Ultrastructural parameters of motor nerve terminals in Syb1lew/lew and control mice
| Syb1lew/lew (n = 50) | Control (n = 50) | |
|---|---|---|
| Nerve terminal area (μm2) | 3.10 ± 0.37 | 3.34 ± 0.50 |
| Nerve terminal perimeter (μm) | 8.17 ± 0.56 | 8.50 ± 0.67 |
| Synaptic contact length (μm) | 3.76 ± 0.28 | 3.55 ± 0.36 |
| Synaptic vesicle number (per terminal) | 180 ± 21 | 173 ± 17 |
| Synaptic vesicle density (per μm2) | 66.3 ± 4.1 | 72.8 ± 6.5 |
| Active zone number (per terminal) | 1.2 ± 0.1 | 1.1 ± 0.1 |
| Docked synaptic vesicle number (per terminal) | 3.6 ± 0.3 | 3.4 ± 0.3 |
The data are presented as mean ± SEM. A total of 100 nerve terminals (50 control, 50 Syb1lew/lew) from 4 pairs of Syb1lew/lew and control mice were analysed. No statistical difference (Student's t test) was found between Syb1lew/lew and control mice.
