Skeletal system

What movements occurs in the sagittal plane?

What movements do not occur in the frontal plane?

Which is the transverse plane?

The ligament is a tough band of slightly [blank_start]elastic connective tissue[blank_end] which connects [blank_start]bone to bone[blank_end] and stabilises joints during movement. Synovial fluid is a [blank_start]lubricating[blank_end] liquid contained within the [blank_start]joint cavity[blank_end] which reduces friction and nourishes articular cartilage. The articular cartilage is a smooth tissue which covers the surface of the [blank_start]articulating bones[blank_end] which absorbs shock and allows friction-free movement. The joint capsule is a [blank_start]fibrous sac[blank_end] with an inner synovial membrane which encloses and [blank_start]strengthens[blank_end] the joint secreting synovial fluid. The bursa is a closed, fluid-filled sac found where tendons rub over bones. It reduces friction between [blank_start]tendons and bones.[blank_end]

Which joints are hinge joints?

Abduction - the movement of [blank_start]limbs away from the midline of the body.[blank_end] Adduction - the movement of [blank_start]limbs towards the midline of the body.[blank_end] Horizontal flexion - the movement of the limbs [blank_start]away from the[blank_end] midline of the body parallel to the ground. Horizontal extension - the movement of the limbs [blank_start]towards the[blank_end] midline of the body parallel to the ground. Plantar flexion - movement [blank_start]at the ankle joint as the toes move down[blank_end]. Doris-Flexion - movement [blank_start]at the ankle joint as the toes move up[blank_end].
