Ax-‚ axle: axon – cylindrical nerve process that carries impulses away from a neuron cell body. Dendr-‚ tree: dendrite – branched nerve process that serves as the receptor surface of a neuron. Funi-‚ cord‚ rope: funilicus – funiculi of spinal cord or bundle of nerve fibers. Gangli-‚ knot: ganglia – deliver information to the body -lemm‚ rind or peel: neurilemma – sheath that surrounds

nervous system includes all nervous tissue in the body -Neural tissue contains two types of cells: 1) neurons (10% of all neurons‚ conduct nerve impulses) 2) neuroglia (support neurons) -We have 100 billion neurons -Organs of the nervous system: brain‚ spinal cord‚ sensory receptors of sense organs (eyes‚ ears‚ etc.)‚ and nerves (connects the nervous system with other systems‚ bundle of neurons that relay information) -Functions of the nervous system: 1) sensory input- everything coming in (smells

The brain is one of the most vital and complex organs in the human anatomy‚ enabling us to act and react to situations in our everyday lives. It is in the nervous system of all living things‚ with the exception of some invertebrates. The ability to hear‚ see‚ taste and smell all originate from the brain‚ making it an organ us humans cannot live without. The brain serves a human being a variety of functions. One of those functions the brain serves is Information Processing. Information processing

cell body to other neurons. Dendrite: short‚ highly branched fibers that carry signals toward the cell body of a neuron. Central nervous system (CNS): the division of the nervous system that includes the brain and the spinal cord. Sensory neurons/afferent neurons: send information from sensory receptors (in the eyes‚ ears‚ nose‚ tongue‚ and skin) TO the central nervous system.

At the age of three years‚ Jody Miller was having difficulties in moving the left side of her body and began experiencing severe epileptic seizures. She was soon diagnosed with Rasmussen’s Syndrome; a neurodegenerative syndrome including symptoms such as slight paralysis‚ epileptic seizures‚ decline in cognition and behaviour. On the recommendation of a paediatric neurologist‚ Miller underwent an operation that would remove the right hemisphere of her brain‚ known as a hemispherectomy‚ in an attempt
