pharyngeal arch in dogs

One of a series of paired bulges that develop along the lateral walls of the foregut. The pharyngeal arches have developmental contributions from endoderm, mesoderm, and neural crest cells and are separated by anterior lateral endoderm out-pockets known as pharyngeal pouches. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the pharyngeal arch is

One of a series of paired bulges that develop along the lateral walls of the foregut. The pharyngeal arches have developmental contributions from endoderm, mesoderm, and neural crest cells and are separated by anterior lateral endoderm out-pockets known as pharyngeal pouches. The atlas records it as a tissue at the tissue scale in the dog.

Where the pharyngeal arch is

It sits within the digestive system. Only the system is known. The position shown carries almost no spatial information.

What the pharyngeal arch connects to

The atlas records 19 typed relationships for it, across 6 kinds of connection. part of anatomical entity, embryo and foregut, and 1 more.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the pharyngeal arch. 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 pharyngeal arches, branchial arch, arcus pharyngei and visceral arch. Searching any of those names reaches this page.

Questions

Where is the pharyngeal arch?

It sits within the digestive system. Only the system is known. The position shown carries almost no spatial information.

What does the pharyngeal arch connect to?

Part of: anatomical entity, embryo, foregut and organ.

Is the pharyngeal arch the same in other species?

This page describes the dog. The human record of the same structure sits beside it on /compare, over one shared model rather than two atlases built separately.
