The parietal bones meet the occipital bone along the _________ suture.
Lamboid suture
100
The fat inside the medullary cavity is called...
Yellow marrow

What is the difference between osteoblasts, osteoclasts, and osteocytes?
Osteoblasts are cells that secrete calcium to build up bone.
Osteoclasts break down bones that are damaged so their materials can be resorbed.
Osteocytes are bone cells that exist within compact bone in little pockets called Lacunae.
100
What are the functions of the skeleton?
formation of blood cells
protect organs
storage of salts and fat
movement
100
What is osteoporosis and what does it cause?
A genetic disease where your osteoclasts are more active than your osteoblasts. This causes bone degeneration and causes brittle, fragile bones.
100
Label structures... 
E: Canaliculae
AB: Lacunae
D: Osteocyte
200
The proximal epiphysis of the femur is closest to which other bone?
a: patella
b: coccyx
c: sacrum
d: tibia
coccyx
200
what is the function of red marrow
to produce red blood cells.
200
the tough membrane covering the outside of the bone is..
the periosteum
200
This disorder causes bones to form in places where there is normally soft tissue. This causes a loss of mobility over time:
fibrodysplasia ossificans progressiva (FOB)
200
the soft spots of an infants skull are known as
fontanels
200
What structures are labeled A, AC, and B? 
A: Lamellae
AC: Volkman's Canal
B: Haversian canal
300
what is the largest of the tarsal bones called?
the calcaneous
300
The presence of an epiphyseal disk vs line indicates that...
Bones are still forming (getting longer). When the disk gets replaced by real bone, not cartilage, the disk turns into a "line."
300
The purpose of the articular cartilage is to...
Cushion the ends of bones.
300
Between what two bones would you find a pivot joint?
radius and ulna
300
The process of hematopoesis results in?
production of red blood cells
300
Label ONLY A, B, C, D, and E
A: Frontal . B: parietal . C: Temportal . D: Occipital . E: coronal Suture

The clavicles and the scapulas make up the:
pectoral girdle
400
the hard middle shaft of the bones are called what?
Diaphysis
400
the membrane that lines the interior of the medullary cavity is the...
endosteum
400
Freely movable joints, such as those of the knee or elbow are called what?
Diarthrotic joints
400
the two large bones that make up the hip (pelvis) are called the...

In your neck, under your jaw bone, is a U-shaped bone called the:
Hyoid bone
500
what is the difference between lacuna and lamellae?
Lacunae are the little pockets that osteocytes (bone cells) rest in.
Lamellae are the concentric rings that make up compact bones.

a fracture where the bone breaks through the skin is called...
an open break

foramen magnum
