Nociceptive signals are transmitted primarily to which of the following?
Nucleus caudalis
Limbic system
Reticular system
Superior cervical ganglion
Trigeminal Nucleus caudalis is an important site for processing orofacial nociceptive input. After activation of C and A delta fibres, they transmit nociceptive signals primarily via trigeminal nerves to Trigeminal Nucleus caudalis. It is also called as medullary dorsal horn as it has similar anatomical resemblance to spinal dorsal horn.
