sciatic nerve in dogs

A large nerve that supplies nearly the whole of the skin of the leg, the muscles of the back of the thigh, and those of the leg and foot. It begins in the lower back and runs through the buttock and down the lower limb. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the sciatic nerve is

A large nerve that supplies nearly the whole of the skin of the leg, the muscles of the back of the thigh, and those of the leg and foot. It begins in the lower back and runs through the buttock and down the lower limb. The atlas records it as a nerve at the organ scale in the dog.

Where the sciatic nerve is

It sits within the nervous system. Positioned deliberately as part of this species body plan.

What the sciatic nerve connects to

The atlas records 10 typed relationships for it, across 6 kinds of connection. part of lumbosacral nerve plexus.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the sciatic nerve. Only a minority of structures carry those edges here, so an empty answer means nothing has been recorded — not that there is nothing to record.

Also called
