## PNS – Nervi spinales (spinalnerver)
## PNS - Nervi spinales (spinalnerver)
### Ursprung
- 31 par spinalnerver (C1–C8, T1–T12, L1–L5, S1–S5, Co1).
- 31 par spinalnerver (C1-C8, T1-T12, L1-L5, S1-S5, Co1).
- Bildas av **radix anterior** (motoriska efferenter) och **radix posterior** (sensoriska afferenter med ganglion spinale).
- Dorsalrotsganglier innehåller pseudounipolära neuron omgivna av [[Satellitcell|satellitceller]].
### Förgrening
- Kort spinalnerv delar sig i **ramus anterior** (plexa, perifera nerver) och **ramus posterior** (ryggens muskler/dermatom).
- Rami communicantes kopplar till [[ANS|sympatiska kedjan]].
- Plexa: cervikal (C1–C4), brachial (C5–T1), lumbal (L1–L4), sakral (L4–S4).
- Plexa: cervikal (C1-C4), brachial (C5-T1), lumbal (L1-L4), sakral (L4-S4).
### Funktion
