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)
