What type of muscle is the vastus lateralis?
The vastus lateralis muscle, a portion of the quadriceps femoris muscle group, has been the muscle of choice for biopsies because of its mixed fiber type composition, trainability, and accessibility.
Where is the vastus lateralis muscle located?
The vastus lateralis muscle is located on the lateral side of the thigh. This muscle is the largest of the quadriceps which includes: rectus femoris, vastus intermedius, and vastus medialis.
What is vastus lateralis?
The vastus lateralis (VL) is a unipennate muscle and a member of the anterior compartment of the thigh along with the sartorius, quadriceps femoris, rectus femoris (RF), vastus medialis (VM), and vastus intermedius (VI) muscles.
Is the vastus lateralis a Bipennate muscle?
These muscles can be differentiated by the orientation of the muscle fibers. The rectus femoris is a bipennate muscle with fibers of the lateral half of the muscle running superomedial to inferolateral, whereas the vastus lateralis is a unipennate muscle with fibers running superolateral to inferomedial (Fig. 78.4).
Is the vastus lateralis muscle deep or superficial?
The muscles are located: superficial: rectus femoris. medial: vastus medialis. lateral: vastus lateralis.
Which muscle is located on the posterior area of the body?
The posterior muscles include the trapezius, rhomboid major, and rhomboid minor. When the rhomboids are contracted, your scapula moves medially, which can pull the shoulder and upper limb posteriorly.
What is the line of pull of the vastus lateralis on the patella?
The measurement of lateral line of pull of the quadriceps relative to the patella is referred to as Q-angle. The Q-angle is formed by 2 lines. One line connecting from the anterior superior iliac spine to the middle of the patella and the other connecting from the middle of the patella to the tibial tuberosity.
Why is it called vastus lateralis?
Vastus Lateralis Each of the muscles are also named for that exact location. The vastus lateralis is located on the lateral side, meaning if you were to draw an imaginary line down the middle of the body, this muscle sits furthest away from that line.
Is the vastus lateralis Biarticular?
Which of them is a biarticular muscle and what are its actios? Rectus femoris, vastus lateralis, vastus intermedius, vastus medialis. Rectus femoris is the biarticular part.
What are the Bipennate muscle?
A type of pennate muscle wherein the muscle fibers or fascicles are in opposite sides of the central tendon. Example of bipennate muscle is rectus femoris.
Is the vastus medialis Unipennate?
The vastus lateralis (VL) is a unipennate muscle and a member of the anterior compartment of the thigh along with the sartorius, quadriceps femoris, rectus femoris (RF), vastus medialis (VM), and vastus intermedius (VI) muscles.
What is the VLO muscle?
Bone Joint Surg. 694.545549, 1987) have described the vastus lateralis obliquus (VLO). These muscles are the terminal medial and lateral insertions of the vastus medialis and vastus lateralis.
