Consider the following statements regarding connective tissues: Statement I: All connective tissues contain cells, fibers, and an extracellular matrix. Statement II: Dense irregular connective tissue has fibers arranged in parallel bundles, providing great tensile strength in unidirectional stress. Statement III: Adipose tissue is a type of loose connective tissue specialized to store fats. Statement IV: Cartilage is a specialized connective tissue with a solid, pliable matrix; osteocytes are fluid-filled spaces within its matrix. Which of the above statements are correct?

A cross-section of a mammalian artery is shown. Which feature represents the tunica intima? [Diagram description: A cross-section of a blood vessel with three distinct layers. The outermost layer is thick and fibrous. The middle layer is muscular and elastic. The innermost layer is a thin lining directly adjacent to the lumen. The innermost layer is labeled as 'tunica intima'.]
