Actually all cells can send and receive signals. For example every cell has a CD95(FASr) which receives signals from natural killer cells or T cells and results in cell death. Also all cells send signals through cell membrane receptors to neighboring cells. These signals prevent neighboring cell colonies from growing too big.(The lack of these signals is one of the problems with certain cancer cells)
Neurotransmitters are chemicals that send messages from one cell to another.
Yes they do send out signals
Axons send signals.
No, nerves do not send signals. They transmit signals produced by receptors or the brain or spinal cord.
The dendrites collect information from other cells (afferent) or send information to other cells (efferent). The afferent dentrites are stimulated by chmicals from sensory cells. The efferent dentrites send chemical signals to other cells.
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
The dendrites of the nerve cell carry signals toward the cell body where the nucleus is located. Dendrites receive signals from other nerve cells or sensory receptors and transmit these signals to the cell body for processing.
They carry electrical signals around the body. Parts called dendrites on one end of the cell pick up a signal from a connected neuron through the synaptic cleft, and send it down the length of the cell by means of sodium potassium pumps and Nodes of Ranvier, eventually reaching the other end of the cell, and being transfered across the synapse to another neuron.
Radio frequency signals.
