PATHOLOGY

Detailed explanation-1: -Thalamus: The thalamus is the relay center of the brain. It receives afferent impulses from sensory receptors located throughout the body and processes the information for distribution to the appropriate cortical area. It is also responsible for regulating consciousness and sleep.

Detailed explanation-2: -All sensory signals begin as receptor potentials. These potentials lead to a release of a neurotransmitter that excites its corresponding nerve to send information to the brain.

Detailed explanation-3: -The somatosensory systems also monitor the temperature of the body, external objects and environment, and provide information about painful, itchy and tickling stimuli. The sensory information processed by the somatosensory systems travels along different anatomical pathways depending on the information carried.

Detailed explanation-4: -Sensory receptors are either specialized cells associated with sensory neurons or the specialized ends of sensory neurons that are a part of the peripheral nervous system, and they are used to receive information about the environment (internal or external).
