24
Q

Where is the grey mater and white matter of the spinal cord

A

Inner is gray matter

outer is white matter

25
What is the gray matter of the spinal cord composed of
Nerve cells body processes neuroglia blood vessels
26
Where is the autonomic nervous system located in gray matter of spinal cord
Lateral horn in the thoracic and and upper lumbar region
27
What link do white and left side of the gray matter
The gray commissure
28
What determines the amount of gray matter in spinal cord
The amount of neurons presents at that level
29
What is the hole in the middle of the grey mater
The central canal
30
what are the nerve cell groups in the posterior column of the grey mater
Substantia gelatinosa nucleus propius nucleu’s dorsalis visceral afferent nucleus
31
What is Substantia gelatinosa
Fibers Carrying pain , touch, and temperature information synapse with small neuron fibers of Substantia gelatinosa to carry them to the brain Also contain descending fibers from Supraspinal levels Axons gives rise to contralateral spinothalamic tract
32
What is the nucleus proprius
Receives proprioceptive fibers like position and movement and two points discrimination and vibration from posterior white column through the spinocerebellar tract
33
What is nucleus dorsalis
Column from C8 to L3 which is associated with proprioceptive endings like neuromuscular and tendon spindle
34
What is the visceral afferent nucleus
Medium sized cells which form columns from T1 to L3 located lateral to nucleus dorsalis and receives visceral afferent information
35
Where does the Lateral gray column extends from
From T1 to L3
36
What is the function of the lateral gray column
Give rise to preganglionic sympathetic fibers
37
What do you find in the anterior Grey column
Lower motor neurons | of type alpha and gamma efferent neurons
38
What do the alpha efferent nerves of the interior Grey column innervates
Skeleton muscles
39
What do the gamma efferent nerves of the interior Grey column innervates
Ultrafusal muscle spindle
40
What are the divisions of the Anterior Grey column
Medial central group lateral
41
What does the medial division of the anterior grey column innervates
The axial musculature
42
where is the central group Of the anterior curriculumlocated and what does it innervate
She 34 and five innervates phrenic nucleus C1-c5 or c6 Innervates accessory nucleus of sternocleidomastoid and trapezius Lumbo sacral nucleus L2 to S1
43
Where is the Lateral division of the enter your great column located and what does innervate
Located in the cervical and lumbar sacral segments | innervates appendicular muscles dorsal flexors and ventral extensors
44
Where do you find ascending tracts in the white matter
All funiculi
45
Where do you find descending tracts in the white matter
In the Lateral and Anterior funiculi
46
Where do you find fasciculus gracilis
In all segments of the cord
47
Where do you find fasciculus cuneatus
In the upper thoracic and cervical
48
Where does information of fasciculus Gracilis and cuneatu
In the Gracilis nucleus And cuneatus nucleus In the medulla oblongata
49
What are the ascending tracts of the Lateral white matter
The Lateral spinothalamic tract The dorsal spinocerebellar tract The ventral spinocerebellar tract The Spino olivary tract
50
What are the ascending tracts of the anterior white matter
The ventral spinothalamic tract
51
Where do the descending pathway of the spinal cord to the white matter arise from
From the cerebral cortex the corticospinal tract and the brain stem
52
What are the function of the descending tracts going to the white matter of the spinal cord
Movements muscle tone posture modulation the spinal reflexes activities
53
What are the descending tracts of the white matter of the spinal
``` Lateral corticospinal tract ventral corticospinal tract rubrospinal track Tectospinal tract vestibulospinal tract reticulo spinal tract ```
54
What blood vessel supply the spinal cord
The anterior and posterior spinal arteries which branch of vertebral artery The radicular or segmental medullary arteries which are branches of the intercoastal lumbar and lateral sacral arteries
55
Dural sac Which is enlargement of subarachnoid space and id present at the l1-l2 level
Lumbar cistern
56
Sites of lumbar puncture
Lumbar cistern
