What size are the motor units in the eye?
The motor units of the eye are small. Small motor units are found where precise movements are needed as in the muscles of the eye.
How are motor units recruited?
Motor units can be recruited when the activation of the motor neuron activates all muscles fibers in the motor unit. The increase in tension occurs in steps proportional to the size of the motor unit.
What motor unit has the fewest muscle fibers?
One that isn't needed for precise movement. Muscles that need precise control have motor units with more muscle fibers.
To accomplish a strong contraction are stimulated at a rapid rate?
many motor units are stimulated
What part of nervous system controls voluntary movements thoughts and registration of incoming information?
The muscle fibers are functionally organized as motor units. A motor unit consists of a single motor neuron and all of the muscle fibers it innervates.Whole muscles exhibit characteristics that are more complex than those of individual muscle fibers or motor units. Instead of responding in an all-or-none fashion, whole muscles respond to stimuli in a graded fashion, which means that the strength of the contractions can range from weak to strong.
How do you convert 3phase 1hp motor into units?
Into units of what?
To accomplish strong contraction what is stimulated at a rapid rate?
Many Motor Units
Which of the following would be recruited later in muscle stimulation when contractile strength increases?
Um are you an idiot, you never put choices! A) large motor units with small, highly excitable neurons B) motor units with the longest muscle fibers C) many small motor units with the ability to stimulate other motor units D) motor units with larger, less excitable neurons
The contractile units of skeletal muscles are?
Myofibrils!
Contractile units of skeletal muscles are?
myofibrils
Is multiunit smooth muscle composed of sheets of muscle cells?
Within the eye in both the iris and ciliary muscle, composing the arrector pili muscles in the skin, the wall of larger air passageways within the respiratory system, and the walls of larger arteries.
Which nervous system controls the voluntary function of the limbs and the sense organs?
The muscle fibers are functionally organized as motor units. A motor unit consists of a single motor neuron and all of the muscle fibers it innervates.Whole muscles exhibit characteristics that are more complex than those of individual muscle fibers or motor units. Instead of responding in an all-or-none fashion, whole muscles respond to stimuli in a graded fashion, which means that the strength of the contractions can range from weak to strong.
