Visceral Sensory Pathways

These flashcards cover key concepts related to visceral sensory pathways, their neurons, and centers that process sensory information from visceral organs.

Visceral Sensory Pathways

Pathways that transmit information received from interoceptors of visceral organs and tissues.

First-order neurons

Neurons that transmit sensory information from interoceptors to second-order neurons.

Spinothalamic pathway

A pathway for transmitting sensory signals related to pain and temperature.

Solitary nucleus of the medulla oblongata

A nucleus that processes sensory information from the visceral organs.

Respiratory center

Specific brain center that regulates respiration based on sensory input.

Cardiovascular center

Brain center that controls cardiovascular functions in response to visceral sensory information.

Reticular formation

A network in the brain that processes arousal and attention influenced by visceral sensory information.

Third-order neurons

These neurons are not involved in visceral sensory pathways, as the information does not reach the primary somatosensory cortex.

Conscious awareness of visceral sensations

Visceral sensory information does not lead to conscious awareness as it does not reach the primary somatosensory cortex.
