Q

Meaning of Soma topically:

A

neurons enter the spinal cord at a lower level are positioned more medially within the spinal cord.
Neurons that are higher level of the spinal cord are positioned more laterally within the spinal cord.
Flexors=dorsal
Extensors=ventral

Q

Difference b/w Nucleus/Ganglion

A

Nucleus CNS, ganglion in the PNS

17
Q

Spinothalamic Tract what kind of pathway?

A

Sensory, Ascending

18
Q

Type of Information is carried Spinothalamic tract?

A

pain, temperature and crude touch sustained pressure

19
Q

Define Anterolateral and Ventrolateral System

A

Spinothalamic tract-anterolateral-ventrolateral system. Anterolateral system is the pathway via which pain signals are carried to the sensory cortex

20
Q

Type of info Lateral Spinothalamic

A

pain/temp

21
Q

Type of info Anterior Spinothalamic

A

Crude touch pressure

22
Q

Lissauer’s tract

A

Crude touch and pressure-related axons ascend or descend 1-2 spinal levels
Spinothalamic tract neurons enter the spinal cords via Lissaeur’s fasciculus and ascending descending 1-2 spinal levels before synapsing with a neuro in the dorsal horn of the grey matter.

2nd Neuron the decussates and ascends via the spinothalamic fasciculus.

23
Q

What is the Substania Gelatinosa and Nucleus proprius?

A

1st Synapse in the spinothalamic tract

24
Q

Anterior White Commisure?

A

Site of decussation of the 2nd order neurons in the spinothalamic tract

25
Q

SpinoCerebellar Pathway what type?

A

Sensory, Ipsilateral ascending

26
Q

Role of the Spinocerebellar?

A

carries unconscious propioceptive sensations from the body, through the spinal card to the cerebellum

27
Q

Clarke’s nucleus and what levels does it only exist in and number Laminae?

A

beginning of the spinocerebellar pathway
C8-L2
Laminae 7

28
Q

Ventral SpinoCerebellar

A

relays proprioceptive and ex

29
Q

Ventral SpinoCerebellar

A

Relays Proprioceptive and Exteroceptive from the ipsilateral limb and lower limb assistnace in coordination of movements of lower limb and mm

30
Q

Anterior Spinocerebellar

A

Proprioception from the ipsilateral skeletal mm, joints tendons in ipsilateral torso and lower limb

31
Q

Rostral SpinoCerebellar

A

Propioceptive input from ipsilateral head and upper limb. assists in movement of head and upper limb

32
Q

Cuneocerebellar

A

propioceptive information from ipsilaterla neck and upper limb.

33
Q

Lateral Corticospinal tract

A

conveys commands for fine movement of ipsilateral limbs

34
Q

Anterior Corticospinal Tract

A

Conveys commands for movements of the contra-lateral axial mm

35
Q

Anterior White Commissure

A

bundle of nerve fibres which cross the midline of the spinal cord. Deccuastion
