Download I. Proper Connective Connective Tissues:

C.T. Introduction:
Connective Tissues:
General
Characteristics and
Types
• Most abundant tissue in the body
• Composition of Intercellular materials
determines tissue qualities (From Blood
to Bone)
General Characteristics of C.T.
• Vascular - rich blood supply
• Widely scattered cells - large
amountt off matrix
t i material
t i l
• Not found on a free surface sandwiched between other tissues
I. Proper
Connective
Tissues:
(Has primarily a fluid
matrix)
1. Loose Connective
Tissue, Areolar
• most widely distributed
• Location: Combines with Adipose Tissue to
form subcutaneous layer (attaches skin to
underlying tissues), in all mucus membranes,
around blood vessels, around body organs
• Function: Wrap & cushion organs, assist in the
inflammatory response – holding and moving
tissue fluids
2. Loose Connective Tissue,
Adipose (Fat)
• Location: Accompanies Areolar C.T. &
found in subcutaneous layer, and in
yellow
ll bone
b
marrow
• Function: Serves as an energy reserve,
supports & protects organs, reduces heat
loss through skin

3. Loose Connective Tissue,
Reticular
• Location: makes up liver, spleen,
lymph nodes
• Function: Provides framework w/in
organ tissue
4. Dense Connective Tissue, Dense
Regular
• Location: tendons, ligaments,
aponeuroses (sheath enclosing muscle)
• Function: Provides strong attachment
between muscle and bone – withstand
stress when pulling force is applied in one
direction
5. Dense Connective Tissue,
Dense Irregular
• Location: periosteum (outer membrane of
bone), joint capsules, heart valves, dermis
off the
th skin
ki
• Function: Provides strength, withstand
stress from many directions
A. Hyaline (Gristle) - Most
Abundant
• Location: covering the ends of long
bones (articular cartilage), ventral
ends of ribs (costal cartilage),
cartilage) nose,
nose
trachea, bronchi
• Function: Support, Flexibility and
Reduce Friction in joints
II Cartilages
II.
(Primary cell Chondrocyte)
B. Fibrocartilage • Location: symphysis pubis,
intervertebral discs
• Function: Strength, Rigidity, &
Support - Binds one structure to
another
2
C. Elastic Cartilage • Location: larynx (voice box),
external ear
• Function: Flexibility, maintains
shape
III. Other Connective Tissue
• Bone(s) - Osseous Tissue (Primary cell
osteocyte)
• Blood
• Hemopoietic - (Red Bone Marrow)
• Lymphatic Structures
