What are the three types of Connective Tissue?
- A. Connective Tissue Propper
- B. Fluid Connective Tissue
- C. Supporting Connective Tissue
-
What different cell types make Connective Tissue Proper?
- fibroblast
- macrophages
- adipocytes
-
In Connective Tissue Proper what three types of fibers contribute to ECMatrix?
1)Collagen Fibers - Strong flexible,and unbranched.
2)Elastic Fibers - stretchable and branched.
3)Reticular Fibers - thin interwoven and branched
-
Describe the ECF of the Connective Tissue Proper
called ground substance thick like syrup,filling the spaces between the cells and fibers. (prevents bacteria from moving freely)
-
Name and describe the two types of Connective Tissue Proper
- A)Loose Connective Tissue(aka areolar tissue)
- Functions in supporting epithelial&blood vessels, and in protecting organs.
- includes fatty tissue.
- B)Dense Connective Tissue
- strong tissue that functions in supporting bones, muscles, and organs.
- include ligaments and tendons
-
What is Fluid Connective Tissue?
whole blood and ECMaterial (lymph & plasma)
-
What are chondrocytes?
ECMatrix called cartilage
-
What are the three types of cartilage?
- Hyaline cartilage(collagen fibers. ex. ribs& sternum)
- Elastic cartilage(elastic fibers. ex. epiglottis)
- Fibrocartilage(collagen fibers. ex. spinal column and knee)
-
what are the two tpes of bone?
-
-
What is the function of muscle tissue?
to contract, producing movement; voluntary and involuntary
-
What are the three types of muscle tissue?
- skeletal muscle tissue
- cardiac muscle tissue
- smooth muscle tissue
-
Whats the function of the skeletal tissue? (attached tendons)
usually voluntary movement; (partial repair if damaged)
-
What is the function of the Cardiac muscle tissue?
pumping blood through blood vessels, involuntary movement.(little to no repair if damaged)
-
Where are smooth muscle tissue found?
What function does it provide?
- in the walls of blood vessels, and organs.
- functions in bloodflow and digestion, involuntary. (capable of regerating if damaged)
-
What is nervous tissue?
Specialized for conducting electrical impulses (electrochemical) that allows communicating with other cells. Regulates the functions of most organs.
-
Define neurons:
nerve cells that transmit electrical signals throughout the body.
-
Whats the job of the neuroglia?
- support
- supplying nutrients, insulating neurons to assist in the propagation of an electical signal.
-
What are the four membranes?
- muccous membrane
- serouse membrane
- cutaneous membrane
- synovial membrane
-
what are the characteristics of the muccous membrane?
- lines organ systems that are exposed to external environment(digestive, respiratory)
- protects underlying tissues.
- secretes muccous that protects epithelial tissue.
-
What are the characteristics of the serous membrane?
- lines the subcavities of the ventral body cavitiy.
- reduces friction between organs by producing serous fluid.
-
list the characteristics of the cutaneous membrane.
- our skin
- thick, waterproof and dry
-
Where is the synovial membrane located? What is it function?
- at the joints
- secrets synovial fluid to reduce friction
