Problem:Myelin is a lipid-rich (fatty) substance formed in the central nervous system (CNS) by glial cells called oligodendrocytes, and in the peripheral nervous system (PNS) by Schwann cells. Myelin insulates nerve cell axons to increase the speed at which information (encoded as an electrical signal) travels from one nerve cell body to another (as in the CNS) or, for example, from a nerve cell body to a muscle (as in the PNS). The myelinated axon can be likened to an electrical wire (the axon) with insulating material (myelin) around it. However, unlike the plastic covering on an electrical wire, myelin does not form a single long sheath over the entire length of the axon. Rather, each myelin sheath insulates the axon over a single section and, in general, each axon comprises multiple long myelinated sections separated from each other by short gaps. Each myelin sheath is formed by the concentric wrapping of an oligodendrocyte or Schwann cell process around the axon.

Answer this question: the myelin sheath that covers many cns axons is formed by?
Solution:OK... The relevant information is: Each myelin sheath is formed by the concentric wrapping of an oligodendrocyte or Schwann cell process around the axon.
the concentric wrapping of an oligodendrocyte or Schwann cell process around the axon.

Problem:By 1966, the British government had come to the conclusion that it could no longer afford to govern what is now the United Arab Emirates. Much deliberation took place in the British parliament, with a number of MPs arguing that the Royal Navy would not be able to defend the Trucial Sheikhdoms. Denis Healey, who, at the time, was the UK Secretary of State for Defence, reported that the British Armed Forces were severely overextended, and in some respects, dangerously under-equipped to defend the Sheikhdoms. On 24 January 1968, British Prime Minister Harold Wilson announced the decision to end the treaty relationships with the seven Trucial Sheikhdoms which had been, together with Bahrain and Qatar, under British protection. The British decision to withdraw was reaffirmed in March 1971 by Prime Minister Edward Heath.
