◉ What are characteristics of skeletal muscle?
Answer: Striated, voluntary, multinucleated, somatic nervous system
control
◉ What are characteristics of smooth muscle?
Answer: Non-striated, involuntary, uninucleated, autonomic nervous
control
◉ What are characteristics of cardiac muscle?
Answer: Striated, branching, uninucleated, involuntary, autonomic
nervous control, intercalated discs (gap junctions)
◉ What is the thick filament?
Answer: Myosin
◉ What is the thin filament?
Answer: Actin
,◉ What are mediating proteins of muscle tissue?
Answer: Troponin and Tropomyosin
◉ What does Calcium bind to?
Answer: Troponin
◉ Where does Calcium come from?
Answer: Sarcoplasmic Reticulum
◉ 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
◉ What are characteristics of all muscles?
Answer: Electrical excitability, extensibility, elasticity, contractility
◉ 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)
, ◉ What is the filum terminale?
Answer: An extension of the Pia Mater which attaches the spinal
cord to coccygeal segment
◉ What is an isometric contraction?
Answer: Length of muscle does not change, but tension does
◉ What is an isotonic contraction?
Answer: Length of muscle changes, but tension does not
◉ What is a concentric isotonic contraction?
Answer: Muscle shortens
◉ What is an eccentric isotonic contraction?
Answer: Muscle lengthens
◉ What is an agonist?
Answer: Prime mover
◉ What is an antagonist?
Answer: Opposes action of the prime mover
