Osteokinematics & Arthrokinematics
This plane divides the body into right and left portions.
What is the sagittal plane?
The sternoclavicular joint is the only direct connection between the upper extremity and this structure.
What is the axial skeleton?
This carpal bone acts as the axis of rotation for wrist motion.
What is the capitate?
The primary function of the menisci.
What is shock absorption and increasing joint congruency?
Pronation consists of these three motions.
What are dorsiflexion, eversion, and abduction?
Movement occurring around the mediolateral axis includes these two motions.
What are flexion and extension?
The primary ligament limiting clavicular elevation at the SC joint.
What is the costoclavicular ligament?
The ligament forming the roof of the carpal tunnel.
What is the transverse carpal ligament?
This ligament limits excessive valgus stress.
What is the medial collateral ligament?
The ligament that limits excessive eversion.
What is the deltoid ligament?
This type of kinematic chain occurs when the distal segment is fixed.
What is a closed kinematic chain?
Retraction at the SC joint is associated with this common exercise.
What is rowing?
The TFCC primarily stabilizes this joint.
What is the distal radioulnar joint?
During stair descent, the quadriceps are primarily contracting in this manner.
What is eccentric contraction?
The ligament that limits excessive inversion.
What is the calcaneofibular ligament?
During shoulder abduction, the humeral head rolls superiorly and slides inferiorly because of this rule.
What is the convex-concave rule?
The SC joint is classified as this type of synovial joint.
What is a saddle joint?
The optimal wrist position for maximum grip strength.
What is slight wrist extension with ulnar deviation?
A complete lesion of this nerve causes paralysis of all knee extensors.
What is the femoral nerve?
This joint allows the foot to adapt to uneven terrain through pronation and supination.
What is the subtalar joint?
Name the three fundamental arthrokinematic motions.
What are roll, slide, and spin?
Name the three osteokinematic motions available at the SC joint.
What are elevation/depression, protraction/retraction, and clavicular rotation?
Which carpal bone is considered the most unstable?
What is the lunate?
Patellofemoral compression forces are highest during activities involving this range of knee flexion.
What is 60-90 degrees of knee flexion?
The largest tarsal bone and attachment site of the Achilles tendon.
What is the calcaneus?
