Cylindrical bones
Long bones
Bones that are longer than they are wide
Long bones
Where are long bones usually seen?
Usually seen on extremities (eg. tibia, phalanges, femur, fibula)
Bones that are as long as they are wide, sometimes having a cuboidal shape
Short bones
Bones that are sheet-like
Flat bones
Flat bones are usually — than flat
curved
Flat bones can act as:
1.
2.
- Armor; protection for internal organs (ex. scapula)
- Attachment for muscles (ex. sternum and ribs)
Bones that are complex in shape
Irregular bones
Example of irregular bones
Vertebral bones
Forms the central axis of the skeleton
Axial skeleton
Examples of axial skeleton
skull
vertebral column
ribs
sternum
Word that means line
“axial”: axis → line
Bones of the extremities, pectoral girdle/ shoulder girdle, and pelvic girdle
Appendicular skeleton
What makes up the appendicular skeketon?

Pectoral girdle/ shoulder girdle
Pelvic girdle
What makes up the shoulder girdle?
Scapula and clavicle
Other term for shoulder girdle
Pectoral girdle
Refers to the extremities of the body
Appendage
Bones connected by coronal suture
Frontal bone- parietal bone
Bones connected by squamous suture
Parietal bone- temporal bone
Bones connected by lamboidal suture
Parietal bone- occipital bone
Suture that connects right to left portions of the parietal bone
Sagittal suture
Compare sphenoid bone and temporal bone
Sphenoid bone: closer to the eyes; smaller that temporal
Temporal bone: closer to the ears
Other term for acanthion
