| Name: | axon |
|---|---|
| Synonyms: | |
| Definition: | The long process of a neuron that conducts nerve impulses, usually away from the cell body to the terminals and varicosities, which are sites of storage and release of neurotransmitter. |

| Name: | has fewer parts of type |
|---|---|
| Synonyms: | decreased number of, has decreased number of, has fewer physical parts of type |
| Definition: | The bearer of this quality has_part < n AND has_part > 0 of the indicated entity type, where n is the normal amount for a comparable organism. Note that the bearer of the quality is the whole, not the part. Formally: If a bearer entity e has fewer parts of type X at time t, then the number of instances x of X at t such that x part_of e is < n, where n is either the normal number for comparable entities, or n is stated explicitly. |

| Name: | myelin sheath |
|---|---|
| Synonyms: | astrocyte sheath, oligodendrocyte myelin sheath, Schwann cell myelin sheath |
| Definition: | An electrically insulating fatty layer that surrounds the axons of many neurons. It is an outgrowth of glial cells: Schwann cells supply the myelin for peripheral neurons while oligodendrocytes supply it to those of the central nervous system. |
