Connective Tissue:

what are 3 basic elements of connective tissue

cells, ground substance, fibers

what are the 7 types of cells in connective tissues

- fibroblasts

- chondrocytes

-osteoblasts

-adipocytes

- fixed macrophages

- melanocytes

- blood cells

what are fibroblasts

produce connective tissue fibers

what are chondroblasts

cartilage forming cells

what are osteoblasts

bone forming cells

what are adipocytes

fat forming cells

what are fixed macrophages

phagocytosis/ cleaning up debris

what are melanocytes

produce melanin

What are the 3 protein fibers found in connective tissue?

collagenous fibers

elastic fibers

reticular fibers

what are the 3 types of connective tissue

- connective tissue proper

- fluid connective tissue

- supporting connective tissue

what are the two subtypes of connective tissue proper

lose connective tissue and dense connective tissue

what are the 3 types of loose connective tissue

areolar, adipose, reticular

what is the description of adipose tissue

cells are called adipocytes "signet ring" storage

what is the function of adipose tissue

fat storage , energy storage and support and protection

where is adipose tissue located

behind eyes, around heart, kidneys, GI organs

what is the description of areolar tissue

loose network of 3 fiber types including collagenous, fibroblasts and reticular fibers

what is the function of areolar tissue

elasticity, support and shock absorption

where could areolar tissue be located at

subcutaneous layer of skin and around blood vessels + nerves

what is the description of reticular tissue

consists of a network of interlacing reticular fibers

what is the function of reticular tissue

to support many internal organs

where is reticular tissues located

liver, spleen, lymph nodes, bone marrow

what are the 3 types of dense tissue

regular, irregular, elastic

what is the description of dense regular connective tissue

collagenous fibers in tightly packed bundles with fibroblasts between bundle

what is the function of dense regular connective tissue

strong attachment between bones and muscles

where can dense regular connective tissue be located at

tendons, ligaments and connects muscle to muscle

what is the funcciton of irregular dense connective tissue

protective/prevents overextension and resists stress

where is irregular dense connective tissue located

dermis of skin, capsules of joints and organs

what is the function of elastic dense connective tissue

allows stretching

where is dense elastic connective tissue found

lung tissue and bronchial tubes and trachea

walls of arteries

ligamentum flava

How does the elastic tissue of arterial walls affect blood pressure?

elastic tissue in arterial walls stretch when heart pumps blood and then spring back when heart relaxes
