30. List the two types of embryonic tissue. What doesmesenchyme give rise to in the adult? What is the purposeof mucous connective tissue? 31. What are the three classifications of adult connectivetissue, and what tissue types are included in each? 32. Describe the fiber arrangement in loose (areolar)connective tissue. What are the functions of this tissuetype, and where is it found in the body? 33. What structural features distinguish adipose tissue fromother types of connective tissue? What is an adipocyte? 34. Name the two types of adipose tissue, and give thefunctions of each. Which type is primarily found in infants? 35. What is the function of reticular tissue? Where is it found?

36. Structurally and functionally, what is the difference betweendense regular connective tissue and dense irregularconnective tissue?

37. Name the two kinds of dense regular connective tissue,and give an example of each. Do the same for denseirregular connective tissue.

Supporting Connective Tissue

CartilageCartilage (kar′ti-lij) is composed of cartilage cells within anextensive and relatively rigid matrix. The surface of nearly allcartilage is surrounded by a layer of dense irregular connectivetissue called the perichondrium (per-i-kon′dr ē - ŭ m), described inmore detail in chapter 6. Cartilage cells arise from the
