| naked | 1. Having no clothes on; uncovered; nude; bare; as, a naked body; a naked limb; a naked sword. 2. Having no means of defense or protection; open; unarmed; defenseless. "Thy power is full naked." (Chaucer) "Behold my bosom naked to your swords." (Addison) 3. Unprovided with needful or desirable accessories, means of sustenance, etc.; destitute; unaided; bare. "Patriots who had exposed themselves for the public, and whom they say now left naked." (Milton) 4. Without addition, exaggeration, or excuses; not concealed or disguised; open to view; manifest; plain. "The truth appears so naked on my side, That any purblind eye may find it out." (Shak) "All things are naked and opened unto the eyes of him with whom we to do." (Heb. Iv. 13) 5. Mere; simple; plain. "The very naked name of love." (Shak) 6. <botany> Without pubescence; as, a naked leaf or stem; bare, or not covered by the customary parts, as a flower without a perianth, a stem without leaves, seeds without a pericarp, buds without bud scales. 7. Not having the full complement of tones; said of a chord of only two tones, which requires a third tone to be sounded with them to make the combination pleasing to the ear; as, a naked fourth or fifth. Naked bed, a bed the occupant of which is naked, no night linen being worn in ancient times. Naked eye, the eye alone, unaided by glasses, or by telescope, microscope, or the like. Naked-eyed medusa. <medicine> A nudibranch. <botany> Naked wood, a large rhamnaceous tree (Colibrina reclinata) of Southern Florida and the West Indies, having a hard and heavy heartwood, which takes a fine polish. Synonym: Nude, bare, denuded, uncovered, unclothed, exposed, unarmed, plain, defenseless. Origin: AS. Nacod; akin to D. Naakt, G. Nackt, OHG. Nacchot, nahhot, Icel. Nokvir, nakinn, Sw. Naken, Dan. Nogen, Goth. Naqas, Lith. Ngas, Russ. Nagii, L. Nudus, Skr. Nagna. Cf. Nude. Source: Websters Dictionary (01 Mar 1998) |

| naked virus | A virus consisting only of a nucleocapsid; i.e., one that does not possess an enclosing envelope. (05 Mar 2000) |
| axon | <cell biology> A long process of a neuron, that carries efferent (outgoing) action potentials from the cell body towards target cells. Each nerve cell has one axon, which can be over a foot long. A nerve cell communicates with another nerve cell by transmitting signals from the branches at the end of its axon. At the terminal end of the axon, the impulses are transmitted to other nerve cells or to effector organs. In the peripheral nervous system, the larger (myelinated) axons are surrounded by a myelin sheath formed by concentric layers of plasma membrane of the schwann cell. In the central nervous system, the function of the schwann cell is supplied by oligodendrocytes (oligodendroglia). See: dendrite. (03 Jul 1999) |
| axon degeneration | A type of peripheral nerve fibre response to insult, wherein axon death and subsequent breakdown occurs, with secondary breakdown of the myelin sheath associated; caused by focal injury to peripheral nerve fibres; often referred to as wallerian degeneration. Synonym: axon degeneration. (05 Mar 2000) |
| axon hillock | <cell biology> Tapering region between a neuron's cell body and its axon. This region is responsible for summating the graded inputs from the dendrites and producing action potentials if the threshold is exceeded. (12 Mar 1998) |
| axon loss polyneuropathy | A type of polyneuropathy in which axon degeneration is the sole/predominant feature; many aetiologies, particularly toxic and metabolic; on nerve conduction studies, affects amplitudes of the responses, but does not cause conduction slowing or block. Synonym: axonal polyneuropathy. (05 Mar 2000) |
| axon reflex | An effect brought about by the passage of the nerve impulses from a sensory ending to the effector organ along divisions of the nerve fibre without traversing a synapse, e.g., as in the vasodilation resulting from stimulation of the skin or the irritation of the conjunctiva; the reaction occurs even when the nerve fibre has been sectioned and thus isolated from the nervous centres. (05 Mar 2000) |
| axon terminals | The somewhat enlarged, often club-shaped endings by which axons make synaptic contacts with other nerve cells or with effector cells (muscle or gland cells). As isolated, by homogenizing brain or spinal cord, they contain acetylcholine and the related enzymes. Terminals contain neurotransmitters of various kinds, sometimes more than one. These can be demonstrated by chemical analysis and immunocytochemical methods. See: synapse. Synonym: axonal terminal boutons, end-feet, neuropodia, pieds terminaux, synaptic boutons, synaptic endings, synaptic terminals, terminal boutons, bouton terminaux. (05 Mar 2000) |
| giant axon | <biology> Extraordinarily large unmyelinated axons found in invertebrates. Some, like the squid giant axon, can approach 1 mm diameter. Large axons have high conduction speeds, the giant axons are invariably involved in panic or escape responses and may (e.g. Crayfish) have electrical synapses to further increase speed. Vertebrate axons with high conduction velocites are much narrower: they are myelinated, allowing saltatory conduction. (17 Dec 1997) |
| cervix of the axon | The constricted portion of the axon just before the myelin sheath begins. (05 Mar 2000) |
| squid giant axon | <physiology> Large axons, up to 1mm in diameter, that innervate the mantle of the squid. Because of their large size, many of the pioneering investigations of the mechanisms underlying resting and action potentials in excitable cells were done on these fibres. (10 Mar 1998) |
