Skeletal System Definition

Joint Dislocation - the internetwork of bones and joints that work together to make up the core foundation of our bodies. Adult human skeleton consists of 206 bones (208 if the sternum is considered as three bones).

Feet and Legs

The legs are made up of big long bones at the length of the legs and small bones around the ankles and feet

• Thighs have 2 femur bones
• Patella - knee cap
• Tibia and Fibula are the bones between the ankles and the knees

The ankles have many tiny bones (Tarsal bones)

Calcaneus (heel)

Talus

Navicular bone

Medial cuneiform bone

Intermediate cuneiform bone

Lateral cuneiform bone

Cuboid bone

Metatarsus bones connect the heel to the digits of the feet and the digits of the feet (phalanges) are:

• Proximal phalanges
• Pntermediate phalanges
• Distal phalanges

Hips, Back and Neck and Ribs

The neck and throat bone is called the Hyoid bone. There are ribs protect our front sides with 6 ribs on each side, In the pelvis (hips):

• Coccyx
• Sacrum
• Hip bone (innominate bone or coxal bone)

In the vertebral column is divided into 4 parts:

• 7 Cervical vertebrae
• 12 Thoracic vertebrae
• 5 Lumbar vertebrae
• Sacrum (5 fused vertebrae)

The sternum is the breast bone and be considered as three bones: manubrium, body of sternum (gladiolus), and xiphoid.

Shoulders, Arms and Hands

The shoulder is made up of 2 bones on each side: scapula (shoulder blade) and the clavicle which connects the shoulder to the neck area. The arm bone is the Humerus and the forearms have two bones: Radius and the Ulna.

The hands have many small bones

• Carpal (wrist) bones
  • Scaphoid bone
  • lunate bone
  • triquetral bone
  • Pisiform bone
  • Trapezium
  • Trapezoid bone
  • Capitate bone
  • Hamate bone
• Metacarpus (palm) bones
• Digits of the hands
  • Proximal phalanges
  • intermediate phalanges
  • distal phalanges

Skull and Face

The skull is made up of 8 bones called the Cranal Bones (skull bones)

• Frontal bone
• Parietal bone
• Temporal bone
• Occipital bone
• Sphenoid bone
• Ethmoid bone

The face is made up of 14 bones:

• Mandible
• Maxilla
• Palatine bone
• Zygomatic bone
• Nasal bone
• Lacrimal bone
• Vomer
• Inferior nasal conchae

Believe it or not, there are even three bones in each ear

• Malleus
• Incus
• Stapes
