Central temperature receptors keep track of the core temperature and are located
In the hypothalamus
Pain receptors =
Nociceptors
The first step of nociception, conversion of stimulus into nerve impulse
Transduction
The second step of nociception, nerve impulses move up the sensory nerve fibers to the spinal cord
Transmission
Third step of nociception, changing of the sensory nerve impulses which can influence the information the brain receives, where that is to amplify or suppress an impulse
Modulation
The last step of nociception, happens in the brain when it is conscious of the impulse
Perception
The sense of body position and movement
Proprioception
Sense of taste =
Gustatory sense
Sense of smell =
Olfactory
