Blood Supply of Long Bones Quiz

What is the primary reason long bones require multiple arterial sources?

• To support muscle attachment

• To increase bone length

• To enhance bone density

• To provide sufficient nourishment

Through which structure does the nutrient artery enter the bone?

• Epiphyseal plate

• Nutrient foramen

• Metaphysis

• Periosteum

What is the main function of the nutrient artery?

• Supply the periosteum

• Supply the epiphyseal plate

• Supply the medullary cavity and inner 2/3 of the cortex

• Supply the outer 1/3 of the cortex

What mnemonic helps remember the growing ends of bones?

• To the elbow I go, from the knee I flee

• To the wrist I go, from the ankle I flee

• To the hip I go, from the shoulder I flee

• To the shoulder I go, from the hip I flee

Which ends of the bones are considered the growing ends in the upper limb?

• Upper end of femur and lower end of tibia

Where are periosteal arteries especially numerous?

• Beneath the skin

• Beneath muscular and ligamentous attachments

• Inside the medullary cavity

• Around the epiphyseal plate

What part of the cortex do periosteal arteries supply?

• Outer 1/3

• Middle 1/3

• Entire cortex

From where are the epiphyseal arteries derived?

• Nutrient artery

• Periosteal arteries

• Periarticular vascular arcades
