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).
What else can I help you with?
Which of the sensory functions involves neurons in the posterior root ganglia?
Somatic sensory functions involve neurons in the posterior root ganglia. These neurons are responsible for transmitting information such as touch, pressure, pain, and temperature from the body to the central nervous system.
Do neurons in your brain actually touch each other when receiving messages?
no. they do not.
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.
Does sensory neurons for touch also carries pain impulses?
Yes, sensory neurons for touch can also carry pain impulses when there is tissue damage or injury. These neurons are capable of responding to various stimuli, including pain signals, and transmit this information to the brain for processing.
What is non-nociceptors?
Sensory neurons that respond to light touch and light temperature but not pain.
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)

Neurons dectecting stimuli in the skin and eyes are?
In the skin, neurons that detect stimuli are called mechanoreceptors for touch, nociceptors for pain, and thermoreceptors for temperature. In the eyes, neurons that detect light stimuli are called photoreceptors, specifically rods and cones located in the retina.
What type of neurone carry electrical signal to the brain?
Afferent neurons (also called sensory neurons) carry signals to the central nervous system and the brain. Efferent neurons (also called motor neurons) carry signals from the brain.
Neurons that detect stimuli in the environment are known as?
Sensory (afferent) neurons
Why are sensory neurons important in the skin?
Sensory neurons in the skin play a crucial role in detecting and transmitting various sensory information such as touch, temperature, and pain to the brain. This helps us navigate our environment, feel pain to protect ourselves from harm, and maintain a sense of touch in our daily activities.
