(22 cards)
Loose connective tissue
Areolar(loose)
Adipose
Reticular
Dense connective tissue
Dense regular
Dense irregular
Elastic
Specialized connective tissue
Cartilage
Bone
Blood
Areolar connective tissue
Thin and delicate membranes, gel like ground substance
Fibroblasts that have collagen and elastic fibers
Location:sub Q layer, under epithelia
Function:nourish nearby epithelial cells
Adipose tissue
Fat that push nuclei to one side
Function:cushion and insulate
Location:sub Q layer
Reticular Connective Tissue
Made of thin reticular fibers
Function:supports walls of internal organs
Location:walls of liver,spleen
Dense Regular Connective Tissue
Closely packed collagen fibers and elastic fibers
Very strong withstands pulling
Function:binds body parts
Location:tendons,ligaments, dermis
Dense Irregular Connective Tisse
Randomly organized, interwoven collagen
Function:withstand tension exerted from different directions
Location:dermis/around skeletal muscles
Elastic Connective Tissue
Abundant elastic fibers
Function:stretch
Location:between bones of spine;walls of hollow organs; parts of heart
Cartilage
Rigid,support,frame work,attachments Protective of underlying tissue Models for developing bone In gel like ground substance Lacks good blood supply,heals slowly 3 types Hyaline Elastic Fibrocartilage
Hyaline cartilage
Most common Fine collage Ends of bones Nose Embryonic skeleton
Elastic Cartilage
Flexible due to elastic fibers in matrix
External ear,larynx
Fibrocartilage
Very tough due to collagen
Shock absorber
In vertebral disks
Pads of knees and pelvic girdle
Bone (Osseous tissue)
Solid matrix made from mineral (Ca) salts and collagen
Function:supports structure,protects vital structures, produces blood cells, stored and releases G,P
2 types:compact and spongy
Blood
Fluid matrix(plasma)
Red blood cells-transport substances in the body
White blood-transport and fight infection
Contractile
Can shorten and thicken
Muscle tissue types
Skeptical,cardiac, and smooth
Skeletal muscle tissue
Striated
Voluntary
Multinucleated
Stimulated by nerve cells
Smooth muscle tissue
Non-striated Spindle shaped fibers Hollow organs Walls of blood vessels Involuntary
Cardiac muscle tissue
Only in wall of the heart Branching cells Involuntary Striated Intercalated discs
Nervous tissue
Found in brain,spinal cord,and peripheral nerves
Main cells are neurons,specialized communication
(Sensory reception,motor control)
Neurons coordinate,integrate,& regulate body functions
Neuralgia
Support and nourish neutrons
