Which of the following is the only type of muscle tissue which is under voluntary control?
Skeletal muscle
Static muscle
Cardiac muscle
Smooth muscle
What is the chief function of T tubules?
They allow electrical impulses to travel deep into the cell.
They store the calcium ions necessary for muscle contraction.
They contain myofilaments necessary for muscle contraction.
They store glycogen and oxygen.
In order for muscle contraction to occur, the muscle fiber requires calcium, as well as this substance which provides the cell with energy:
ATP
Epinephrine
Bicarbonate
Lipase
Most muscles remain continually in a state of:
Twitch
Incomplete Tetanus
Complete Tetanus
Treppe
The phenomenon in which each successive twitch contracts more forcefully than the previous one is known as:
Threshold
Incomplete tetatus
Complete tetanus
Treppe
Bundles of muscle fibers within a skeletal muscle are known as:
Fasicles
Motor Units
Sarcomeres
Sarcolemmas
When the muscle fiber receives a stimulus that is at or above the threshold, it responds with a single, brief contraction called a:
Treppe
Twitch
Tremble
Trope
These muscles are the main muscle in a group which is responsible for triggering a specific type of movement:
Agonist
Synergist
Antagonist
Prime Mover
Within a group, the muscle that opposed the action of the prime mover is known as the:
Synergist
Antagonist
Flexor
Abductor
The end of the muscle that attaches to the more movable bone is known as the:
Origin
Insertion
Belly
Tendon
In this type of muscle attachment, muscle fibers merge with the periosteum of the bone, forming a strong attachment.
Direct attachment
Indirect attachment
Synovial attachment
Fibrous attachment
A motor neuron and all the muscle fibers it stimulates are known as a:
Fascicle
Sarcomere
Sarcoplasm
Motor unit
