Show Answers:

  1. Abduction
    Movement away from the midline of the body
  2. Adduction
    Movement toward the midline off the body
  3. Articular cartilage
    Hyaline cartilage attached to articular bone surfaces
  4. Articulation
    The action or manner in which the parts come together at a joint
  5. Ball-and-socket joint
    An articulation (as the hip joint) in which the rounded head of one bone fits into a cuplike cavity of the other and admits movement in any direction
  6. Cartilage
    A usually translucent somewhat elastic tissue that composes most of the skeleton of vertebrate embryos and except for a small number of structures (as some joints, respiratory passages, and the external ear) is replaced by bone during ossification in the higher vertebrates.
  7. Circumduction
    A movement at a synovial joint in which the distal end of the bone moves in a circle while the proximal end remains relatively stable
  8. Dorsiflexion
    Bending the foot in the direction of the dorsum (upper surface)
  9. Extension
    An unbending movement around a joint in a limb (as the knee or elbow) that increases the angle between the bones of the limb at the joint
  10. Flexion
    A bending movement around a joint in a limb (as the knee or elbow) that decreases the angle between the bones of the limb at the joint
  11. Goniometer
    An instrument for measuring angles (as of a joint or the skull)
  12. Hinge joint
    Joint between bones (as at the elbow or knee) that permits motion in only one plane
  13. Hyaline cartilage
    Translucent bluish white cartilage consisting of cells embedded in an apparently homogeneous matrix, present in joints and respiratory passages, and forming most of the fetal skeleton
  14. Joint
    The point of contact between elements of an animal skeleton whether movable or rigidly fixed together with the surrounding and supporting parts (as membranes, tendons, or ligaments)
  15. Ligament
    Dense regular connective tissue that attaches bone to bone
  16. Plantar flexion
    Bending the foot in the direction of the plantar surface (sole)
  17. Rotation
    Moving a bone around its own axis, with no other movement
  18. Synovial cavity
    The space between the articulating bones of a synovial joint, filled with synovial fluid. Also called a joint cavity.
  19. Synovial fluid
    Secretion of synovial membranes that lubricates joints and nourishes articular cartilage
  20. Synovial joint
    A fully moveable joint in which the synovial (joint) cavity is present between the two articulating bones
  21. Tendon
    A white fibrous cord of dense regular connective tissue that attaches muscle to bone
  22. Actin
    A contractile protein that is part of the thin filaments in muscle fibers
  23. Carpal tunnel syndrome
    A condition caused by compression of the median nerve in the carpal tunnel and characterized especially by weakness, pain, and disturbances of sensation in the hand and fingers
  24. Endomysium
    The delicate connective tissue surrounding the individual muscular fibers within the smallest bundles
  25. Epimysium
    The external connective-tissue sheath of a muscle
  26. Fascicle
    A small bundle or cluster, especially of nerve or muscle fibers
  27. Insertion
    The attachment of a muscle tendon to a moveable bone or the end opposite the origin
  28. Myosin
    The contractile protein that makes up the thick filaments of muscle fibers
  29. Origin
    The attachment of a muscle tendon to a stationary bone or the end opposite the insertion
  30. Perimysium
    The connective-tissue sheath that surrounds a muscle and forms sheaths for the bundles of muscle fibers
  31. Sarcomere
    Any of the repeating structural units of striated muscle fibrils
  32. Sliding filament mechanism
    The explanation of how thick and thin filaments slide relative to one another during striated muscle contraction to decrease sarcomere length
  33. Tropomyosin
    A protein of muscle that forms a complex with troponin regulating the interaction of actin and myosin in muscular contraction
  34. Troponin
    A protein of muscle that together with tropomyosin forms a regulatory protein complex controlling the interaction of actin and myosin and that when combined with calcium ions permits muscular contraction
