Herein, what is the most distinguishing characteristic of muscle tissue quizlet?
It is composed of multiple cells working together. The glycogen is an insulating layer that helps regulate body temperature. Skeletal muscle is a heavy consumer of energy.
Additionally, which muscle cells have the greatest ability to regenerate? Skeletal muscles have some ability to regenerate and form new muscle tissue, while cardiac muscle cells do not regenerate. However, new research suggests that cardiac stem cells may be coaxed into regenerating cardiac muscles with new medical strategies. Smooth muscle cells have the greatest ability to regenerate.
Also, what are three important characteristics of muscle tissue?
All muscle cells share several properties: contractility, excitability, extensibility, and elasticity:Contractility is the ability of muscle cells to forcefully shorten.
Excitability is the ability to respond to a stimulus, which may be delivered from a motor neuron or a hormone.
Which of the following describes the Suprahyoid muscles?
The suprahyoid muscles are four muscles located above the hyoid bone in the neck. They are the digastric, stylohyoid, geniohyoid, and mylohyoid muscles. They are all pharyngeal muscles, with the exception of the geniohyoid muscle. The digastric is uniquely named for its two bellies.

What is true concerning myelin?
What is true concerning Myelin? fatty substance that helps in transmitting information between neurons. Touch is important to communicate with an infant because: it helps infant develop motor skills. it helps infant develop a sense of its own body.
What do we call a muscle whose contraction is mostly responsible for producing a movement?
Insertion. A muscle whose contraction is chiefly responsible for producing a particular movement is called: A prime mover. Muscles are classified functionally as synergists when: Muscles contract together and are coordinated in affecting a particular movement.
How do three muscle tissue types look similar and different?
The 3 types of muscle tissue are cardiac, smooth, and skeletal. Cardiac muscle cells are located in the walls of the heart, appear striated, and are under involuntary control. Skeletal muscle fibers occur in muscles which are attached to the skeleton. They are striated in appearance and are under voluntary control.
What is the main factor that determines the power of a muscle?
A&P I Chapter 10 Answer Question
the total number of muscle cells available for contraction What is the main factor that determines the power of a muscle?
an agonist What is a muscle that provides the major force for producing a specific movement called?
What controls the force of muscle contraction?
The force of muscle contraction is controlled by multiple motor unit summation or recruitment. Eccentric contractions are more forceful than concentric contractions. A motor neuron and all the muscle cells that it stimulates are referred to as a motor end plate.
Which of the following is a defining characteristic of skeletal muscle?
Four characteristics define skeletal muscle tissue cells: they are voluntary, striated, not branched, and multinucleated. Skeletal muscle tissue is the only muscle tissue under the direct conscious control of the cerebral cortex of the brain, giving it the designation of being voluntary muscle.
What is a factor that affects the velocity and duration of muscle contraction?
muscle fiber size, the number of muscle fibers stimulated, the frequency of stimulation and the degree of muscle stretch, factors that influence velocity of contraction include muscle fiber type, load and the number of motor units contracting.
What is the role of calcium in muscle contraction?
Calcium triggers contraction by reaction with regulatory proteins that in the absence of calcium prevent interaction of actin and myosin. Myosin control can function with pure actin in the absence of tropomyosin. Calcium binding and regulation of molluscan myosins depend on the presence of regulatory light chains.Interested in items for sale? ⬇️

The Stimulus for Muscle Contraction
Muscle contraction occurs always according to the specific stimulus that reaches the muscle. The stimulus comes from mainly the motor neurons and then neurotransmitter passes from the axon terminal to the surface of the muscles. The neuromuscular junction is responsible for providing the signal for the process of contraction of the muscle. The signal is carried from the neural cell to the muscle based on the binding of the neurotransmitter to the receptors present on the muscle cell surface.

True
Curare is a poisonous plant extract. Curare molecules have a chemical structure like the neurotransmitter ACh. Curare can bind to the ACh receptor site on the chemically gated ion channels in the motor end plate. Even though curare will bind to the receptor site it will not open the ion channel and no ions will pass through. What do you think the symptoms of curare poisoning would look like?
Smooth muscles will become stimulated causing quick movement of nutrients through the digestive system.
Muscles will respond too quickly and cause a severe tremor.
Curare will only affect cardiac muscle, causing fibrillations of the heart.
