Short Ascending Tracts

Question 1

بسم الله الرحمن الرحيم وبه نستعين

short ascending tract last station is ?

Answer 1

Cerebellum

Question 2

Short ascending Tract responsible for?

Answer 2

Unconsciuous propriception
to cerbellum to coordinate movment

Question 3

Cerebellar hemispheres are

Answer 3

Ipislateral unlike cerebral hemispheres which are contralateral

Question 4

Mention short ascending tracts

Answer 4

3 spino or 3 cerebellar
Anterior spinocerebellar tract
Posterior spinocerbellar tract
Spino Olivary tract
Cuneo-cerbellar Tract

Question 5

peripheral process of posterior spinocerbellar tract get sensation from ?

Answer 5

Trunk + Lower Limb

Question 6

Where does the 1st neuron of post spinocerbellar tract relay ?

Answer 6

Ipsilatral Clarkes’s Nucleus in dorsal horn

Question 7

Describe posterior spino-cerbellar Tract

Answer 7

Begins from first order nueorn psudounipolar recevieng from reveptors in LL and Trunk by its periphery to the central process entering the spinal cord to
! Ipisilateral Clarke’s Nucleus
givning 2nd order Neuron ascending
Ipsilaterally
In ( Lateral White Column )
post to anterior spinocerebellat tract
reaching midbrain passing throuch inferior Cerbellar Peduncle To Ipisilateral Cerbellum

Question 8

Anteiro spinocerbellar tract take propriception unconsiuocs from ?

Answer 8

Lower limb as posterio ONE

Question 9

A tract in which fibers decussates Twice ?

Answer 9

Antterior Spino Cerbellar Tract
Spino Olivary Tract

Question 10

Describe Anterior Spino Cerbellar Tract ?

Answer 10

First order Neuro Pseudounipolar Neuron take sensation by its peripheral part from the Deep receptors in Lower limb then to central process as dorsal root to
Ipsilateral Clarke’s Nucleus
Most fiber ducssate
some remains ipsilateral
The ducssating fibers ascends till reach the level of midbrain and then decussate another time crossing to the ipsilateral superior cerbellar peduncle with the ipsilateral fibers

Question 11

Peduncles and
ant
post
Spinocerbellar Tracts

Answer 11

Ant at SCP
Post at ICP

Question 12

Spino Olivary Tract describe

Answer 12

First order Neruron Pseudounipolar Nueron take sensation by its periphery from the Receptros in U.L +L.L hten to the dorsal root of spinal cord contiunes as first order neuron without relay in spinal cord decussating then pass to the medulla Contralateral Olivary Nucleus decussating to reach ICP to ipsilateral Cerbellum ?
then de

Question 13

A tract In which First Order Neuron Doesn’t relay on spinal cord ?

Answer 13

Spino olivary tract it contiues till reach the medulla Contra lateral Olivary Nucleus

Question 14

Cuneocerbellar tract

Answer 14

Carries Proprioception from Upper Limb

it is cunate tract bu relay on Acessoy cunate nucleus in medulla then via ICP to ipsilateral cerbellar forming External Arcate Fibers
carries proprception from Upper limbUNCONSCIOUS
