👉 Myelencephala, also known as myelin sheath, is a type of nerve cell that forms around the axon terminals of neurons. It acts as a protective barrier between the neuron's axon and its dendrites, helping to prevent damage or injury to the nerve cells during transmission of signals from one neuron to another. The term "myelencephala" refers to this specialized layer of myelin in the brain and spinal cord.
