2. Introduction
• The upper leg is the
region of the body
located between the hip
and knee joint. This
region of the body is
comprised of one long
bone, the femur, as well
as numerous muscles,
tendons, and ligaments,
including the hamstrings
and quadriceps.

3. • In clinical anatomy
the thigh muscles are
divided into three
groups: Anterior
muscles extend your
legs and flex your
thighs. Medial
muscles adduct and
rotate your thigh, and
posterior flex your leg
and extend your
thigh.

4. The anterior thigh muscles
• The muscles of
the anterior
part of the
thigh include
the quadriceps
group and a
few others.

5. The medial thigh muscles
• The muscles of
the medial part of
the thigh include
muscles that
bring the thigh
toward the
midline and
rotate it.

6. The posterior thigh muscles
• The three muscles
of the posterior
thigh are known as
the hamstring
muscles. They
extend the thigh
from a flexed
position and flex
the leg.

7. Injuries
• Hamstring string:

8. Exercises
• Leg Extensions
Main target: the quads or
quadriceps (the front
thighs).
• Start with knees bent at
90.
• Extend lower legs as far as
possible.
• Return to starting position
under control.

9. • Hamstring
Stretch
It's more
effective to
stretch one leg
at a time, so
you're less
limited by your
pain threshold.
Regular Splits
Stand with your feet about two
shoulder widths apart to each
side.
Use the hands for support. If you
can't place your hands on the
floor, then place both hands on a
chair seat directly in front of you.
Gradually lower yourself into the
stretch for one to 1.5 minutes.
Feel the stretch in your inner
thigh (groin or adductors).
Use your hands to press up out of
this stretch when finished.

10. Injuries
Quadriceps
contusion
The adductor strain

11. Thorax

12. Pectoralis
• The pectoralis minor is a thin, triangular muscle, situated at the upper part of
the chest, beneath the pectoralis major in the human body.
• The pectoralis major is a thick, fan-shaped muscle, situated at the chest of the
human body. It makes up the bulk of the chest muscles in the male and lies under
the breast in the female.

13. Serratus anterior and Intercostals
• The Serratus anterior muscle is a muscle that originates on the surface of
the 1st to 8th ribs at the side of the chest and inserts along the entire
anterior length of the medial border of the scapula.
• Intercostal muscles are several groups of muscles that run between the ribs, and help form
and move the chest wall. The intercostal muscles are mainly involved in the mechanical
aspect of breathing. These muscles help expand and shrink the size of the chest cavity when
you breathe.
