No. There is a synaptic cleft between the axon of one neuron and the dendrite of another neuron. At the synapse, a chemical messenger is needed - in order to carry the "message" from one nerve to the next, whereupon electrical transmission once again occurs (via depolarization and then repolarization).

Do neurons in your brain actually touch each other when receiving messages?
no. they do not.
Which of the sensory functions involves neurons in the posterior root ganglia?
touch
What is junction between two neurons?
The synaptic cleft is the space between two neurons, they never actually touch each other.
Do neurons touch each other?
Not exactly; as an impulse moves from one neuron to another it crosses a small space between the neurons called a synapse. The neurons as said to 'not touch' because the cell MEMBRANES of the two neurons do NOT touch, nor merge, nor consequently is there any sharing of cytoplasm between the two neurons. The two neurons ARE, however, HELD TOGETHER at that synapse by small molecules called SYNAPTIC ADHESION MOLECULES, which protrude FROM each neuron into the synaptic cleft or gap and then stick to one another. In this sense, PARTS of neurons do 'touch' PARTS of other neurons, in a MECHANICAL or structural manner, but NOT in an electrical or signal sense. The neural SIGNAL passes through the synaptic cleft or gap via neurotransmitter chemicals which are released by one neuron, diffuse quickly through the gap, and then stimulate a signal in the receiving neuron.
When you touch something what sends a message to your brain?
Your afferent neurons send a message to your brain.
What are the three different kinds of neurons?
Touch, smell, and hearing. (three out of the five senses)
What is non-nociceptors?
Sensory neurons that respond to light touch and light temperature but not pain.
What are the three different kinds of sensory neurons?
Touch, smell, and hearing. (three out of the five senses)
What regulates the body through impulses that come from the environment?
Sensory neurons provide information from the environment to the body. For example, when you touch a hot surface, a sensory neuron informs your body that the temperature near your skin is rising. Motor neurons are the neurons the body uses to react to the environment. For example, if you touch a hot surface, then your body will make your hand move away from that surface by a motor neuron. The action is the result of the motor neurons not the fact you realize it is hot, Motor neurons also send impulses to your muscles. These neurons are called somatic neurons. Another motor neuron is the autonomic neuron. This neuron control your organs and heart. Usually the Vegas nerve controls and divides this power in two ways: sympathetic and parasympathetic
T or f When you touch something hot your nerves produce larger action potentials than if you touch something warm?
False. Neurons always fire the same amount.
Does sensory neurons for touch also carries pain impulses?
yes touch receptors can also feel pain you have to touch or be hurt by something or someone for that impulse to relay back to the brain that, yes, that did hurt or, yes, I am in pain
The two main ways in which neurons are able to react to stimuli are?
The two main ways in which neurons are able to react to stimuli are conduction impulses and communicating with each other. These stimuli can be touch, sound, light, taste, and smell.
