Harderian gland in dogs

The Harderian gland is an anterior orbital gland usually associated with the nictitating membrane, and produces and secretes a variety of substances to the eye, depending upon the species[GO]. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the Harderian gland is

The Harderian gland is an anterior orbital gland usually associated with the nictitating membrane, and produces and secretes a variety of substances to the eye, depending upon the species[GO]. The atlas records it as a gland at the organ scale in the dog.

Where the Harderian gland is

It sits in the head, within the sensory 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 Harderian gland connects to

The atlas records 8 typed relationships for it, across 3 kinds of connection. part of anatomical structure, camera-type eye and exocrine system, and 1 more.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the Harderian gland. 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 recorded as Hardarian gland, Harder's gland, gland of Hardarian, glandula palpebra tertia profundus and deep gland of the nictitating membrane. Searching any of those names reaches this page.
