Question	Answer
functions of the skeletal system	support, storage of minerals and lipids, blood cell production, protection, and leverage
storage in lipids that represent an important energy reserve in bone occur in areas of:	yellow marrow
mature bone cells found in lacunae	osteocytes
giant multinucleated cells involced in the process of osteolysis	osteoclasts
one of the basic histological differences between compact and spongy bone is that in compact bone the	basic functional unit is the Haversian System
spongy/ancellous bone, unlike compact bone, resembles a network of bony struts separated by spaces that are normally filled with:	bone marrow
spongy bone is found primarily at the	expanded ends of long bones, where they articulate with other skeletal elements
compact bone is usually found where	when stresses arrive from a LIMITED range of directions
during intramembranous ossification the developing bone grows outward from the ossification center in small struts called:	spicules
when osteoblasts begin to differentiate with a connective tissue, the porcess is called:	intramembranous ossification
the process during with the bones begin developmentas cartilage models and the cartilage is later replaced by bone is called:	endochondral ossification
the metaphysis is the area where	cartilage is being replaced by bone
the bony skeleton begins to form about _______ after fertilization, and usually does not stop growing until about age___	6 weeks; 25
the process of replacing other tissues with bone is called	ossification
as one osteon forms through the activity of osteoblasts, another is destroyed by osteoclasts is:	homeostatic mechanism
the condition that produces a reduction in bone mass sufficient to compromise normal function:	osteoporosis
the major effect that exercise has on bones is:	it serves to maintain and increase bone mass
growth hormone from the pituitary gland and throxine from the thyroid gland maintain normal bone growth activity at theL	epiphyseal plates
a fracture that only one side of the shaft is broken and the other side is bent	greenstick
a pott's fracture is identified primarily by:	dislocation
a fracture that occurs at the ankle and the ankle and affects both bones of the lower leg	pott's fracture
long bone	humerus
bones forming at the roof of the skull and the scapula are referred to as:	irregular bones
storage of lipids in bones occurs in the	yellow marrow
of the 5 functions of the skeleton, the 2 that depend on the dynamic nature of bone are	storage and support
cuboidal cells that synthesize the organic components of the bone matrix are	osteoblasts
in adults, the cells responsible for maintaining the matrix in osseous tissue are the	osteocytes
the basic functional unit of compact bone is the:	osteon
the expanded region of a long bone consisting of spongy bone is called:	the epiphysis
what is the process when when osteoblasts differentiate within the a mesenchymal or fibrous connective tissue	intramembranous ossification
the type of ossification that begins with the formation of a hyaline cartilage odel is	endochondral
the process which refers specifically to the formatino of bone is	ossification
the major mineral associated with the development and mineralization of bone is	calcium
the organic and mineral components of the bone matrix are continually being recycled and renewed through the process of	remodeling
the ability of bones to adapt to new stresses results fro the turnover of recycling of	minerals
the hormone synthesezed in the kidneys which is essential for normal calcium and phosphate ion absorption in the digestive tract is	calcitriol
fractures which shatter the affected area into a multitude of bony fragments are	communited fractures
fractures which project through the skin are called	compound fractures
bones which have complex shapes with short, flat, notched, or ridged surfaces are termed	irregular
sutural bones which are small, flat, odd-shaped bones found between the flat bones of the skull are referred to as	wormian bones

humerus*	long bone
fracture that moves in a spinning motion	spiral
fracture that protrudes through the skin	open fracture
shattered fracture	communited
fracture to the head; dented in	depressed
osteoblasts within connective tissue secrete	collagen
osteoblasts within connecttive tissue become trapped to become	osteocytes
spicules (trabeculae) grow into	spongy bone
osteocytes occupy	lacunae
lacunae are found in	spongy bone and compact bone
perichondrion becomes	periosteum
periosteum produces	osteoblasts
what is parathormone released by?	parathyroid
thryoid releases	calcitonin
calcitonin causes	a decrease in intestinal absorption of Ca
a decrease in intestinal absorption of Ca results in	a decrease in calcium level

what are located between the layers of the arm?	osteocytes
small channels that the bone cells communicate in	canaliculi
disk-shaped cells	red blood cells
a large canal located at a right angle to the bone's shaft; also the major communicating pathway between the bone's interior and exterior surface	Volkman's Canal
dense tissue surrounding a canal	compact bone
a largetube-like canal that runs parallel to the long axis of the bone	Haversian Canal
a largetube-like canal that runs parallel to the long axis of the bone	Haversian Canal
also known as nerves	blood vessels
also known as nerves	blood vessels
