Growth
my
2
mechanisms 











1.
inters88al
growth‐
expansion
from
within
by
mito8c
division
among
 














chondrocytes
and
addi8on
of
matrix • Up/down/side
to
side
like
ball • In
 inters88al
 growth
 zone
 they
 are 
 collagen
 fibers
 in
 inters88al 
 matrix
 but
 they
 are
 imbedded
in
the
gel
like
substance • Elas8c
fibers
are
also
here
hair
like
and
permeate
through 











2.
Apposi8onal
growth‐
new
cells
and
matrix
form
along
surface
of
car8lage
 















Grows
like
hair
would
from
follicle 



Found
in
 











1.
joint
surface
of
bone 











2.
ventral
ends
of
ribs 











3.
tracheal
rings
and
larynx • When
2
or
more
seen
in
1
lacuna
its
isogenic
group
and
is
temporary.
They
are
undergoing
mitosis B.
Elas8c
car8lage 





1.
more
flexable
but
also
suppor8ve 





2.
found
in
“e”places • External
ear • EpigloZs • Eustachian
tube
walls • Eu‐nose C.
Fibrocar8lage
:
xmas
slide 





1.
collagen
fibers
almost
cover
chondrocytes 





2.transi8onal
8ssue
between
car8lage
and
CT
proper
chondrocytes
are
found
in
lacunae
but
 









are
not
visible
and
no
apposi8onal
growth
seen
because
bones
limits
growth. 





3.
found
in
where
weight
bearing
is
nessasary • Pubic
symphysis • Ivd’s • Sites
of
a]achment
of
tendons
to
bone Tissue
type Blood 1.Erythrocyte
(RBC’s) ‐gas
transport 

2.
Leukocytes
(WBC’S) 










Granular 











a.
neutrophils‐
3‐5
lobes
in
mature
state
connected
by
thin
stand
chroma8n
material 











b.
eosinophils‐
large
cytoplasmic
granules‐
bi
lobed 











c.
basophils‐
look
like
raspberry
metachroma8c
granules 









Non‐granular 











a.
monocytes‐
nuclear
region
2
½
8mes
larger
than
an
eurthrocyte
shape
is
kidney
bean
 
















*largest
of
all
WBC* 











b.
lymphocytes‐
smallest
of
all
WBC‐
nuclear
region
will
be
larger
than
RBC 

















shape
is
crescent
shape
or
thin 3.
Platelets
≠
Thrombocytes • From
megakaryocyte‐only
found
in
bone
marrow.
Its
cytoplasmic
region
break
off
(fragments)
 and
makes
a
platelet.
Func8on
is
blood
cloZng • Cytoplasmic
fragments=humans • Thrombocytes=birds
and
rep8les They
do
the
same
thing
essen8ally
but
thrombocytes
are
an
whole
cell.
