The mechanosensory system Flashcards
1
Q
The cutaneous/subcutaneous system
A
Processes all tactile info. Possible due to different receptors in the skin. More sensitive areas have higher density of these receptors and smaller fields, creating more precise experience.
2
Q
Route of stimulus
A
Dorsal root ganglion - Spinal cord - thalamus - ventral posterior nuclear complex 0 primary somatosensory cortex (S1)
3
Q
Nociceptive system
A
Perceives pain and temperature with nociceptors in the skin. (placebo effect; creates same activation to alleviate pain. Inhibited by naloxone)
4
Q
Propioceptive system
A
self movement and body positioning
5
Q
Vestibular system
A
Acceleration & deceleration of the body, balance
6
Q
Ventral posterior nuclear complex
A
In the thalamus. Axons feed it to the S1(parietal lobe)
