Explanation

• Humans are born with around 300 bones, but as they grow and develop.
• Some of these bones fuse together, resulting in a total of 206 bones in the adult human skeleton.
• This process of bone fusion, called ossification.

Explanation

The hardest bone in the human body is the Femur.

The femur, or thigh bone, is the human body's longest, thickest, and strongest bone.

It is designed to support the weight of the body during movement.

The clavicle, or collar bone, is the skin's softest and weakest bone.

Explanation

The smallest bone in the human body, the stapes, is located in the ear.

It is part of the middle ear and helps transmit sound vibrations.

The largest bone is the femur, or thigh bone, which supports the weight of the body.

Explanation

The human body typically has 206 bones

At the time of birth, there are 270 bones which fuse with time to come to a total of 206 bones.

The total bones of our body can be divided into:

• the axial skeleton (80) 
• the appendicular skeleton (126)

The newborn child has 300 bones.

Longest bone: Femur (thigh bone)

Shortest: Stapes (one of the 3 small bones inside the ear)

The human head has 22 bones.

Explanation

Goiter is caused by iodine deficiency.

It results in an enlarged thyroid gland.

Iodine deficiency can cause mental retardation in children.

Particularly if the deficiency occurs during fetal development or early childhood.

This is because iodine is essential for brain development and thyroid function.

The effects of the thyroid come from two iodine-containing hormones.
