sclerotome in dogs

Ventral somitic compartment that is a precursor of the axial skeleton[XAO]. Sclerotomes eventually differentiate into the vertebrae and most of the skull. The caudal (posterior) half of one sclerotome fuses with the rostral (anterior) half of the adjacent one to form each vertebra. From their initial location within the somite, the sclerotome cells migrate medially towards the notochord. These cells meet the sclerotome cells from the other side to form the vertebral body. From this vertebral body, sclerotome cells move dorsally and surround the developing spinal cord, forming the vertebral arch[WP]. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the sclerotome is

Ventral somitic compartment that is a precursor of the axial skeleton[XAO]. Sclerotomes eventually differentiate into the vertebrae and most of the skull. The caudal (posterior) half of one sclerotome fuses with the rostral (anterior) half of the adjacent one to form each vertebra. From their initial location within the somite, the sclerotome cells migrate medially towards the notochord. These cells meet the sclerotome cells from the other side to form the vertebral body. From this vertebral body, sclerotome cells move dorsally and surround the developing spinal cord, forming the vertebral arch[WP]. The atlas records it as a tissue at the tissue scale in the dog.

Where the sclerotome is

This dataset records no region or system for it. No positional evidence of any kind. Drawn outside the body so it can still be found and counted, never inside it.

What the sclerotome connects to

The atlas records 6 typed relationships for it, across 3 kinds of connection. a kind of anatomical structure and mesenchyme.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the sclerotome. 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 sclerotome?

This dataset records no region or system for it. No positional evidence of any kind. Drawn outside the body so it can still be found and counted, never inside it.

What does the sclerotome connect to?

A kind of: anatomical structure and mesenchyme.

Is the sclerotome 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.
