Muscle Tissue And Muscle Mastication Flashcards
What is the primary function of muscle tissue?
The primary function of muscle tissue is to produce movement.
What are the three types of muscle tissue?
The three types of muscle tissue are skeletal, cardiac, and smooth.
Which type of muscle tissue is striated and voluntary?
Skeletal muscle tissue is striated and voluntary.
Which type of muscle tissue is found in the walls of hollow organs?
Smooth muscle tissue is found in the walls of hollow organs.
Which type of muscle tissue is found in the heart?
Cardiac muscle tissue is found in the heart.
True or False: Smooth muscle tissue is under voluntary control.
False. Smooth muscle tissue is involuntary.
What is the basic functional unit of skeletal muscle?
The basic functional unit of skeletal muscle is the sarcomere.
What is the role of myosin in muscle contraction?
Myosin is a protein that interacts with actin to generate the force of muscle contraction.
What is the neurotransmitter responsible for muscle contraction at the neuromuscular junction?
Acetylcholine is the neurotransmitter responsible for muscle contraction at the neuromuscular junction.
What is the term for the ability of muscle tissue to stretch without being damaged?
The term for the ability of muscle tissue to stretch without being damaged is extensibility.
What is the term for the ability of muscle tissue to return to its original shape after being stretched?
The term for the ability of muscle tissue to return to its original shape after being stretched is elasticity.
Which type of muscle tissue has intercalated discs?
Cardiac muscle tissue has intercalated discs.
What is the specific type of smooth muscle found in blood vessels?
The specific type of smooth muscle found in blood vessels is vascular smooth muscle.
What is the term for the ability of muscle tissue to generate tension and contract?
contractility
What is the term for the connective tissue that surrounds bundles of muscle fibers?
perimysium
What is the term for the connective tissue that surrounds individual muscle fibers?
The connective tissue that surrounds individual muscle fibers is called endomysium.
What is the term for the connective tissue that surrounds the entire muscle?
The connective tissue that surrounds the entire muscle is called epimysium.
What is the term for the point of attachment of a muscle to a bone that remains relatively fixed during contraction?
The point of attachment of a muscle to a bone that remains relatively fixed during contraction is called the origin.
What is the term for the point of attachment of a muscle to a bone that moves during contraction?
The point of attachment of a muscle to a bone that moves during contraction is called the insertion.
What is the term for the type of muscle contraction where the muscle shortens and generates force?
The type of muscle contraction where the muscle shortens and generates force is called concentric contraction.
What is the term for the type of muscle contraction where the muscle lengthens while generating force?
The type of muscle contraction where the muscle lengthens while generating force is called eccentric contraction.
What is the term for the type of muscle contraction where the muscle length remains constant as it generates force?
The type of muscle contraction where the muscle length remains constant as it generates force is called isometric contraction.
All muscle tissue has some degree of elasticity and extensibility, but which type of muscle tissue is capable of the greatest levels of these properties?
A. Cardiac B. Skeletal C. Smooth
C. Smooth
E.g the bladder and the stomach these organs are composed of smooth muscle and can extend/return back to it’s original shape
The action of which muscle is to compress and protrude the lips?
Orbicularis Oris
