2. TISSUE LEVEL OF
ORGANIZATION
CARTILAGE
-Consists of a dense network of
collagen fibers and elastic fibers
firmly embedded in CHONDROITIN
SULFATE, a gel-like component of the
ground substance; these contribute
to the strength of the tissue
Chondrocytes – cells of the mature
cartilage
3. TISSUE LEVEL OF
ORGANIZATION
Lacunae – spaces which contain
groups of chondrocytes
Perichondrium – covers the surface
of most cartilage
-Cartilage has no blood supply and
heals poorly after an injury
-Three types: HYALINE CARTILAGE,
FIBROCARTILAGE, ELASTIC CARTILAGE
4. TISSUE LEVEL OF
ORGANIZATION
1. Hyaline Cartilage
- Contains a resilient gel as its
ground substance and appears in
the body as bluish-white, shiny
substance
- Mostly surrounded by
perichondrium
- Most abundant cartilage in the
body
- Provides flexibility and support
at the joints
5.
6. TISSUE LEVEL OF
ORGANIZATION
- Reduces friction and absorbs
shock
- The weakest of the three types of
cartilage
2. Fibrocartilage
- Lacks perochondrium
- With a combination of strength
and rigidity, it is the strongest
cartilage
- Found in intervertebral discs
7.
8. TISSUE LEVEL OF
ORGANIZATION
3. Elastic Cartilage
- Provides strength and elasticity
and maintains the shape of
certain structures such as the
nose and the external ear

10. TISSUE LEVEL OF
ORGANIZATION
BONE TISSUE
- classified as compact or spongy,
depending on how its extracellular
matrix and cells are organized.
+ The basic unit of a compact bone
is an OSTEON or HAVERSIAN SYSTEM
+ Spongy bone consists of columns of
bone called TRABECULAE

ORGANIZATION
LIQUID CONNECTIVE TISSUE
1. BLOOD TISSUE (BLOOD)
- is a connective tissue with a
liquid extracellular matrix called
PLASMA (which consists of water and
dissolved substances)
- Formed Elements:
a. Red Blood cells – Oxygen transport
b. White Blood cells - immunity
c. Platelets – blood clotting
14.
15. TISSUE LEVEL OF
ORGANIZATION
2. LYMPH
- flows in lymphatic vessels
- its composition varies from one
part of the body to another
16.
17. TISSUE LEVEL OF
ORGANIZATION
MUSCULAR TISSUE
- consists of elongated cells
called muscle fibers that can use
ATP to generate force
- produces body movement, maintains
posture, generates heat, provides
protection
- 3 types based on structure and
function: SKELETAL, CARDIAC, SMOOTH
18. TISSUE LEVEL OF
ORGANIZATION
1. Skeletal muscle tissue
- Usually attached to the bones of
the skeleton
- Has striations (alternating
light and dark banks within
fibers)
- Voluntary (able to relax and
contract by muscle control)
19.
20. TISSUE LEVEL OF
ORGANIZATION
2. Cardiac muscle tissue
- Forms most of the wall of the
heart
- Has striations (alternating
light and dark banks within
fibers)
- Involuntary (contractions are
not controlled)
21.
22. TISSUE LEVEL OF
ORGANIZATION
3. Smooth muscle tissue
- Located in the walls of hollow
internal structures (intestines,
blood vessels, stomach, etc.)
- Contractions help constrict or
narrow the lumen of blood
vessels, move fluids, move food
- Has no striations or nonstriated
- Involuntary (contractions are
not controlled)
23.
24. TISSUE LEVEL OF
ORGANIZATION
NERVOUS TISSUE
- 2 types:
1. Neuron/Nerve cell
- Sensitive to various stimuli
- Convert stimuli into electrical
signals called action potentials
2. Neuroglia
- Do not conduct nerve impulses
- Functions as support for the
neurons
43. QUESTION:
15. They consist of a
dense network of
collagen fibers and
elastic fibers firmly
embedded in CHONDROITIN
SULFATE, a gel-like
component of the ground
substance
