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.
