Pain pathway | Pain physiology | Pain suppression system | Gate control theory | Neurophysiology

I discuss the pain pathway/physiology under the following headings
1. Definition of pain
2. Types of pain
3. Types of pain fibers
4. Types of pain pathways - course & termination
5. Pain suppression system/ Analgesia system

It's actually medial side only...for the simplicity of diagram, it's put up on lateral, just to show clearly the course ....thanks a lot for pointing it out. The first diagram is from guyton.

[@Prasath-v3q]

A delta fibers... previously u said it occupies the medial side (7.10) but the diagram depicts it on the lateral side... I verified gk pal..even there it is the same diagram???????

[@Dr.Raghu-simplified_classes]

It's medial itself. The first diagram is from Guyton. 2 nd i took for ease of explanation...it's from GK pal. Apologies for the confusion.

[@harshakumarragunta558]

The image at 7:06 is bit confusing,the fibres actually go into anterior horn on the opposite side but the picture shows it as it's going in dorsal horn :)

[@kaleswarimanik9073]

Thank u so much sir ❤ very good explanation 👏🏻

[@Dr.Raghu-simplified_classes]

[@fsiddiqui678]

to start with
Ad fibres were medial
and C were lateral in the spinal cord , then at what point does the arrangement change ? as in the next diagram the arrangemnt is reversed .

Sir, second order of neospinothalamic fibers occupy the lateral spinothalamic tract

[@Dr.Raghu-simplified_classes]

Hi Gowtham, anterolateral means anterior and lateral spinothalamic tract. Guyton 12th edition page 585 " cross immediately to the opposite side of cord and then pass to brain in the anterolateral columns"

Sir can u plz make a video on reflexes nd muscle spindle

[@abhinandms3268]

Sir one doubt, in first diagram fibres entering the spinal cord through dorsal horn amd leaving through opposite side dorsal horn but in second diagram fibres entering through dorsal horn and leaving through ventral horn ,can you pls make it clear sir.

[@Dr.Raghu-simplified_classes]

Fibers cross over to opposite site and lie in lateral white funiculus. They join the lateral spinothalamic tract....they have to cross the grey matter ...and lie in lateral white funiculus. And then ascend upwards in lateral white funiculus. That's y these are referred to as lateral spinothalamic tracts .

Figure shows anterolateral pathway in dorsal position of spinal cord. 7 minutes 37 seconds

[@Dr.Raghu-simplified_classes]

Hi thank you for pointing it. That's the diagram from a respected book "Guyton" It's to understand the level of termination of first order neurons and relationship of slow and fast fibers. I know once the fibers sweep to opposite side they should lie in anterior and lateral white funiculus. 😊
