The document discusses the skeletal and muscular systems of the human body. It explains that the skeletal system is made up of bones and cartilage and provides shape, support, protection of organs, movement, and storage of minerals to the body. It also describes that the skeletal system includes the skull, vertebral column, ribs, and limbs. The muscular system works with the skeletal system to allow movement through contraction of muscles and tendons.

SCIENCE

2. It is the movement of the
entire body from one
place to another.

3. The movement that does not
involve complete shifting of body is
called movement of curvature.
Example; bending, lifting etc.

7. Allah swt has designed 2 systems
for our body’s movement
Muscular
System

8. The skeletal system is made
up of 2 parts:
Bone
(is hard)
Cartilage
(is Elastic
and soft)

11. FUNCTIONS OF THE SKELETON SYSTEM
• Shape and support to the body.
• Protects the soft and delicate vital
organs of the body.
• Movement of the body.
• Some bones enclose bone marrow-a
blood-forming tissue.
• Bones store calcium and phosphorus
making them strong and hard.

12. The skeleton is of two types:
Endoskeleton-
Skeleton within the
body
Exoskeleton-
Skeleton outside the
body

14. Usually insects have
EXOSKELETONS.

15. The skeletal system is made up
of bones, joints and connective
tissue.

COLUMN:

18. RIBS: 12 in number
10 fixed, 2 floating.

21. JOINTS

22. Skeletal

Joints
Fixed
Ribs, joint to the
sternum, bones of skull
movable
ball and socket hinge pivot gliding
partially movable;
joints in vertebral
column.

24. WHAT ARE TENDONS
AND LIGAMENTS?

25. Muscles help in movement only by
contracting

28. THE MOVEMENT OF A SNAKE:

31. Do they not see the birds above them with
wings outspread and [sometimes] folded in?
None holds them [aloft] except the Most
Merciful. Indeed He is, of all things, Seeing.
