SKELETON SYSTEM CONSIST OF

BONES,JOINTS,CARTILAGE,LIGAMENTS

WHATS THE FUNCTION OF SKELETAL SYSTEM

IT SUPPORTS THE WEIGHT OF BODY,THE SOFT BODY ORGANS,ENABLES BODY TO MOVE,STORES MINERALS, CALCIUM AND PHOSPHOROUS.

WHAT PRODUCES BLOOD CELLS

RED BONE MARROW

LONG BONES

LONGER THEN THEY ARE WIDE

SHORT BONES

SHAPED LIKE CUBES ARE FOUND PRIMARILY IN THE WRIST AND ANKLES

FLAT BONES

FLAT CURVE , FORM RIBS BREATS BONE AND SKULL

IRREGULAR BONES

DIFFERENTLY SHAPED, NOT CLASSIFIED LONG, SHORT OR FLAT, INCLUDE HIP BONES, VERTABRAE AND VARIOUS BONES IN SKULL

WHATS ANOTHER WORD FOR BONE

OSSEUS TISSUE

OSTEOCYTE

BONE CELLS

SCRETE INTRACELLULAR MATRIX

CONTAIN CALCIUM,MINERALS,AND PROTEIN FIBERS

WHAT IS SPONGEY BONE ALSO CALLED

CANCELLOUS

WHAT ARE TWO TYPES OF BONE

COMPACT BONE-DENSE AND HARD FOUND IN SHAFTS AND SURFACE OF OTHER BONES

SPONGY BONE LESS DENSE FOUND IN THE END OF LONG BONES ITS IN THE CENTER OF OTHER BONES

WHAT IS TIGHTLY PACKED, DENSITY GIVES IT STRENGTH

COMPACT BONE

OSTEON OR HARVERSION

SYSTEM IN MICROSCOPIC UNIT OF COMPACT BONE

WHAT DOES EACH OSTEON HARVERSION SYSTEM CONTAIN

THEY CONSIST OF MATURE OSTEOCYTES ARRANGED IN CONCENTRIC CIRCLES AROUND LARGE BLOOD VESSELS

LONG BONE

CONTAINS SITES OF GROWTH AND RESHAPING AND STRUCTURES ASSOCIATED WITH JOINTS

WHATS AT THE MIDDLE OF LONG BONE

MIDDLE DIAPHYSIS

WHATS AT THE END OF EACH LONG BONE?

EPIPHYSIS

WHAT SUPPLIES THE SPONGEY BONE WITH BLOOD CELLS

RED BONE MARROW USED THROUGH OUT THE BODY

SPONGY BONE ALSO CALLED CANCELLOUS BONE

DOES NOT HAVE HAVERSIAN CANAL

THE AREA AROUND COMPACT BONE

ITS FILLED WITH OSTEOCYTES FILLED WITH PROTEIN FIBERS CALCIUM AND OTHER MINERAL

What do osteoblast do

secret calcium and minerals into spaces between the membrane there by forming bone

what happens with ossification of long bones

bone tissue replaces cartilage

what does osteoblast do

secrete calcium and other minerals into the spaces between the membranes there by forming bone

what is ossification

formation of bone

Articular cartilage does what

its on outer surface of epiphysis , forms a smooth shiny surface it decrease friction within a joint

What happens if you have an injury in peristoneum of long bone

major consequences due to the fact it carries our blood supply

What does periosteum do

protects bone serves as a point of attachment for muscle

what is periosteum

tough fibrous tissues that that covers the outside of diaphysis

medullary cavity

hollow center of the diaphysis the inside is line with connective tissue called endosteum

Epiphyseal disc

band of hyaline, located at each end of long bone epiphysis and diaphysis this is where growth plate is

what is articulation

where two bones meets

WHAT IS EPIPHYSIS COVERED IN

CARTILAGE as well as a thin layer of compact bone

WHAT DOES THE DIAPHYSIS DO IN LONG BONE

IT PROVIDES STRENGTH AND IS PRIMARILY OF COMPACT BONE

sinus

A cavity or hollow space

meatus

tunnel or tube like

foramen

opening in the whole

Trochantor

large tuberosity found only on the femur

facet

small flattened surface

head

an enlarged and rounded end of a bone

what get messed up when you break a hip

the femoral neck

condyle

large rounded knob that usually articulates with another bone

what does exercise and weight barring do

keep calcium in the bone and increase bone mass

what does weight bearing do?

factors that stimulates bone growth

bone resorption

widens bone, moves calcium from bone to blood , plays a crucial role in blood calcium levels

longituadinal growth

ceases after puberty

epiphyseal disc

more sensitive to estrogen this causes girls to be shorter then boys

estrogen and testosterone

cause the epiphyseal disc to fuse inhibiting further longitudal growth

growth hormone

stimulates growth

longitudinal bone

growth cease when epiphyseal disc becomes ossified and fused

as long as cartilage continues to form within

The epiphyseal disc the bone will continue to lengthen

what are two types of bone growth occurs from infancy to adulthood

longitudinally height of individual

thicker and wider to support weight of the adult

what happens as baby matures

osteoblast invade the cartilage and gradually replace it with bone untill all but articular cartilage and the epiphyseal disc have been replaced by bone

ossification of long bone

when bone tissue replaces cartilage

the fetal skeleton

composed largely of cartilage
