4. Introduction
01
❖ basic framework of a body
❖ the entire body are built around the hard framework of
skeleton
❖ combination of all the bones and tissues associated with
cartilages and joints
❖ almost all the rigid or solid parts of the body are the main
components of the skeletal system
❖ joints play an important role in the skeletal system
6. Protects the brain and
provides an anchor for
tendinous and muscular
attachments of the muscles
of the scalp and face.
Provides support for the
weight of your head,
surrounds and protects your
spinal cord, and allows for a
wide range of head motions.
Protects the heart, lungs,
and major blood vessels.
Also serves as an
attachment point for ribs
and clavicles.
Serve as a point for
muscular attachment.
1) SKULL 2) CERVICAL VERTEBRAE 3) MANUBRI STERNI
A point of attachment for
muscles and bones in the
chest and shoulders and
helps protect vital organs
such as the heart and lungs.
Provide stability for your
back and spinal column and
allow for a point of
attachment for many
muscles and ligaments.
4) STERNUM 5) XIPHOID PROCESS 6) LUMBAR VERTEBRAE
03 Bones Function
7. Forms the upper part of the
hip bone, providing support
for the body and attachment
points for muscles.
Forms the posterior pelvic
wall and strengthens and
stabilizes the pelvis.
Forms the front part of the
hip bone, joining the other
two bones to form the
pelvis, supports the urinary
bladder and reproductive
organs.
Supports the body's weight
and allows for movement at
the hip joint. The longest
and strongest bone in the
body.
7) ILIUM 8) SACRUM 9) COCCYX
Insertion site for multiple
muscles, ligaments, and
tendons.
Protects the knee joint and
provides leverage for the
quadriceps muscle to move
the legs.
10) PUBIS 11) FEMUR 12) PATELLA
03 Bones Function
8. Provide support, stability,
and flexibility to the foot.
Allowing for various
movements such as
dorsiflexion, plantarflexion,
inversion, and eversion.
Form the structure of the
midfoot and provide support
during walking and standing.
Surrounds and provides
mechanical protection for
the eye and soft tissue
structures related to it.
Humidify and warm the
inspired air. Also, as the air
passes through, the nasal
cavity removes minute
airborne particles and other
debris before the air reaches
the lower airways.
13) TARSUS 14) METARSUS 15) PHALANGES FOOT
Provide support, balance,
and propulsion during
walking and running.
Supports the shoulder,
allows movement of the
arms, and protects major
blood vessels and nerves.
16) ORBITAL CAVITY 17) NASAL CAVITY 18) CLAVICLE
03 Bones Function
9. Protraction, retraction,
elevation, depression,
upward rotation, and
downward rotation.
Protects the chest cavity,
particularly the heart and
lungs. However, the main
function is to aid respiration.
Along with the radius,
supports the structure of the
forearm and allows for
rotation of the wrist and
forearm.
Along with the ulna,
supports the structure of the
forearm and allows for
rotation of the wrist and
forearm.
19) SHOULDER BLADE 20) RIB 21) HUMERUS
Supports the structure of
the arm and allows
movement at the shoulder
and elbow joints.
Form the wrist joint and
allow for movement of the
hand.
22) ULNA 23) RADIUS 24) CARPUS
03 Bones Function
10. Form the structure of the
palm of the hand. The
metacarpals also form a
transverse arch that allows
the fingertips and thumb to
be brought together for
manipulation.
Form the fingers and thumb,
allowing for grasping and
manipulation.
Supports the body's weight
and allows for movement at
the knee joint, commonly
known as the shinbone.
25) METACARPUS 26) PHALANGES HAND
27) FIBULA
Provides stability to the
ankle joint and serves as an
attachment point for
muscles involved in foot
movement.
28) TIBIA

11. Conclusion
04
❖ Bones are an important part of the musculoskeletal system
and serve many core functions, as well as supporting the
body's structure and facilitating movement.
