Chapter 4 Epithelial tissue Flashcards
Use the key to classify each of the following described tissue types into one of the four major tissue categories.
Key:
A - Connective tissue
B - epithelium
C - muscle
D - nervous tissue
- tissue type composed largely of nonliving extracellular matrix; important in protection and support
- the tissue immediately responsible for body movement
- the tissue that enables us to be aware of the external environment
- the tissue that lines our body cavities and covers surfaces
- A
- C
- D
- B
An epithelium that has several layers, with an apical layer of flattened cells is called
A. ciliated
B. columnar
C. stratified
D. simple
E. squamous
E
the gland type that secretes products such as milk ,saliva ,bile or sweat through a duct is called
A. an endocrine gland
B. an exocrine gland
B. exocrine gland
the membrane which lines body cavities that open to the exterior is a
A. endothelium
B. cutaneous membrane
C. mucous membrane
D. serous membrane
C. serous membrane
scar tissue us a variety of
A. epithelium
B. connective tissue
C. muscle tissue
D. nervous tissue
E. all of the above
B. connective tissue
name the primary cell type
in connective tissue
In cartilage
In bone
Fibrocyte, chondrocyte and osteocyte
name the two major components of the extracellular matrix and if applicable subclass of each component
fibers and ground substance
Subclass of fibers: collagen, elastic, and reticular
Subclass of ground substance: interstitial fluid, cell adhesion proteins and proteoglycans
name the specific connective tissue type found in the following body locations
A. forming the soft packing around organs
B. supporting the ear pinna
C. forming “stretchy” ligaments
D. first connective tissue in the embryo
E. forming the intervertebral discs
F. covering the ends of bones at joint surfaces
G. main component of subcutaneous tissue
A. areolar connective tissue
B. elastic cartilage
C. elastic connective tissue
D. mesenchyme
E. fibrocartilage
F. hyaline cartilage
G. adipose tissue
what it the function of macrophages
defend immune system and destroy bacteria, dead cells and other debris
Name the special characteristics of epithelium
(CAP VR)
cellularity, attachment, polarity, vascularity, and regeneration
what functions does epithelial tissue accomplish
- protection
- absorption
- filtration
- excretion
- secretion
-sensory
Describe the exocrine gland
- secretes oil, mucus, sweat onto the body
describe the endocrine gland
- secretes hormones into the blood
- loses duct during development
what does simple epithelial tissue do
- absorbs, secretes and filtrates
where do you find stratified tissue ?
high absorption areas and protection areas
