MICROANATOMY

Detailed explanation-1: -The lateral spinothalamic tract focuses on transmission of the pain and temperature sensation, while the anterior spinothalamic tract carries information related to the crude touch and firm pressure sensation towards the thalamus in the brain.

Detailed explanation-2: -The anterior spinothalamic tract transports crude touch sensations and pressure. The lateral spinothalamic tract is associated with pain and temperature sensations. Peripheral sensory fibers are first-order neurons.

Detailed explanation-3: -The spinothalamic tract pathway is an imperative sensory pathway in human survival because it enables one to move away from noxious stimuli by carrying pain and temperature information from the skin to the thalamus where it is processed and transmitted to the primary sensory cortex.

Detailed explanation-4: -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-5: -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.
