Somatic motor neurons are used to transmit motor signals to muscles. For example, a somatic motor neuron carries a signal from y
our spinal cord to your biceps brachii so that you can flex your arm at the elbow. In this example, what is the correct sequence of neuronal structures that this signal would travel through in the motor neuron?
Neurons are the structural and functional unit of the nervous system. The neurons helps in the transmission of nerve impulse in the body. Two main types of neuron are somatic neuron and motor neuron.
The signal is first reach to dendrites. From the dendrites, the signal transmit to the cell body and then to the axon hillock. The signal then transmits to the axon. At the end of neuron the message is transmitted to the synaptic terminal. The nerve impulse finally reaches to the biceps brachii and results in the flexion of the arm at the elbow.
