Connective Tissue 2 Block 1 Flashcards
What are the three classifications of connective tissue
Connective tissue proper
Fluid connective tissue
Supportive connective tissue
What takes up the majority of the cell volume
The matrix
Fluid ct does what
Transports
Supportive ct does what
Structural strength
T proper does what
Connects and protects
Example of loose ct
Adipose
Example of dense ct
Tendons
Which tissue has more ground substance and less fibers
Loose ct
Which tissue had kiss ground substandard and more fibers
Dense ct
8 types of ct cells?
Fibroblast
Macrophages
Adipocytes
Mesenchymal cells
Melanocytes
Mast cells
Lymphocytes
Microphages
What is the most abundant cell type in ct
Fibroblast
Fibroblast secrete what two things
Proteins and hyaluronan
What cells are large, amoeba like cells of the immune system
Macrophages
What do macrophages do
Eat pathogens and damage cells
Which macrophages stay in tissue
Fixed macrophages
Which macrophages migrate
Free macrophages
What are fat cells called
Adipocytes
Each adipocyte stores what
One large fat cell
Mesenchymal cells are?
Stem cells
What cells respond to injury or infections
Stem cells
What cell synthesizes and stores the brown pigment melanin
Melanocytes
What cell stimulates inflammation
Mast cells
Which cell release heparin and histamine in a response to inflammation
Mast cells
What is the name for mast cells that are carried by blood
Basophils
What are lymphocytes
These are specialized immune cells in the lymphatic system
What is an example of a lymphocyte
Plasma cell- produces antibodies
What are known as phagocitic blood cells
Macrophages
What do macrophages respond to
Signals from macrophages and mast cells
Two examples of microphages
Neutrophils and eosinophils
What fiber is long straight and in ranches
Collagen fiber
Which fiber only resists force in one direction
Collagen fiber
Which fiber resist force in many directions
Reticular fibers
Which fiber stabilizes function cells (parenchyma) and structures
Reticular fiber
What does elastic fiber do after stretching
It returns to its original length
What fills space between cells and slows down pathogens
Ground substance
What is the first connective tissue in embryos
Mesencyhm
What he the loose embryonic cr
Mucous connective tissue
What are neutrophils and eosinophils
Macrophages
What are the most common fibers in CTP
Collagen fibers
Which fibers are long straight and un branched fibers
Collagen fibers
Which fibers resist force in only one direction
Collagen fibers
What are some examples of collagen fibers
Tendons and ligaments
Which fibers are sting and flexible and resist force in many directions
Reticular fibers
Which fibers stabilize functional cells -parenchyma
Reticular fibers
Where is an sample of where reticular fibers are located
Sheath around organs
Which fibers are branched and wavy and contain elastin
Elastic fiber
Which fibers return to original length after stretching
Elastic fibers
What are the 3 types if loose connective tissue in the ADULT body
Areolar
Adipose
Reticular
Which is the least specialized loose ct and has an open framework
Areolar connective tissue
What kind if fibers does areolar tissue have
Elastic
Hat tissue holds blood vessels and capillary beds
Areolar tissue
Which kind if fat stores fat? Which kind breaks down fat
White-stores
Brown-breaks down
The adipocyte a that break down many mitochondria are found in what kind of tissue
Brown fat
Adipocytes don’t do what in adults
They don’t Divide
Adipocytes (in adults) expand to do what and shrink to do what
- expand to store fat
- shrink as fat is released
Which cells divide and differentiate
Mesenchymal cells
What are the two reasons for mesencephalon cells to divide and differentiate
- to produce more fat cells
- when more storage is needed
What tissue provides support
Reticular tissue
What are some organs that consist of reticular tissue
Spleen
Liver
Lymph nodes
Bone marrow
Which tissue is responsible for attachment and stabilization
Dense regular tissue
What tissue has tightly packed and parallel colleges fibers
Dense regular connective tissues
What attaches muscles to bone
Tendons
What connect bone to bone and stabilize the organs
Ligaments
what attaches in sheets on large flat muscles
Aponeuroses
Which tissue has strength in many different directions
Dense IRREGULAR tissue
The tissue that has interwoven networks of collagen fibers is what
Dense irregular ct
Which tissues
- layers skin
- are around cartilage
- are around bones
- form capsules around some organs
Dense irregular tissue
Where can elastic tissue be found
Ok the elastic ligaments if the spinal vertebrae
What are the two fluid connective tissues
Blood and lymph
What have a watery matrix of dissolved proteins
Fluid connective tissue
What are the three formed elements of blood
Red blood cells - erythrocytes
White blood cells - Leukocytes
Playlets
What are the three fluid components of the extra cellular part of blood
Plasma
Interstitial fluid
Lymph
Where is extra cellular fluid from the lymph collected from
Interstitial space
What are the two tissue fluid transport system
Cardiovascular system (blood) Lymphatic systems (lymph)
Cardiovascular system is composed of what three things
Arteries
Capillaries
Veins
What are the two supportive connective tissues
Cartilage and bone
