scalene muscle

Any of the three pairs of muscles in the lateral neck, namely the scalenus anterior, scalenus medius, and scalenus posterior. They are innervated by the spinal nerves C4-C8[WP]. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the scalene muscle is

Any of the three pairs of muscles in the lateral neck, namely the scalenus anterior, scalenus medius, and scalenus posterior. They are innervated by the spinal nerves C4-C8[WP]. The atlas records it as a muscle at the organ scale in the human body.

Where the scalene muscle is

It sits in the neck, within the muscular system. Not positioned individually, and containment is not asserted either. Drawn near structures of the same kind, which is a weak claim about location.

What the scalene muscle connects to

The atlas records 6 typed relationships for it, across 4 kinds of connection. a kind of muscle of neck and muscle of vertebral column.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the scalene muscle. 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 scalene muscles, scalenus muscle, lateral cervical muscle, lateral cervical muscles, lateral vertebral muscle and m scalenus, and 5 more. Searching any of those names reaches this page.

Questions

Where is the scalene muscle?

It sits in the neck, within the muscular system. Not positioned individually, and containment is not asserted either. Drawn near structures of the same kind, which is a weak claim about location.

What does the scalene muscle connect to?

A kind of: muscle of neck and muscle of vertebral column.

Is the scalene muscle 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.
