SOLUTIONS TO EXERCISES, LESSON 2
1. A tissue is a grouping of like cells working together. (para 2-1)
2. a. Epithelial.
b. Connective.
c. Muscle.
d. Nervous. (para 2-2)
3. Epithelial tissue is tissue that covers surfaces and lines cavities. (para 2-4)
4. If there are several layers and if the outer layer consists of flat cells, then the
tissue is called a stratified squamous epithelium. (para 2-6b)
5. Connective tissue is tissue that supports other tissues, holds tissues together, or
fills spaces. (para 2-7a)
6. The term used for material found among and outside the cells of connective tissue
is matrix. (para 2-7b)
7. The four major types of connective tissue (CT) are fibrous CT, cartilage CT, bone
CT, and fat CT. (para 2-8)
8. Characteristic cells of fibrous CT are fibroblasts. Cartilage cells are also called
chondroblasts. Cells that make and repair bone are osteoblasts. Cells that tear
down and remove bone are osteoclasts. (paras 2-9a, 2-10a, 2-11a)
9. The matrix of fibrous CT consists of fibers. The matrix produced by cartilage cells
appears homogeneous and amorphous. Fat CT has a matrix of lipid.
(paras 2-9b, 2-10b, 2-12b)
10. Two major types of fibrous connective tissue (FCT) are loose areolar FCT, which
is a filling substance around most organs and tissues of the body, and dense FCT,
which is found, for example, in ligaments and tendons. (para 2-9d)
11. Cartilage CT. (para 2-10b)
12. Fat CT. (para 2-12b)
13. Muscle tissues are tissues whose contracting elements enable muscles to produce
motion. (para 2-14)
14. Smooth muscle tissue. (para 2-15c)
15. Cardiac muscle tissue. (para 2-15b)
