contraction.  Interneurons do not always have to be myelinated either.  Interneurons are those which only communicate from neuron to neuron, and these are mostly found in the brain and spinal cord.  The unmyelinated neurons make up the gray matter common to these areas.

The retina is a thin layer of neural cells that lines the back of the eyeball of vertebrates and some cephalopods. In vertebrate embryonic development, the retina and the optic nerve originate as outgrowths of the developing brain. Hence, the retina is part of the central nervous system (CNS). It is the only part of the CNS that can be imaged directly.

I'm not quite sure what you are asking, but I think the answer you want is that each ganglion contains the cell bodies of the sensory neurones.\nUnipolar motor neurones have their cell bodies within the spinal cord.

I assume you are talking about the nerve itself, i.e. the bundle of axons and dendrites, not the cell bodies.  Axons and dendrites in the nerve are not cells, but extensions of cells, and thus can't form the basis of cancer (this requires a nucleus and DNA).  The axons and dendrites are covered, supplied, and myelinated by Schwann cells, which are far and away the predominant cell in the nerve (again, discounting the neurons in which the axons and dendrites originate).  There are also connective tissue cells, like fibroblasts, and vascular cells as well, each of which may form tumors.  However, schwannomas are distinctive peripheral nerve cells, and form the great majority of tumors here.

Neurons have the same organelles as other cells.  They have nuclei, mitochondria, ER, etc.  But, neurons may have higher numbers/concentrations of certain organelles because neurons use a lot of energy in maintaining ion concentrations and they secrete a lot of stuff (neurotransmitters).  I'm not sure how specific you need information, but "Principles of Neural Science" by Kandel is a great resource for all things neuroscience.  \n\nAs for the G0 phase stuff, although most neurons appear not to be able to undergo mitosis, this is not entirely true.  Recent research indicate that neurons in the olfactory bulb and hippocampus seem to undergo mitosis.  Why most neurons are in G0 isn't completely understood, but it may be something within the environment rather than the cell itself.

Nerves stop undergoing mitosis when they reach maturity. Before maturity, they are stem cells, which are basically undecided cells. Stem cells pertain to parkinsons and alzhimers because they can be grown into whatever cells the patient needs. The new cells replace the damaged ones. \n\nCheck out my podcast, the Daily Latte.\niTunes: http://phobos.apple.com/WebObjects/MZStore.woa/wa/viewPodcast?id=120927843&s=143441\nWebsite: http://www.wolftime.com

Nervous system is devided in to two parts: central(CNS) and peripheral nervous systems(PNS).CNS is the brain and the spinal cord,PNS is composed of many nerves that contains neurones (nerve fibers),these neurones are of two types,Efferent(sensory) neurones carry the messages from the different body organs to the CNS,while the afferent(motor) neurones carry the messages from the CNS back to the different organs. When any part of the system is stimulated by any stimulant;whether it is external or internal,this stimulation will be carried as a message to the CNS where it is translated and then appropriate action is planned, this action then is carried by the motor neurones back to target cells or organs to carry on the plan of action tward that stimulant...It's  a complicated process that really shows the power of the creator who designed it---our lord

"Myelin is an electrically insulating phospholipid layer that surrounds the axons of many neurons. It is an outgrowth of glial cells: Schwann cells supply the myelin for peripheral neurons while oligodendrocytes supply it to those of the central nervous system. Myelin is considered a defining characteristic of the (gnathostome) vertebrates, but it has also arisen by parallel evolution in some invertebrates."

They have recently discovered that nerve tissue actually can divide and regenerate, but at a veeeery slow rate. The reason can be explained in terms of the cell cycle. Nerve cells are in a phase known as G0 this is known as a resting phase. Nerve cells were thought of as permanent tissues. The other types of tissues that you get are stable and labile. Muscle is another tissue that is permanent. Liver tissue is very interesting. it is usually permanet but when massive damage to the liver occurs, the cells can get out of g0 and undergo mitosis to repair the tissue!Hair cells and skin are types that are rapidly dividing and can regenrate the easiest!

I work in the field of nerve regeneration, though not optic nerve.  The optic nerve is a bundle of literally millions of microscopic fibers-all in a space a few millimeters in circumference.  The nerve cells that produce these fibers are found in the brain itself.  Retinal cells in the eye signal to these fibers, which then carry the signal to the cells of the brain.  In order to transplant an eyeball, you would have to connect those millions of nerve fibers to the retinal cells, in exactly the right order.  There are other complications, but that is the most difficult-we simply dont know how to make those millions of microscopic connections.

D) Loop of Henle\n\nIt is the only part of the nephron of those listed in the choices that is actually in the renal medulla

neural science is the study of brain cells called neurons.\n\nand your spelling is fine.
