mucosa-associated lymphoid tissue in dogs

Diffuse system of small concentrations of lymphoid tissue found in various sites of the body such as the gastrointestinal tract, thyroid, breast, lung, salivary glands, eye, and skin[WP]. Mucosal-associated lymphoid tissue is typically found as nodules associated with mucosal epithelia with distinct internal structures including B- and T-zones for the activation of lymphocytes[GO]. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the mucosa-associated lymphoid tissue is

Diffuse system of small concentrations of lymphoid tissue found in various sites of the body such as the gastrointestinal tract, thyroid, breast, lung, salivary glands, eye, and skin[WP]. Mucosal-associated lymphoid tissue is typically found as nodules associated with mucosal epithelia with distinct internal structures including B- and T-zones for the activation of lymphocytes[GO]. The atlas records it as a lymphatic at the organ scale in the dog.

Where the mucosa-associated lymphoid tissue is

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

What the mucosa-associated lymphoid tissue connects to

The atlas records 6 typed relationships for it, across 3 kinds of connection. a kind of lymphoid tissue.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the mucosa-associated lymphoid tissue. 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.

Questions

Where is the mucosa-associated lymphoid tissue?

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

What does the mucosa-associated lymphoid tissue connect to?

A kind of: lymphoid tissue.

Is the mucosa-associated lymphoid tissue 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.
