Short bone
Flat bone
What is the correct anatomical term for the shaft or long portion of a bone like the humerus?
Epiphysis
Medullary cavity
Periosteum
Diaphysis
The vertebrae, which have complex shapes to perform specific functions like organ protection, are classified as:
Irregular bones
Long bones
Sesamoid bones
Short bones
What is the name of the thin layer of cartilage that covers the ends of bones where they meet to form a joint?
Compact bone
Periosteum
Articular cartilage
Spongy bone
The space within the diaphysis of a long bone that contains bone marrow is called the:

How does the primary purpose of long bones differ from that of short bones?
Long bones produce blood cells, while short bones store minerals.
Long bones provide stability, while short bones facilitate movement.
Long bones protect organs, while short bones are for muscle attachment.
Long bones support weight and facilitate movement, while short bones provide stability.
According to the provided text, the scapula (shoulder blade) can be classified under which two of the following categories?
Short and Irregular
Flat and Sesamoid
Flat and Irregular
Long and Flat
What is the specific function of sesamoid bones like the patella?
To connect bone directly to another bone
To provide a smooth surface for articulation
To produce synovial fluid for lubrication
To increase the strength of joints
The epiphyses, or ends, of a long bone primarily contain what type of bone tissue?
Compact bone
Spongy bone
Yellow bone marrow
Articular cartilage
Which section of the vertebral column is located in the upper back and serves as the attachment point for the ribs?
Cervical Vertebrae
Thoracic Vertebrae
Lumbar Vertebrae
Sacrum
Which pair of bones is located in the lower arm, between the elbow and the wrist?
Tibia and Fibula
Humerus and Femur

What is the key structural difference in the composition of a short bone versus a flat bone?
Short bones are entirely compact bone, while flat bones are entirely spongy bone.
Short bones are mostly spongy bone with a thin compact layer; flat bones are spongy bone encased by two plates of compact bone.
Short bones are two plates of compact bone; flat bones are mostly spongy bone with a thin compact layer.
Both bone types have identical compositions but differ in their overall shape.
