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.
Key Points. 1  Dendrites are the tree-like structures in neurons that extend away from the cell body to receive messages from other neurons at synapses; not all neurons have dendrites. 2  Synapses enable the dendrites from a single neuron to interact and receive signals from many other neurons.
