Nerve Supply of the Lower
Limb
The lumbo-sacral plexus
Learning Outcomes
You should be able to…
• Explain where the lumbar and sacral plexuses
arise
• Describe the distribution of all the nerves
• Describe the course of the major nerves and
identify where each is vulnerable to injury
• Explain and use basic clinical terminology
related to nerve damage
• Use basic anatomical principles to predict the
effects of damage to nerve roots and peripheral
nerves
