SECTION 1: SKELETAL SYSTEM
QUESTION 1
Osteoporosis is best defined as:
A) An increase in bone density
B) A bone disease in which bones become impaired, porous, and thinner
C) A condition where bones become denser and heavier
D) An autoimmune disease affecting joints
ANSWER: B
RATIONALE: Osteoporosis is characterized by decreased bone density and quality,
leading to porous, thinner bones that are more susceptible to fractures.
QUESTION 2
Children's bones are _______ than adults.
A) More brittle
B) Softer
C) Denser
D) Longer
ANSWER: B
RATIONALE: Children's bones contain more collagen and are more flexible (softer)
compared to adult bones, which are more mineralized and rigid.
QUESTION 3
The axial skeleton consists of what?
A) Arms, legs, and pelvis
B) Cranium, sternum, ribs, and coccyx
C) Scapula, clavicle, and humerus
D) Femur, tibia, and fibula
ANSWER: B
RATIONALE: The axial skeleton includes the bones of the head and trunk, specifically the
cranium, sternum, ribs, vertebral column, and coccyx.
QUESTION 4
What is a function of the skeletal system related to red and white blood cells?
A) Storage of calcium
B) Production of blood cells (hematopoiesis)
,C) Protection of internal organs
D) Support of body structure
ANSWER: B
RATIONALE: The bone marrow within bones is responsible for the production of red
blood cells (erythropoiesis) and white blood cells.
QUESTION 5
The three body types (somatotypes) are:
A) Ectomorph, Mesomorph, Endomorph
B) Somatotype A, B, and C
C) Endomorph, Ectomorph, and Mixed
D) Thin, Athletic, and Heavy
ANSWER: A
RATIONALE: The three somatotypes are:
● Ectomorph: Long and lean, with little body fat or muscle
● Mesomorph: Athletic build, more muscle than body fat
● Endomorph: Curvy, greater body fat than muscle
QUESTION 6
Epiphysis refers to:
A) The shaft of a long bone
B) The end of a long bone
C) The growth plate
D) The hollow center of a bone
ANSWER: B
RATIONALE: The epiphysis is the rounded end of a long bone, which is typically covered
in articular cartilage.
QUESTION 7
What type of bone is the pelvic bone?
A) Long bone
B) Short bone
C) Flat bone
D) Irregular bone
, ANSWER: C
RATIONALE: The pelvic bone (ilium, ischium, pubis) is classified as a flat bone, which
provides broad surfaces for muscle attachment and protection.
QUESTION 8
Carpals and tarsals are what type of bone?
A) Long bones
B) Short bones
C) Flat bones
D) Irregular bones
ANSWER: B
RATIONALE: Carpal bones (wrist) and tarsal bones (ankle) are classified as short bones,
which are roughly cube-shaped and provide stability and shock absorption.
QUESTION 9
What would you find in the medullary cavity of a long bone?
A) Articular cartilage
B) Bone marrow
C) Periosteum
D) Hyaline cartilage
ANSWER: B
RATIONALE: The medullary cavity (the central hollow area) of a long bone contains bone
marrow, which is responsible for blood cell production.
QUESTION 10
How many joints are there in the human body?
A) 206
B) 320 (ish)
C) 450
D) 600
ANSWER: B
RATIONALE: The human body has approximately 320 joints, though some sources may
cite slightly different numbers.
