Tissues Flashcards
four types of tissues
epithelial
connective
muscular
nervous
epithelial: constitutes?
shortage of ?
some functions?
superficial outer layer of mucuous membranes and cells
-skin, linings of major body cavities and tubes
intercellular matter
secretory, absorption, cilia (actively beat to remove contaminants)
simple epithelium:
SCCC
compound epithelium:
ST
-
squamous
cuboidal
columnar
ciliated
stratified
transitional
basement membrane
Simple epithelium: single ? squamous (aka): - -line? cuboidal (aka): -what shape -what function columnar: -shape -inner lining of ? ciliated: shape lining of ?
layer of cells
(pavement) :
- flat
- blood vessels, heart, alveoli, lymphatic vessels
cubical:
- cube shaped
- secretory functions like in thyroid
cylindrical; stomach, intestines, gall bladder, bile ducts
cylindrical with cilia; nasal cavities, larynx, trachea, bronchii
compound epithelium: different? stratified: what are they ? where are they? transitional: what shape cells? lining of ?
layers of cells
flattened cells on bed of columnar cells
-skins epidermis, conjunctiva, lining of mouth, pharynx and esophagus
pear shaped
bladder
basement membrane: also called ? made predominantly of? underlies? serves functions like? and ? joins ?
baseplate collagen epithelial tissues stabilization and directing growth pattern of epithelial cells epithelial and connective tissues
connective tissue:
composed predominantly of?
connective tissue may be?
intercellular material called matrix
solid, liquid or gel like
connective tissue: areolar: - -supports -between adiopose: cells with? between? white fibrous: characteristics where is it found?
elastic
- organs
- muscles
fat globules
muscles and organs
strong, closely packed
-ligaments binding bones, periosteum covering bone, covering of organs, fascia over muscles
yellow elastic:
- characteristic
- found in areas requiring?
lymphoid: make up
elastic
-recoil like trachea, cartilage, bronchii, lungs
lymphocytes
-lymphoid tissue of tonsils, adenoids, and lymphatic nodes
connective tissue:
cartilage (…)
hyaline cartilage: what color? , what texture? found on ?
fibrocartilage: characteristics: found in ?
function?
yellow (elastic) cartilage: characteristic
found in
firm and flexible
bluish-white, smooth; articulating bone surfaces, costal cartilages of ribs, larynx, trachea and bronchial passageway
dense, white, flexible; intervertebral disks and between surfaces of knee joints
-shock absorber
firm elastic
-pinna and epiglottis
connective tissue continued:
blood:
bone: ... connective tissue compact bone: what structure? what does lamallar mean? cancellous or ? bone: what appearance? haversian canals are ? red bone marrow produces ?
corpuscles (red cells, white cells), platelets, blood plasma
hardest!
haversian canal
lamellar structure (sheet like)
spongy; larger than in compact bone; red and white blood cells and plasma
muscular tissue:
striated: what appearence under microscope ?
- what muscles
- what action?
smooth: usually ? with what shaped cells
- muscles of ?
- what action?
cardiac: cells ?
- combo of ?
- what action
specialized contractile tissue
striped
- skeletal muscles
- voluntary
sheet like with spindle shaped cells
- internal organs
- involuntary
inter-connect in net-like fashion
- striated and smooth
- involuntary
nervous tissue: highly ? transmits information from ? neruons: glial cells:
specialized communicative tissues
-one neuron to another, neurons to muscles, sensor receptors to other neural structures
transfer info; comm. tissue
nutrient transfer; blood brain barrier
some protective cells:
fibroblasts: produce? synthesize and secrete? involved in?
macrophages: collect and ?
extracellular matrix; protein, wound repair
digest waste and necrotic tissue
protective cells cont.:
B-lymphocytes: arise from ? presence of foreign matter will ?
T-lymphocytes: arise from ? and end up in ? simulated to ?
bone marrow; stimulate their proliferation within lymph tissue, generate and secrete antibodies
bone marrow; thymus, seek and destroy viral agents
