Explanation:

A typical adult human skeleton consists of the following 206 bones. Some people have slightly more or fewer. Some bones are called "proximal" meaning nearer the torso, some as "intermediate" and some as "distal" meaning farther.

In the skull (22):

Cranial bones:

frontal bones

Parietal bone (2)

temporal bones (2)

occipital bone

sphenoid bone

ethmoid bone

Facial bones:

mandible

maxilla (2)

palatine bone (2)

zygomatic bone (2)

nasal bone (2)

lacrimal bone (2)

vomer bone

inferior nasal conchae (2)

In the middle ears (6):

malleus (2)

incus (2)

stapes (2)

In the throat (1):

hyoid bone

In the shoulder girdle (4):

scapula or shoulder blade (2)

clavicle or collarbone (2)

In the thorax (25):

sternum

ribs (2 x 12)

In the vertebral column (24):

cervical vertebrae (7) incl. atlas & axis

thoracic vertebrae (12)

lumbar vertebrae (5)

In the arms (6):

humerus (2)

radius (2)

ulna (2)

In the hands (54):

Wrist (carpal) bones:

scaphoid bone (2)

lunate bone (2)

triquetral bone (2)

pisiform bone (2)

trapezium (2)

trapezoid bone (2)

capitate bone (2)

hamate bone (2)

Palm or metacarpal bones:

metacarpal bones (5 × 2)

Finger bones or phalanges:

proximal phalanges (5 × 2)

intermediate phalanges (4 × 2)

distal phalanges (5 × 2)

In the pelvis (4):

coccyx

sacrum

ossa coxae (hip bones or innominate bones) (2)

In the legs (8):

femur (2)

patella (2)

tibia (2)

fibula (2)

In the feet (52):

Ankle (tarsal) bones:

calcaneus (heel bone) (2)

talus (2)

navicular bone (2)

medial cuneiform bone (2)

intermediate cuneiform bone (2)

lateral cuneiform bone (2)

cuboid bone (2)

Instep bones:

metatarsal bone (5 × 2)

Toe bones:

proximal phalanges (5 × 2)

intermediate phalanges (4 × 2)

distal phalanges (5 × 2)

The infant skeleton has the following bones in addition to those above:

sacral vertebrae (4 or 5), which fuse in adults to form the sacrum

coccygeal vertebrae (3 to 5), which fuse in adults to form the coccyx

ilium, ischium and pubis, which fuse in adults to form the pelvic

206 HUMAN BONES

The skeleton

The human skeleton is made up of 206 bones, including bones of the:

  • Skull – including the jaw bone
  • Spine – cervical, thoracic and lumbar vertebrae, sacrum and tailbone (coccyx)
  • Chest – ribs and breastbone (sternum)
  • Arms – shoulder blade (scapula), collar bone (clavicle), humerus, radius and ulna
  • Hands – wrist bones (carpals), metacarpals and phalanges
  • Pelvis – hip bones
  • Legs – thigh bone (femur), kneecap (patella), shin bone (tibia) and fibula
  • Feet – tarsals, metatarsals and phalanges.

Bone Types:

There are four different types of bone in the human body:

  • Long bone – has a long, thin shape. Examples include the bones of the arms and legs (excluding the wrists, ankles and kneecaps). With the help of muscles, long bones work as levers to permit movement.
  • Short bone – has a squat, cubed shape. Examples include the bones that make up the wrists and the ankles.
  • Flat bone – has a flattened, broad surface. Examples include ribs, shoulder blades, breast bone and skull bones.
  • Irregular bone – has a shape that does not conform to the above three types. Examples include the bones of the spine (vertebrae).
