The four basic tissues

1.      Which of the following tissues is avascular?

a)      Bone
b)     Adipose
c)      Muscular
d)     Stratified squamous epithelial
e)      Nervous
f)       Areolar

2.      The four types of tissues are_____ , _____,______ , and_____ .

a)      Adipose, nervous, muscular and epithelial
b)     Epithelial, muscular, connective and bone
c)      Epithelial, muscular, blood and adipose
d)     Nervous, epithelial, connective and muscular

3.      For each of the following items, indicate the tissue type with which they are associated. Use E for epithelial tissue, C for connective tissue, M for muscle tissue, and N for nervous tissue.

____(a) binds, supports
____ (b) contains elongated cells that generate force
____ (c) neuroglia
____ (d) avascular
____ (e) may contain fibroblasts
____ (f) tightly packed cells
____ (g) intercalated discs
____ (h) goblet cells
____ (i) contains extracellular matrix
____ (j) striated
____ (k) generate action potentials
____ (l) cilia
____ (m) ground substance
____ (n) apical surface
____ (o) excitable

4.      Match the following epithelial tissues to their descriptions:

____(a) contains a single layer of flat cells; found in the body where filtration (kidney) or diffusion (lungs) are priority processes
____ (b) found in the superficial part of skin; provides protection from heat, microbes, and chemicals
____ (c) contains cube-shaped cells functioning in secretion and absorption
____ (d) lines the upper respiratory tract and uterine tubes; wavelike motion of cilia propels materials through the lumen
____ (e) contains cells with microvilli and goblet cells; found in linings of the digestive, reproductive, and urinary tracts
____ (f) found in the urinary bladder; contains cells that can change shape (stretch or relax)
____ (g) contains cells that are all attached to the basement membrane, although some do not reach the surface; those cells that do extend to the surface secrete mucus or contain cilia
____ (h) a fairly rare type of epithelium that has a mainly protective function

(1) Pseudo stratified ciliated columnar epithelium
(2) Ciliated simple columnar epithelium
(3) Transitional epithelium
(4) Simple squamous epithelium
(5) Simple cuboidal epithelium
(6) Nonciliated simple columnar epithelium
(7) Stratified cuboidal epithelium
(8) Keratinized stratified squamous epithelium

5.      Match the following connective tissues to their descriptions:

____(a) the tissue from which all other connective tissues eventually arise
____ (b) connective tissue with a clear, liquid matrix that flows in lymphatic vessels
____ (c) connective tissue consisting of several kinds of cells, containing all three fiber types randomly arranged, and found in the subcutaneous layer deep to the skin
____ (d) a loose connective tissue specialized for triglyceride storage
____ (e) tissue that contains reticular fibers and reticular cells and forms the stroma of certain organs such as the spleen
____ (f) tissue with irregularly arranged collagen fibers found in the dermis of the skin
____ (g) tissue found in the lungs that is strong and can recoil back to its original shape after being stretched
____ (h) tissue that affords flexibility at joints and reduces joint friction
____ (i) tissue that provides strength and rigidity and is the strongest of the three types of cartilage
____ (j) bundles of collagen arranged in parallel patterns; compose tendons and ligaments
____ (k) tissue that forms the internal framework of the body and works with skeletal muscle to generate movement
____ (l) tissue that contains a network of elastic fibers, providing strength, elasticity, and maintenance of shape; located in the external ear
____ (m) connective tissue with formed elements suspended in a liquid matrix called plasma


(1) Blood
(2) Fibrocartilage
(3) Mesenchyme
(4) Dense regular connective tissue
(5) Lymph
(6) Hyaline cartilage
(7) Dense irregular connective tissue
(8) Areolar connective tissue
(9) Reticular connective tissue
(10) Bone (osseous issue)
(11) Elastic connective tissue
(12) Elastic cartilage
(13) Adipose tissue
