DISTRIBUTION OF BONES

In Axial skeleton - There will be 80 bones. It includes skull bones(29), vertebral column(26), Rib cage(25).

In Appendicular skeleton - There will be 126 bones. It includes Upper limb (64 bones), Lower limb (62 bones).

Firstly we will discuss about Axial skeleton 🦴

1. Skull - cranium(8) + face(14) + Ear ossicles(6) + neck bone(1)

Cranium - 1 frontal bone + 2 parietal bone + 1 occipital bone + 2 temporal bone + 1 sphenoid bone + 1 ethmoid bone.
Face - 2 nasal + 2 maxilla + 2 zygomatic + 1 mandible + 2 inferior nasal concha + 1 vomer + 2 lacrimal + 2 Palatine bones.
Ear ossicles - 2 malleus + 2 incus + 2 stapes
Neck bone - 1 hyoid bone.

2. Vertebral column - Cervical (7) + Thoracic (12) + lumbar (5) + Sacrum (1) + Coccyx (1)

3. Rib cage - 12 pair ribs ( Totally 12 x 2 =24 bones) + Sternum bone (1).

Secondly, We will discuss about Appendicular skeleton🦴

1. Upper limb - Pectoral girdle (4) - 2 clavicle + 2 scapula

Arm (brachium) = 2 Humerus

Forearm ( antebrachium) = 2 radius + 2 ulna

Hand (Manus) = 16 carpels + 10 meta carpels + 28 phalanges.

2. Lower limb - Pelvic girdle ( 2 Hip bones)

Thigh = 2 femur

Knee = 2 patella

Leg = 2 tibia + 2 fibula

Foot = 14 Tarsals + 10 metacarpels + 28 phalanges.

Appendicular skeletons are taken in account of both left and right side together. So, totally there are 206 bones in human adults.

In future, distribution of muscles, nerves, arterial and venous supply will be uploaded in region wise manner. 😇
