Ch 3 Flashcards
Types of fibrous CT
loose connective tissue, dense connective tissue
Areolar Tissue
Loose fibrous connective tissue: highly vascularized, underlies most epithelia
Reticular tissue
Loose fibrous connective tissue: reticular fibers, found in spongy organs
Dense regular connective tissue
diensely packed with collagen fibers, wavy lines that don’t cross over. not stretchy. tendons and ligaments.
Elastic Tissue
dense CT, contains elastic fibers. wavy squiggly lines. vocal cords
Dense Irregular connective tissue
marbled meat, places that need to resist stress in multiple directions. Densely packed w collagen fivers. Dermis of the skin
Adipose Tissue
CT stores triglycerides. -white fat(adipose) -brown fat
Cartilage
long healing time. flexible rubber matrix
Chondroblasts
cartilage producing cells
Chondrocytes
mature cartilage cells
Hyaline cartilage
bone development, supports the respiratory tract, articular surface of bone
Fibrocartilage
Intervertebral discs, in knee
Elastic cartilage
Flexible elastic support, helix of ear
Blood
CT. Erythrocytes(red), Leukocytes(white), Platelets. Plasma: fluid ground substance
Muscle contraction
changes in voltage is the stimulus
Nervous Tissue
Electrical and chemical signals. Dendrites(projections). Coded info
Neuroglia (glial cells)
Protect and assist neurons, physically support neurons, all other cells around neurons
Three types of muscles
skeletal, cardiac, and smooth
Skeletal
multi nuclei, striations, long cells
Cardiac
branched in nature, glycogen, striations,
Smooth
not striated, taper at end, digestive tract, blood vessels.
Mucous
line passageways to openings. three layers -epithelium(varies) -lamina propria (areolar CT) -muscularis mucosae (smooth muscle layer)
Serous
Lines body cavities. - double walled (visceral and parietal), serous fluid fills the space. -Epithelium
parts of serous tissue?
areolar tissue, smooth muscle, simple squamous
Hyperplasia
growth through cell multiplication
Neoplasia
tumor cells.
Hypertrophy
enlargement of cells
Metaplasia
changing from one mature tissue to another. (normal)
Differentiation
more specialized form (sometimes abnormal)
Regeneration
replacement of damaged or dead cells
