phrenic nerve

A nerve that arises from the caudal cervical nerves and is primarily the motor nerve of the diaphragm but also sends sensory fibers to the pericardium. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the phrenic nerve is

A nerve that arises from the caudal cervical nerves and is primarily the motor nerve of the diaphragm but also sends sensory fibers to the pericardium. The atlas records it as a nerve at the organ scale in the human body.

Where the phrenic nerve is

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

What the phrenic nerve connects to

The atlas records 6 typed relationships for it, across 6 kinds of connection. part of nerve of cervical vertebra.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the phrenic 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

Also recorded as diaphragmatic nerve, nervus phrenicus and phrenic. Searching any of those names reaches this page.

Questions

Where is the phrenic nerve?

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

What does the phrenic nerve connect to?

Part of: nerve of cervical vertebra.

Is the phrenic nerve the same in other species?

Leumas holds the same relationship vocabulary for every species it carries, so where another dataset records this structure you can put the two side by side on /compare.
