Joint Resistance – Biology Exam
The key terms of Biology Exam include, Effort, Joint, Resistance, Fulcrum, Synovial, Pivot, Arm.
In the body, a joint serves as a ________ for a long bone.
fulcrum – correct
lever
effort arm
resistor
When considering leverage, the part of the bone from the muscle attachment to the joint would be the
fulcrum.
effort arm. – correct
resistance arm.
If a heavy load is at one end of a lever, the distance between the fulcrum and that load is called the
effort arm.
resistance arm. – correct
lever length.
In a first-class lever
the fulcrum is in the middle, between the effort and the resistance. – correct
the resistance is between the fulcrum and the effort.
the effort is between the resistance and the fulcrum.
there is no effort arm.
Fluid-filled sacs that cushion synovial joints are called
fat pads.

bursae. – correct
menisci.
diarthroses.
Synovial fluid is
a watery fluid produced by hyaline cartilage.
an oily fluid produced by the synovial membrane. – correct
a watery fluid produced by capsular ligaments.
