Tissues Flashcards
Cells arranged around central canals within bone matrix
osteocytes
Matrix ground substance (cartilage) is made up of
chondroitin sulfates and glucosamine
The only connective tissue that is avascular
cartilage

embryonic connective tissues > mesenchyme (embryonic stem cells) + loose embryonic connective tissue
What is the connective tissue that connects to the epithelium?
Basal lamina
Muscle type(s) that have a single nucleus
cardiac and smooth
Muscle type(s) that is/are multinucleated
skeletal
Muscle type(s) that is/are striated
skeletal and cardiac
Connective tissue matrix consists of
ground substance (areolar, bone, cartilage, blood)
fibers (collagen, elastic, reticular)
Tendons, ligaments, aponeuroses (tissue type)
connective tissue - dense regular (parallel, one direction)
Muscle type(s) that are non-striated
smooth
Muscle type(s) that are involuntary
cardiac and smooth
What determines the characteristics of connective tissue?
ground substance
Cells in all mucous membranes
goblet cells
Ground substance of connective is made up of what four elements?
Blood (like water)
Areolar (hyaluronic acid - viscous) (joint fluid)
Cartilage (chondroitin and glucosamine)
Bone (calcium salt)
The connective tissue matrix is made up of?
Ground substance and fibers (collagen, elastic, reticular)
Cells that make up cartilage
chondroblasts
What is connective tissue made of?
Cells and Matrix (ground substance + fibers)
connective tissue proper (cells, fibers, gelatinous ground substance)
supportive connective tissue (cells, fibers, solid ground substance)
fluid connective tissue (watery matrix)
Areolar tissue consists of what two fibers
collagen and elastic
Formed elements of blood
RBC, WBC, platelets
Supportive connective tissue
bone and cartilage
Three types of cartilage
hyaline (most common)
fibrous
elastic
Types of connective tissue fibers
collagen (force one direction - tendons and ligaments) elastic (return to original - ligaments of vertebrae) reticular (force many directions - organs)
Serous membranes - ventral cavity (tissue type)
simple squamous epithelial AND areolar
Cells that make up blood
hematopoietic stem cells
Three classifications of connective tissue
connective (connect & protect) fluid (transport) supportive (structure)
Two types of embryonic connective tissue
mesenchyme (stem cells)
mucous (loose connective tissue)
Cells that make up bone
osteoblasts
Scattered cells of areolar
fibroblast and mast cells
Cutaneous membrane
epidermal layer (keratinized stratified squamous)
outer papillary layer (aerolar)
First connective tissue in embryos
mesechyme (embryonic stem cells)
Type of connective tissue - skin, cartilages, bones, capsules around organs
dense irregular
Tissue type of synovial membranes (moving, articulating, joint cavity lining)
mostly areolar (produces synovial fluid)
Types of connective proper cells (connect and protect)
fibroblasts (hyaluronan) fibrocytes (maintains fibers) macrophages (clean up pathogens) adipocytes (fat) mesenchymal (stem cells) melanocytes (melanin) mast cells (histamine / heparin) lymphocytes (plasma cells) microphages (neutrophils / eosinophils)
Ground substance that is like water
blood

areolar; made up of collagen and elastic fibers + scattered fibroblast and mast cells
Covers bone surfaces
periosteum
What are the three things that connective tissue provides?
Structure (bone)
Energy (fat)
Transport (blood)
Ground substance of cartilage is made of
chondroitin and glucosamine
Three fibers make up connective tissue
Collagen, elastic, reticular
Type of cartilage that reduces friction between bones
hyaline (joints, rib, sternum, trachea)
Type of scattered cells in areolar
fibroblast and mast cells
Fibrous cartilage is found
knee, pubic, vertebrae
Ground substance of bone is made of what that makes it hard
calcium salts
In connective tissue, there are few cells in
ground substance
Two characteristics of connective tissue
vascular (EXCEPT cartilage) and innervated
Four types of membranes
mucous
serous
cutaneous
synovial
reticular (loose connective tissue)
supports parenchyma
spleen, liver, lymph nodes, bones marow
Type of cartilage that is supportive but bends easily
elastic
Fluid connective tissue
watery matrix with dissolved proteins
blood - RBC, WBC, platelets
Three serous membranes
pleura
pericardium
peritoneum
Type of cartilage that limits movements and prevents bone to bone contact
fibrous
Three types of loose connective tissue (in adults)
areolar (collagen and elastic fibers) adipose reticular
Tissue found under epithelium
areolar
Three types of muscle tissue
skeletal cardiac smooth
Ground substance always below the epithelium
areolar
Three levels of serous membrane
transudate
mesothelium
areolar
areolar (viscous ground substance)
hyaluronic acid
Where would you find elastic cartilage?
ear and epiglottis
Type of scattered cells in cartilage
chondrocytes
Serous membrane internal and external portions that line
parietal - out
visceral (serosa) - in
Ground substance is made up of what cells
blood, areolar, cartilage, bone
Cells that make up connective tissue proper
fibroblasts
Ground substance of areolar is made of
hyaluronic acid (make viscous)
Types of dense connective tissue
dense regular (parallel - one direction)
dense irregular (network - many directions)
elastic tissue
