L1 - Diseases of the Neuosensory system: Intro Flashcards
1. Revise neurosensory anatomy and physiology 2. Lesion and location 3. Clinico-anatomical method in neuroscience 4. General review of disease types 5. General principles of disease course
What part of the brain is a common area for focal epilepsy?
Hippocampus
Where is Broca’s area found?
Frontal lobe.
Controls motor functions involved with speech production and language comprehension.
What is Brown-Sequard syndrome?
- Lesion in spinal cord.
- Results in weakness or paralysis (hemiparaplegia) on one side of the body and loss of sensation (hemianesthesia) on opposite side.
Where do axons in spinothalamic tract decussate?
Ventral white commissure.
Damage to what tract causes Brown-Sequard syndrome?
Corticospinal
What is Ptosis?
muscle involved?
Eyelid droop with inability to close eyes.
Ptosis: weakness of levator palpebrae superiorsis.
Weakness in what muscle may cause inability to close eyes?
Obicularis Oculi
What nerve innervates levator palpebrae superioris?
CN III - Oculomotor
What innervates obicularis oculi?
CN VII - Facial
What is myasthenia gravis?
- Due to autoimmunity against ACh receptors in muscle end plate.
- Causes weakness in skeletal muscles, responsible for breathing and moving parts of body
What medical term is given to slowness of movement in body hands?
Bradykinesia
What may slowness of movement in both hands indicate?
- Lesion in basal ganglia bilaterally.
- Indicative of Parkinson’s disease
