LEVELS OF ORGANIZATION OF NERVOURS SYSTEM: NEURONS: * STRUCTURE AND FUNCTION: Specialized cell transmitting nerve impulses; a nerve cell. Neurons have specialized projections called dendrites and axons. Dendrites bring information to the cell body and axons take information away from the cell body. Neurons communicate with each other through an electrochemical process. Information is transmitted to the receiving cell at junctions via chemical messengers called neurotransmitters. At this juncture

Embryonic stem cell are by most scientists and researchers to cure spinal cord injuries‚ multiple sclerosis‚ diabetes‚ Parkinson’s disease‚ cancer‚ Alzheimer’s diseases‚ heart disease‚ hundreds of rare immune system and genetic disorders and much more. These Embryonic Stem cell have the ability to form doll adult cell types

nervous system and the peripheral nervous system. The central nervous system is comprised of the brain and the spinal cord. The peripheral nervous system links the central nervous system with the body ’ s sense receptors‚ muscles‚ and glands. Information travels in the nervous system via three types of neurons. Sensory neurons send information from the senses to the brain and spinal cord‚ which process the information. Interneurons enable the nervous systems internal communications. Motor neurons

salary for a surgeon of this type is in the area of about $395‚000 but with six years of experience this can grow to about $590‚000. Neurosurgeons specialize in the treatment of trauma ‚ tumors‚ vascular disorders‚ brain and spinal infections‚ strokes‚ and degenerative spinal disorders. In order to be a neurosurgeon there are many different schooling requirements. First off‚ you need to have a bachelor’s degree. Then afterward‚ you will need to attend medical school.

Vertebrate Anatomy Room # 123 The Origin of Chordates Reginald Bushner February 15‚ 2013 1 Abstract The word chordate originates from the word chorda or cord. Chordates are a very large group of animals with backbones. These animals have backbones or spines and inside are spinal cords‚ and an internal skeleton as part of their nervous system. It is believed that chordates have originated from invertebrates. It is difficult to determine from which invertebrate group

Framework of the Skull The bony framework of the head‚ called the skull‚ is subdivided into two parts: the cranium and the facial portion. Refer to Figures 3-5 through 3-8‚ which show different views of the skull‚ as you study the following descriptions. Color-coding of the bones will aid in identification as the skull is seen from different positions. Cranium This rounded chamber that encloses the brain is composed of eight distinct cranial bones. * The frontal bone forms the forehead‚ the anterior

The Biology of Mind Neuron Communication Neuron is a nerve cell‚ basic building block our nerve system Neurons consists in: Dendrites : neurons bushy branches and it listens Axons: Tube that passes the messages and it speaks – transmit Action potential : is a neural impulse‚ brief electrical charge that travels down an axon. Threshold: is the level of stimulation required to trigger a neural impulse Myelin Sheath covers an axon and some neurons Synapse : is the junction

The dorsal division receives bilateral upper motor neuron input (i.e. from both sides

preganglionic neurons in the spinal cord. The presence of numerous preganglionic sympathitic neurons in the grey matter of the spinal cord produces the lateral horns. The lateral horns are just postlateral to the ventral horns that house somatic motor neurons. Parasympathetic preganglionic neurons in the sacral cord are far less abundant than the comprabale sympathetic neurons in the thoracolumbar regions‚ and lateralhorns are absent in the sacral regionof the spinal cord. 4.

There are many treatments a patient needs before they even step foot in a hospital such CPR‚ breathing assistance‚ epinephrine shots‚ spinal stabilization‚ and many more. Before any person can learn these techniques‚ they must first master three fundamentals of the emergency medical system. Education is important in the emergency medical system because workers must know the basics of
