Types of Muscles
This muscle is found in the walls of internal organs and is not striated
What is Smooth muscle?
Which protein filament is responsible for pulling on actin during muscle contraction?
What is Myosin?
What muscle is the prime mover for dorsiflexion of the foot?
What is the Tibialis anterior?
This muscle is found in the heart and is known for its intercalated discs
What is Cardiac muscle?
What is required for the myosin heads to detach from actin and reset during the contraction cycle?
What is ATP?
The biceps brachii is located on the front of the upper arm. What is its primary function?
What is Flexion?
This muscle type has fibers that can contract quickly and strongly and is under voluntary control.
What is Skeletal muscle?
What is the name of the theory that explains how muscle contraction occurs when myosin pulls actin filaments?
What is the Sliding filament theory?
This muscle type is both striated and involuntary and is responsible for pumping blood throughout the body.
What is Cardiac muscle?
Which ions are essential for exposing the active site on actin so that myosin can bind during contraction?
What are Calcium ions?
This muscle tissue is under involuntary control and exhibits slow, sustained contractions.
What is Smooth muscle?
During muscle contraction, calcium ions are released from the sarcoplasmic reticulum. What role do calcium ions play in muscle contraction?
What is calcium ions bind to troponin?
