1. Chapter 2: Cells and Tissues
Lesson 2.3
Tissues

2. Types of Tissues epithelial tissue–lines and covers
connective tissue–supports
muscle tissue–generates force
nerve tissue–conveys information

3. Epithelial Tissue
apical (inside)
basal (outside)

4. Epithelial Cell Shapes
squamous
flat
cuboidal
square
columnar
tall

5. Epithelial Cell Arrangement
simple
one layer
stratified
more than one layer
other
transitional
stretchable

6. Epithelial Glands secrete substances exocrine endocrine unicellular
multicellular
simple
compound
endocrine

7. Review and Assessment
True or False? 1. Connective tissue provides support. 2. Transitional epithelial stretches. 3. Cuboidal cells are flat. 4. Stratified means more than one layer. 5. Epithelial glands secrete substances.

8. Connective Tissue functions fibers strengthens the body and organs
protects internal organs
maintains the shape of organs
provides rigid framework for muscles to pull
fibers
collagen
reticular
elastic

9. Classes of Connective Tissue
connective tissue proper
wide variety of locations and functions
plays a role in immune defenses
cartilage
provides support and flexibility
minimizes friction
bone tissue (osseous tissue)
provides framework, protects organs, supports body
blood
provides transportation, regulation, and protection
carries oxygen and nutrients, and carbon dioxide

10. Types of Connective Tissue
connective tissue proper
loose
dense
cartilage
bone

11. Loose Connective Tissue
areolar–under epithelium
reticular–spleen
adipose–fat

12. Dense Connective Tissue
regular dense–tendons
irregular dense–dermis
dense elastic–large artery walls

13. Cartilage chondroblasts hyaline elastic fibrocartilage
ends of long bones
elastic
external ear
fibrocartilage
intervertebral discs

14. Bone
osseous tissue
protects organs
supports the body

15. Types of Muscle Tissue
skeletal
cardiac
smooth

16. Nerve Tissue central nervous system peripheral nervous system
glial cells
neurons

17. Review and Assessment
Match the following with 1–4 below: skeletal, collagen, nervous tissue, elastic cartilage.
1. muscle tissue type
2. external ear
3. fiber
4. glial cells
