Every muscle (no matter which muscle, even a single muscle fibre-unit) have several motor neurons.
The quadriceps has 4 units while the biceps has 2.
QUADRICEPS
Biceps
progressive regeneration or reinnervation of the more proximal motor units during recovery ..seen in case of axonotomesis
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.
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.
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)
The quadriceps group of muscles. Rectus Femoris more specifically.
That is the correct spelling of the term "biceps" (muscles of the upper arm).
If the subject uses their dominant forearm more, that forearm can attain more force. The greater the force, the greater the degree of activation of motor units. However, in most cases, the non-dominant forearm generally can attain more force.
mcc - motor control center or motor control console. A motor control center (MCC) is an assembly of one or more enclosed sections having a common power bus and principally containing motor control units
One that isn't needed for precise movement. Muscles that need precise control have motor units with more muscle fibers.
Triple h has big biceps. its biceps size is 32 inches. he has his name in guineas world records 2001.he is also known as big biceps(trippie). he also defeat khali in arm wrestling who,s biceps size is 30 inches. only 2 inches less. if you have more size in biceps than you will win
If these muscles are weak or injured, there can be more risk of knee injuries.
