Where is the axial skeletal division?
From our head medial to the trunk and finishing at the coccyx.
Where are the appendicular divisions?
Upper and lower limbs as well as connections to the hips and shoulders.
What cranial bones cover the front and side lobes of the brain?
Frontal bone.
Parietal bone.
Which cranial bone covers the ear region?
Temporal bone.
Which cranial bone is inferior to the Temporal bone and protects the brain lobe associated with vision and processing.

What unique bone connected to the axial division does not articulate with other bones and is suspended from styloid processes of the temporal bone (where tongue muscles attach)?
Hyoid bone.
What am I?
Forms the flexible longitudinal axis of the skeleton (the lengthwise axis).
Vertebral column.
What are the characteristics of the vertebrae?
All but the sacrum and coccyx have a vertebral foramen (a hole) where the spinal cord exits and enters.
Second cervical vertebra has an upward projection the dens, allowing head movement.
Seventh cervical vertebra has a long, blunt spinous process.
From top to bottom, what are the names of the curvatures of the spine?
Cervical curvature.
Thoracic curvature.
Lumbar curvature.
Sacral curvature.
What is C1 and C2 vertebra called?
C1 Atlas
C2 Axis
What are the three structures that make up the sternum from top to bottom?
Manubrium
Body
Xiphoid process
What is attached on both sides laterally to the sternum?
Thoracic cage.
What are the three different types of ribs?
True ribs.
False ribs.
Floating ribs.
How many ribs do we have in the body?
12
How many true ribs are there, and why are they named true ribs?
