HKR 1001 Exam Questions Answered Correctly Latest Update 2025-2026
musculoskeletal system - Answers The system of bones, joints, and skeletal muscles that support and
protect the body and permit movement
axial skeleton - Answers the part of the skeleton that includes the skull and spinal column and sternum
and ribs
appendicular skeleton - Answers Bones of the limbs and limb girdles that are attached to the axial
skeleton. Includes the shoulder (or pectoral) girdle (left and right scapula and clavicle); bones of the
arms, wrists,
and hands (left and right humerus, radius, ulna, carpals,
metacarpals, and phalanges); the pelvic girdle (left and
right coxal or innominate bones); and the bones of the
legs, ankles, and feet (left and right femur, patella, tibia,
fibula, tarsals, metatarsals, and phalanges).
joints - Answers Articulations between adjoining bones. Can be categorized by the number of directions
about which rotation can occur.
fibrous joints - Answers Consists of inflexible layers of dense connective tissue, holds the bones tightly
together. Generally immovable. Ex: sutures of the skull.
cartilaginous joints - Answers Allow only slight movement and consist of bones connected entirely by
cartilage. Ex: invertebral disks.
synovial joints - Answers Created where two bones articulate to permit a variety of motions. Sport and
exercise movements occur mainly about these joints, whose most important features are low friction
and a large range of motion. Ex: elbows and knees
hyaline cartilage - Answers Most common type of cartilage; it is found on the ends of long bones, ribs,
and nose. Covers articulating bone ends.
synovial fluid - Answers The small amount of liquid within a joint used as lubrication.
uniaxial joint - Answers Bones are free to move in one plane, around one axis (one direction), ex: Hinge
joint - flexion/extension, Pivot joint. Knees and elbows.
biaxial joint - Answers Bones are free to move in two planes around two perpendicular axes (two
directions), ex: Condyloid and Saddle - flexion/extension & abduction/adduction. Wrist and ankles.
multiaxial joint - Answers Ball and socket hip joint and shoulders, three degrees of freedom or axes of
rotation.
