what are the two main cavities of the body
ventral and dorsal

thoracic and abdominopelvic
the dorsal cavity is subdivided into which two parts
cranial and vertebral canal
the abdominopelvic cavity can be divided into which two parts
abdominal and pelvic
which organs are contained in the thoracic cavity
heart, lungs, trachea, esophagus, large blood vessels, and nerves
which organs are contained in the abdominal cavity
most of the gastrointestinal tract, kidneys, and adrenal glands

most of the urogenital system, and rectum
which organ is found in the cranial cavity
la brain

what type of cell forms bone
osteoblasts
what type of cell breaks down bone
osteoclasts
what are mature bone cells
osteocytes
what do you call a cell that is involved in bones repair and growth
osteogenic cell
what does compact bone consist of
closely packed osteons, also known as haverian systems
what makes up an osteon
a central canal called the osteonic canal, surrounded by concentric rings of, matrix/proteins and molecules that give structure to cells and tissue , with spaces/lacuna in between for osteocytes
what are the small channels that radiate from the lacunae to provide passageway through the matrix into the osteonic canal called
canliculi
