S YSTEM
 The Musculoskeletal System is
composed of the
bones, joints, muscles, tendo
ns, ligaments, and cartilages.
These parts of the body are
prone to
strain, sprain, dislocation and
fracture.

3. S TRAINS
 Strains are injuries to
muscles and tendons due
to sudden or overexertion
of movements. The muscle
fibers are stretched and
the tendons torn. Pain is
felt by the victim.
Swelling, discoloration and
difficulty of movement of
the injured part are
observed. First aid for this
includes rest and
application of hot
compress.

5. D ISLOCATION
 Dislocation is a situation
where one or more of the
bones forming a joint slip
out of normal position. The
ligaments that hold these
bones in place are stretched
or torn loose. The joints
commonly dislocated are the
freely movable joints like the
lower jaw, shoulders,
elbows, wrists, fingers, lips,
knees, ankles and toes. First
aid includes immobilizing the
injured parts by using splints
before transporting the
victim.

6. After receiving first aid, an
injured person often requires
transportation to a medical
facility. As a first aider, you must
be responsible for making sure
that the victim is transported to a
safer place to prevent further
injury, pain and discomfort.
