, Sensory Systems

Question 1.
What Is Spinothalamic Pathway?
ANS.
Spinothalamic Pathway Is A Major Sensory Tract In The Central Nervous System That
Transmits Pain, Temperature, Itch, And Crude Touch From The Body To The Brain.
The Spinothalamic Pathway Carries Sensory Information, Particularly Pain, Temperature,
Itch, And Crude Touch, From The Body Toward The Brain For Processing.


Question 2.
Using Below Image




A. Label Parts A, B, C, D, E, Of Ascending Pathways: Spinothalamic Tracts


Choices:

,-First Order Neuron
-Second Order Neuron
-Spinothalamic Tract
-Thalamus
-Third Order Neuron
ANS.
A- First Order Neuron
B- Second Order Neuron
C- Spinothalamic Tract
D- Thalamus
E- Third Order Neuron
Explanation:
The Spinothalamic Pathway Uses First-, Second-, And Third-Order Neurons To Carry
Sensory Information From The Body Through The Spinal Cord And Thalamus To The
Primary Somatosensory Cortex.


B. Name The Pathway Labeled 1,2,3,4,5,6
ANS.
1- First Order Neuron Carrying Stimulus Enters Posterior Horn
2- First Order Neuron Synapses On Second Order Neuron In Posterior Horn
3- Second Order Neuron Decussates And Travels In The Spinothalamic Tract
4- Spinothalamic Tract Passes Through The Medulla Oblongata, Pons, And Midbrain
5- Second Order Neuron Synapses On The Third Order Neuron In The Thalamus
6- Third Order Neuron Synapses On Interneurons In The Primary Somatosensory Cortex
Explanation:
The Pathway Begins With The First-Order Neuron Entering The Posterior Horn. The
Second-Order Neuron Crosses Over And Ascends Through The Spinothalamic Tract To
The Thalamus, Where It Synapses With The Third-Order Neuron. The Third-Order
Neuron Then Carries The Information To The Primary Somatosensory Cortex.


Question 3.

,Using Below Image Of Brain, Name Parts Labeled: E, F, G, H, I And Match With
Their Roles.




Choices
- Cingulate Cortex
- Hypothalamus
- Interthalamic Adhesion
- Entorhinal Cortex
- Corpus Callosum
Roles
A. Connects The Two Cerebral Hemispheres And Allows Communication Between Them
B. Receives Input From Cerebral Cortex And Projects To The Hippocampus
C. Connects The Two Thalami Across The Third Ventricle
D. Involved In Emotional Processing And Aspects Of Motivation And Behavior
E. Helps Regulate Homeostasis And Functions Such As Temperature, Hunger, Thirst,
And Endocrine Activity
ANS. AND CORRECT MATCH
E- Cingulate Cortex — D. Involved In Emotional Processing And Aspects Of Motivation
And Behavior
F- Hypothalamus — E. Helps Regulate Homeostasis And Functions Such As
Temperature, Hunger, Thirst, And Endocrine Activity

, G- Entorhinal Cortex — B. Receives Input From Cerebral Cortex And Projects To The
Hippocampus
H- Interthalamic Adhesion — C. Connects The Two Thalami Across The Third
Ventricle
I- Corpus Callosum — A. Connects The Two Cerebral Hemispheres And Allows
Communication Between Them
Explanation:
These Structures Are Associated With Sensory Processing And The Neural Systems
Involved In Integrating, Regulating, And Transmitting Information Within The Brain.


Question 4.
Using Below Image Of General Senses, Name Parts Labeled: 1,2,3,4,5,6,7 And Match
With Their Roles.




Choices
-Pacinian Corpuscles
-Muscle Spindles
-Tendon Organs
-Merkel Discs
-Meissner's Corpuscles/Corpuscles Of Touch
-Ruffini's Corpuscles
