Flashcards in Histology Deck (91)
What are the four categories of tissues?
epithelial, connective, muscle, nervous
What does the Epithelial tissues include?
simple, stratified, pseudostratified, transitional, glandular
What are the shapes of epithelial tissue?
squamous, cuboidal, columnar
what are the three types of connective tissues?
protein fibers, mixed, fluid
what do the protein fibers include?
dense, loose, adipose, reticular
what do the mixed tissues include?
cartilage, bone, fluid
What are the only fluid connective tissues we have?
what are the 3 types of muscle tissue?
skeletal, smooth, cardiac
what are the types of nervous tissue?
An epithelial tissue that has one layer
An epithelial tissue that has many layers
filling between the cells
interstitial/ extracellular matrix
Most abundant tissue in the body
Where are connective tissues found?
throughout the body
What are connective tissues composed of?
Scattered cells with abundant intercellular material
What are the functions of connective tissues? (9)
bind structures, support, framework, fill spaces, store fat, produce blood cells, protects against infection, repairs tissue damage
produced by connective tissue cells and excreted to their exterior, separates living cells
what does the extracellular matrix consist of?
ground substances and fibers
composed of water and adhesion proteins
allowing connective tissue cells to attach themselves to the matrix fibers embedded in the ground substance
strands of collagen, elastin, or reticular protein
mixture of fibers and hard mineral deposits
protein fibers and ground substance
refers to cartilage
what are the 2 categories of connective tissues?
dense and loose
what do dense protein fiber matrix include?
regular and irregular
attachment for basement memberane
protein matrix with fat containing cells scattered throughout
netlike meshwork of the collagen fibers that helps hold tissues in place and sometimes helps to filter particles from fluids passing through it
what are the types of mixed matrix?
cartilage and bone
what are 3 types of cartilage?
elastic, hyaline, fibrocartilage
external ear, parts of larynx
ends of bones, joint linings
invertebral disks, knees and pelvic girdle
cartilage cells; lie within lacunae
what are the 2 types of bone tissues?
outer covering of all bones and along shafts of large bones
scaffolding of bone inside a shell of compact bone
liquid matrix (blood plasma) and circulating blood cells
Groups of cells with similar structures and functions working together to carry out a specific function
the study of tissues
exposed to outside or open space internally
lacks blood cells
prevents virus and bacteria to enter
what are the functions of tissues?
physical and chemical protection, sensory reception, secretion, absorption, excretion
looks like it's layered but it's not; nuclei in different spots of cells
pillar like cells
elastic cells that flatten as stretched
what are all epithelial tissues anchored to?
where is the simple squamous found?
lungs, capillaries, alveoli
what does the simple squamous do?
exchange gases, lines blood and lymph vessels and body cavities
Where are the simple cudboidal found?
ovaries, kidney tubules, ducts of glands
what does the simple cudboidal epithelium do?
secretion and absorption in kidneys, secretion in glands
where are the simple columnar found?
uterus, stomach, intestines
what does the simple columnar do?
protects underlying tissues, secretes digestive fluids, absorbs nutrients, increase surface area
where are the stratified squamous found?
skin, mouth, throat, vagina, anal canal
what does the stratified squamous do?
prevents water and substances from escaping, blocks chemicals and microorganisms
where are stratified cuboidal found?
mammary gland, sweat gland, pancreas, salivary glands
what does the stratified cuboidal do?
provides more protection
where are the stratified columnar found?
vas deferens, male urethra, parts of the pharynx
what does the stratified columnar do?
protects underlying tissue
where are the pseudostratified columnar found?
what does the pseudostratified columnar do?
line and sweep debris
where are transitional epithelium found?
urinary bladder, ureter, superior urethra
what does the transitional epithelium do?
desensibility and keeps urine from diffusing, expandable lining
where are the glandular epithelium found?
digestive system, respiratory system, skin, salivary, pancreatic, sweat, mammary glands
what does the glandular epithelium do?
secrete products into ducts, secrete in body fluids and blood
secretes products into ducts
secrete in body fluids and bloode
Considered to be organs because they are composed of more than one type of tissue
What are epithelial membranes made of?
Epithelium and connective tissue
What are the four main types of epithelial membranes?
Serous, mucus, synovial, integumentary
Most common connective tissue
cordlike or bandlike mass of white fibrous connective tissue that connects muscle to bone
cell that secretes mucus
concentric rings of bone cells
skin gland that secretes sebum
discs that provide special connection in cardiac muscle
protein in white fibers of connective tissues and in bone matrix
What are the characteristics of skeletal muscle?
What are the characteristics of smooth muscle?
What are the characteristics of cardiac muscle?
Where are nervous tissues located?
Brain, spinal cord, peripheral nerves
Bone forming cells
Refers to a type of cell
