refractory period
When a muscle is unable to respond to stimuli temporarily it is in which of the following periods when a muscle is unable to respond to stimuli temporarily it is in which of the following periods?
When two stimuli are applied one after another intermediately, muscles contract in response to the first stimuli. Once a muscle fiber receives stimulation to contract, it loses its excitability temporarily and cannot respond for a time. This period when the muscle loses its excitability is called
refractory period
.
When a muscle is unable to respond to stimuli temporarily it is in which of the following periods when a muscle is unable to respond to stimuli temporarily it is in which of the following periods fatigue period refractory period relaxation period latent period?
In physiology, a refractory period is a period of time during which an organ or cell is incapable of repeating a particular action, or (more precisely) the amount of time it takes for an excitable membrane to be ready for a second stimulus once it returns to its resting state following an excitation.
When a muscle is unable to respond to stimuli temporarily it is in which of the following?
| Question Answer | whena muscle is unable to respond to stimuli temporarily it is in which of the following periods? refractory period | what is the role of calcium ions in muscle contration? bind to regulatory sites on troponin to remove contraction inhibition |

Can a muscle respond to a stimulus?
The
muscle responds to stronger stimuli by producing the same force
. In skeletal muscles a motor neuron can innervate many muscle fibers. This is called a motor unit. … One stimulus will affect all of the muscle fibers innervated by a given motor unit.
Which muscle cells have the greatest ability to regenerate?
Smooth cells
have the greatest capacity to regenerate of all the muscle cell types. The smooth muscle cells themselves retain the ability to divide, and can increase in number this way.
Which of the following would act as a stimulus to initiate a muscle contraction?
| Question Answer | List the factors which can act as a stimulus to initiate a muscle contraction hormonal activity neurotransmitters , a change in pit of a muscle | The term aponeurosis refers to: tendons that anchor muscle to connective tissue of selection |

Which of the following is true skeletal muscle lacks?
Skeletal muscle lacks the coarse connective tissue sheaths that are found in
smooth muscle
. Skeletal muscle cells have one nucleus, but smooth muscle cells are multinucleated. Skeletal muscle fibers contain sarcomeres; smooth muscle fibers do not.
What controls the force of muscle contraction?
The force of muscle contraction is controlled by
multiple motor unit summation or recruitment
. … A contraction in which the muscle does not shorten but its tension increases is called isometric. TRUE. During isotonic contraction, the heavier the load, the faster the velocity of contraction.
What is the most distinguishing characteristic of muscle tissue?
What is the most distinguishing characteristic of muscle tissue?
Its ability to transform chemical energy into mechanical energy
.
Which of the following is NOT a muscle function?
The following is not a major function of muscle tissue: c) storage of information. The main function of muscle tissue is the body is movement, both voluntary and involuntary. Muscle tissue is made up of cells that are specialized to contract, or shorten, generating heat.
What is the cause of rigor mortis?
Rigor mortis is due to
a biochemical change in the muscles that occurs several hours after death
, though the time of its onset after death depends on the ambient temperature. The biochemical basis of rigor mortis is hydrolysis in muscle of ATP, the energy source required for movement.
What is a muscle cell membrane called?
The muscle cell membrane is called
the sarcolemma
and the cytoplasm, the sarcoplasm.
Which best describes the ability of a muscle to shorten after being stretched?
Contractility
is the ability of a muscle to shorten forcibly when adequately stimulated. … Elasticity is the ability of a muscle fiber to recoil and resume its resting length after being stretched.
What is the ability to respond to a stimulus called?
In physiology, a stimulus is a detectable change in the physical or chemical structure of an organism’s internal or external environment. The ability of an organism or organ to detect external stimuli, so that an appropriate reaction can be made, is called
sensitivity (excitability)
.
Which muscles receive and respond to stimulation?
(
excitability
) muscles receive and respond to stimulation.
