👉 In biology, myelin is a specialized layer of nerve cells in the brain and spinal cord that helps to transmit electrical signals. It's composed of proteins called myelin oligomere (MO) molecules arranged in an array-like structure. Myelin has two main functions:
1.
Transmission
: The transmission of electrical impulses between neurons.
2.
Protection
: It protects nerve cells from damage and allows them to communicate effectively.
Myelins are also involved in the formation of synapses
