Neural impulses from touch first travel to the spinal cord, where they are relayed to the brain. Specifically, they ascend through pathways such as the dorsal column-medial lemniscal pathway before reaching the thalamus. From the thalamus, the signals are then directed to the primary somatosensory cortex in the parietal lobe, where the perception of touch occurs.
What else can I help you with?
What stimulates sensory impulses at receptors?
Sensory impulses at receptors are typically stimulated by specific environmental stimuli such as light, sound, touch, temperature, or chemicals. These stimuli activate specialized receptors on sensory neurons, which then generate neural signals that are transmitted to the brain for further processing and interpretation.
What form sensory impulses?
Sensory impulses are typically in the form of electrical signals that travel along nerve fibers from sensory receptors to the brain or spinal cord. These impulses carry information about sensations such as touch, temperature, pain, and pressure. The brain then processes these impulses to generate a conscious perception of the sensory input.
How does your sense of touch get stimulated?
Your sense of touch gets stimulated when nerve endings in your skin detect pressure, temperature, or vibration. These nerve impulses then travel to your brain, where they are processed and interpreted as different sensations such as heat, cold, pain, or texture.
What is the neural pathway of touch?
The neural pathway of touch involves sensory receptors in the skin detecting a stimulus, which sends signals through sensory nerves to the spinal cord. In the spinal cord, the signals are relayed to the brainstem and then to the thalamus. From the thalamus, the signals are further processed and sent to the somatosensory cortex in the brain, where they are interpreted as touch.
What lobe are the impulses in the skin received?
Impulses from the skin are received in the parietal lobe of the brain. The parietal lobe is responsible for processing sensory information such as touch, temperature, and pain.

What sends impulses to brain?
sensory neurons
How fast do nerves impulses travel?
Nerve impulses travel through nerve fibers via a action potential and the speed at which the impulse travels depends on the type of nerve fibre. This can range from 100m/s in the case of touch to 20-30 m/s when you're thinking.
How does your sense of touch get stimulated?
Your sense of touch gets stimulated when nerve endings in your skin detect pressure, temperature, or vibration. These nerve impulses then travel to your brain, where they are processed and interpreted as different sensations such as heat, cold, pain, or texture.
What phenomenon explains why a light touch feels different than a touch applied with more pressure?
frequency of impulses

Impulses from the skin are received in the parietal lobe of the brain. The parietal lobe is responsible for processing sensory information such as touch, temperature, and pain.
What tract conveys nerve impulses for crude touch and pressure?
spinothalamic, it is a somatosensory pathway
Sensory impulses transmitted over the facial glossopharyngeal and vagus nerves are involved in the sensation of?
The taste and touch sensation
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 lobe receives and interprets impulses from sensory receptors in the tongue and muscles?
The parietal lobe is responsible for receiving and interpreting impulses from sensory receptors in the tongue and muscles. It plays a role in processing sensations related to touch, temperature, and pain.
