Left and right mid clavicular, subcostal line, and intertubercular line
What are the 9 regions when abdomen divided with 4 lines
R and L hypochondriac, epigastric, R and L lumbar, umbilical, R and L iliac and hypogastric
What are the four types of tissues
Epithelial, muscular, nervous and connective
Function of skeletal system
Support, protection, assistance in movement, mineral storage and release, blood cell production, triglyceride storage in yellow bone marrow
Diaphysis
Shaft or body
Epiphysis
Distal and proximal end of bones
Metaphysis
Tapered area where the diaphysis joins the epiphysis
Articular cartilage
A thin layer of cartilage that covers the epiphysis
Periosteum
Coating on bone surface
Endosteum
Covers inside of bone lining
Medullary cavity
Filled with either red or yellow bone marrow
What is compact bone
External layer of bone
Compact bone forms most of what
Diaphysis of long bones
Function of compact bone
Protection, support and resists the stresses produced by weight and movement
Compact bone tissue is arranged in units called
Osteons
Osteons are also known as
Haversion systems
Spongy bone also known as
Cancellous or trabecular bone
Structure of spongy bone
Consists of lamellae that are arranged in an irregular lattice called trabeculae and inbetween them are filled with red or yellow marrow
Where are spongy bones found
Core of short, flat and irregular shaped bones and most of the epiphysis of long bones and a narrow rim around medullary cavity of diaphysis
What are the types of cells in the bone
Osteoprogenitor, osteoblast, osteocyte, osteoclast
Function of osteoprogenitor cell
Develops into osteoblast
Function of osteoblast
Forms bone extracellular matrix
Function of osteocyte
Maintains bone tissue
Function of osteoclast
Resorption, breakdown of bone extracellular matrix
What are the different bone shapes
Long, short, flat, irregular, sesamoid, and sutural
What are some bone features for depressions and openings

Fissure
Narrow slit between adjacent bony parts
Foramen
Opening for blood vessels and nerves
Fossa
Shallow depression
Sulcus
Furrow or fissure
Meatus
