Axial Skeleton

Immovable joints, present only in skull

Coronal, Sagittal, Lambdoidal, Squamous

The suture between the parietal and frontal bones of the skull

The suture uniting the two parietal bones

Suture between the parietals and the occipital bone

Suture between the parietals and the temporal bone

The large cranial bone forming the front part of the cranium: includes the upper part of the orbits

Two skull bones between the frontal and occipital bones and forming the top and sides of the cranium

Thick bones forming the side of the human cranium and encasing the inner ear

A saucer-shaped membrane bone that forms the back of the skull

Butterfly-shaped bone at the base of the skull, holds all other bones together

A small bone located between the orbits in the skull, comprising part of the sinuses

Two bones on either side of the nose, of varying shape and size depending on genetics, irregularly shaped

Two irregularly shaped bones on either side of the skull; form the cheekbones

The bone that forms your upper jaw. The right and left halves are irregularly shaped bones that fuse together in the middle of the skull, below the nose, in an area known as the intermaxillary suture

Lower jaw bone, detached & movable, irregular bone

Entry points in the mandible bone for blood vessels

Thin trapezoidal bone of the skull forming the posterior and inferior parts of the nasal septum

Small irregularly shaped bones in the sides of the nasal canal

Small fragile bone making up part of the front inner walls of each eye socket and providing room for the passage of the lacrimal ducts; drains eyes to nasal

The large opening at the base of the cranium through which the spinal cord passes

Extends from the base of the temporal bone

A smooth conical projection of bone located at the base of the mastoid area of the temporal bone. It allows the attachment of muscles.

Hole in the side of the cranium which forms the ear canal

Small bump on occipital bone which serves as a muscular attachment point

Two bones in upper jaw, forming roof of mouth/hard palate

26 bones in total; Cervical, Thoracic, Lumbar, Sacrum, and Coccyx

Seven bones; bifid spinous (two bumps); first bone is called Atlas, second is called Axis.

First cervical vertebra, holds up skull, allows for nodding motion

Second cervical vertebra, allows for head-shaking motion, has a structure called a dens which is a bump.

Articulate with ribs, look like giraffe's face, downward spinous

Largest and strongest of the vertebrae; looks like moose's face; square spinous

Wedge-shaped bone consisting of five fused vertebrae forming the posterior part of the pelvis; permits articulation of two hip bones; contains many foramen for nerves

Tailbone; points inferiorly in those with birth canals, anteriorly in those without

Discs of cartilage between vertebrae which absorb shock

The placing of a vertical rod between two vertebrae, keeping the disc in place while eliminating the ability for those two vertebrae to bend

A painful slip of the fibrocartilage of the disc between spinal vertebrae; occurs most often in the lumbar region; causes disc to put pressure on spinal cord

An abnormal lateral curve to the vertebral column

An abnormal backward curve to the vertebral column; observed most commonly in the elderly due to muscular atrophy

12 pairs of ribs (24 in all), plus sternum

Flat bone which connects all ribs in the anterior face of the ribcage; Manubrium (top), body (middle, part with most of the rib connections), Xiphoid Process (very bottom tip, can break off during CPR and puncture lungs)

7 pairs-- connect directly to sternum

5 pairs, including floating ribs-- connect indirectly to sternum

2 pairs-- don't connect to sternum at all, connect only to thoracic spine; technically also false ribs

Hammer, anvil, stirrup; malleus, incus, stapes

Hammer ear bone

Anvil ear bone

Stirrup ear bone

Top of sternum

The part of the rib which articulates with the thoracic spine

Why are there 7 pairs of true ribs, 5 pairs of false ribs, and 2 pairs of floating ribs when there are only 12 pairs of ribs in all?
