Articulations and Body Movements

Martini Chapter 9

137

Knee

• Largest and most complex joint of the body• Allows flexion, extension, and some rotation• Three joints in one surrounded by a single joint

cavity• Femur-patellar• Lateral and medial tibia-femur joints

138

Knee Ligaments and Tendons

• Tendon of the quadriceps femoris muscle

• Fibular and tibial collateral ligaments

• Patellar ligament

139

Knee

• Anterior cruciate ligament

• Posterior cruciate ligament

• Medial meniscus

• Lateral meniscus

140

MovementsFlexion: joint angle is decreased Extension: joint angle is increased

141

Flexion/Extension/Hyperextension

142

Adduction/Abduction

• Adduction: Moving limb toward the body midline

• Abduction: moving limb away from body midline

• Circumduction: flexion-extension-adduction-abduction

143

Rotation

• The turning of a bone around its own long axis

144

Supination/Pronation

145

Eversion/Inversion

146

Dorsiflexion/Plantar Flexion
