Question 5

hyaline cartilage

Answer 5

most common one; contains closely-packed collagen fibers making it tough yet flexible; connects ribs to sternum, supports respiratory tract

Question 6

fibroblasts

Answer 6

most common in connective tissue proper; produces and maintains the connective tissues fibers and ground substance

Answer 7

densely interwoven making them durable and tough and has little ground substance; lie between vertebrae of spinal column

Question 8

muscle types

Answer 8

skeletal, cardiac, smooth

Question 9

skeletal muscle

Answer 9

large multinucleated cells; form muscle fibers; marked by striations; striated voluntary muscle

Question 10

cardiac muscle

Answer 10

heart muscle; short branched and straited; usually with single nucleus; cells connected by intercalated discs

Question 11

smooth muscle

Answer 11

short spindle shaped and nonstriated with single central nucleus
found in blood vessels, digestive, respiratory, and urinary tracts
