term | definition |
histology | study of tissues |
tissue | cells, intercellular substances, tissue fluids |
tissue types | epithelial, connective, muscle, nervous |
Epithelial is | lining of body cavities, covering tissues, skin and organs |
epithelial perfomrs | protection and secretion |
epithelial shape | squamous, cuboidal, columnar, transitional |
epithelial arrangement | simple; statified, pseudostratified |
simple | one cell layer |
stratified | 2 or more layers (protection0 |
pseudostratified | appear stratified, are simple |
squamous | thin, flat, irregular ex. lining of mouth |
cuboidal | cube, ducts of kidneys |
columnar | long thin, respiratory tract, fallopian tubes uterus |
transitional | change shape, urinary bladder cube to squamous |
simple squamous | little wear and tear and high osmosis, heart, blood vessels |
stratified squamous | check cells, skins etc. |
simple cuboidal | thyroid glands, ovaries, lens of eyes |
transitional epithelium | lining of bladder |
simple columnar | stomach, intestines |
pseudostratified columnar | respiratory tract, male repro |
glandular epithelium | exocrine, outside; endocrine, pituitary gland |
Connective tissue | most abundant, highly vascular, binds and support other structure, small # of cells and large amts of inercellular subs. |
Connective tissue types | proper, loose, dense, specialized: bone, cartilage, blood etc. |
Connective tissue fibers | collagen, elastic, reticular |
Loose connective tissue proper | areolar, adipose, hypodermis |
adipose tissue | fat, insulation, protection, support, food storage, between organs |
hypodermis | below the skin, cellulite |
Loose connective tissue cells | fibroblast, fibrocyte form fibers and round substanse after injury |
Plasma cells | from lymphocytes, anibodies |
Dense connective tissue | tendons, ligaments, dermis |
areolar tissue | collagen and elastin fibers, support blood vessels, nerves, Interal organs, binds muscle and skin to underlying tissue |
adipose tissue | fat, insulation, protection, support food storage |
hypodermis | below the skin (areolar and adipose) |
collagen | tough, thick, ligaments, tendons |
Ligaments | connect bone to bone |
tendons | connect muscle to bone |
elastic | thing fibers that stretch, bladder, lungs, stomack |
reticular | thin, shiny refractile, translucent, binds smooth muscle and form framework, lymph noes, bone marros |
fibrocyte | fibroblast, form fibers and ground substance after injury |
macrophage | monocyte, phagocytosis |
plasma cells | lymphocytes, anitboides, provide defense |
mast cells | produce anitcoagulant, heparin as well as histamines |
melanocytes | pigment cell |
adipocytes | fat cells |
leukocytes | granulocytes, agranulocytes |
Proper | loose few fibers; dense many fibers |
specialized | bone, cartilage, blood and lymph |
specialized connective tissue | cartilage, bone |
Cartilage general | shock absorber; avascular |
cartilage hyaline | most common, smooth surface, at joints over long bones |
cartilage white fibrous | in between veterbrae along the spine |
cartilage elastic | provides strength and maintains shape of organs, epiglottis, pinna, auditory canal |
bone tissue - osseous | skeletal system, protects, supports, movement, calcium and phosphoros storage, red marros |
Osteoblasts | bone forming cell, osteocyte, located in the lacuna |
spongy | bone, cancellous, inside |
compact | bone, dense, outside of long bone, arranged in circles (haversian) |
haversian system | basic unit of compact bone |
