Welcome to class lovelies!

THE HUMAN BODY (The skeletal system).

INTRODUCTION

In this topic, we will be learning about the human skeletal system and its uniqueness. At the end of the class, students should be able to know the features of the skeletal system, the various types of bones in the skeletal system and the function of the human bones within the skeletal system.

 

THE HUMAN BODY

The human body is everything that makes us up. Our body consists of the head connected to the torso by the neck. Attached to the torso are our arms and legs. The different parts of the human body work together in such a way that you can do all the wonderful things we normally do as humans including eating, walking, working, sleeping, studying or playing with our friends. For example:

1. The head is the center where all the activities carried out by your body starts from.

In the head are other parts attached to it such as the eye, nose, ear, mouth, etc.

1. The neck is not just the short bridge that joins our head to our torso but also goes all the way down to our lower back known as our spine. The neck not only allows us to turn our heads left and right but can also allow us to look up and down to see what is happening around us.
2. The shoulder supports the neck to carry the head. The shoulder blades on top of the rib cage that forms the rest of our body.
3. The rib cage houses the stomach, intestines and organs that sustains us.
4. The arms and legs are parts of our body that supports movement of any kind. Our arms help you to hold and move things. We use our legs to walk, run and move around or run from danger.

THE SKELETAL SYSTEM

 

The skeletal system includes all of the bones and joints in the body. The skeleton provides support and protection for the soft tissues that make up the rest of the body. The skeletal system also provides attachment points for muscles to allow movements at the joints. The total number of the bones in your body is 206.

TYPES OF BONES

The bones of the human skeleton are grouped by their shape:

 

1. Long bones, Examples are the femur (the leg).
2. Short bones, Examples are the bones of the wrist.
3. Flat bones Examples are the rib cage, the roof of the skull.
4. Sutural bones: They may be found between the flat bones of the skull. They vary in number, shape, size.
5. Sesamoid bones: They are found near the joints e.g. the knee.
6. Irregular bones: Irregular bones are found along the backbone and the hip region.

 

FUNCTIONS OF THE BONES

 

The skeletal system is the body system made up of bones and cartilage and performs the following responsibility for the human body:

 

1. Supports the body
2. Facilitates movement
3. Protects internal organs
4. Produces blood cells
5. Stores and releases minerals and fat into the body.

 

EVALUATION

Define the human body

List 5 bones found in the human body separate from the ones mentioned above.

 

SUMMARY

 

• The skeletal system is made up of bones and cartilages serving has many functions.
• The skeletal system in the human body is made up of 206 bones.

 

ASSIGNMENT

 

1. Describe two function of the bone as stated above
2. Draw and label the human head
3. List 5 bones that can be found in the human body
