Thrombocytopenia
decreased platelets numbers
Hypercoagulability
increased tendency to clot

genetic bleeding disorder associated with deficiency of clotting factor VIII
Haemophilia B
genetic bleeding disorder associated with deficiency of clotting factor IX
Polycythaemia
high number of red blood cells
Hypoxia
low level of oxygen in body tissue
Haemochromatosis
when body absorbs and stores too much iron from diet – results in oxidative stress

- Cranial Park: brainstem (CN 3,7,9,10)
- Caudal part: Spinal cord segments S2-S4
What does the ACA supply
- Medial surface of the frontal and parietal lobes
- Superior part of motor and sensory cortex (especially lower limb area)
- Corpus callosum (anterior 4/5)
- Parts of the cingulate gyrus
Stroke – Leg weakness/sensory loss, personality change
What does the MCA supply
- Lateral surface of frontal, parietal, and temporal lobes
- Primary motor and sensory cortex (especially face and upper limb areas)
- Broca’s and Wernicke’s areas (dominant hemisphere)
- Internal capsule, basal ganglia (via deep branches)
Stroke – Face/arm weakness, aphasia or neglect
What does the PCA supply
- Occipital lobe (primary visual cortex)
- Inferior temporal lobe
- Thalamus, midbrain, posterior corpus callosum
Stroke – Visual field defects, sensory loss
what is purulent exudate
a thick yellow fluid which contains dead neutrophils, bacteria, cell debris and protein rich fluid
What is serious educate
a clear watery fluid which is low in cells and protein, is typically seen in early inflammation, blisters or mild injuries
