atrophy [SMA] is a disorder in which‚ you have a loss of motor neurons. Your muscle symmetry is often off. In addition‚ there is muscle weakness in your spinal cord. This occurs in a hard time sitting up and holding your head up on your own. It is just like when you are a newborn and you need a pillow to sit on the couch. A few major causes of SMA are loss of motor neuron cells or nerve cell. This mutation leads to a deficiency of motor neuron cells or nerve cells. The disorder SMA is tied to the gene

different parts. The video describes the three important jobs our neurons do: receive information from other cells‚ process information‚ and transmit it to the rest of the body. Without our neurons we would have no brain activity. All behavior begins with an action from a neuron. First the brain gathers information from the receptors and spread it around it’s branch fibers‚ or dendrites. Next the information is sent to the soma‚ the neurons cell body‚ where it is combined with other information. Finally

From Tissues to organs Cells combine to form tissues and tissues combine to form organs. Cells combine to form four primary tissues: - Epithelial tissue - Connective tissue - Muscle tissue - Nerve tissue BACKGROUND:A tissue is a group of cells that have a similar

break between the nerve and muscle to activate contraction. The progression in which signals are sent from motor neurons to skeletal muscle fibres to warrant movement of muscles is called neuromuscular junction (Etherington & Hong‚ 2011). Motor neurons‚ Schwann cells‚ muscle fibres and kranocytes are all the different cell types that make up the neuromuscular junction. Motor neurons send out axons to skeletal muscles where an action potential is passed along the axons. The axons form a synaptic

much of his motor ability but has lost some of his sensory function. What factors are involved that affect the regeneration of Brett’s neurons and neuron function? Clinical answer: For regeneration of neurons (getting sensory feeling back)‚ his type of injury involves the PNS neurons that were involved‚ rather than CNS neurons‚ so the chances of his neurons regenerating increase. Nerve generation depends on location of the injury‚ inflammatory responses‚ and the process of scarring. When
