What are the characteristics of CT
|
1. Cells not in contact with each other
2. Many types of cells can live in CT |
|
|
In CT, what are the cells surrounded by
|
Extracellular Matrix or ECM
|
|
|
What does the ECM contain
|
collagen fibers
elastic fibers reticular fibers and ground substance>proteins, carbohydrates, water, other molecules |
|
|
Tough protein fiber with tensile strength
|
Collagen
|
|
|
Flexible protein fiber
|
elastic fiber
|
|
|
Protein fiber that is weved together to make a meshlike framework
|
Reticular fibers
|
|
|
Name the functions of CT
|
1. protection
2. physical framework 3. connect things together 4. transport |
|
|
What are the three types of Connective Tissue
|
1. Proper
2. Support 3. Fluid |
|
|
What are the two types of CT Proper?
|
1. Loose
2. Dense |
|
|
Type of CT proper found in many places, especially packing organs and cushioning
|
Loose CT
CT>proper>Loose or dense |
|
|
What are the three types of Loose CT?
|
1. areolor
2. adipose 3. reticular |
|
|
This type of loose CT cells are fibroblasts, in a viscous ECM,and found in subcutaneous layer (under skin) and around many organs
|
areolar
CT>Proper>loose>areolar or adipose or reticular |
|
|
Cells that make and secrete lots of fibrous proteins
|
Fibroblasts
|
|
|
This type of CT is made up of cells that are adipocytes, in a loosely packed ECM
|
CT>Proper>loose>adipose
|
|
|
This type of CT is made of cells called fibroblasts and found in tougher ECM. It forms the stroma or framework of organs like liver and spleen
|
CT>Proper>loose>Reticular
|
|
|
What mades CT>proper>dense so dense
|
More proteins makes the ECM dense
|
|
|
This type of tissue has fibroblast cells and found in densely packed ECM of collagen fibers. Handles stress really well in one direction because fibers are parallel.
|
CT>Proper>dense>regular
|
|
|
This type of CT is made of fibroblast in a densely packed but irregular array of mostly collagen fibers. Has strength in all directions
|
CT>Proper>dense>irregular
|
|
|
This type of CT has mostly cells that are fibroblasts, in an ECM of mostly elastic fibers. It can stretch and return to original shape
|
CT>Proper>dense>elastic
|
|
|
What is thwo types CT>Supporting
|
Cartilage
Bone |
|
|
Firm, almost rubbery
avascular cells called chondroycytes cells in spaced called lacuna |
CT>cartilage
|
|
|
Weakest type of cartilage, glassy appearance, wrapped in perichondrium. Some examples supports nose and trachea. conncects some ribs to sternum. Covers end of long bones
|
CT>supporting>cartilage>
hyaline |
|
|
This type of CT is very durable, has no perichardium, acts as a shock absorber in intervertebral discs,pubic symphysis, and knee joints
|
CT>Supporting>cartilage>fibrocartilage
|
|
|
This type of CT is flexible and resilient. Has perichondrium. Examples are epiglottis and external ear
|
CT>Support>cartilage>elastic
|
|
|
This is a type of CT that is also an organ
|
CT>Support>Bone
