Connective chart – Alex Chavez AMY 2A F’2014
Loose Connective Tissue Proper
Tissue
Areolar
Adipose
Reticular
Characteristics
Cells
- Gel-like matrix
- Composed of 3
fibers
- Loose
arrangement
- H-acid
-Sparse gel like
matrix
- Nucleus off to side
because of tight
packaging
- Network of fibers
in typical loose
ground substance.
- Never alone;
always look for
cells, vessels
Fibroblasts/cytes;
macrophages;
mast cells; wbcs
- Adipocytes
- Fibroblasts
(reticular cells)
Location
-Under epithelia (L.P
of mucous
membranes)
- Packaging organs
- Surrounds
capillaries
- Reserve food fuel
- Insulation to
prevent heat loss
- Supports and
protects organs
- Marrow, sleen,
nodes (lymph)
Function
- Wraps/cushions organs
- Inflammation
- Hold and conveys tissue fluid
- Macrophages
- Connects tissue to tissue
- Most widely dist. In body
- Hypodermis
- Kidneys; eyeballs;
breasts;
within abdomen
- Bones
- Stroma: soft internal skeleton
that
supports Wbcs, mast cells, &
macrophages
Dense Connective Tissue Proper (Fibrous)
- Fibroblasts
Dense Regular
- Parallel collagen
fibers
- Few elastin fibers
- White
- Poorly
vascularized
1) Tendons
2) Ligaments
3) Aponeuroses
1) Muscle to bone
2) Bone to bone
3) muscle to muscle
- Tensile strength in 1 direction
- Fibroblasts
Dense Irregular
- Irregularly
arranged collagen
fibers
- Some elastic fibers
- Thicker than d.
regular
- Dense connective
w/ elastic fibers
Elastic
- Dermis
- Submucosa
digestive tract
- fibrous capsules of
Kidneys, bones,
cartilages, muscles
and nerves (joints).
- Ligaments in
vertebrae (l. nuchae)
- Within walls of
bronchial tubes
- Walls of large
arteries
- Withstands tension in many
directions
- Tensile strength
- Tensile strength + moderate
elasticity

Cartilage:
-Lacks nerves; is avascular; obtains nutrients via diffusion from blood vessels; Ground substance : GAGs chondroitin sulfate
and hyaluronic acid, firmly bound collagen fibers. Lacunae: cavities that house small groups of chondrocytes
Tissue
Hyaline
Elastic
Fibrocartilage
Bone (tissue)
Blood
Characteristics
Cells
Location
Function
- Most abundant
- Glassy, blue-white
- Firm matrix
- Collagen fibers
- Chondroblasts
- Chondrocytes
- Embryonic skeleton
- Tip of nose
- Rib to sternum
connection
- Resp. passages
Epiphyseal plates: regions near
ends of long bones.
Articular: Provides cushion at
covers of long bones.
- Resists compressive stress;
cushions.
- Support and reinforce
- Structure + flexbility
- More elastic fibers
than Hyaline
- Less firm than
hyaline
- Thick collagen
fibers
- Intermediate to
hyaline and Dense
regular (rows of
chondrocytes alt.
w/rows of thick
collagen fibers)
- Hard, calcified
matrix
- Many collagen
fibers
- Inorganic calcium
- Highly vascular
- Chondroblasts
- Chondrocytes
- Chondroblasts
- Chondrocytes
- External ear (pinna)
- Epiglottis
- Intervertebral discs
- Pubic symphysis
- Knee joint
- Osteocytes
(lacunae)
- Osteoblasts
-
- Bones
- Enclosure provides support
and protection
- Levers for muscles
- Storage: calcium, fat, minerals
- Hematopoiesis: rbc production
- Most atypical
- Does not provide
support or
connection
- Blood cells and
plasma
- Erythroctyes
- White blood cells
- Platelets
- Within blood
vessels
- Transport vehicle for
cardiovascular system
- Nutrients, wastes, respiratory
gases
- Tensile strength + ability to
absorb compressive shock
