There are five types of bones :

1 Flat bones :

Like in skull, pelvis and thoracic cage.

Function : to protect internal organs.

2 Long Bones :
Longer and relatively less wide.

Function : to support the weight of the body and facilitate movement.

Like Femur, lower limbs, upper limbs. etc.

3 Short bones :

Like in wrist and ankle joints.

Function : provide stability and support.

4 Irregular bones

having complex shapes, do not fit into any above category.

Like in irregular bones present in vertebrae,
irregular bone present in pelvic named, pubis ilium etc.

5 sesamoid bones :

Like in tendons of the hands, knees, and feet.

sesamoid bones protects tendons from stress and wear.


Hope it's useful.

All the best

Types in the basis of shape:-

i) Long bones:- These bones typically have an elongated shaft and two expanded ends one on either side of the shaft.

ii) Short bones:- This bones are short on posture and can be of any shape. Most of named according to their shape.

iii) Flat bones:- This bones are flat in appearance and have two prominent surfaces.

iv) Irregular bones:- The shape of this bones is completely irregular and they do not fit into any category of shape.

v) Pneumatic bones:- Pneumatic bones can also be categorized under the irregular bones because they are also irregular in shape but since their is a difference between the two that is characteristically very important therefore they are often classified separately.

vi) Sesamoid bones:- These are not like the other types of bones because they are in the form of nodules embedded in tendons and joint capsules.

Types on the basis of development:-

i)Membranous bones:- These are also known as dermal bones and the process by which they ossify is called intra membranous ossification.

ii) Cartilaginous bones:- These bones are ossify from cartilage model and this type of ossification is known as intra cartilaginous ossification.

iii) Membrocartilaginous bones:- These bones ossify partly from cartilage and partly from mesenchymal condensations.

Types on the basis of region:-

i) Bones of axial skeleton:- These bones from the axial skeleton of human body. Examples are bones of skull, vertebral column, and thoracic Cage.

ii) Bones of appendicular skeleton:- These bones from the appendicular skeleton of the body. Examples of this type of bones are bones of the limbs and girdles of limbs.

Types on the basis of structure:-

According to Macroscopic approach

i) Compact bones:- The part of a bone where bone substance to bone space ration is a bigger quantity is called compact bone.

ii) Spongy bones:-The part of a bone where bone substance to bone space ratio is a smaller quantity.

According to Microscopic approach:-

i) Fibrous bone:- This have more fibre in them. In human they are found only in fetus.

ii) Lamellar bones:- A type of bone which are composed of thin plates of bony tissue.
