No, nerves do not send signals. They transmit signals produced by receptors or the brain or spinal cord.
The body uses a complex network of nerve cells called neurons to send electrical signals. These signals travel along the neurons and across the synapses to communicate with other cells in the body, allowing for coordination and control of different functions.

Some guys do send signals. Others do not. It really depends on the guy.
Neurons send signals to other neurons, muscles, and glands in the human body.
send signals
Radio frequency signals.
Usually nerves have good capacity to send signals. These signals are send by depolarization waves across the nerve fibers. For re polarization of the nerves, energy is required and if impulses has to be sent more repeatedly than energy can be generated by cells, there will nerve fatigue, for example after an attack of Fit.(Seizer attack.)
