Thigh muscles-different muscles of the thigh

What are thigh muscles

The thigh has three sets of strong muscles: the hamstring muscles in the back of the thigh,
the quadriceps muscles in the front, and the extra muscles inside. The quadriceps and
hamstrings work together to straighten (stretch) bend and flex the leg. The extra muscles
pull the legs together.

The hamstring and quadriceps muscle groups are at greater risk of muscle damage as they
cross both hip and knee joints. They are also used for high-speed activities, such as track and
field events (running, obstacles, long jump), soccer, basketball, and soccer.

Muscle spasms usually occur when the muscle is stretched beyond the extremities, tearing
through the muscle fibers. These injuries often occur near the area where the muscle joins
the hard, connective tissue in the tendon. A direct blow to a muscle can also cause similar
injuries. Tightness in the thigh muscles can be very painful.

When the severity of the muscle injury subsides, the body’s tissues are at risk of recurrence.
It is important to allow the tissues to heal properly and follow the instructions for your
doctor’s appointment.

Thigh muscle can be divided into three parts:

  • First Muscles in the Anterior Compartment of the Thigh
  • Second Muscles in the Medial Compartment of the Thigh
  • Third Muscles in the Posterior Compartment of the Thigh.

Muscles in the Posterior Compartment of the Thigh.

The muscles in the back of the thigh are known as hamstrings. They consist of the biceps
femoris, semitendinosus, and semimembranosus, which form prominent muscles in the
middle and later behind the knee.

As a group, these muscles work by stretching the hips, bending at the knee. They are taken
to the heart by the sciatic nerve (L4-S3).

In this article, we will examine the structure of the muscles in the back thigh – their
attachments, internal care, and actions.

Muscles in Posterior

The muscles found inside the back of the thigh are the biceps femoris, semitendinosus and

Note: The hammer part of the adductor Magnus has the same action as these muscles, but
is located in the medial thigh.

Like the biceps brachii in the arm, the biceps femoris muscles have two heads – a long head
and a short head.

It is the very back of the tendons in the posterior thigh – a normal twoheaded
the tendon can be felt over time in the hind knee.

The long head emerges from the ischial tuberosity of the pelvis. The short head emerges
from the linea aspera to the posterior outer surface of the femur. Together, the heads form
a tendon, which is attached to the head of the fibula.

The main action is knee flexion. It also stretches the thigh at the waist, and then around the
waist and knees.

A long head occupied by the tibial part of the sciatic nerve, while the short head is occupied
by the normal fibular nerve part.


The semitendinosus is the most common muscle. It lies directly on the biceps femoris, and
covers most of the semimembranosus.
From the ischial distance of the pelvis, and attaches to the surface of the tibia.

Actions: Flexion of the leg at the knee joint. Expansion of the thigh at the waist. Inside you
rotate the thigh at the hip joint and at the leg where the knee meets.

Innervation: The Tibial part of neurological science.


The semimembranosus muscle is soft and broad. It is found under the semitendinosus.

From the ischial tuberosity, but does much more than the semitendinosus and biceps
femoris. It attaches to the medial tibial condyle.

Flexion of the leg from the knee joint. Expansion of the thigh at the waist. Inside you rotate the
thigh at the hip joint and at the leg where the knee meets.

Innervation: The Tibial part of neurological science.

The Muscles in the Anterior Compartment of the Thigh :

Hip stiffness can be divided into three categories; Posterior, medial, and anterior. Each part
has a separate function.

The muscles in the outer part of the thigh innervated by the femoral nerve (L2-L4), and as a
the general rule, extend the leg at the knee joint.

There are three major muscles in the outer thigh – the pectineus, sartorius, and quadriceps
femoris. In addition to these, the end of the iliopsoas muscle extends to the outer chamber.

The Muscles in the Medial Compartment of the Thigh

The muscles in the pelvic floor are known as hip adductors. There are five muscles in this
group; gracilis, regulator externus, adductor brevis, adductor longus, and adductor Magnus.

All medial thigh muscles are inserted internally by the nerveurur nerve, from the lumbar
plexus. The arterial supply passes through the Discoverurtery artery

Muscle Strains in the Thigh


A person who feels muscle pain in the thigh will often explain that the feeling of coming out
or snatching like muscle tears. The pain is sudden and can be severe. The area around the
injury may be softened when touched, with visible damage if blood vessels are also broken.
Inflammation and areas of ecchymosis (“black and blue”) usually extend below the thigh and
into the calf and thigh. This can happen even a day or two after an injury.

Medical examination

Your doctor will ask about the injury and examine your thigh for tenderness or injury. You
maybe asked to bend or straighten your knee and/or hip so that your doctor can confirm
the diagnosis.

An x-ray may be needed if there is a possible injury or another injury to the bone. Your doctor
may also order a resonance imaging (MRI) scan to continue examining the muscles and
tendons in your leg.

Muscle mass is calculated as its strength. Grade 1 type is less common and tends to heal
more easily, whereas type 3 is a painful tear that can take months to heal.


Take a break. Take a break from stressful work. Your doctor may recommend that you use
crumbs to avoid putting weight on your leg.
Ice. Use cold packs for 20 minutes at a time, several times a day. Do not apply ice directly to
the skin.
Pressure. To prevent further swelling, lightly seal the injured area with a soft bandage or ace
Height. To reduce swelling, lift your leg higher above your heart.

Your doctor may recommend an infertility anti-inflammatory drug, such as ibuprofen, for
pain relief. As pain and inflammation subside, physical therapy will help improve a range of
strength and strength. The muscle should be completely strong and free of pain before
returning to sports. This will help prevent further damage.
