axon (redirected from Axonal nerve)

axon /ax·on/ (ak´son)

1. that process of a neuron by which impulses travel away from the cell body; at the terminal arborization of the axon, the impulses are transmitted to other nerve cells or to effector organs. Larger axons are covered by a myelin sheath.ax´onal

2. vertebral column.

ax·on (ksn) or ax·one (-sn)

n.

The usually long process of a nerve fiber that generally conducts impulses away from the body of the nerve cell.

axon·al (ks-nl, k-snl) adj.

---

Axon

A process of a neuron that conducts impulses away from the cell body. Axons are usually long and straight.

axon

[ak′son]

Etymology: Gk, axle

an extension, usually long and slender, of a neuron capable of conducting action potentials or self-propagating nervous impulses. Axons can conduct impulses over great distances away from the cell body. Only ends of axons (terminals) can release neurotransmitters and stimulate other neurons/effectors. Also called axone [ak′-sōn] , axis cylinder. Compare dendrite. See also action potential, neurotransmitter.

axon (ak´son),

n an extension of a nerve cell body that conducts impulses away from the cell. Generally there is only one axon to a cell.

---

axon

the process of a nerve cell along which impulses travel away from the cell body. It branches at its termination, forming synapses at other nerve cells or effector organs. Many axons are covered by a myelin sheath formed from the cell membrane of a glial or Schwann cell.

---

axon hillock

the elevation on the perikaryon from which the axon emerges.

axon reflex

a nerve impulse conducted through nerve pathways limited to the single axon, without the participation of a nerve cell or synapse. Not a true reflex.

axon telodendrion

extensive terminal branches of the axon before terminating on the effector organ.

axon terminals

the axonal structure capable of forming a synapse with another axon.

axon 

The threadlike process of a neuron which conducts nerve impulses from the cell body to the neuron's ending (bouton) where it is transmitted via a synapse to another neuron, muscle or gland. Syn. nerve fibre (when it is sheathed). See neuron; synapse.
