PTS Canfitpro theory exam 2 Questions with
Detailed Verified Answers
Functions of the skeletal system Ans: support, movement, protection,
mineral deposit, blood cell formation, energy reservoir
the average human adult skeleton has ....bones Ans: 206 bones
bones are .....fluid and......solid Ans: 50%, 50%
......make bones rigid and.....makes them strong Ans: minerals, protein
long bones Ans: femur, humerus serve as levers for movement
short bones Ans: tarsals (ankle), carpals (wrist) give strength to joints
but with limited mobility
flat bones Ans: ribs, scapulae provide a broad site for muscle
attachment and protect the internal organs.
irregular bones Ans: ischium, pubis, vertebrae protect internal organs
and support the body
axial skeleton Ans: 80 bones - skull 29, vertebral column 26, thorax 25
appendicular skeleton Ans: 126 bones - pectoral girdle 4 bones, upper
limbs 60 bones, pelvic girdle 2 bones, lower limbs 60 bones
how many joint types are there? Ans: fibrous, cartilaginous, synovial.
, Page | 2
fibrous connective tissue that support the articulation between bones at
joints Ans: ligaments, joint capsules
where can we find fibrous joints? Ans: the bones of the skull and pelvis
are held together by fibrous joints. the radius and ulna are also held in
relation to one another through fibrous tissue. they allow very little if any
movement
where can we find cartilaginous joints? Ans: between the ribs and
sternum and between the vertebrae. allow little to no movement
how many types of synovial joints are there? Ans: 6 types: gliding
(carpals and tarsals)
pivot (radius and ulna),
hinge - allow movement in one direction or plane of motion- (elbow and
knee)
condyloid - allow movement in 2 directions or planes of motion
(knuckles).
saddle (thumb)
ball and socket - allow movement in three directions and planes of
motion (shoulders and hips that allow circumduction).
anterior and posterior Ans: front and back of the body
medial and lateral Ans: closer to the midline, further from the midline
superior and inferior Ans: body part thats above another and below
another
supine and prone Ans: face up, face down
dorsal , plantar Ans: top of foot, bottom of foot
, Page | 3
dorsal , plantar Ans: top of foot, bottom of foot
shoulder girdle movements Ans: elevation-depression
abduction-adduction
upward rotation-downward rotation
shoulder joint movements Ans: flexion-extension
abduction-adduction
medial rotation-lateral rotation
horizontal abduction - adduction
circumduction
elbow joint movements Ans: flexion-extension
radioulnar joint movements Ans: pronation - supination
wrist joint movements Ans: flexion-extension
radial flexion - ulnar flexion
vertebral column spine movements Ans: flexion extension
lateral flexion
rotation
lumbosacral joint movements Ans: flexion -extension (apt-ppt)
hip joint movements Ans: flexion-extension
abduction-adduction
