Nerve Cells

Directions: Label the neuromuscular (myoneural) junction. Then, read the case study below and answer the questions. Each question should be answered with FIVE or more sentences.

The nervous system is made up of basic units called neurons. The main role of the neurons is to receive, integrate and transmit information throughout the body. There are some neuroglial cells found in nervous system aswell which provide support to the neurons by giving protection and nourishment Neurons have nerve processes that looks like finger like projections extended from the nerve cell body. They also contain axons and dendrites which enable them to transmit signals throughout the body. Normally, axon carry signals away from the cell body and dendrites carry signals toward the cell body according to Regina Bailey (2013). Neurons have three different shapes: bipolar, unipolar and multipolar where bipolar has two neuronal processes coming out of the cell body, unipolar has only one neuronal process coming out of the cell body and multipolar has many neuronal processes coming out of the cell body.

Neurons, nerve cells, have three basic parts: the cell body, dendrites, and axon. Neurons transmit signals to other nerve cells and throughout the body. They are simple components in the nervous system. The cell body includes the nucleus, which is the control center of the neuron. The dendrite branches off the cell body and receives information. The axon is attached to the cell body and sends information away from the cell body to other cells. When the axon goes through myelination, the axon part of the neuron becomes covered and insulated with fat cells, myelin sheath. This increases the speed and efficiency of information processing in the nervous system. Synapse are gaps between neurons, this is where connections between the axons and dendrites.

Neurons are information- processing units in the central nervous system that receive and transmit information. It is made up of an axon, dendrites and a cell body. The nucleus and cytoplasm are contained in the cell body. The axon starts from the cell body, dividing into smaller branches and then ends at the nerve terminals. The dendrites also branch from the cell body, receiving information from the other neurons. Axons from other neurons forms

1. Neurons is a basic building block of the nervous system. The sensory nerves carry the message from body tissues to the brain and spinal chord to be processed. The motor neurons are then used to send instructions to the body tissue from the brain and spinal cord. Dendrites, which are connected to the body cell (soma) receive information and pass it through the axon. Myelin sheath covers the axon and helps speed the process. When triggered by a signals from our senses or other neurons, the neuron fires an impulse called the action potential. The resting potential is the neuron’s visual charge of positive

|  A neuron is known as an excitable cell that can process and transmit information through electrical and chemical signals. Neurons are the core components of the nervous system, which includes the brain, spinal cord and nervous system.

Neurons are nerve cells that transmit nerve signals to and from the brain at up to 200 mph. The neuron consists of a cell body (or soma) with branching dendrites(signal receivers) and a projection called

Our skilled staff at Southeast Veterinary Neurology use this test to record the electrical activity of muscles and can be helpful in enabling us to diagnose problems in your pet's motor function. The motor function consist of several parts. They can be tested by stimulating a peripheral nerve and then measuring the velocity at which this stimulus travels through the motor and sensory nerves and then comparing the results with normal baselines. This enables us to narrow down a diagnosis in the event your pet is experiencing problems in motor function.

• Nerve conduction studies. These record muscle activity and check how well your muscle nerves send signals.

Neurons (also known as neurons, nerve cells and nerve fibers) are electrically excitable and the most important cells in the nervous system that functions to process and transmit information. Neurons have a large number of extensions called dendrites. They often look likes branches or spikes extending out from the cell body. It is primarily the surfaces of the dendrites that receive chemical messages from other neurons.

Human brain consists of billions of cells interconnected together, with each performing its separate functions. It consists of two explicit categories of nerves: neurons and glia cells. Neuron is a single nerve cell in the entire nervous system; which is electrically excitable cell that carries information after being processed via chemical or electrical signals. One of its key characteristics is that it does not undergo cell division. In addition, it maintains a voltage gradient for all the neurons across its membranes. Glia cells, on the other hand, its functionality is to maintain homeostasis.

The two components of the central nervous system (CNS) are the brain and the spinal cord. Communication between the brain and the spinal cord happens through motor neurons, which are nerve cells that enable motor movement. Each motor neuron is made up of a cell body, which holds all the cell components, dendrites which send information it receives to the cell body, and an axon which sends nerve impulses to the muscle (Porth & Matfin, 2009). As electrical impulses are sent through the motor neuron, it stimulates the muscle fibers in the body to move. This is the process in which motor function happens. Therefore, the basic abilities to breathe, speak, swallow, walk and button a shirt are
