Blood Supply of Long Bones Quiz

What is the primary function of the nutrient artery in long bones?

• To supply blood to the periosteum

• To connect with the epiphyseal arteries

• To form endarterial loops

• To provide nutrients to the bone marrow

Where do the metaphyseal arteries primarily enter the long bones?

• Under the articular cartilage

• At the middle of the shaft

• Near the epiphyseal line

• Through the nutrient foramen

How do epiphyseal arteries contribute to the blood supply of long bones?

• By anastomosing with metaphyseal arteries

• By forming a plexus over the periosteum

• By supplying the bone marrow directly

• By entering through the nutrient foramen

What is the origin of the periosteal arteries?

• From the epiphyseal arteries

• From the muscular arteries

• From the nutrient artery

• From the central venous sinus

Which arteries form a plexus over the periosteum?

• Nutrient arteries

• Periosteal arteries

• Epiphyseal arteries

• Metaphyseal arteries
