Nervous tissue is specialized for receiving stimuli and conducting impulses. Neurons are the primary cells of nervous tissue that are responsible for transmitting electrical signals throughout the body.
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.
Nociceptors are responsible for transmitting pain impulses. These are specialized nerve endings that detect tissue damage or potentially harmful stimuli and send signals to the brain to alert the body of pain.
Structures adapted to convert stimuli into nerve impulses are called receptors. Receptors can be specialized cells or structures within the body that detect a specific type of stimulus, such as light, sound, pressure, or chemicals, and then convert that stimulus into electrical signals that can be interpreted by the nervous system.
The two major cell populations specialized for this function are neurons, which receive and transmit electrical signals, and neuroglia, which serve supporting roles in maintaining the environment for proper neuronal function and communication. Together, they form the cellular framework of the nervous system, responsible for receiving stimuli and conducting waves throughout the body.
Neurons receive stimuli from the environment or other cells, which triggers the formation of electrical impulses that travel along the neuron's axon. These impulses then allow for communication between different parts of the body or with other neurons.

these are wire-like projections from the main cell body, which are often further branched and carry impulses to the cell body. theses are called dendrites.
The tissues responsible for sensing stimuli are called sensory receptors. These receptors are specialized cells that detect changes in the environment, such as pressure, temperature, and chemicals, and convert them into electrical signals that can be interpreted by the brain. Various types of sensory receptors are found throughout the body, including in the skin, eyes, ears, and internal organs.
