PE2 Flashcards
This muscle is located on the anterior surface of the body.
pectoralis major
Other options include latissimus dorsi, trapezius, and bicep femoris
Which muscle is located in the upper extremities?
Deltoid
Other options include fibularis longus, Gluteus Maximus, and Gastrocnemius
What accounts for the difference in the percent change in grip strength for the two time intervals?
Rapid use of HIP for muscle contraction and ATP replenishment leads to muscle fatigue
Understanding muscle contraction and energy depletion is crucial for explaining grip strength changes.

[pivot joint]
The thumb, specifically between the 1st metacarpal and a carpal, is an example of a _______.
[saddle joint]

Multiple Choice: Which ligament is located at the back of the knee? A) ACL B) PCL C) MCL
B) PCL
Where do the ACL and PCL cross each other?
In the center of the knee joint.
True or False: The patellar tendon is part of the quadriceps mechanism.
True
What is the location of the MCL?
It is located on the inner side of the knee joint.
Fill in the blank: The __________ helps to prevent excessive side-to-side motion of the knee.
MCL
Which ligament provides stability to the knee during lateral movements?
