Weakness or instability of this muscle often results in winging of the scapula
What is the Serratus Anterior
100
The superior fibers of this muscle originate from the spinous processes of C1-C7, and also can be very dominant in pulling movements
What is the upper trapezius [ACTION](3)
100
This phasic muscle is a powerful extensor of the hip. The lower fibers adduct & externally rotate the leg, while the upper fibers abduct the leg
What is the gluteus maximus [ANTAGONIST](8)
100
This muscle works synergistically with the superior fibers of the glute max and glute medius to abduct the hip
What is the tensor fascia latae (TFL) [TURNS INTO WHAT](10)
200
Inferior fibers of this muscle are responsible for depression of the scapula
What is the lower trapezius
200
This muscle can cause anterior tilting of the scapula when in a shortened position
What is the pec minor [ORIGIN/INS](4)
200
This muscle runs down in two parallel parts, separated by a midline band of connective tissue called the linea alba
What is the rectus abdominis [ACTION](9)
200
This muscle inserts into the patellar tendon. It also extends the knee AND flexes the hip
What is the rectus femoris [ANTAGONIST](11)
300
This thick triangular muscle is 1 of 4 rotator cuff muscles, and inserts into the middle facet of the greater tubercle of the humerus
What is the infraspinatus [ACTION](1)
300
This rotator cuff muscle inserts on the lesser tubercle of the humerus
What is the subscapularis [ACTION](5)
300
This tear drop shaped muscle is often associated with presence of patellofemoral pain syndrome. It also extends the knee
What is the vastus medialis
300
This muscle bridges the sacrum and the femur, while sitting VERY close to the sciatic nerve
What is piriformis [ACTION](12)
400
This muscle can be divided by its MAJOR/MINOR components, and is responsible for retracting the scapula
What are the rhomboids
400
This muscle bridges the cervical spine and the scapula, and is innervated by C3, C4, C5 nerve root
What is levator scapula [ACTION](6)
400
This muscle runs along the shin bone and is responsible for dorsiflexing & inverting the foot
What is the tibialis anterior
400
This muscle bridges the lumbar spine and femur and also has a profound effect on tilting the pelvis anteriorly
What is the psoas [ANTAGONIST & ACTION](13)
500
This muscle inserts into the inferior facet of the greater tubercle of the humerus, and helps stabilize the shoulder joint
What is the teres minor [ACTION](2)
500
This muscle can act as an accessory respiratory muscle, and consist of a posterior, middle, and anterior portion
What are the scalenes [ORIGIN/INS](7)
500
These muscles run along the lateral compartment of the leg, turning into a tendon that wraps around the lateral malleolus and sharing the same insertion as the tibialis anterior
What are the peroneals
500
This muscle can cause a functional leg length descrepancy when one side is shortened, and sits right in front of the kidneys
