Document Summary
Neuroanatomy: study related to structures of the nervous system. Neurophysiology: study related to functions of the nervous system. Neurolinguistics: study related to structures and functions of the nervous system which help with language skills. Psycholinguistics: study of cognitive processes which help in development, processing, and production of human language. Magnetic resonance imaging (mri): nonradioactive technique that helps in studying brain structures based on magnetic fields. Functional magnetic resonance imaging (fmri): special type of mri where blood flow within the brain areas is studied in response to external stimuli. Structural and functional unit of the nervous system: consists of: Soma (cell body): contains the nucleus and cytoplasm. Dendrites: type of nerve fibers, which can either be myelinated or unmyelinated. Axon: type of nerve fiber which can either be myelinated or unmyelinated. Myelin: thin layer of consisting of white protective fatty material. Schwann cells: myelin sheath covering peripheral nervous system. Nodes of ranvier: small gaps which are located in-between the.
