What is the human skeleton in detail?

The human skeleton is different from animal. There are two kinds of animal skeletons, namely: the outer frame and the inner frame. The outer skeleton is outside the body such as clams and shrimp which have an outer skeleton in the form of a shell.

The function of the shell is to protect the soft bodies of clams and shrimp. On the other hand, orangutans and giraffes have internal skeletons. The skeleton is covered by flesh and skin.

Humans have an internal skeleton. The skeleton is composed of hard bones. The arrangement of the bones that form the human body.

The functions of the human skeleton include:

1. Upright body
2. Gives shape to the body
3. Place of attachment of the muscles of the body
4. Protects important body organs (brain, lungs, and heart)

The framework strengthens our body. Without a framework, our bodies will be soft and stick to the ground.

The Human Skeleton is grouped into Three Major Groups, namely:

1. Skeleton Head (Skull)

The skull consists of flat bones that are connected to each other to form a "helmet" that protects the brain. This framework protects the brain, eyes, ears, nose and oral cavity.

2. Body Frame

The body frame consists of:

1. Sternum
2. Rib
3. Spine
4. Shoulder Band Bone
5. Pelvic Bracelet Bone

The body's framework functions to protect the heart and lungs

3. Skeletal Limb

The limb frame consists of two parts, namely:

1. Bones of the Upper Limb (Hand)
2. Lower Limb (Leg) Bones

The skeleton of the limbs functions as a means of locomotion.

In addition to the several functions already described, the skeleton also helps us move.

How do hard and stiff bones move?

A bone cannot move alone. Movement occurs because there are muscles and joints in our body. Joints are where two bones meet.

Motion joints are divided into four types, namely:

1. Hinge Joint

This joint is a joint that only allows movement in one direction

Example: Knees

2. Bullet Joints

This joint allows movement in all directions.

Example: Shoulders

3. Saddle Joint

This joint allows movement in both directions.

Example: Palm and Thumb Bones

4. Rotary Joints

This joint allows rotational movement.

Example: Neck Bone. Skull, between the Eight Bones and the Lever.

We must be able to maintain and care for our skeleton so that it grows properly and normally.

How to Take Care of the Frame is very easy and simple, including:

1. Sit up straight while studying
2. Stand up straight
3. Not Studying and Reading While Lying Down
4. Eat foods that contain lots of phosphorus and lime, such as milk, eggs and vegetables.
5. Exercising so that the muscles and bones of our body become strong.

Bones also have several abnormalities in the spine caused by bad sitting posture, namely:

1. KYPHOSIS

Kyphosis is a disorder caused by the spine bending backwards

2. SCOLIOSIS

Scoliosis is a disorder caused by a curvature of the spine to the left or right

3. LORDOSIS

Lordosis is a deformity resulting from a forward curvature of the spine

What if we don't take good care of our bones?

If we don't take good care of our bones, our skeleton will experience disease disorders, including:

1. Abnormal Frame Shape

This happens because of the wrong sitting or standing posture

2. Bone Loss Disease (Osteoporosis).

This happens because the bones lack calcium and phosphorus

3. Broken Bones due to Accidents

This happens due to traffic accidents, when working, or when doing activities.

4. Polio Disease

This disease occurs due to the polio virus

From the description above, we can draw conclusions, namely:

1. The human skeleton consists of three parts, namely the head frame, the body frame, and the limb frame.
2. The function of the skeleton is to give shape to the body, straighten the body, protect the pending organs, and provide a place for muscles to attach
3. Joints are joints between one bone and another. With joints, humans can move their limbs.
4. Maintaining bone growth and health can be done by adopting good standing, sitting and sleeping habits, as well as consuming foods and drinks that contain lots of calcium
5. Bone diseases and disorders can be caused by viruses or germs, wrong body position, and collisions or accidents.

In addition, we also need to know that:

1. The human nose and earlobes continue to grow as cartilage
2. At the deepest part of the bone, there is Bone Marrow, where Blood Cells are formed
3. Children's bones have a lot of adhesive, so they are easily connected when they are cracked or broken, while adult bones are more calcified, so they are difficult to reattach.
4. The femur is the longest bone in the human skeleton
