Monofilament wigs are much more comfortable, especially for those with sensitive scalps. Instead of a cloth fabric, monofilament wigs use ultra thin, breathable gauze or silicon material. The breathable polyester or nylon mesh blends with the wearer's scalp color creating a realistic, undetectable look.
â¢ Axons usually carry information away from the cell body, while dendrites bring information to the cell body. â¢ Axons have myelin sheaths and nodes of Ranvier, whereas dendrites donât. â¢ Myelinated axons conduct impulses faster than dendrites. â¢ Dendrites have ribosomes and axons donât. â¢ Axons are branched far from the cell body, whereas dendrites are branched near the cell body.
1 Dendrites are specialized extensions of the cell body. 2  They function to obtain information from other cells and carry that information to the cell body. 3  Many neurons also have an axon, which carries information from the soma to other cells, but many small cells do not. The axon carries messages in the form of action potentials from the cell body to its endfeet, which synapse upon other neurons or effector organs. 2  Cells with long axons are called principal neurons. 3  These cells establish the pattern of connectivity within the nervous system.
