What does a skull do on horse?

It seems like you're asking about the skull of a horse. It's not something a horse "does," but rather a vital part of its body. Here's what the skull does for a horse:

* Protects the brain: The skull is a hard, bony structure that encases the brain, protecting it from injury.

* Supports the face: The skull provides the framework for the horse's face, giving it shape and supporting the teeth, eyes, nose, and other facial structures.

* Connects to the spine: The skull connects to the horse's spine, allowing for movement of the head and neck.

* Houses the senses: The skull houses the organs of smell, sight, and hearing, allowing the horse to experience the world around it.
