1. TO BONES!

2. Using Your Head for the
• Holidays bones (form a
The skull is composed of cranial
vault for the brain) and facial bones (giving origin to
the muscles of facial expression and providing
buttresses protecting the brain). Except for the
temporomandibular joint (a synovial joint), all
bones are connected by generally immovable
fibrous sutures.
• The orbit is composed of seven bones, has three
significant fissures/canals, and is home to the eye
and related muscles, nerves, and vessels. The
most delicate of the skull bones is at the medial
orbital wall. The external nose is largely
cartilaginous and is therefore not part of the bony

7. What would your
tongue do without
your Hyoid on
Thanksgiving
Day?!
The hyoid a U-shaped bone at the
base of the tongue that supports the
tongue muscles.

8. The Spinal Column
Sit up straight when
eating at the table! Use
your BACK BONES!

9. The Sternum and Ribs
There are 24 ribs total in the
human body. There are 6 true
ribs on both sides of rib cage
(12 total). They are called true
ribs because directly connect
to the sternum. There are also
6 false ribs on each side of the
rib cage (12 total) which
consist of the 2 pairs of
floating ribs. They are called
false ribs because the do not
directly connect to the
sternum as shown in the
diagram. The floating ribs got
their name because they do
not connect to the sternum but
they do connect on the spine.
It looks like they are floating
because they are not
connected to the front of body.

17. The Lower Extremities
The acetabulum is a concave surface of the pelvis.
The head of the femur meets with the pelvis at the
acetabulum, forming the hip joint. With maturity,
the ilium, ischium, and pubis meet and grow
together at a Y-shaped junction, the site of the
acetabulum, a deep cavity that receives the
rounded head of the thighbone, or femur.
Male or Female?
To find the difference between a male or female
skeleton lies within the bones. A skeleton's overall
size and sturdiness give some clues. Within the
same population, males tend to have larger, more
robust bones and joint surfaces, and more bone
development at muscle attachment sites. However
the best way to find out is by the pelvis, because of
distinct features adapted for childbearing.
