Flashcards in Neuro Vocab and stuff Deck (33):
The sensation of pain in response to a stimulus that would not typically produce pain
The absence of pain while remaining conscious?
Constant, relentless, burning hyperesthesia and hyperalgesia that develops after a peripheral nerve injury
The absence of touch sensation
Distortion of any of the senses, especially the sense of touch
extreme sensitivity to pain.
Hyperalgia. Also called hyperalgesia.
Extreme exaggerated response to pain
A diminished sensation of touch
Severe and multiple shock-like pains that radiate from a specific nerve distribution
Loss of vibration sensation
Abnormal sensation such as tingling, pins-and-needles, or burning sensations
Damage to this nerve can occur with fracture of the calcaneus or lateral malleolus
Damage to this nerve can occur with tarsal tunnel entrapment or popliteal fossa compression
Damage to this nerve can occur with Femur, tibia, or fibula fracture, positioning during surgical procedures
Damage to this nerve can occur with fixation of a femur fracture, total hip arthroplasty
Damage to this nerve can occur with blunt force trauma to the buttocks, total hip arthroplasty, accidental injection to the nerve
Damage to this nerve can occur with total hip arthoplasty, displaced acetabular fracture, anterior dislocation of the femur, hysterectomy, appendectomy
Degeneration that occurs distally, specfically to the myelin sheath and axon
Abnormal growth of nerve cells (neuroma) can occur with which patholgoies
Including, but not limited to: vascularitis, AIDS, and amyloidosis
Polyneuroathy - diffuse nerve dysfunction that is symmetrical and typically secondary to pathology and not trauma - is associated with what conditions?
GBS, peripheral neuropathy, HIV, and use of neurotoxic drugs
What is Barognosis?
perceive the weight of different objects in the hand.
How can you test deep pain?
Squeeze the calf or forearm muscle.
The tectum is in which part of the brain, and what makes up the tectum?
Midbrain; superior and inferior colliculi
What makes up the telencephalon in the forebrain?
Cerebrum (cerebral cortex), hippocampus, basla ganglia, and amygdala
Where is grey matter in relation to white matter?
Over the white matter in the brain, but under the white matter in the spinal cord.`
What is Alexia? Damage to what part of the brain causes this?
Also known as dyslexia- impairment of reading ability. Caused by damaged to parietal lobe's dominant (usually left) hemisphere.
What is?inability to interpret sensations and hence to recognize things, typically as a result of brain damage.?
Agnosia - usually caused by damage to parietal lobe's dominant (left) hemisphere
What is dressing apraxia?
A dressing dyspraxia is an inability to perform the relatively complex task of dressing and is commonly associated with lesions of the non-dominant parietal hemisphere. It can be tested by taking the patient's pyjama top, turning it inside out and asking for it to be put back on.
What makes up the diencephalon?
Thalamus, hypothalamus, subthalamus, and epithalamus.
What characterizes an upper motor neuron disease?
A lesion found in desecending motor tracts within the cerebral motor cortex, internal capsule, brainstem, or spinal cord. Symptoms include weakenss of involved msucles, hypertonicity, hyperreflexia, mild disue atrophy, and abnormal reflexes. Damaged tracts are in the lateral white column of the spinal cord. Some examples are CP, MS, and TBI.
What characterizes a lower motor neuron disease?
A lesion that affects nerve or their axons at or below the level of the brainstem, usually within the "final common pathway." The ventral gray column of the spinal cord may also be affected. Symptoms include flaccicity or weakness of the involved muscles, decreased tone, fascicilations (brief spontaneous contraction, flicker of muscle under the skin), muscle atrophy, and decreased/absent reflexes.`
