Term
Connective tissue is classified into:
Definition
proper, special, & adipose tissue
Term
The components of connective tissue are:
Definition
cells (fibroblasts/cytes), fibers, and ground substance
Term
The functions of CT are:
Definition
support, protection, defense, nutrition & storage, repair & regeneration
Term
The prodominant fiber type in proper CT is:
Definition
collagen
Term
Type I Collagen
Definition
fibrous tissue (skin, tendon, ligg), bone
Term
Type II Collagen
Definition
hyaline & elastic cartilage
Term
Type III Collagen
Definition
meshwork in liver & hematopoietic organs (reticular)
Term
Type IV Collagen
Definition
basement membrane
Term
Proper CT can either be _____ or _____.
Definition
loose, dense
Term
Dense CT is classified as either _____ or _____.
Definition
regular, irregular
Term
Loose CT
Definition
also called areolar CT
Term
Loose CT
Definition
loose, random arrangement of thin fibers; abundant ground substance; soft & compliant
Term
Loose CT
Definition
found in gut lamina propra, perivascular, surrounding glands, skin
Term
Regular Dense CT
Definition
fibroblasts; densely packed fibers; regular & parallel orientation; minimal ground substance
Term
Regular Dense CT
Definition
functions to connect muscle to bone; found in tendons & ligg
Term
Irregular Dense CT
Definition
few fibroblasts; thick, densely packed fibers in random orientation; minimal ground substance
Term
Irregular Dense CT
Definition
usually covered by epithelium; concentrated where forces from from different directions (skin)
Term
Special CT is different than Proper CT in the:
Definition
proportions of cells, fiber types and matrix
Term
The types of special CT are:
Definition
reticular, elastic, and mucous
Term
Reticular CT
Definition
delicate branched fiber network; can't see without routine stains
Term
Reticular CT
Definition
found in lymphatic/hematopoietic organs (lymph nodes, thymus, spleen), lung, liver
Term
Elastic CT
Definition
diffcult to see on H&E; function in stretching, elastic recoil, resiliance
Term
Elastic CT
Definition
found in vessels, external ear, vocal chords, trachea, lung, skin
Term
Mucous CT
Definition
embryonic type; predominant element = matrix; scarce fibers; low cellularity; non found in mammalian adults, rare in non-mammalian adults
Term
Mucous CT
Definition
found in comb of chicken, turkey wattles, umbilical cord, subdermal-embryo
Term
Ehlers-Danlos Syndrome
Definition
rare, heritable condition in which there is a lack of collagen tensile strength, resulting in skin hyperextensibility, joint laxity, skin & vessel fragility and poor wound healing
Term
The resident cells of CT are:
Definition
fibroblasts, macrophages, mast cells
Term
Fibroblasts/Fibrocytes
Definition
permanent cells that function in suport and healing & repair; fibroblasts are active in producing fibers and matrix; fibrocytes are inactive and impt in maintenance
Term
Fibroblasts & fibrocytes have a _____ shape with a _______, _______, ______ nucelus.
Definition
spindle; oval, elongated, flattened
Term
Macrophages' functions are:
Definition
phagocytosis and antigen presentation
Term
Macrophages are found:
Definition
in all tissues
Term
Macrophages are ________ and have _______, _______ nuceli and _______ cytoplasms.
Definition
round to polygonal; oval/indented, eccentric, pink to foamy
Term
Mast cells are seen in ______ numbers and are associated with ______.
Definition
low; blood vessels
Term
Mast cells function in _____ and are found in the _____, _____, and _____.
Definition
hypersensitivity; skin, respiratory tract, GI tract
Term
Mast cells are _____ with a ______, ______ nucleus and ________ cytoplasm. Their cell borders are _____.
Definition
"round"; round to oval, central; abundant; distinct
Term
The extracellular matrix is made up of:
Definition
ground substance and fibers.
Term
Components of ground substance include:
Definition
proteoglycans, glycosaminoglycans, and adhesive glycoproteins
Term
Adipose tissue is essentially _____. It can be broken into _____ & ______.
Definition
fat; white & brown
Term
White fat functions mainly in:
Definition
energy storage & shock absorption
Term
White fat is found:
Definition
almost everywhere
Term
White fat cells are _____ & ______ with ______, ______ nucleus and ______ cytoplasm filled with _______________.
Definition
large & polygonal; eccentric, flattened; scant; a large single lipid droplet
Term
Brown fat functions in:
Definition
heat generation
Term
Brown fat is found:
Definition
perirenal, interscapular, mediastium
Term
Brown fat cells are ______ with an ______, _______ & ________ nucelus and ________ cytoplasm.
Definition
smaller; eccentric, peripheral & "plump"; eosinophilic
Term
Brown fat is brown because of:
Definition
numerous mitochondria
