Biomechanics of Resistance Exercise Flashcards
the mechanisms through which the muscles and skeleton work together to create movement
biomechanics
the skull (cranium), vertebral column (vertebrae C1 through the coccyx), ribs, and sternum
axial skeleton
the shoulder (or pectoral) girdle (left and right scapula and clavicle), bones of the arms, wrists, and hands (left and right humerous, 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, tibia, fibula, tarsals, metatarsals, and phalanges)
appendicular skeleton
junctions of bones
joints
joints that allow no movement or virtually no movement
fibrous joints (sutures of the skull)
joints that allow limited movement
cartilaginous joints (ex vertebral disks)
joints that allow considerable movement as in sports and exercise movements
synovial joints (ex: elbows & knees)
the smooth covering on the articulating ends of bones
hyaline cartilage
the fluid/gel contained in the joint capsule
synovial fluid
joints which allow bones to rotate around 1 axis
uniaxial joint (ex: elbow, knee)
joints that allow moevement around 2 perpendicular axes
biaxial joint
joints that allow movement about all three axes
multiaxial joint
the series of vertebral bones separated by flexible disks that allow movement to occur
vertebral column
vertebrae found in the neck
7 cervical vertebrae
vertebrae of the middle and upper back
12 thoracic vertebrae
