Описание: I forgot to mention Patella (knee cap) Skeletal System have 206 Bones+ Cartilages

Firstly we have axial skeleton and appendicular skeleton.

Then in the skull we have cranium which has frontal bone, parietal bone,temporal bone. And at the back we have occipital bone, ethmoid and sphenoid bone.

Talking about the face we have mandible and maxilla, nasal, lacrimal bones, and zygomatic bone. In our jaw we have hyoid bone and inside our ears we have three types of

bones:-

1. malleus

2. Incus

3. Stapes

In the front of the body we have sternum and in the back which is our spinal cord called has vertebral column.

In vertebral column there are 5 divisions:-

1. Cervical

2. Thoracic

3. Lumbar

4. Sacrum

5. Соссух

In the front we have ribs

Ribs which are connected both in the front and back of the body so they are called as true ribs.

Now if you look at the 8th 9th and 10th number ribs, they connect to the 7th rib so therefore they are called as false ribs.

Now if you look at the 11th and 12th rib, they are not connected thereby called as floating ribs.

Now let's talk about the hands and legs.

We have humerus and femur. In the hands we have radius and ulna bone and in the legs we have tibia and fibula bone.

In our wrists we have carpal bones and in our ankles we have tarsal bones.

In our palm we have metacarpal bones and foot we have metatarsal bones.

In our fingers and toe fingers we have phalanges.

Our hands and legs are attached to our axial skeleton with the help of girdles. At the top we have pectoral girdle and at the pelvic region we have pelvic girdle.

Pectoral Girdle - Clavicle and Scapula

Pelvic Girdle- 2 Coxal Bones (Ilium, Ischium, Pubis)

Sphenoid and Ethmoid- Part of Cranial Bones !! I forgot to mention phle isliye baad mai mention kiya h !!!
