These nodes represent the points of discontinuity between individual Schwann cells or oligodendrocytes arrayed along the nerve fiber. In myelinated axons, current hops between nodes and travels much faster compared to an unmyelinated axon of similar diameter. Objective: student will be able to describe the structure and function of neurons for transmitting messages.

d. dendrite Myelin sheath provides support to the neuron and works as an insulator and conductor. There is a periodic gap after each Schwann cell throughout the axon. These gaps are known as the nodes of Ranvier where the electrical signal or impulse get recharged before entering into the next Schwann cell.

The Nissl bodies that produce the neuronal proteins are absent in the axonal region. [3] The myelin sheath is an insulating, and protective covering of the axon of a neuron. The myelin sheath is made up of the non-electrically conducting neuroglia or glial cell.

A nerve cell (neuron) showing axon and dendrites. The myelin sheath is fatty material that covers, insulates and protects nerves of the brain and spinal cord.

largest part of the brain, wrinkly part. frontal lobe. Front of the brain, associated with reasoning, planning, parts of speech, movement, emotions, and problem solving. motor strip. The axon, both in the vertebrates and invertebrates are often covered with a sheath called the myelin sheath such fibers are called myelinated fiber while those which are not covered are called non-myelinated fiber. Dendrites are always non-myelinated. 2007-05-17 · The myelin sheath is a layer of lipids which act as insulation to the axon.

Myelin develops along a nerve axon in direct response to the use of that nerve: The more you activate that particular nerve, the more myelin it will develop. Much of brain development, particularly in adolescence and early adulthood, has to do with the growth of myelin on nerve axons. Myelin makes up the “white matter’ of the brain.
