- True/False: Both first- and second-class levers operate at a mechanical disadvantage. False
- First-class levers. a) are typified by tweezers or forceps b) in the body can operate at a mechanical advantage or mechanical disadvantage, depending on specific lo- cation c) are the type found in the joints forming the ball of the foot as used in raising the body on the toes d) have load at one end of the lever, fulcrum at the other, and effort applied somewhere in the middle b) in the body can operate at a mechanical advantage or mechanical disadvan- tage, depending on specif- ic location
- True/False: Regardless of type, all levers follow the same basic principle: effort farther than load from ful- crum = mechanical advantage; effort nearer than load to fulcrum = mechanical disadvantage. true

- All the tendons of the rotator cuff muscles combine at which location? the humeral head
- To keep the humeral head centered within the glenoidal cavity the rotator cuff muscles must be . located in the same plane
- The location of the rotator cuff muscles in relation to the glenohumoral joint minimizes the upward pres- sure against the. acromion of the scapula
