Front 1

Anatomy of A Long Bone

Back 1

- Longer than wide
- Shaft with heads at ends
- Composed of compact bone

Front 2

Spongy Bone

Back 2

- Also called cancellous bone
- Composed of trabeculae and lots of open space

Front 3

Compact Bone

Back 3

- Looks smooth and homogenous
- Dense

Front 4

Structure of A Long Bone

Back 4

1. Diaphysis (shaft)
2. Epiphysis ( end of long bone, composed of a thin layer of compact bone that encloses spongy bone)
3. Articular Cartilage ( Covers the epiphyseal surface in place of the periosteum)
4. Epiphyseal Plate ( a thin area of hyaline cartilage that provides for lengthwise growth of the bone during youth. Once bone stops growing this turns into a line of bone in adults)
5. Medullary Cavity ( A storage region for adipose tissue)
6. Endosteum ( Lines the shaft, covers the trabeculae of spongy bone and lines the canals of compace bone.)

Front 5

Frontal Bone

Back 5

- Anterior portion of cranium
- forms: forehead, superior orbit, and floor of anterior cranial fossa.

Front 6

Supraorbital foramen

Back 6

- Opening above each orbit
- Allows blood vessels and nerves to pass.

Front 7

Glabella

Back 7

- Smooth area between the eyes

Front 8

Parietal Bone

Back 8

- Posterolateral to the frontal bone, forming sides of cranium

Front 9

Sagittal Suture

Back 9

- Midline articulation point of the two parietal bones

Front 10

Coronal Suture

Back 10

- Point of articulation of parietals with frontal bone

Front 11

Temporal Bone

Back 11

- Inferior to parietal bone on lateral skull

Front 12

Squamos Suture

Back 12

Point of articulation of the temporal bone with the parietal bone

Front 13

Zygomatic Process

Back 13

A bridgelike projection joining the zygomatic bone anteriorly

Front 14

Mandibular Fossa

Back 14

Rounded depression on the inferior surface of the zygomatic process
