16
Q

3 types of dense connective tissue

A

elastic, regular, irregular

17
Q

3 types of loose connective tissue

A

areolar, reticular, adipose

18
Q

features of connective tissue

A

nerve supply, vascular (except cartilage and tendons), more ECM than epithelia.

19
Q

3 types of fibers

A

collagen, elastic, reticular

20
Q

areolar loose connective tissue

A

surrounds organs, fibroblasts, all 3 fiber types, contains macrophages, important for inflammation response, lamina propia

21
Q

adipose loose connective tissue

A

cushioning, insulation, food source. Example: mammary tissue. nucleus pushed to the side by fat droplets, located in hypodermis

22
Q

reticular loose connective tissue

A

soft internal skeleton, spleen, lymph organs

23
Q

dense connective tissue regular

A

tendons, ligaments, unidirectional tensile strength

24
Q

dense connective tissue irregular

A

capsule for joints, multidirectional tensile strength

25
Q

dense connective tissue elastic

A

flexible, coverings of large arteries

26
Q

hyaline cartilage

A

forms structure of nose, trachea, larynx, costal cartilage on ribs, has lots of collagen fibers. supports, cushions, reinforces. Cell is the chondrocytes/blasts

27
Q

3 types of cartilage

A

hyaline, fibrocartilage, elastic

28
Q

elastic cartilage

A

stretchy but maintains structure, pinna of ear

29
Q

fibrocartilage

A

tensile strength wit shock absorption, intervertebral discs, knee discs

30
Q

bone

A

hard, calcified matrix. Produces blood cells in marrow, stores minerals and fat, structural support, lever for skeletal muscles, well vascularized

31
Q

myofilaments

A

bring about movement or contraction of cells to create change in body/organ

32
Q

skeletal muscle

A

long, striated cylindrical multinucelate cells, voluntary movement, attached to bones or sometimes skin

33
Q

cardiac muscles

A

involuntary. branching, striated, uninucleate that interdigitate at specialized junctions (intercalated discs). propels blood into circulation as it contracts. located in walls of heart

34
Q

smooth muscle

A

involuntary, no striations, spindle shaped cells with central nuclei, cells closely arranged to form sheets. propels substances like food, urine, a baby along internal passageways. found in most walls of hollow organs
