large and myelinated nerve fiber that originate in the anterior horns of the spinal cord after entering the muscle branches in axonal terminals that end about near the midpoint of muscle by forming a neuromuscular junction. at that point, nerve terminal ends into a small invaginated part of the muscle membrane called synaptic gutter.

You are talking about neuromuscular junction, the terminus where the neurotransmitter is dumped.

A large nerve fiber covered with myelin sheath that came from the front (anterior horns) portions of the spinal cord (large main nerve connected from the medulla oblongata of the brain traversing the cervical until the sacral portion of the vertebral column) after entering the muscle branches in axonal terminals that end about near the midpoint of muscle by forming a neuromuscular junction (simply said, the axon of the nerve is fused with a muscle fiber creating a neuromuscular junction) At that point, nerve terminal (nerve endings) ends into a small invaginated part of the muscle membrane called synaptic gutter. (nerve ends in a small pocket in the covering of the muscle called a synaptic gutter)

This sentence is full of many very technical terms. To begin to understand the sentence, I'd have to know the meaning of the terms. Here's a good online medical dictionary from the National Library of Medicine. http://www.nlm.nih.gov/medlineplus/mplusdictionary.html

"Start there to look up the meanings of the terms you don't understand. Then repeat the sentence substituting an alternative phrase that means the same as the difficult word. See if that brings the sentence into focus.

For example, I have no idea what myelinated nerve fiber is, so I looked it up and had to move backwards through several definitions to get to the root term. I found out it refers to: a soft white somewhat fatty material that forms a thick myelin sheath about the protoplasmic core of a myelinated nerve fiber

So this is a large nerve fiber with a white somewhat fatty material forming a sheath around it that originates on the anterior horns of the spinal cord.

Ok. I know anterior means back, and horns in this case are spur like things on the spinal column. So I'm starting to get a picture of this nerve fiber.

What else does it tell me? It enters the muscle branches in axonal terminals. What are those? Back to the dictionary.
"a usually long and single nerve-cell process that usually conducts impulses away from the cell body "

Ok. After it reaches those spurs on the spinal column it enters the muscles through long single nerve-cell proceeses.

What's next?

See how it's done? By the time you have strung together all the definitions of the medical jargon, you can figure out how this nerve reaches the spine and transmits information to a muscle.

I'm a librarian, not a biologist, but I would have a solid understanding of this thought by the time I worked my way through the entire sentence.

If you read this sort of material a lot, I'd suggest bookmarking the Medline Plus website twice -- once for the basic webside and once for the dictionary. Medline Plus offers free, authoratative medical information from many US government departments.

large insulated nerve fiber that originates on the spinal cord closer to the stomach then the backbone after entering the muscle it branchs out with receptor nerve endings able to recieve information from the muscle in the middle of the muscle in a small channel that the muscle uses to send different neurotransmitters to inform the brain whats going on.

its describing a nerve that controls a muscle.

A lot of medicine is vocabulary. You need a rich language to be able to specify specific parts of the body, whats going on there and why.

You should look up each word you dont know in an online dictionary. Its a healthy exercise.

It kinda sounds like the definition of how the spinal cord enters or connects to the brain... although, you probably took that from a book... hence you should have the answer in from of you.
