Section 1 — The Four Primary Tissue Types
Figure 1. The four primary tissue types: pseudostratified ciliated columnar epithelium (A–D), connective tissue (E–H), skeletal muscle
(bottom left), and a multipolar neuron (bottom right).
Question 1
Which of the four primary tissue types is composed of cells that are tightly packed with little extracellular matrix
between them?
A. Epithelial tissue
B. Connective tissue
C. Muscle tissue
D. Nervous tissue
Question 2
A tissue sample shows scattered cells surrounded by a large volume of extracellular matrix containing fibers and
ground substance. This is most consistent with which tissue type?
A. Epithelial tissue
B. Connective tissue
C. Muscle tissue
D. Nervous tissue
Question 3
Which primary tissue type is specialized for generating force through the shortening of its cells?
A. Epithelial tissue
B. Connective tissue
C. Muscle tissue

D. Nervous tissue
Question 4
Which tissue type is specialized for rapid communication using electrical and chemical signals?
A. Epithelial tissue
B. Connective tissue
C. Muscle tissue
D. Nervous tissue
Question 5
Which of the four primary tissue types generally has the greatest capacity for regeneration after injury?
A. Epithelial tissue
B. Cardiac muscle tissue
C. Nervous tissue (CNS neurons)
D. Skeletal muscle tissue
Question 6
A structure/function question: nervous tissue cells have long, branching processes. What is the primary functional
advantage of this shape?
A. It increases surface area for gas exchange
B. It allows cells to receive and transmit signals over long distances
C. It allows the cell to contract and shorten
D. It reduces the metabolic cost of the cell
Question 7
Which statement correctly distinguishes connective tissue from the other three primary tissue types?
A. It is always avascular
B. It contains the least amount of extracellular matrix
C. It is defined largely by the properties of its extracellular matrix rather than its cells alone
D. It cannot contain fibers
Question 8 (True/False)
True or False: All four primary tissue types are found within the integumentary system.
A. True
B. False
Question 9 (True/False)
True or False: Muscle tissue and nervous tissue are both classified as excitable tissues because their plasma
membranes can generate action potentials.
A. True
B. False
Question 10 (Structure/Function)
A tissue sample forms a continuous protective sheet lining an internal cavity, is avascular, and rests on a basement
membrane. Which tissue type does this describe?
A. Epithelial tissue
B. Connective tissue
C. Muscle tissue
