Final answer:
The lower eyelid rolling outward away from the eye is referred to as ectropion. Conditions like ectropion are distinct from other bodily movements like lateral excursion or abduction at the shoulder joint.
Step-by-step explanation:
The position of the lower eyelid when it is rolling outward away from the eye is known as ectropion. This condition can cause dryness, irritation, and potential damage to the surface of the eye, as the eyelid is not providing adequate protection and lubrication to the eye. In terms of physiology and body movements, it is important to note distinctions such as the lateral excursion, which is the side-to-side movement of the mandible, and movement at the shoulder joint like abduction, where the upper limb moves laterally away from the body.
