This is an introductory course on how MIND arises from the brain. We will learn structural and functional organization, basic neurology and terms which lay the ground work for conceptualization of mind.
The NERVOUS SYSTEM lacks connective tissue and bone, however, the skull and vertebral canal act as an exoskeleton. The glial cellular organization of the nervous system comprises an internal skeleton that supports neurons metabolically, functionally and structurally. Astrocytes and oligodendroglia are supporting cells in the CNS while satellite cells, connective tissue and Schwann cells are supporting cells in the PNS.
Glia in the CNS and PNS form myelin wrappings of neuronal axons. Oligodendroglia of the CNS and Schwann cells of the PNS interact with neurons in different ways to produce myelination of axons. The role of myelin is to speed action potential conduction on axons.
