Question

lo 4.1. an articulation, or joint, is defined as ________. a mobile union of two or more bones any point where two bones meet any two pieces of connective tissue joined to one another any point a tendon crosses over a bone a fixed union of two or more bones

Explanation:

An articulation or joint is defined as any point where two bones meet. This includes both movable and immovable junctions between bones. The other options are incorrect as they do not fully or accurately define a joint. Tendons crossing over a bone or connective - tissue junctions are not the definition of a joint, and the definitions of mobile or fixed unions of bones are too restrictive as joints can be either mobile or immobile.

Answer:

any point where two bones meet
