BIO 161 PSU EXAM 4
1. What are the three types of skeletal, cardiac, smooth
muscle tissue?
2. What are some characteristics -Voluntary
of skeletal muscle? - Striated
- Multinucleate
- Attached to bone or fascia (connective tissue)
3. What are some characteristics - Involuntary
of cardiac muscle? - Striated
- Mononucleate
- Autorhythmic (cells can self-regulate contraction)
4. What are some characteristics - Involuntary
of smooth muscle? - Non-striated
- Mononucleate
5. What are the 5 properties of excitability, conductivity, contractility, extensibility, elasticity
muscle tissue?
6. What is excitability? respond to chemicals released from motor neurons
7. What is conductivity? ability to propagate electrical signals over membrane
8. What is contractility? ability to shorten and generate force
9. What is extensibility? ability to be stretched without damaging the tissue
10. What is elasticity? ability to return to original shape after being stretched
11. What is formed by a group of Muscle
fascicles?
12. Fascicle

, BIO 161 PSU EXAM 4
What is formed by a group of
muscle fibers?
13. What is formed by a group of Muscle fibers
myofibrils?
14. What do myofibrils contain? bundles of protein filaments, organized into sarcomeres
15. What are three functions of -Protects muscle cells
connective tissue? -Reduces friction
-Creates space for extracellular fluid
16. What are the three layers of Epimysium, Perimysium, Endomysium
connective tissue?
17. What is the main character- Covers entire muscle
istic of epimysium connective
tissue?
18. What is the main characteris- Covers fascicles
tic of Perimysium connective
tissue?
19. What is the main characteris- Covers muscle fibers
tic of Endomysium connective
tissue?
20. What is the most common Muscle to bone/indirect
muscle connection?
21. What is indirect muscle con- When collagen fibers of epimysium form strong fibrous tendon
nection? (dense regular connective tissue) that merges into periosteum
(outer covering of bone)
