Question

what type of tissue is made of cylinders called osteons or haversian systems? a compact bone b hyaline cartilage c adipose tissue d spongy bone

Explanation:

Compact bone is characterized by its structural unit, the osteon (also known as the Haversian system). Osteons are cylindrical structures that contain a central Haversian canal surrounded by concentric layers of bone matrix called lamellae. Hyaline cartilage is a smooth - surfaced cartilage, adipose tissue is fat - storing tissue, and spongy bone has a different microstructure with trabeculae instead of osteons.

Answer:

A. Compact bone
