System - Bone Directory
The Bone Directory provides a
brief description of the characteristics of
certain bones in the body. Bones are listed in
- Carpals are bones that make
up the wrist joint. There are eight carpal
bones in each wrist. These bones are small and
glide against each other so that we can move
our wrist in different directions.
- This bone is more commonly
known as the collarbone. The clavicle connects
with the scapula and the sternum. The clavicle
is the most frequently broken bone in the
- Cranium (say:
- The cranium is the part of
the skull that protects the brain. The cranium
is the upper part of the skull without the
- Femur (say: fee-mur)
- Largest bone in the body.
More commonly known as the thigh bone. The
femur is the longest, strongest, and heaviest
bone in the body. The femur supports much of
our body weight.
- Fibula (say:
- This long thin pin-like
bone is found on the outside of the tibia. The
fibula's main job is to provide sites for
muscles to attach. It also acts as a brace and
provides support for the tibia. The fibula is
located in the lower leg.
- Humerus (say:
- More commonly known as the
"funny bone." The humerus is the largest bone
in the upper limb (arm). Its smooth, ball-like
head fits into the scapula and forms our "ball
and socket" shoulder joint.
- This is a U-shaped bone and
forms the lower jaw. It is the largest and
strongest bone in our face. The mandible is
the movable part of the skull.
- Metacarpals are bones of
the hand. Press on the back of your hand and
you can feel your metacarpals. Make a fist and
look at your knuckles. Your knuckles are the
ends of your metacarpals.
- Metatarsals are bones of
the foot. There are five metatarsals.
- Touch your kneecap. Your
kneecap is the patella. The patella is a round
- Your pelvis is your hip
bones. Elvis Presley was famous for shaking
his hips when he danced and he was nicknamed
"Elvis the Pelvis."
- Phalanges (say:
- Phalanges are better known
as your fingers and toes. You have 14 phalange
bones in each hand and 14 in each foot, for a
GRAND TOTAL of... 56 phalanges!
- Radius (say:
- This is one of the two
forearm bones. The forearm is the lower part
of your arm from your wrist to your elbow. The
radius is thinner near the elbow and gets
thicker with a bulge near the wrist.
- You have twelve pairs of
ribs. In the front of your body they attach to
your sternum with flexible cartilage. In the
back of your body they connect with the
vertebrae. Your ribs are a bony cage that
protects your heart and lungs.
- Scapula (say:
- This thin, flattened,
triangular bone is found on the back of the
shoulder area. The scapula connects the
clavicle to the humerus. The scapula is
commonly called the "shoulder blade."
- Sternum (say:
- More commonly known as the
"breastbone." Located right in the middle of
- These are the bones in your
ankle. There are seven tarsal bones that allow
for movement in the foot.
- Tibia (say:
- This bone is also known as
the shinbone. The tibia is the second largest
bone in the skeleton and is found in the lower
leg. The Tibia is very large at the top where
it connects with the femur at the knee joint.
- Ulna (say: ul-nuh)
- The ulna is a long thin
bone of the forearm. The top "wrench-like" end
of the ulna is larger that the small, rounded
end. It is next to the radius in the lower
- Vertebrae (say:
- The vertebrae are the bones
of the spine. There are 26 vertebrae. The top
one is the atlas and the bottom one is the
coccyx (say: cok-sicks). The vertebrae protect
the spinal cord.
