Axonal | Definition of Axonal at Dictionary.com neuropathy [noo͡-rop´ah-the] any of numerous functional disturbances and pathologic changes in the peripheral nervous system. The etiology may be known (e.g., arsenical, diabetic, ischemic, or traumatic neuropathy) or unknown. encephalopathy and myelopathy are corresponding terms relating to involvement of the brain and spinal cord. The term is also

The Axonal Growth Cone - Neuroscience - NCBI Bookshelf The conus medullaris is the bundled, tapered end of the spinal cord nerves. Situated near the first two lumbar vertebrae, the conus medullaris ends at the cauda equina, a bundle of spinal nerves and nerve roots.Consequently, problems with the conus medullaris often affect the cauda equina. Conus medullaris syndrome is a secondary form of spinal cord damage resulting from injuries to the lumber

Drosophila as a genetic and cellular model for studies on Diffuse axonal injury (DAI) is a brain injury in which scattered lesions in white matter tracts as well as gray matter occur over a widespread area. DAI is one of the most common and devastating types of traumatic brain injury and is a major cause of unconsciousness and …

Neurofisiología de las Sinapsis. O transporte axoplásmico, tamén chamado transporte axonal, é un proceso de transporte celular responsable de mover mitocondrias, lípidos, vesículas sinápticas, proteínas, e outros compoñentes celulares desde ou ata o corpo celular das neuronas a través da porción de citoplasma contida no seu axón (denominada axoplasma).Os axóns das neuronas poden ter 1.000 ou 10.000 veces a

¿Qué es el cono axónico? – Curiosoando One of the most fascinating processes during nervous system development is the establishment of stereotypic neuronal networks. An essential step in this process is the outgrowth and precise navigation (pathfinding) of axons and dendrites towards their synaptic partner cells. This phenomenon was first described more than a century ago and, over the past decades, increasing insights have been

Pharmacology Overview of the nervous system. Flashcards Multifocal motor neuropathy (MMN) is characterised by asymmetrical weakness and muscle atrophy, in the arms more than the legs, without sensory loss. Despite a beneficial response to treatment with intravenous immunoglobulins (IVIg), weakness is slowly progressive. Histopathological studies in MMN revealed features of demyelination and axon loss.

Psicología general y salud mental (página 4) - Monografias.com El cono axónico es una zona ensanchada del axón situada entre este y el soma. La membrana citoplasmática del cono axónico presenta mayor densidad de canales iónicos voltaje-dependientes que la membrana del soma, lo que es muy importante para generar los potenciales de acción.

Drosophila as a genetic and cellular - Neural Development The Axonal Growth Cone. Among the many extraordinary features of nervous system development, one of the most fascinating is the ability of growing axons to navigate through a complex cellular embryonic terrain to find appropriate synaptic partners that may be millimeters or even centimeters away.

Axonal neuropathy | definition of axonal neuropathy by cono axonal In 1880, Ramón y Cajal observed and named the growth cone ("cono de crecimiento") as the motile structure leading the axonal extension. During development, the growth cone leads the elongating axon navigating through the complex environment of developing tissues, senses and responds to a variety of attractive or repulsive cues by turning

Anatomía de la médula espinal - SlideShare cono axonal The axonal initial segment (AIS) is a structurally and functionally separate microdomain of the axon. One function of the initial segment is to separate the main part of an axon from the rest of the neuron; another function is to help initiate action potentials. Both of
