Long Bone Structure and Function

This video tutorial reviews the parts of a long bone, focusing on the epiphysis, diaphysis, and marrow cavity. It explains the differences between compact and spongy bone, highlighting their functions and locations. The video emphasizes the importance of understanding these structures for tests, advising students not to confuse the femur with the parts of a long bone. The tutorial concludes with a review and test preparation tips.

What is the main focus of the test regarding the long bone structure?

• Identifying the femur

• Naming the parts of the femur

• Understanding the structures of a long bone

• Describing the function of the femur

What are the ends of a long bone called?

• Diaphysis

What is the shaft of a long bone known as?

• Epiphysis

• Diaphysis

• Spongy bone

• Marrow cavity

What is found within the marrow cavity of a long bone?

• Blood stem cells

• Fatty tissue

• Compact bone

• Spongy bone

Why is the marrow cavity important for the bone?

• It makes the bone lighter and stronger

• It stores calcium

• It makes the bone heavier

• It provides a space for blood vessels

Where is compact bone primarily located in a long bone?

• Lining the outside of the diaphysis

• Inside the marrow cavity

• In the epiphysis

• In the spongy bone

What characteristic does spongy bone have?

• It is found only in the diaphysis

• It is porous like a sponge

• It is filled with fatty tissue

• It is dense and solid

What color would the spongy bone appear if it were from a live femur?

• Red

• Blue

• White

• Yellow

What is the most abundant type of blood cell produced in the spongy bone?

• Stem cells

• Red blood cells

• Platelets

• White blood cells

What should students do to prepare for the test on long bone structure?

• Review the video and take practice tests

• Memorize the parts of the femur

• Learn about bone diseases

• Focus on the function of the femur
