61. |
ligament
|
strong band of dense connective tissue spanning between bones |
62. |
medial (internal) rotation
|
movement of the arm at the shoulder joint or the thigh at the hip joint that brings the anterior
surface of the limb toward the midline of the body |
63. |
medial excursion
|
side-to-side movement that returns the mandible to the midline |
64. |
medial meniscus
|
C-shaped fibrocartilage articular disc located at the knee, between the medial condyle of the femur
and medial condyle of the tibia |
65. |
medial tibiofemoral joint
|
portion of the knee consisting of the articulation between the medial condyle of the tibia and the
medial condyle of the femur; allows for flexion/extension at the knee |
66. |
meniscus
|
articular disc |
67. |
multiaxial joint
|
type of diarthrosis; a joint that allows for movements within three planes (three axes) |
68. |
opposition
|
thumb movement that brings the tip of the thumb in contact with the tip of a finger |
69. |
patellar ligament
|
ligament spanning from the patella to the anterior tibia; serves as the final attachment for the
quadriceps femoris muscle |
70. |
periodontal ligament
|
band of dense connective tissue that anchors the root of a tooth into the bony jaw socket |
71. |
pivot joint
|
synovial joint at which the rounded portion of a bone rotates within a ring formed by a ligament and
an articulating bone; functionally classified as uniaxial joint |
72. |
plane joint
|
synovial joint formed between the flattened articulating surfaces of adjacent bones; functionally
classified as a multiaxial joint |
73. |
plantar flexion
|
foot movement at the ankle in which the heel is lifted off of the ground |
74. |
posterior cruciate ligament
|
intracapsular ligament of the knee; extends from the posterior, superior surface of the tibia to the
inner aspect of the medial condyle of the femur; prevents anterior displacement of the femur when the
knee is flexed and weight bearing |
75. |
posterior talofibular ligament
|
intrinsic ligament located on the lateral side of the ankle joint, between the talus bone and lateral
malleolus of the fibula; supports the talus at the talocrural joint and resists excess inversion of the foot |
76. |
pronated position
|
forearm position in which the palm faces backward |
77. |
pronation
|
forearm motion that moves the palm of the hand from the palm forward to the palm backward position |
78. |
protraction
|
anterior motion of the scapula or mandible |
79. |
proximal radioulnar joint
|
articulation between head of radius and radial notch of ulna; uniaxial pivot joint that allows for
rotation of radius during pronation/supination of forearm |
80. |
pubofemoral ligament
|
intrinsic ligament spanning from the pubis of the hip bone to the femur, on the anterior-inferior
aspect of the hip joint |
81. |
radial collateral ligament
|
intrinsic ligament on the lateral side of the elbow joint; runs from the lateral epicondyle of humerus
to merge with the annular ligament |
82. |
reposition
|
movement of the thumb from opposition back to the anatomical position (next to index finger) |
83. |
retraction
|
posterior motion of the scapula or mandible |
84. |
rotation
|
movement of a bone around a central axis (atlantoaxial joint) or around its long axis (proximal
radioulnar joint; shoulder or hip joint); twisting of the vertebral column resulting from the summation
of small motions between adjacent vertebrae |
85. |
rotator cuff
|
strong connective tissue structure formed by the fusion of four rotator cuff muscle tendons to the
articular capsule of the shoulder joint; surrounds and supports superior, anterior, lateral, and
posterior sides of the humeral head |
86. |
saddle joint
|
synovial joint in which the articulating ends of both bones are convex and concave in shape, such as
at the first carpometacarpal joint at the base of the thumb; functionally classified as a biaxial joint |
87. |
subacromial bursa
|
bursa that protects the supraspinatus muscle tendon and superior end of the humerus from rubbing
against the acromion of the scapula |
88. |
subcutaneous bursa
|
bursa that prevents friction between skin and an underlying bone |
89. |
submuscular bursa
|
bursa that prevents friction between bone and a muscle or between adjacent muscles |
90. |
subscapular bursa
|
bursa that prevents rubbing of the subscapularis muscle tendon against the scapula |
