MUSCULOSKELETAL SYSTEM

2. Skeletal system
The skeletal system supports the framework of the human body. It
helps the body in various ways.
 It provides the body support and form
 It facilitates movement together with the muscular system.
 It protects the delicate organs inside the body.
 It stores minerals for body use, especially calcium and
phosphorus.
 It produces blood cells.

3. What are the two
major divisions of
skeleton?

4. Skeletal organization The skeleton has two major divisions: the
AXIAL SKELETON and the APPENDICULAR
SKELETON.
The axial skeleton is represented by the
bones and cartilages of the head, neck,
and trunk.
The appendicular skeleton is represented
by the bones of the upper and lower
limbs. The upper limbs include arms,
forearms, and hands. The lower limbs
include the thighs, legs, and feet.

5. Ligaments and
tendons

6. JOINTS
It is a point where two bones meet and are connected
together by a ligament. There are three kinds of joints
according to the amount of movement they can do–
IMMOVABLE JOINTS, SLIGHTLY MOVABLE and
MOVABLE joints.
Immovable (Synarthrosis)-
Such joints don’t allow movement because bones are
rigidly joined together.
Slightly movable (Amphiarthrosis)
They allow limited or slight movement.
Freely movable (Diarthrosis)
Also known as synovial joints. Allow a wide range of
movement.

7. MUSCULAR SYSTEM
Muscular system consists mainly of muscles
as its organ. The basic actions of the
muscles are contraction and relaxation.

8. TYPES OF MUSCLE TISSUE

9. MUSCLE STRAIN
A damage in the ligaments that may be
caused by twisting of the joints. It mostly
occurs in the ankle and knee joints.

MUSCULOSKELETAL SYSTEM
SPRAIN
Results when a muscle is overstretched
Thus, it is also called muscle pull.
