What else can I help you with?
In motor unit summation how many motor units are required to lift weight of 160 and 80?
The amount of motor units that is needed to lift 160 pounds will be greater that the number required when lifting 80 pounds. This is due to the nervous system reading the situation and determining the number of units required. The smaller the muscle, the more delicate the control can be.
What do you call the increase in the number of motor units activated when the intensity of stimulation increases?
The increase in the number of motor units activated when the intensity of stimulation increases is called recruitment. It allows the body to generate more force by involving additional motor units to contract muscle fibers.
When holding an object does the number of motor units remain the same and are the same units used for the duration of holding the object?
The number of motor units involved in holding an object can vary depending on the weight and complexity of the task. Different motor units may be recruited as needed to maintain force and control. Some motor units may be more fatigable and switch during sustained tasks, but this can depend on the individual and the specific task.
Which muscles are used more with wide arm push ups triceps or biceps?
Biceps
What is 'motor march' in nerve injury?
progressive regeneration or reinnervation of the more proximal motor units during recovery ..seen in case of axonotomesis
When a muscle is stimulated do all motor units fire why or why not?
When a muscle is stimulated not all motor units in the nerve are fired. More muscle fibers are stimulated, however and smaller nerves are stimulated before larger ones.
What consists of a somatic motor neuron plus all the skeletal muscle fibers it stimulates?
A motor unit consists of a somatic motor neuron and all the skeletal muscle fibers it innervates. When the motor neuron fires an action potential, all the muscle fibers in its motor unit contract simultaneously. Motor units vary in size depending on the precision of movement required, with smaller units needed for fine control and larger units for more powerful movements.
What process must occur in the muscle to increase tension so you can pick up a heavier object?
To pick up a heavier object, the muscle fibers must recruit more motor units to generate more force. This is known as the recruitment of motor units. Additionally, there must be an increase in the frequency of motor unit activation to enhance muscle tension and produce more force.
What are agnostic muscle pairs?
Agnostic muscle pairs are muscle groups that work together in a way that they can function independently of each other. They are not reliant on each other during movement, allowing for more flexibility and movement efficiency. Examples include the biceps and triceps in the arms, or the hamstrings and quadriceps in the legs.
What are the muscles of knee?
The main muscles of the knee are the quadriceps (4 muscles which straighten the knee) and the hamstrings (3 muscles that bend the knee). Quadricep Muscles: Rectus Femoris, Vastus Intermedius, Vastus Medialis, Vastus Lateralis Hamstring Muscles: Semimembranosus, Semitendonosus, Biceps Femoris The other muscles around the knee are Popliteus (at the back of the knee) and the calf muscles (gastrocnemius and soleus)
Why does varying stimulus strength affects the twitch force?
Varying stimulus strength affects twitch force because it determines the number of motor units that are recruited to contract the muscle fibers. As the stimulus strength increases, more motor units are recruited, leading to greater force production. Conversely, lower stimulus strength recruits fewer motor units and results in weaker contractions.
How do you spell biceps?
That is the correct spelling of the term "biceps" (muscles of the upper arm).
