Term
connective tissue
Definition
-most abundant tissue in the body
-composed of an abundant amount of intercellular material (ground substance and fibers)
-generally highly vascular
Term
connective tissue functions
Definition
-protection
-supports and bind other tissues together
-provides metabolic needs of other tissues
Term
types of connective tissue
Definition
-connective tissue proper
-cartilage
-bone
-blood
Term
ground substance function
Definition
-serves as a pathway for the transport and exchange of nutrients and waste products between blood and the tissue cells
Term
ground substance
Definition
-a homogenous material produced by connective tissue cells
-varies in consistency
-fluid-semisolid
-blood-bone
Term
fibers
Definition
prove strength and flexablity
Term
types of fibers
Definition
collagenous, elastic, reticular
Term
collagenous fibers
Definition
-principle type
-composed of protein collagen
-flexible but strong
Term
elastic fibers
Definition
composed of protein elastin which is capable of stretching
Term
reticular fiber
Definition
thin threads for a delicate network; meshlike
Term
fibroblast
Definition
most abundant cell
-star or elongated cell which produces and maintains CT fibers
Term
fat cells
Definition
-adipocytes
-stores lipids
Term
macrophages
Definition
engulf bacteria and debris
Term
connective tissue proper types
Definition
loose (areloar)
dense
elastic
adipose
Term
loose (areloar) CTP
Definition
-abundant intercellular material
-few cells
-few scattered fibers
-very vascular
-very flexible
Term
location of loose CTP
Definition
-packing material around organs
-surrounds muscles and blood vessels
-binds skin to underlying muscle
Term
dense CTP
Definition
-large number of collagenous fibers packed closely together
-poor blood supply
-strong yet flexible
Term
location of dense CTP
Definition
-ligaments
-tendons
-outer covering of eye
Term
elastic CTP
Definition
-contains many irregularly arranged elastic fibers
-can be easily stretched and returned to original size
Term
location of elastic CTP
Definition
-walls of arteries
-larynx
-trachea
-bronchi
Term
adipose CTP and location
Definition
-composed of fat cells
-located throughout body
Term
cartilage composed of
Definition
intercellular matrix, cells, fibers
Term
cartilage intercellular matrix
Definition
chondroitin sulfate-semisolid gelatin like substance
Term
cartilage cells
Definition
chondrocytes - live in small space called lacunae
Term
perichondrium
Definition
tough outer covering of cartilage
Term
cartilage vascular or avascular?
Definition
avascular, uses diffusion
Term
types of cartilage
Definition
hyaline, fibrocartilage, elastic
Term
hylaine cartilage
Definition
-forms a cartilagenous skeleton which serves as a model during fetal development
-covers the surface of long bones at a joint "articular cartilage"
-found in portions of respiratory tract (nose, trachea, bronchi, ends of ribs)
Term
fibrocartilage
Definition
-contains more fibers, able to withstand compression
-fibers arranged in parallel bundles; increase in tensile strength
-found in intervertebral disc and symphysis pubis (b/w pelvis)
Term
elastic cartilage
Definition
-contains numerous elastic fibers for increased flexibility
-found in auditory (eustachian tube) ear to throat
-external ear
-larynx
-epiglottis
