Verified Answers | Latest Update 2026/2027
Question: What are the three types of muscle tissue?
Answer: Skeletal, Cardiac, and Smooth
Question: What are characteristics of skeletal muscle?
Answer: Striated, voluntary, multinucleated, somatic nervous system control
Question: What are characteristics of smooth muscle?
Answer: Non-striated, involuntary, uninucleated, autonomic nervous control
Question: What are characteristics of cardiac muscle?
Answer: Striated, branching, uninucleated, involuntary, autonomic nervous control,
intercalated
discs (gap junctions)
Question: What is the thick filament?
Answer: Myosin
Question: What is the thin filament?
Answer: Actin
Question: What are mediating proteins of muscle tissue?
Answer: Troponin and Tropomyosin
Question: What does Calcium bind to?
Answer: Troponin
Question: Where does Calcium come from?
Answer: Sarcoplasmic Reticulum
Question: When Calcium binds to Troponin, what happens?
Answer: There is a confirmational change wherein Troponin moves Tropomyosin away so that
Myosin can bind to Actin
Question: What are characteristics of all muscles?
Answer: Electrical excitability, extensibility, elasticity, contractility
, Question: What are the three meninges from outer to inner, including spaces?
Answer: Dura Mater, Arachnoid Mater, Subarachnoid Space (where CSF is found), Pia Mater
(directly attached to spinal cord and brain)
Question: What is the filum terminale?
Answer: An extension of the Pia Mater which attaches the spinal cord to coccygeal segment
Question: What is an isometric contraction?
Answer: Length of muscle does not change, but tension does
Question: What is an isotonic contraction?
Answer: Length of muscle changes, but tension does not
Question: What is a concentric isotonic contraction?
Answer: Muscle shortens
Question: What is an eccentric isotonic contraction?
Answer: Muscle lengthens
Question: What is an agonist?
Answer: Prime mover
Question: What is an antagonist?
Answer: Opposes action of the prime mover
Question: What is a synergist?
Answer: An "assistant" or "helper" muscle to the agonist
Question: What is a fixator?
Answer: Stabilizes muscles
Question: What is the origin?
Answer: Point of origin for a muscle with NO movement
Question: What is the insertion
Answer: Where the muscle inserts, non-stable end where most of the movement associated
with
the muscle is performed
