Detailed explanation-1: -This is a sensory pathway carrying pain, temperature, touch, and pressure sensations. It divides into the anterior and lateral spinothalamic tracts. The anterior spinothalamic tract transports crude touch sensations and pressure. The lateral spinothalamic tract is associated with pain and temperature sensations.

Detailed explanation-2: -Thalamus. Located in the central part of the brain, the thalamus receives sensory messages, such as touch, from the body, and sends the messages to the appropriate part of the brain to be interpreted.

Detailed explanation-3: -Our sense of touch is controlled by a huge network of nerve endings and touch receptors in the skin known as the somatosensory system. This system is responsible for all the sensations we feel – cold, hot, smooth, rough, pressure, tickle, itch, pain, vibrations, and more.

Detailed explanation-4: -Touch and pain are aspects of the somatosensory system, which provides our brain with information about our own body (interoception) and properties of the immediate external world (exteroception) (Craig, 2002).
