- An axon (from Greek ἄξων áxōn, axis), or nerve fiber (or nerve fibre: see spelling differences), is a long, slender projection of a nerve cell, or neuron, in vertebrates, that typically conducts electrical impulses known as action potentials away from the nerve cell body. The function of the axon is to transmit information to different neurons, muscles, and glands. In certain sensory neurons (pseudounipolar neurons), such as those for touch and warmth, the axons are called afferent nerve fibers and the electrical impulse travels along these from the periphery to the cell body and from the cell body to the spinal cord along another branch of the same axon. Axon dysfunction can be the cause of many inherited and acquired neurological disorders that affect both the peripheral and central neurons. Nerve fibers are classed into three types – group A nerve fibers, group B nerve fibers, and group C nerve fibers. Groups A and B are myelinated, and group C are unmyelinated. These groups include both sensory fibers and motor fibers. Another classification groups only the sensory fibers as Type I, Type II, Type III, and Type IV.
- Connecticut (Wikipedia)
Connecticut (/kəˈnɛtɪkət/ kə-NET-ik-ət) is the southernmost state in the New England region of the Northeastern United States. As of the 2020 United States census, Connecticut was home to over 3.6 million residents, its highest decennial count ever, growing every decade since 1790. The state is bordered by Rhode Island to its east, Massachusetts to its north, New York to its west, and Long Island Sound to its south. Its capital is Hartford, and its most populous city is Bridgeport. Historically, the state is part of New England as well as the tri-state area with New York and New Jersey. The state is named for the Connecticut River which approximately bisects the state. The word Connecticut is derived from various anglicized spellings of Quinnetuket, a Mohegan-Pequot word for “long tidal river”.
