The muscles with the highest motor innervation units are typically those involved in gross motor functions, such as the large muscles of the legs, particularly the quadriceps and gastrocnemius. These muscles have a high ratio of muscle fibers to motor neurons, allowing for powerful contractions necessary for activities like running and jumping. In contrast, muscles requiring fine motor control, like those in the hands and eyes, have lower motor unit ratios.
What else can I help you with?
What size are the motor units in the eye?
The motor units in the eye are small and fine, typically containing around 10-20 muscle fibers. These motor units are responsible for controlling the movement of the eye muscles with precision and accuracy.
Motor unit would produce greatest tension eye back hand?
The hand muscles contain motor units that produce the greatest tension, followed by the back muscles and then the eye muscles. This is due to the varying sizes and recruitment patterns of motor units in different muscles throughout the body.
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 part of the body have largest motor unit and smallest?
The largest motor units are found in the lower limbs, particularly in the muscles responsible for powerful and forceful movements like the quadriceps. The smallest motor units are typically found in muscles that require fine motor control and precision, such as the muscles in the hands and fingers.
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.
Are precise movements controlled by small motor units?
Yes, precise movements are controlled by small motor units. Small motor units are composed of fewer muscle fibers and are responsible for fine motor control and intricate movements. These motor units are recruited for tasks that require precision and accuracy.
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
Contractile units of skeletal muscles are?
myofibrils
