Anatomy Exam 4
keratinocytes correct answers make vitamin D in
the skin
long bone correct answers bone with cylindrical shape that are longer
than they
wide; don'tare
have to be big; serve as rigid levers that are acted upon by
skeletal
to produce muscles
the major body
movements
short bone correct answers short in
length
flat bone correct answers flat in one dimension; some bones in skull; some
are longer
than they are
wide
Irregular bone correct answers bones that don't fit any category;
sphenoid bone
compact bone correct answers form outer shell of long bone; arranged
in lamellae;
lamellae surrounding one central canal in bone (where blood vessels pass
through);
osteocytes are connected by canaliculi; osteons with its central canal
and lamellae
spongy bone correct answers little blood vessels in open spaces; no
central
cells of canals;
bone in ring structures not around central canal; lamellae are not
all parallel =has osteocytes in lacunae and canaliculi between; covered with
trabeculae;
endosteum
and permeated by spaced filled with bone
marrow
medullary cavity or marrow cavity correct answers where bone marrow is
in the
red bone;
bone marrow in spongy bones and yellow bone marrow in long
bones (mostly
adipose
tissue)
diaphysis correct answers shaft of long
bone
epiphysis correct answers each end of the
long bone
epiphyseal plate correct answers serves as growth center while
bone replaces
cartilage; continuously growing as a child and cartilage is being
continuously
by new bone replaced
tissue
epiphyseal line correct answers plate of compact bone separating spongy
bone
the from
diaphysis region and the
epiphysis
periosteum correct answers tightly held by fibers of fibrous layer;
blood vessels
penetrate the bone and nerves surround the bone collecting sensory
information;
muscles where
are attached to the bone for
movement
, perforating fibers correct answers outermost layer of periosteum that is
usually dense
irregular with some collagen fibers that go down to the matrix of the bone
anchoring the
periosteum to the surface of the bone
tissue
endosteum correct answers membrane connective tissue structure inside;
in between
yellow bone marrow and trabeculae; covers all of trabeculae and
extendsof
interior allcanals;
along has osteoclasts and
osteoblasts
hydroxyapatite correct answers crystallized calcium phosphate salt;
makes up matter
inorganic most in the bone matrix; enables bone to support the weight
of the body
without
sagging
collagen correct answers organic matter synthesized by
osteoblasts
skeletal system correct answers bones and cartilage structures associated
with bones
make this
up
particular bone correct answers single bone described as an organ
with multiple
tissues; most mass is bone tissue but will have connective tissue layers
around
bone the and outer tissue types inside
tissue
the mass
supporting internal structure and giving us shape; could not move in
environment
without the internal stiff structure in order to move muscles that pull
bones;
jobs; protective
reserve of calcium and phosphorous; regulation of taking in or out
calcium
bones of our
when needed correct answers What are the functions
of bones?
calcium phosphate salts correct answers Why is the
matrix hard?
lacunae correct answers mature bone cells live here after they cause the
deposition
the of
hard hydroxyapatite wrapping around
themselves
access to calcium and phosphate correct answers What do cells
need for
hydroxyapatit
e?
calcium absorption correct answers only works when gut is stimulated by
a chemical
signal by calcitriol made by
vitamin D
rickets correct answers lack of calcium that will lead to bone weakening
from a lack of where the bones become
hydroxyapatite
deformed in kids
long bone correct answers cylindrical shape and are longer than they are
wide; to
have don't
be big and can be
small
short bone correct answers cylindrical and wider than they
are longer
flat bone correct answers flat; present in skull and some are longer than
they are wide
