Slide1
Common Characteristics of Connective Tissue
Most
common
Well
supplied with blood
.
(tendons and ligaments)
Made
up of
many types of cells and
extracellular matrix
Slide2
Extracellular matrix
Produced by the connective tissue
cells
then
secreted to the exterior
Can be liquid, gel-like, or solid
Examples:
Fat tissue:
mostly
cells and a soft matrix
Bone:
few cells
and
very hard matrixSlide3
Types of connective tissue
5 different types:
Bone
Cartilage
Dense connective tissue
Loose connective tissue
BloodSlide4
1. Bone
Bone cells (
osteocytes
) sitting in cavities surrounded
by
a very hard ECM
Protect and support other body organsSlide5
2. Cartilage
Softer
and
more flexible
than bone
cells
with a rubbery ECM
Functions to
absorb impact to the bone
or
form structures where elasticity is desiredEx: the ear and between vertebrae, ribsSlide6
3. Dense Connective Tissue
Contains
fibroblast cells with
tough
fibers
as the ECM
Forms strong ropelike structures
Tendons, ligaments, dermisSlide7
Tendons and Ligaments
Tendons:
attach skeletal
muscles to bones
Less stretchy and contain less elastic fibers
Ligaments
:
connect
bones to bones
at jointsMore stretchy and contains more elastic fibersSlide8
4. Loose Connective Tissue
Softer and have more cells and fewer fibers in ECM
2 main types:
Areolar
AdiposeSlide9
Areolar Tissue
Most
widely distributed
connective tissue
Has several important
functions
1.
Universal packing tissue
because it wraps
around organs as protection 2. Hold organs in their proper positionsSlide10
Adipose Tissue
AKA
fat
Forms
beneath
the skin
Protects the body from
temperatures and provides some protection to organsSlide11
5. Blood
Considered connective tissue because it is
composed of blood cells surrounded by a fluid ECM called blood plasma
Transport nutrients, wastes, and respiratory gases.
