KU BIOL 240 Exam 2 (2026) | Fundamentals of Human
Anatomy | Practice Questions & Verified Answers
1. Describe the role of joints in the skeletal system.
Joints connect bones and allow for movement and flexibility in
the skeletal system.
Joints are rigid structures that provide support to the body.
Joints serve only as points of attachment for muscles.
Joints are responsible for producing blood cells in the body.
2. Describe why irregular bones are classified as the most complex type of
bone structure.
Irregular bones have varied shapes and complex structures
that do not fit into other categories, allowing for multiple
functions.
Irregular bones are the longest bones in the body, providing
support and leverage.
Irregular bones are small and provide stability to joints.
Irregular bones are flat and serve primarily as protective
structures.
3. Describe the role of articular cartilage in the functioning of synovial
joints.
Articular cartilage provides a smooth surface for joint
movement and absorbs shock.
Articular cartilage produces synovial fluid.
Articular cartilage forms the structure of the joint capsule.
Articular cartilage connects muscles to bones.
,4. If articular cartilage in a synovial joint is damaged, what impact would
this have on joint function?
Improved flexibility and range of motion
No impact on joint function
Enhanced shock absorption
Increased friction and pain during movement
5. What is the function of phosphorus?
Bone mineralization
Acid-base balance
Component of DNA and RNA
All of the above
6. In a scenario where a person has a condition that affects the stability of
their skull sutures, which type of joint is primarily impacted?
Cartilaginous joints
Amphiarthroses joints
Synarthroses joints
Diarthroses joints
7. What is the total number of facial bones in the human skeleton?
14
16
10
12
,8. Describe how the synovial membrane contributes to the overall function
of synovial joints.
The synovial membrane absorbs shock and prevents injury to the
joint.
The synovial membrane produces synovial fluid, which
lubricates the joint and reduces friction during movement.
The synovial membrane serves as a barrier to protect the joint
from infection.
The synovial membrane connects bones and provides stability to
the joint.
9. When does ossification end?
When one is at around age 40
When one becomes a teenager
When one becomes a mature adult
It doesn't end and it continues throughout life
10. Describe the significance of intramembranous ossification in the
development of the skeletal system.
Intramembranous ossification is primarily responsible for the
growth of long bones.
Intramembranous ossification is crucial for forming flat bones,
such as those in the skull.
Intramembranous ossification occurs only in adults.
Intramembranous ossification is the process of bone repair after
a fracture.
, 11. If a person experiences a fracture in a flat bone, such as the sternum,
what implications might this have for the surrounding organs?
A fracture in a flat bone like the sternum would mainly affect the
spinal column.
A fracture in a flat bone like the sternum could lead to
potential damage to the heart and lungs due to their proximity.
A fracture in a flat bone like the sternum would primarily affect
the arm and shoulder mobility.
A fracture in a flat bone like the sternum would have no
significant impact on surrounding organs.
12. If the fibrous layer of a synovial joint is damaged, what potential issue
could arise?
Decreased production of synovial fluid.
Increased joint instability.
Improved bone density in the joint area.
Enhanced flexibility of the joint.
13. If a patient has a fracture in an irregular bone, such as the vertebrae,
what implications might this have for their overall skeletal health?
It would primarily affect the growth of long bones.
It could affect spinal stability and nerve function.
It would have no significant impact on overall health.
It would only impact muscle strength.
14. What type of movement is characterized by rotation around a single
axis in synovial joints?
Biaxial movement
