The document provides information about the human skeletal system. It discusses the bones that make up the skull, spine, rib cage, shoulder girdle, pelvis, arms, legs, hands, and feet. It describes the functions of the skull, spine, rib cage and pelvis in protecting internal organs. It also mentions that the large, thick leg bones provide support for the entire body. The document includes review questions about the skeletal system and its functions, as well as activities for connecting pictures of the skeletal system and observing joint movements.

7. Let’s do Activity
# 1. You connect
the cut out
pictures of the
human skeletal
system.

28. The skull gives shape to your head. It
is made up of several bones, your
cheekbone or the zygomatic bone, part
of the nose or the nasal bone, and the
jawbone or the mandible. The skull
encases the brain protecting it from
direct danger.

32. Backbone or the Spine

33. The backbone or the spine. The spine is
composed of 33 hollow bones called the
vertebrae. They are stacked on top of
each other and form a tube that protects
the spinal cord. It also helps support the
weight of the head and body.

37. The Rib Cage

38. The rib cage gives shape to
the trunk. There are 12 pairs of
ribs which protects the heart,
lungs, and liver are protected by
the rib cage. In front, the ribs
are connected by the sternum,
at the back; they are connected
to the upper spine.

42. The Shoulder Girdle

45. The shoulder girdle connects the
upper limbs to the axial skeleton. The
clavicle or collarbone and the scapula
or shoulder blade make up the
shoulder girdle.

49. The pelvic bone carries most of the
weight of the upper body. It also
protects some of the organs like the
urinary bladder, female reproductive
organs, and the rectum.

50. Arms and Legs Bones

51. Arms and legs are made up of long
bones. These include the humerus
(upper arm bones), radius and ulna
(lower arm bones), femur (thigh
bones), tibia and fibula (lower leg
bones). The large, thick leg bones
provide support for the entire body.

54. Hand and Feet Bones

56. Hands and feet are made up of short
bones. Many smaller bones form the
wrists, ankles, fingers, and toes.

59. Encircle the letter of the correct answer.
1. Which of these is NOT a job of the skeletal
system?
A.) support and give shape to the body
B.) makes blood cells
C.) removes wastes from the body
D.) produces blood
2. The skeletal system functions as _______.
A) growth C) support and protection
B) nutrition D) respiration

60. 3. One of the minerals that make up bones is
__________.
A. Aluminum C. magnesium
B. calcium D. sodium
4. It is made up of several bones, your cheekbone
or the zygomatic bone, part of the nose or the nasal
bone, and the jawbone or the mandible.
A. skull C. backbone or the spine
B. rib cage D. pelvic bone

61. 5. It carries most of the weight of the upper body.
It also protects some of the organs like the urinary
bladder, female reproductive
organs, and the rectum.
A. rib cage C. backbone or the spine
B. pelvic bone D. skul
