Neuro patho (SCL) Flashcards
What does the spinothalamic tract do
Pain and temp
What does the dorsal column do
Touch, position, sense, vibration
What does the spinocerebellar tract do
Proprioceptive information
What’s a spinal cord lesion
Spinal cord is vital for conveying and integrating sensory and motor information to and from the periphery, a SCI may impair motor, sensory and autonomic functions depending on extent and level of lesion
Examples of non traumatic lesions
Degenerative disc disease, spinal cord stenosis, spinal infarction, inflammation of spinal cord, viral infection, developmental and congenital abnormalities
Vulnerable areas of the vertebral column
C spine c5-7
T12
T4-7
Patho of spinal cord injuries
Oxygenation, perfusion and acid/base balance to aid management if the injury, oedema amend altered blood flow account for clinical deterioration,
3 different mechanisms: destruction from direct trauma, compression by bone fragment, hématome or disc material, ischaemia from damage or impingement it spinal arteries
Difference between tetraplegia and quadraplegia
Impairment or loss of motor control and sensory function in cervical segments of the cord, tetraplegia affects all 4 limbs
Impairment or loss of motor control and sensory function in the thoracic, lumbar of sacral segments of the cord, depending on level of injury, trunk, legs and pelvis may be involved
What’s a complete spinal cord lesion
Complete loss of function below point of injury, damage to descending pathways, damage to anterior motor neurone , spinal shock at level of lesion, complete destruction of nerve cells, flaccidity, gradually anterior horn cells below level of lesion recover but have no control from higher centres
What’s an incomplete spinal cord lesion
Some sparing of neural activity below level of lesion
Central cord syndrome, anterior cord syndrome, brown sequard syndrome, cauda equina syndrome
What’s total transaction of the cord
Results in impairment of deep and superficial sensation, autonomic dysfunction, impairment of vaso motor control, postural hypertension, autonomic dysteflexia, problems with bladder and bowel function, problems with sexual function
What’s the ASIA scale and how does it classify a stroke
Determine sensory level on both sides, determine motor level on both sides, determine single neurological level, determine whether the injury is complete or incomplete, determine ASIA impaire,not scale grade
Myotomes the group of muscles a single spinal nerve innervates and dermatomes are an area of skin a single nerve innervates
C5- elbow flexors L2-hip flexors
C6- wrist extensors/flexors. L3- knee extensors
C7-elbow extensors L4 - ankle dorisflexion
C8-finger flexors L5- long toe extensors
T1- finger abduction S1- ankle plantar flexors
