Questions and Answers
1. How many bones are in the human body?
a) 206
b) 208
c) 210
d) 212
Answer a) 206
Explanation: The adult human body typically has 206 bones, which form the adult skeleta
system.
2. The ribcage is part of which skeleton?
a) Appendicular skeleton
b) Axial skeleton
c) Cranial skeleton
d) Pelvic skeleton
Answer b) Axial skeleton
Explanation: The ribcage, along with the skull and vertebral column, is part of the axial
skeleton, which supports the central axis of the body.
3. How many vertebrae within the vertebral (spinal) column can move independently?
a) 12
b) 24
c) 33
d) 7
Answer b) 24
Explanation: There are 24 movable vertebrae in the cervical, thoracic, and lumbar regions
,of the spine; the remaining bones (sacrum and coccyx) are fused.
4. Movement between two adjacent vertebrae is made possible by what?
a) Intervertebral discs
b) Facet joints
c) Ligaments
d) Spinous processes
Answer b) Facet joints
Explanation: The facet joints are synovial joints that allow movement between adjacent
vertebrae.
5. Wolff's Law describes what?
a) The way bones can grow or shrink
b) The process of muscle hypertrophy
c) The repair of cartilage
d) The blood supply to bones
Answer a) The way bones can grow or shrink
Explanation: Wolff's Law states that bone adapts to the loads under which it is placed,
growing stronger with stress and shrinking with disuse.
6. New bone material is formed by what?
a) Osteoclasts
b) Osteoblasts
c) Chondrocytes
d) Fibroblasts
Answer b) Osteoblasts
Explanation: Osteoblasts are cells responsible for new bone formation.
7. The strong connective tissue on the bottom of each foot is the
a) Achilles tendon
,b) Plantar fascia
c) Plantar aponeurosis
d) Calcaneal ligament
Answer c) Plantar aponeurosis
Explanation: The plantar aponeurosis (or fascia) supports the arch of the foot and is a thic
connective tissue on the bottom of the foot.
8. During the lowering phase of a biceps curl, the elbow flexors are performing which
type of muscle action?
a) Concentric
b) Eccentric
c) Isometric
d) Isokinetic
Answer b) Eccentric
Explanation: Eccentric muscle action occurs when the muscle lengthens under tension, as
during the controlled lowering of a weight.
9. According to Thomas Myers, how many categories of fascial lines are in the human
body?
a) 5
b) 6
c) 7
d) 8
Answer c) 7
Explanation: Thomas Myers describes 7 fascial lines in the body, which are interconnecte
chains of connective tissue.
10. What are two types of sensory feedback that fascia can provide?
a) Proprioception and pain
b) Temperature and pressure
, c) Touch and vibration
d) Balance and equilibrium
Answer a) Proprioception and pain
Explanation: Fascia contains sensory receptors that provide proprioception (body position
awareness) and can also transmit pain signals.
11. Which of the following is not a function of skeletal muscle?
a) Movement of bones and joints
b) Posture maintenance
c) Blood cell production
d) Heat production
Answer c) Blood cell production
Explanation: Blood cell production occurs in the bone marrow, not directly through skelet
muscle.
12. An eccentric muscle action occurs when
a) The muscle shortens under tension
b) The pulling force of a muscle exceeds resistance
c) The pulling force of a muscle is less than the resistance force
d) The muscle remains at a fixed length
Answer c) The pulling force of a muscle is less than the resistance force
Explanation: Eccentric action involves muscle lengthening as it resists an external force,
such as lowering a weight.
13. The primary roles of skeletal muscle are to
a) Develop tension and move joints
b) Store calcium
c) Produce hormones
d) Regulate blood flow
