Muscle tissue has four main properties:
Excitability (ability to respond to stimuli)
Contractibility (ability to contract)
Extensibility (ability to be stretched without tearing)
Elasticity (ability to return to its normal shape).

What special feature of smooth muscle allows it to stretch without immediately resulting in a strong contraction?
stress-relaxation responsestress-relaxation response
In response to a muscle being overstretched a muscle spindle generates a somatic spinal reflex that ultimately causes what response?
Both contaction of the agonist muscle and relaxation of the antagonist muscle
What is the functional unit of a muscle called?
Sarcomere
What is the functional unit of muscle?
sarcomeres
What test makes use of a special hammer?
The test that makes use of a special hammer is the reflex hammer test. It is used to check the reflexes in various parts of the body by tapping the tendon with the hammer to observe the muscle's response.
Do smooth or skeletal muscle form a functional syncytium?
visceral smooth muscles cells function together as ONE (functional syncytium) multiunit smooth muscle act independently.
What is a functional syncytium?
Cardiac muscle cells are mechanically, chemically, and electrically connected to one another, thus, the entire tissue resembles a single, enormous muscle cell. For this reason, cardiac muscle has been called a functional syncytium. This is also true of smooth muscle.
The structural and functional unit of skeleton muscle is called?
sarcomere
What is the relationship between amplitude of muscle response and voltage of stimulus applied?
The relationship between the amplitude of muscle response and the voltage of the stimulus is generally linear. As the voltage of the stimulus increases, the muscle response increases in amplitude up to a certain point. Beyond that point, further increases in voltage may not significantly increase the muscle response amplitude or could lead to muscle fatigue or damage.
The smallest functional unit of the muscle fiber?
The smallest functional unit of a muscle fiber is the sarcomere. Sarcomeres are composed of actin and myosin filaments arranged in a repeating pattern, allowing for muscle contraction and relaxation to occur. They are responsible for the striated appearance of skeletal muscle under a microscope.
What is the premotor phase of reaction time?
The time it takes from recognizing a stimulus to the initiation of a muscle response (the muscle response can be recorded using an EMG).
What type of muscle whose functional characteristics most closely resemble those of an individual muscle fiber?
Parallel
