6. What is the main
function of ligaments in the skeletal system?
Answer: Stability
7. What is the name for
the needle-like pieces of bone found in spongy bone tissue?
Answer: Trabeculae
8. What is the primary
function of the skeletal system?
Answer: The primary function of the skeletal
system is to provide structural support, protect internal organs, facilitate
movement, store minerals, and produce blood cells.
9. How does the
evolutionary history of the skeletal system contribute to its adaptability?
Answer: The evolutionary history of the
skeletal system has led to its remarkable adaptability, as it has evolved over
millions of years to meet the changing needs of different species and adapt to
various environments and modes of life.
10. Which component primarily contributes to the
flexibility and resilience of bones?
A) Trabeculae
B) Collagen fibers
C) Calcium phosphate
D) Lacunae
Answer: B) Collagen fibers
11. What is the
function of canaliculi in bone tissue?
A) Housing osteocytes
B) Facilitating nutrient and waste exchange
C) Forming the dense outer layer of bones
D) Initiating bone development
Answer: B) Facilitating nutrient and waste
exchange
12. Which component of the skeletal system acts as
a cushion between bones, reducing friction and absorbing shock during movement?
A) Bones
B) Joints
C) Cartilage
D) Ligaments
Answer: C) Cartilage
13. What is the primary
function of ligaments in the skeletal system?
A) Providing support and protection to
internal organs
B) Allowing for movement at joints
C) Absorbing shock during movement
D) Connecting bones to each other, providing
stability
Answer: D) Connecting bones to each other,
providing stability
14. Which type of joint
allows for the most extensive range of movement?

15. The axial skeleton
consists of the skull, vertebral column, rib cage, and ________.
Answer: sternum
16. The ________
encases and protects the brain while providing attachment points for facial
muscles.
Answer:
skull
17. The rib cage,
composed of ribs and the ________, surrounds and protects vital organs such as
the heart and lungs.
Answer: sternum
18. What bones comprise
the shoulder girdle in the appendicular skeleton?
Answer: The shoulder girdle consists of the
clavicle and scapula.
19. Which bones are
included in the lower limb of the appendicular skeleton?
Answer: The lower limb of the appendicular
skeleton includes the pelvic girdle (hip bones), thigh bone (femur), leg bones
(tibia and fibula), and bones of the foot (tarsals, metatarsals, and
phalanges).
20. What is the role of
the appendicular skeleton in movement and locomotion?
Answer: The appendicular skeleton facilitates
movement and locomotion by providing the structural framework for the upper and
lower limbs, enabling actions such as reaching, grasping, walking, running, and
jumping.
