d. does not have a duct and releases its product outside of the body

1. the two main components of the extracellular matrix which is prominent in some tissue types are ____ and ____

a. ground substance and mesenchyme
b. mucin and fibers
c. ground substance and fibers
d. ectoderm and endoderm

1. which of the following is not connective tissue?

c. a sweat gland
d. tendons and ligaments in the shoulder joint

1. which statement is false about connective tissue?

a. it includes cartilage, blood, and fat
b. it comes from the endoderm layer of the embryonic disc
c. most of the body is connective tissue
d. it has much extracellular matrix

1. which of the following tissue types has the greatest amount of extracellular matrix associated with it?

a. epithelial
b. connective
c. nervous
d. muscle

1. the main purpose of membranous epithelia is to

a. bind the body together and produce blood
b. produce movement
c. line and cover body surfaces
d. produce something and then release it, either inside the body or outside the body

1. a membrane that covers part of the body has multiple layers of cells. the cells are shield - shaped or scale - shaped on the surface of the membrane. what type of epithelial lining is it?

a. simple squamous
b. simple transitional
c. stratified squamous
d. stratified transitional

1. all epithelial tissue has a(n) ______ as part of its structure

a. basement membrane or basal lamina
b. extracellular matrix
c. embryonic disc
d. none of the above

1. which of the following membranous epithelia would be most likely to allow oxygen and nutrients to pass across it?

a. simple squamous
b. stratified squamous
c. simple columnar
d. pseudostratified ciliated columnar

1. which of the following membranous epithelia would provide the most protection and is found lining the oral cavity, nasal cavity, and the vaginal canal?

a. simple squamous
b. stratified squamous
c. simple columnar
d. pseudostratified ciliated columnar

Explanation:

1. Exocrine glands have ducts and release their products outside the body or onto an epithelial surface.
2. The two main components of the extracellular matrix are ground substance and fibers.
3. Connective tissues include cartilage, fat, tendons, etc. Sweat glands are epithelial - derived.
4. Connective tissue comes from the mesoderm, not endoderm.
5. Connective tissue has the greatest amount of extracellular matrix.
6. Membranous epithelia line and cover body surfaces.
7. Stratified squamous epithelium has multiple layers and scale - shaped cells on the surface.
8. All epithelial tissue has a basement membrane or basal lamina.
9. Simple squamous epithelium allows for the passage of oxygen and nutrients.
10. Stratified squamous epithelium provides protection and lines the oral, nasal, and vaginal cavities.

5. B. Connective
6. C. Line and cover body surfaces
7. C. Stratified squamous
