Quadriceps : Parts of the body

                                          A to Z 2019

The  quadriceps femoris also called the quadriceps extensor, quadriceps (or quads  ) is a 

large muscle group that includes the four prevailing muscles on the front of the thigh.
It is the great extensor muscle of the knee, forming a large fleshy mass which covers the 

front and sides of the femur. The name derives from Latin four-headed muscle of 

the femur.
It is subdivided into four separate portions or 'heads', which have received distinctive 

Rectus Femorisoccupies the middle of the thigh, covering most of the other three 

quadriceps muscles. It originates on the   illum . It is named from its straight course.

The other three lie deep to rectus femoris and originate from the body of the femur, 

which they cover from the trochanters to the condytes.
Vastus Lateralis is on the lateral side of the femur (i.e. on the outer side of the thigh)
Vastus Medialis  is on the medial side of the femur (i.e. on the inner part thigh).
Vastus Intermedius lies between vastus lateralis and vastus medialis on the front of the 

femur (i.e. on the top or front of the thigh), but deep to the rectus femoris. Typically, it 

cannot be seen without dissection of the rectus femoris.

There is a fifth muscle of the quadriceps complex that is often forgotten and rarely 

taught called articularis genus.
All four quadriceps are powerful extensors   of the knee   joint. They are crucial in 

walking, running, jumping and squatting  . Because the  rectus femoris   attaches to the 

ilium, it is also a flexor   of the hip. This action is also crucial to walking or running as it 

swings the leg forward into the ensuing step. The quadriceps, specifically the vastus 

medialis , play the important role of stabilizing the  Patella  and the knee joint during gait
In strength training  , the quadriceps are trained by several leg exercises. Effective 

exercises include the  squat  and leg press. The isolation movement (i.e. targeting solely 

the quadriceps) is the leg extension exercise.
In body building communities, this muscle is colloquially referred to as the "leg triceps.
In modern English usage, quadriceps is used in both singular and plural.

                                     8 Exercises to Help Your Knees
  1. Straight Leg Raises. If your knee's not at its best, start with a simple strengthening exercise for your quadriceps, the muscles in the front of the thigh. ...
  2. Hamstring Curls. ...
  3. Prone Straight Leg Raises. ...
  4. Wall Squats. ...
  5. Calf Raises. ...
  6. Step-Ups. ...
  7. Side Leg Raises. ...
  8. Leg Presses.

As with most orthopedic injuries, the initial symptom of a quadriceps strain, partial muscle tear, or tendinitis/tendinosis is pain and tenderness. There may also be swelling  and decreased range of motion that may result in a limp. This pain may be acute in onset, or it may arise gradually and become progressively more painful with activity.
If there is a complete rupture of the quadriceps or patellar tendon, in addition to pain, the patient will be unable to fully extend the knee because the connection of the quadriceps muscle to the bone has been lost.
Compartment syndrome presents with intense pain, often out of proportion to the physical examination. There may be decreased range of motion of the leg and changes in sensation in the leg and foot.
Most quadriceps injuries can be treated with RICE (rest, ice, compression, and elevation). However, compartment syndrome is a surgical emergency, and many cases of tendon rupture will also require surgical management.
Crutches or other gait-assist devices might be needed depending upon the level of pain and whether or not the individual can weight-bear on the injured leg.
After a short period of rest, most people can start returning to normal function as pain allows. However, for athletes or for those who lift or repetitively bend/squat at work or home, physical therapy might be needed to regain range of motion and strength in the injured leg.

  2. I actually learned about a new body part today. My knowledge about quads was almost nil and I go back from your page quite enlightened

  3. Thanks for the exercices, I will try right now!

  4. I just started doing yoga, and a lot of poses work these muscles, which also mean they hurt a lot... :D

    1. They will hurt only in the beginning. As one continues practicing daily there will be flexibility and ease in the body. Yoga is very beneficial for the body and I have been doing it for the past 15 years.

  5. For the first time, I have read so much about Quadriceps. Thanks for an informative post, Kalpana!

  6. What I am more interested in is how to get rid of all the excess fat around them! :P :P :P

    1. Fat piles up easily and it stays. difficult ( but not impossible) to shed it. Thanks Chicky K.

  7. Thanks for posting details about Quadriceps. Also nice thing that you posted exercises to help knees and RICE treatment. Learning a lot through these posts Kalpana!

  8. Thanks for those simple exercises. Never thought we can build our quadriceps using these simple exercises too

    1. With constant practice , all exercises become simple. Thanks Suhavijay.


please show some love......
