Where is rectus femoris located and function?
A muscle in the quadriceps, the rectus femoris muscle is attached to the hip and helps to extend or raise the knee . This muscle is also used to flex the thigh.
What are the proximal and distal attachments for the rectus femoris muscle?
The distal (furthest from the centre of the body) attachment of the rectus femoris is shared with the three vasti muscles at the tibial tuberosity, located on the anterio-proximal tibia (front, upper shin bone) . This common attachment is why these 4 muscles are grouped together as the quadricep femoris.
What are the two places the rectus femoris attaches?

Is the rectus femoris part of the hamstring?
The rectus femoris is part of the muscle group called the quadriceps in the upper thighs. Specifically, it is located on the anterior portion of the thigh muscle (in the very front).
Is rectus femoris a hip flexor?
The rectus femoris is the only quadriceps muscle that traverses both the hip and the knee joint. The rectus femoris is a powerful hip flexor , but it is largely dependent on the position of the knee and hip to assert its influence.
Where does the rectus femoris start?
The rectus femoris arises from two tendons that originate from the anterior inferior iliac spine and the other from the ridge of the acetabulum. The rectus femoris tendons conjoin at an acute angle spreading into the aponeurosis.
Which of the following muscles have a proximal attachment on the ilium?
Gluteus maximus – The gluteus maximus is the largest and most superficial muscle in the gluteal group (of three). The muscle attaches proximally along the inner and upper ilium at the crest (iliac crest or iliac spine).
How do you remember rectus femoris?
Where is rectus femoris muscle located?
The rectus femoris is a long, fleshy muscle located in the anterior compartment of the thigh . The rectus femoris is fusiform in shape with superficial fibers that are bipenniform and deep fibers that run straight (rectus) to the deep aponeurosis.
Where does the quad muscle attach?
Where are the quad muscles located? Your quad muscles are on the front of your thigh, above your knee and below your hip. Quad tendons attach them to your pelvis, hip bones, femur (thigh bones) and kneecaps .
What is the action of the rectus femoris quizlet?
It is attached to the hip and helps to extend or raise the knee . This muscle is also used to flex the thigh. The rectus femoris is the only muscle that can flex the hip.
What connects the quad to the hip?
Rectus Femoris
Attachments: Originates from the ilium, just superior to the acetabulum. It runs straight down the leg (the Latin for straight is rectus), and attaches to the patella by the quadriceps femoris tendon . Actions: The only muscle of the quadriceps to cross both the hip and knee joints.
Can you tear your rectus femoris?
When the rectus femoris is strained or tears, pain will immediately be felt at the top of the thigh, and in extreme cases there is a noticeable defect when the muscle is completely torn. Fortunately complete tears are rare . An MRI scan is normally requested to determine the extent of the injury.
What causes tight rectus femoris?
The most common knee problems associate with rectus femoris are: Muscle Strain : sudden overloading or over-stretching can cause rectus femoris strain. Muscle Tightness: tightness in rectus femoris is a common problem, particularly in people who spend much of the day sitting e.g. office workers.
What causes rectus femoris pain?
A rectus femoris tendon strain usually occurs whilst doing explosive activities such as running or jumping . The rectus femoris muscle is the large quadriceps muscle that runs down the center of the front of the thigh. It is a biaxial muscle meaning it crosses two joints; the hip and knee joints.
What muscle runs from hip to knee?
Sartorius : The sartorius muscle is a long thin muscle that runs down the length of your thigh from your pelvis to your knee. It’s the longest muscle in the human body and helps flex the knee and leg.
Where is hip flexor pain felt?
Hip flexor pain is usually felt in the upper groin region, where the thigh meets the pelvis . To avoid hip flexor pain, you should pay more attention to these muscles, Dr. Siegrist explains. When you are seated, your knees are bent and your hip muscles are flexed and often tighten up or become shortened.
What muscles flex the hip joint?
The hip flexors consist of 5 key muscles that contribute to hip flexion: iliacus, psoas, pectineus, rectus femoris, and sartorius.
What is the main function of rectus femoris muscle?
Function: The primary function is knee extension . It also assists with hip flexion. The rectus femoris can perform these two functions simultaneously. Innervation: Femoral nerve (L2–L4).
Which muscle connects your ilium to your thigh bone?
The gluteus medius , located deep to the gluteus maximus, runs from the ilium to the greater trochanter of the femur.
What muscle attaches at the iliac crest?
Many important abdominal and core muscles are attached to the iliac crest, including the hip flexors, the internal and external abdominal oblique muscles, the erector spinae muscles, the latissimus dorsi, the transversus abdominis, and the tensor fasciae latae .
What muscle is the prime mover of the hamstrings?
The antagonist to the quadriceps group is the hamstrings group of muscles located on the posterior thigh. This group consists of three muscles – the biceps femoris, semitendinosus and semimembranosus – and are the prime movers of knee flexion, and also rotate the knee when it is semi-flexed.
How do you test for rectus femoris?
How do you injure rectus femoris?
- Injury may be the result of overuse especially in sporting activities.
- Sudden motions that require “explosive” stress like bursting into a sprint.
- Forceful kicking activities.
How do you activate rectus femoris?
Where do the hamstrings attach?
Your hamstring muscles are located in the back of the thigh, starting at your hip and inserting to the knee. Hamstring tendons attach them to bones in your pelvis, knee and lower leg .
What does the vastus lateralis attach to?
It arises from a series of flat, broad tendons attached to the femur, and attaches to the outer border of the patella . It ultimately joins with the other muscles that make up the quadriceps in the quadriceps tendon, which travels over the knee to connect to the tibia.
What are the 4 quad muscles?
- the rectus femoris.
- the vastus lateralis.
- the vastus intermedius.
- the vastus medialis.
What is the origin of the rectus femoris in humans quizlet?
In the cat, the rectus femoris originates entirely from the femur. In the human, it originates from the hip bone .
What is a 2 joint muscle?
Biarticular muscles are muscles that cross two joints rather than just one, such as the hamstrings which cross both the hip and the knee. The function of these muscles is complex and often depends upon both their anatomy and the activity of other muscles at the joints in question.
What is the common insertion of the quadriceps femoris?
They originate at the ilium (upper part of the pelvis, or hipbone) and femur (thighbone), come together in a tendon surrounding the patella (kneecap), and insert at (are attached to) the tibia (shinbone) .
Where is the rectus femoris located?
Anatomy of the Rectus Femoris
Specifically, it is located on the anterior portion of the thigh muscle (in the very front) .
Where does the rectus femoris start?
