Answer:
Myelination
Explanation:
The covering of myelin around the axons is called the myelin sheath. This myelin sheath helps in transfer of information faster and also in complex processes of the brain. The process of myelination begins in the PNS (peripheral nervous system).
The myelinated section are seperated from each other with a gap called nodes of ranvier. Glial cells (oligodendrocytes) forms the myelin sheath in the central nervous system and schwann cells (glial cells) forms the myelin sheath in peripheral nervous system. The propagation of electrical impulse in the myelinated fibers is by saltatory conduction that is from one node to another.
<span>Lactation is different between monotremes and therian mammals because monotremes are oviparous and have cloaca . Oviparous means they lay eggs, and generally animals that lay eggs do not nurse their young or lactate. Therian mammals give live birth, these are the animals that use breast milk to nurse their young.</span>

Wiskott-Aldrich syndrome is linked with low immunoglobulin G (IgG) and immunoglobulin M (IgM) levels, with normal-to-high immunoglobulin E (IgE) and immunoglobulin A (IgA) levels. Though, young babies in exact may not display classic immunoglobulin irregularities because Wiskott-Aldrich syndrome is linked with attrition in immunologic functions.
