4. THE
SKELETAL
SYSTEM
(S6LT-IIab-1)

5. The human body is made up of
different kinds of bones. These
bones are called skeleton. The
human skeleton is the internal
framework of the body. The adult
human skeleton consists of 206
bones that are connected to one
another by ligaments.

6. At birth, infants have around 300
bones fused together when they
become adults. These bones
work together as a system called
a skeletal system. The skeletal
system serves as the framework
of the body.

7. Its major functions are body
support, facilitation of
movement, protection of internal
organs, storage of minerals and
fats, and blood cell formation.

8. The skeletal system is mainly
composed of bones which are
classified into two divisions, the
axial and the appendicular
skeleton.
SKELETAL SYSTEM

9. The axial skeleton includes the
skull, vertebral column, ribs, and
sternum. These bones form the
axes or framework of the trunk
and head.
SKELETAL SYSTEM

10. The appendicular skeleton
includes the bones of the
shoulder, arms, hands, hips,
legs, and feet.
SKELETAL SYSTEM

11. SKELETAL SYSTEM

12. All other bones of skeletal
system are classified into 4 as
shown in the table:
SKELETAL SYSTEM

13. SKELETAL SYSTEM

14. One of the axial skeletons is the
skull which consists of cranium
and facial bones. The cranium is
made up of eight bones joined
together to form a rigid case that
protects the brain.
SKELETAL SYSTEM

15. The face is made up of 14 facial
bones. The eye socket protects
the eyeball while mandible or
jawbone is movable bone that
holds the teeth.
SKELETAL SYSTEM

16. The spinal column or vertebrae
(neck and backbone) are irregular
bones that protect the spinal cord
while the ribcage protects the
lungs and the heart. Vertebrae are
arranged on top of the other and
move over each other slightly.
SKELETAL SYSTEM

17. There are 33 vertebrae in the
spinal column of a child and 26 in
an adult. This is so because as
the child grows, the last seven
bones join together to form just
two bones.
SKELETAL SYSTEM

18. Ribs are the bones at the side of
the chest. There are 12 pairs of
ribs. The upper 7 pairs are the true
ribs because they are connected to
the breastbone and the last two
pairs are not connected. These ribs
are called floating ribs.
SKELETAL SYSTEM

19. The shoulder has the collarbone
found in front of it. Scapula is the
shoulder bone found at the back of
your shoulder.
SKELETAL SYSTEM

20. The appendages found in the
lower extremities are
composed of pelvic bones.
Pelvic bones support the
lower parts of the body and aid
the movement of the legs.
SKELETAL SYSTEM

21. The upper arms have one long
bone called the humerus and
two bones in the lower arm are
known as the radius and ulna.
Radius or radial bone is one
of the two large bones of the
forearm.
SKELETAL SYSTEM

22. The upper arms have one long
bone called the humerus and
two bones in the lower arm are
known as the radius and ulna.
SKELETAL SYSTEM

23. Radius or radial bone is one
of the two large bones of the
forearm. The other bone is the
ulna. The ulna is usually
slightly longer than the radius
while the latter is usually
thicker.
SKELETAL SYSTEM

24. The wrist connects the hand to
the forearm. Each wrist or
carpal consists of 8 bones. The
palm or metacarpal has 5
bones.
SKELETAL SYSTEM

25. The wrist connects the hand to
the forearm. Each wrist or
carpal consists of 8 bones. The
palm or metacarpal has 5
bones.
SKELETAL SYSTEM

26. Inside the bones are bone
marrows that are very
important for the body to
manufacture blood cells. Bone
marrows are of two types, the
red bone marrow and the
yellow bone marrow.
SKELETAL SYSTEM

27. The red bone marrow is found
in the humerus, femur, pelvis
and vertebrae while the yellow
bone marrow is found in many
other bones.

30. The human skeletal system has
several important functions.
1. Support -The skeletal system
provides the framework which
supports and maintains shape of
the body. It gives the body much
needed support.
SKELETAL SYSTEM

31. 2. Protection -The skeletal
system protects the internal organ
of the body.
3. Movement- The skeletal
system provides an attachment for
the muscle which makes body
movements possible.
SKELETAL SYSTEM

32. 4. Storage and Supply- The
skeletal system stores important
minerals like calcium and
phosphorus and produces both
red and white blood cells.

78. THE
MUSCUSKELETAL
SYSTEM
(S6LT-IIab-1)

79. The Musculoskeletal System
consists of the muscular system
and skeletal system. These two
go together because their
functions are interrelated.
MUSCUSKELETAL SYSTEM

80. Aside from muscles and bones of the
skeleton, the Musculoskeletal System also
consists of cartilages, tendons, ligaments,
joints and other connective tissues that
support and bind tissues and organs
together. Its primary functions include
supporting the body, allowing
movement and protecting vital organs.
MUSCUSKELETAL SYSTEM

81. 1. Skeletal Muscles are voluntary
muscles that are attached to the
bones of the skeleton. They are
striated or stripped muscles. They
produce movement in the different
parts of the skeleton. Biceps and
triceps are examples of skeletal
muscles for they move the arms.
MUSCUSKELETAL SYSTEM

82. 2. Smooth Muscles are non-
striated involuntary muscles
found in the linings of the
stomach, intestines, and
bladder.
MUSCUSKELETAL SYSTEM

83. 3. Cardiac Muscles are
striated involuntary muscles
found in the walls of the
heart.
MUSCUSKELETAL SYSTEM

84. To allow movements, different bones are
connected by joints which are connected
to other bones and muscle fibers through
connective tissues such as tendon,
ligament, cartilage and joint.
MUSCUSKELETAL SYSTEM

85. Tendon is a band of tissues that
connects muscle to the bone.
Ligament is an elastic band of
tissues that connects bones to
other bones. It provides stability
to the joint.
MUSCUSKELETAL SYSTEM

86. Cartilage is a soft, gel-like
padding between bones that
protects joints and facilitates
movement.
MUSCUSKELETAL SYSTEM

87. Joint is the place where
two bones meet and come
together. It allows us to
move in different ways such
as walking, running,
climbing and others.
