Describe the functions of the patella? - correct answer ✔✔-quadricep muscles use the patella
as a fulcrum to increase power when extending the knee
-protects knee join
-maintains the position of the tendon during knee flexion
how is the patella different from other bones of the leg? - correct answer ✔✔it is a flat
seasamoid bone (covers tendons and aids in motion)
-used for protection rather than support
Name the bones of the pectoral girdle and pelvic girdle? - correct answer ✔✔pectoral: clavicle,
scapula, coracoid
pelvic: ischium, ilium pubis, coccyx
compare the pectoral and pelvic girdles with regard to strength, function and versatility? -
correct answer ✔✔pectoral muscle: less strength, more mobile and versatile
pelvic muscle: built for weight bearing, more stable, less versatile
what functions does the clavicle serve in the skeletal system? - correct answer ✔✔- support
upper arm and scapula
- improves leverage and strength in arm
- protects blood vessels an nerves that travel into the arm
,-shock absorber of upper torso
- attachment point for at least 6 muscles and tendons
to which bones does the scapula articulate? - correct answer ✔✔clavicle and humerus
describe the bone arrangements which are involved in the elbow joint? - correct answer
✔✔humeroulnar joint: hing joint, allows for only flexion and extension movements
humeroradial joint: ball-and-socket joint
superior radioulnar joint: any position of flexion and extension. radius can be rotated.
- movements include pronation and supination
describe the differences between a male pelvis and a female pelvis? - correct answer
✔✔female: larger, broader, oval opening
male: taller, narrower, more compact, heart-shaped opening
compare the elbow and the knee joint in terms of structure and function? - correct answer
✔✔elbow: uniaxial (hinge and pivot), cartilage and synovial membrane
knee: uniaxial (hinge), largest joint,
very stable from ligaments and tendons,
- meniscus cartilage (shock absorber)
-articulate cartilage (ends of femur and tibia)
, describe the four major curvatures of the vertebral column? - correct answer ✔✔Neck (cervical
concave)
chest (thoracic convex)
abdomen (lumbar concave)
lower back (convex coccygeal)
define lordosis? - correct answer ✔✔exaggerated lumbar curvature
(butt sticks out)
define kyphosis? - correct answer ✔✔exaggerated thoracic curve
(hump back)
define scoliosis? - correct answer ✔✔abnormal lateral curve
what is the function of the thoracic cage? - correct answer ✔✔-to protect heart, lungs,
abdominal organs
-protects shoulder girdle and arms
-attachment point of respiratory muscles
distinguish between true, false and floating ribs? - correct answer ✔✔true ribs: attach directly
to sternum
false ribs: attach to the rib above it, NOT sternum
floating ribs: attach to vertebrae only
