The backbone, spine or vertebral column is made up of 26 small bones called the vertebrae.

The characteristics of bones include:

1. They are strong and rigid

2. They are composed of bone cells called osteocytes.

3. They are lightweight

4. They have a honeycomb-like matrix internally, which helps to give them rigidity.

5. They exist in various types and shapes.

6. They have the ability to grow and repair when damaged

7. They contain inorganic minerals such as calcium and phosphate

The two types of joints are the movable and immovable joints.

Ligaments are bands of tough elastic fibrous tissue around that found around the joints whose function is to link bone to bone, give support to joints as well as limit their movement.

Explanation:

The backbone, spine or vertebral column is made up of 26 small bones called the vertebrae. The 26 small bones include 24 separate vertebrae interspaced with cartilage, and then additionally the sacrum and coccyx. The vertebral column is divided into five regions: cervical, thoracic, lumbar, sacral and coccygeal regions.

A bone is a rigid tissue that is part of the skeleton in vertebrate animals. The characteristics of bones include:

1. They are strong and rigid

2. They are composed of bone cells called osteocytes.

3. They are lightweight

4. They have a honeycomb-like matrix internally, which helps to give them rigidity.

5. They exist in various types and shapes.

6. They have the ability to grow and repair when damaged

7. They contain inorganic minerals such as calcium and phosphate

Joints are the junctions where two bones meet. They serve various functions which include allowing for movement of the body and binding the skeleton together.

The two types of joints are the movable and immovable joints.

Ligaments are bands of tough elastic fibrous tissue around that found around the joints whose function is to link bone to bone, give support to joints as well as limit their movement.

  the unit of the measure =

explanation:

  the property that is quantified by the energy needed per of material to raise the temperature by one.

  si unit of energy = joule (j)

  si unit of temperature = kelvin (k)

  si unit of mass of material = kilogram (kg)

the property that is quantified by the energy needed per of material to raise the temperature by one is called specific heat.

the unit of specific heat is
