Chapter 4 Flashcards
epithelial
covers body surfaces, hollow surfaces, and body cavities, little intercellular space, avascular
connective
protects and supports, intercellular space filled with matrix (nonliving), highly vascular
muscle
makes body parts move
nervous
detects stimulus inside and outside the body
tight junction
membranes of cells almost completely fused
gap junctions
tubular channels (connexons) link cells and membranes are not tightly fused
desmosomes
cadherins anchors parts of the membranes to each other
simple squamous
fxn: diffusion, filtration, secretions
location: BV, lungs, kidneys, serous membrane
simple cuboidal
fxn: secretions and absorption
location: glands, ovaries, kidney tubes
nonciliated
fxn: secretion and absorption
location: gastrointestinal tract
stratified squamous
fxn: protection
location: outer layer of skin, mouth, and tongue
stratified cuboidal
fxn: protection and some secretion and absorption
location: sweat glands, esophageal glands
ciliated
fxn: move mucus and other substances across cells
location: upper respirator tract, uterus
endocrine glands
ductless, pass secretions through the blood
transitional
fxn: permits distension
location: urinary bladder, urethra, ureters
stratified columnar
fxn: protection and secretion
location: urethra, large secretory ducts
psuedostratified columnar
fxn: secretion, movement
location: airways, glands
simple branched tubular
gastric glands
exocrine glands
ducts, secretions emptied onto bodies surfaces or lining epithelium
simple tubular
location: large intestines
simple coiled tubular
sweat glands
simple acinar/ alviolar
male urethra
compound tubular
bulbourethral glands
simple branched acinar/ alviolar
sebaceous glands
compound acinar/ alviolar
mammary glands
compound tubuloacinar
pancreas
merocrine
mainly fluid secretions
holocrine
cell ruptures (whole cell in the secretions)
apocrine
part of cells are in secretions
plasma cells
secrete antibodies
fibroblasts
secrete fibers and matrix
mesenchymal cells
fibroblasts- loose/dense CT, chondroblasts- cartilage, osteoblasts- bone
macrophages
engulf (eat) foreign particles and worn out parts
mast cells
produce histamines
adipocytes
store fats
reticular
fine bundles pf collagen, branched for support
white blood cells
fight infections
elastic
extremely flexible, not as strong as collagen
collagen
extremely strong, great tensile stength
areolar
fxn: binds body parts
location: small BV, nerves, subcutaneous
look: dark red lines, thin lines, and dark spots in the back
adipose
fxn: nutrient storage, protection, and insulation
location: fat
look: wide white circles (fat), thin lines around
reticular
fxn: internal framework
location: lymphatic system, bone marrow
look: pretty, black lines, smaller circles, mr thomas wants it for his wife
dense regular
fxn: strengthen attachments
location: tendons and ligaments
look: waves patterns, no space, densely compacted
dense irregular
fxn: strengthen tissue
location: dermis, bones, and pericardium
look: irregular pattern, no space, densely compacted
elastic CT tissue
fxn: allows stretching of many organs’
location: arteries, trachea, lung tissue
look: squiggly lines across
hyaline
fxn: support
location: end of nose, in your bones
look: circular cells w nucleus (eyes) in smooth space, no fibers
fibrocartilage
fxn: strong support withstand heavy pressure
location: intervertebral discs
look: always blue, pattern
elastic cartilage
fxn: support and give shape
location: external ear, larynx
look: not much space, many eyes, compacted
bone
fxn: support, protect, store, attachment
location: bones
look: like a tree, concentric rings, black holes (osteocytes)
blood
fxn: transport and protect
location: heart and BV
look: bunch of circles, some look different (white blood cell)
lymph
fxn: protect
location: lymphatic vessels and organs
look: many tiny dark circles, no space
skeletal
fxn: voluntary movement, striated

nervous
fxn: regulate and control body functions
location: nerves
look: hand, has axon and smaller ending dendrites
neurons
generate and conduct electrical impulses
neuroglial
support, insulate, and protect neurons
regeneration
fully regenerates and looks normal after
ex. skin
fibrosis
tissue tries to repair but is interrupted
ex. scar
