In an electromyography (EMG) read out, all motor units can look slightly different because:_____.
a. every muscle has a varying number of motor units so they can generate different frequencies.
b. every muscle has a varying number of motor units so they can generate different frequencies.
c. each motor unit can generate a different amount of recruitment.each motor unit can generate a different amount of recruitment.
d. every muscle has one motor unit so they have slightly different frequencies.every muscle has one motor unit so they have slightly different frequencies.
e. each motor unit can innervate a different number of muscle fibers.each motor unit can innervate a different number of muscle fibers.

Electromyography (EMG) is a diagnostic procedure used to measure the response of muscles and nerves to electrical activity. A motor unit is composed of one motor neuron and muscle fibers it innervates. The number of muscle fibers in each motor unit can vary among different muscles and even among motor units within the same muscle. Each motor unit is known to innervate a variable number of muscle fibers, but each single muscle fiber is innervated by only one motor.

An electromyography (EMG) read out has all motor units looking different

because

Every muscle has a varying number of motor units so they can

generate different frequencies

Each motor unit can innervate a different number of muscle fibers.

Electromyography (EMG) is used in diagnostics for measuring the

relationship between muscles and nerves through responses to electrical

activity.

The body has muscles with no constant number of motor units as it varies.

Each motor unit also supply nerves to different number of muscle fibers

which explains the difference in motor units during electromyography.
