Bezos is also willing to cannibalize his own companies: Amazon spent nearly $1 billion to acquire shoe retailer Zappos in 2009, but its Amazon shoe site competes directly with Zappos. As well, Bezos is adept both at changing the subject to one of his choosing and at crafting a reality that suits his purposes.
Fibroblasts produce three types of connective tissue fibers: collagenous fibers, elastic fibers, and reticular fibers. Of these, collagenous and elastic fibers are the most abundant. Fibroblasts produce three types of connective tissue fibers: collagenous fibers, elastic fibers, and reticular fibers.
A nerve fiber may be myelinated and/or unmyelinated. In the central nervous system (CNS), myelin is produced by oligodendroglia cells. Schwann cells form myelin in the peripheral nervous system (PNS). Schwann cells can also make a thin covering for an axon which does not consist of myelin (in the PNS).A peripheral nerve fiber consists of an axon, myelin sheath, Schwann cells and its endoneurium.There are no endoneurium and Schwann cells in the central nervous system.or example, the olfactory nerve fibers are short and without myelin, but the optic nerve fibers are myelinated (the olfactory and optic nerves are considered as a parts of the CNS, while other cranial nerves are a component of the PNS). A bundle of nerve fibers constitutes a tract in the central nervous system.
