Tissue

QuestionAnswer
4 main groups of tissue Epithelial, connective, muscle, nervous
free surface of epithelial tissue apical surface
surface of epithelial opposite apical surface basement membrane
2 components of basement membrane basal lamina, reticular lamina
surface on which microvili and cilia form apical surface
Is epithelial vascular? No, avascular
Nerve cells between epithelial cells Innervated
1 layer of epithelial cells simple
multiple layers of epithelial cells stratified
3 shape classifications of epithelial cells columnar, cuboidal, squamous
Where are simple squamous epithelial tissue found? air sacs, kidney tubules
What is the epithelium called when it lines a blood vessel? endothelium
Where are simple cuboidal epithelium tissue found? Glands, glandular epithelium
Where are simple columnar epithelium tissue found? stomach lining to rectum, mucosa
What feature does the mucosa of the G.I. tract have? microvilli
What is the hollow space inside an organ called? Lumen
Where is pseudostratified ciliated columnar epithelium found trachea
what is the function of pseudostratified columnar epithelium? produce mucous
Where is stratified squamous epithelium found? skin, epidermis
What layer do we look to when naming epithelium cell shape? apical layer
Where is transitional epithelium found? Urinary bladder
Name 2 types of glandular epithelium exocrine, endocrine
what is the function of endocrine cells? secretions for internal use-hormones
what is the function of exocrine cells? secretions with transportation, i.e. tear ducts, sweat glands
What are the 3 components of connective tissue? cells, fibers, ground substance
What are the 3 types of fibers in connective tissue? collagen, elastic, reticular
What are the features of collagen fibers? good tensile strength, white fibers
What are the features of elastic fibers? elasticity, yellow fibers
What are the features of reticular fibers? lots of branches
What is contained in the ground substance of connective tissue? water, proteins, proteoglycans, gags
Name 4 types of cells found in CT fibroblasts, chondroblasts, oteoblasts, blood cells
What is all CT derived from? Mesenchyme in utero
What is the prototypical CT? Areolar
What cell is predominant in Areolar? Fibroblast
Name the types of CT CT proper, cartilage, bone, blood
Name the types of CT proper Loose CT and dense CT
Name the types of loose CT Areolar, adipose, reticular
Which CT is most abundant in the body? Areolar
Where is areolar CT located? against all epithelial tissue and all organs
What is the purpose of adipose ct? insulation, energy storage
Where is adipose ct found? subcutaneous, around organs
What does adipose ct consist of? large fat cell with little ECM
What does reticular ct consist of? Mainly reticular fiber
Where is reticular ct found? bone marrow, lymph nodes, spleen
Name the types of dense CT regular, irregular and elastic
Where is dense regular ct found? tendons and ligaments
What is a tendon? connects muscle to bone
What is a ligament connects bone to bone
What does dense regular ct consist of? mainly collagen fiber
Where is dense irregular tissue found? dermis of the skin
Where is dense elastic ct found? lungs and walls of big blood vessels
What is the function of dense elastic ct? expand and recoil
What fiber does dense elastic ct mainly consist of? elastic fibers
What are 3 types of cartilage? Hyaline, elastic, fibrocartilage
Where is hyaline cartilage found? ribs, rings of trachea, nose, ends of log bones
Which type of cartilage is most abundant? Hyaline cartilage
What cell is predominant in cartilage? Chondroblast/cyte
Where is elastic cartilage found? external ear, epiglotis
Where is fibrocartilage found? intervertable discs and meniscus of the knee
What cell is predominant in bone? osteoblast/cyte
What is the function of bone ct? structure, produce rbc, storage of minerals and salts
What is the most unique ct? Blood
What is the predominant cell in blood? blood cell
Where is the ecm produced for blood? bones and other places
Where is the ecm produced for other connective tissue? By the predominant cell for that CT
What is the function of blood ct? Transportation of materials throughout the body
