How is TIA managed In primary care?
Assess risk of stroke or TIA in next 7 days in guidance and refere to specialist if needed
What contributes to high risk of recurrent stroke or TIA?
ABCDsquared above 60 High BP clincial features duration diabetes AF more than one week or on anticoagulant
What to do in low risk TIA patient?
Refer from assessment, statin antiplatelet, treat BP no driving till seen specialist
What layer are the somites made of?
Mesoderm
What are derived from somites?
dermatomes and myotomes (skeletal only)
What are branchial arches?
Bumps belwo the head around the neck they are a feature of vertibrates
Which area are sympathetic nerves derived from?
T1-L2
Which cranial nerves are carying autonomic nerves/
3,7,9,10 1973
What makes up peripheral nervous system?
spinal cord C8 T12 L5 S5 some (1)coygeal ones, then the ones from the brain cranial nerves somatic branchial autonomic and special
Where are the Thoracic dermotomes?
They are from the sinal level at the back to slightly lower at the front they run from above the ribs down to the suprapubic area T1 gos down the inside of the outer arm
Where is the foregut pain felt/
In T5 to T9 dermatomes in epigastrium
Where does hindgut pain feld?
In T12 region suprapubically
Where does the spinal cord end?
At around L1
What is important about spinal cord deficites level?
Spinal cord level is where the bodies of the cells are in the cord where as the vertebral level is where they ender the spinal column
Where does the splanchnic nerves come from?
They come from the sympathetic chain
What is the corticospinal tract?
Motor tract from the cortex through internal capsule in thalamus, to thepons and medulla where 85% cross to the contralateral side to the lateral corticospinal tract 5% are on ipsilateral spinal tract the other 1-0 are in the ipsilateral anteria corticospinal tract
What is significance of decusation of the corticospinal tract?
if you hafe brain or stem injury it will affect contralateral side otherwise it affectsthe same side if below the medulla
What does anterior corticospinal tract do?
Muscles of the trunk
What happens with anterior decussation?
Happens in the thoracic cord not the pyramids
What is in the ventral horn of the spinal cord?
the motor nerves
What are in the dorsal horm of spinal cord?
The sensory nerves
What happens with thoracic spinal hemisection in corticospinal?
Loss of motor to the same side for the limb but opposite for the trunk
What doe the dorsal columns carry?
They carry touch vibration concious muscle/joint sense
