Which structure of a long bone contains the yellow bone marrow and serves as a cavity for fat storage?
Epiphysis
Medullary canal
Periosteum
Articular cartilage
Which of the following bones is NOT part of the axial skeleton?
Parietal bone
Mandible
Femur
Sacrum
Which statement correctly differentiates between true ribs and floating ribs?
True ribs are attached directly to the sternum, while floating ribs are not attached to the sternum at all.
True ribs are only found in the cervical region, while floating ribs are in the thoracic region.
Floating ribs are attached to the sternum by cartilage, while true ribs are not attached.
Both true and floating ribs are attached to the xiphoid process.
Given a diagram of a long bone, how would you identify the periosteum and explain its function?
The periosteum is the inner lining of the medullary canal; it stores fat.
The periosteum is the outer fibrous covering of the bone; it provides nourishment and serves as an attachment point for tendons and ligaments.
The periosteum is the cartilage covering the epiphysis; it reduces friction at joints.
The periosteum is the spongy bone at the ends; it produces red blood cells.
Analyze the role of fontanels in the skulls of infants and explain why they are important for development.
Fontanels allow for the attachment of muscles to the skull.
Fontanels provide flexibility for the skull during birth and allow for brain growth after birth.
Fontanels are sites of ossification that strengthen the skull immediately after birth.
Fontanels are responsible for producing red blood cells in infants.
A patient has a fracture in the diaphysis of their femur. Based on your understanding of bone structure, what complications might arise if the periosteum is also damaged?
The bone will not be able to store fat.
The bone may have impaired healing and reduced ability to attach muscles and tendons.
The bone will lose its articular cartilage.
The bone will become part of the axial skeleton.
Compare and contrast the functions of the endosteum and articular cartilage in long bones.
Both provide structural support to the bone shaft.
The endosteum lines the medullary canal and is involved in bone growth and repair, while articular cartilage covers the epiphysis and reduces friction at joints.
Both are involved in the production of red blood cells.
The endosteum covers the outside of the bone, while articular cartilage lines the medullary canal.
A student is asked to classify the sacrum, maxilla, and sesamoid bones. Which of the following correctly matches each bone to its type?
Sacrum: Irregular, Maxilla: Flat, Sesamoid: Short
Sacrum: Irregular, Maxilla: Irregular, Sesamoid: Sesamoid
Sacrum: Flat, Maxilla: Long, Sesamoid: Irregular
Sacrum: Short, Maxilla: Flat, Sesamoid: Long
