zoology lab connective and microscopy cards

4 types of tissue

connectice

epithelial

nervous muscular

connective tissue functions

protection, support, binding

most connective tissue is highly

vascularized (has a lot of blood vessels)

types of fibroblasts

chondroblast → secrete matrix in cartilage

osteoblast- > secrete matrix in bone

what is the extracellular matrix secreted by

fibroblast or chondroblasts

what si the extracellular matric made up of

ground substance and fibers

classifications of connectvie tissue

loose

dense

cartilage

what are the loose connective tissue

areolar

adipose

reticular

dense connectuve tissue types

dense reg n irregular

cartilage tissues

hyaline

elastic

fibrous

where is areolar found

under all epithelia, between muscles passageway for nerves n blood vessels

adipose tissue

(the cells are)

adipocytes fir energy storage, insulation, n cushioning

in subcutaneous fat and packs around organs

reticular

found in lymph nodes, spleen, thymus, n bone marrow

t or f dense reg has high vascularity

false it has poor

dense reg

densely packed, tendons n ligaments hold bones tg n attach muscles to bones

it can resist stress from one direction bc of the parallel fibers

dense irregular is found where

lower layers of skin and fibrous capsule surrounding joints

can dense irregular withstand stress?

yes from many directions

what the the three types of cartilage

hyaline, elastic, and fibrous

what is cartilage

tough supportive conective tissue with rubbery matrix

does cartilage have blood vessels

no

chrondoblast produce matric and is called what when its surrounded

chondrocytes. lives in little spaces called lacunae

where is hyaline cartilage found

moveable joines, bone, noselarynx, trachea

hyaline cartilage

eases joint movements. chodrocytes randomly scattered

what the the mocroscope used called

binocular compound microscope

what is the distance between the eyepieces

interocular distance
