Study Notes
Autonomic Nervous System
- Coordinates internal organs through sympathetic and parasympathetic systems.
- Not responsible for high-level cognitive functions, emotions, or balance.
Sympathetic Nervous System
- Major function is orchestrating the stress response (fight or flight).
- Key role in emergency preparation; does not coordinate fine motor movement.
Parasympathetic Nervous System
- Maintains day-to-day body functions, particularly digestion.
- Functions to conserve energy and manage routine physiological activities.
Motor Cortex
- Located in the frontal lobe, responsible for voluntary skeletal movements.
- Coordinates fine motor actions and eye movement control.
Thalamus
- Major integration center for pain perception and other sensations.
- Acts as a relay between the basal ganglia and cerebellum.
Proprioception
- Refers to the awareness of body position, dependent on the parietal lobe.
- Essential for the body’s recognition of spatial positioning.
Cranial Nerve XI
- Responsible for shoulder shrugging; evaluation required when this function is impaired.
- Other cranial nerves are associated with different sensory and motor functions.
Brain Growth
- Major brain growth and myelination occurs in the first year of life.
- Critical developmental period for neurological systems.
Motor Maturation
- Follows a cephalocaudal progression, starting from the head and moving downward.
- Essential for understanding developmental milestones in infants.
Neurologic History
- Should include data pertaining to neurovascular problems such as strokes or aneurysms.
- Other elements like educational level and immunizations are less relevant.
Romberg Sign
- Indicates balance; a positive result is observed when a person loses balance with feet together and eyes closed.
Finger-to-Nose Test
- Assesses coordination and fine motor function through a simple movement task.
Two-Point Discrimination
- Most acute on fingertips where two points can be discerned 2-8 mm apart.
- Less sensitive in areas like the back and chest.
Cerebellar Ataxia
- Characterized by a wide-based gait and staggering movements.
- Indicates potential cerebellar dysfunction.
Deep Pressure Tests
- Used when superficial pain sensation is absent to assess neurologic function.
Stereognosis
- Ability to recognize objects by touch, tested by placing objects in the hand with eyes closed.
Brown-Séquard Syndrome
- Characterized by motor paralysis and proprioceptive loss on the same side of the body as the lesion.
- Pain and temperature sensation loss occurs on the opposite side.
Monofilament Testing
- Assesses sensory function by applying pressure until filament bends, crucial for diabetic neuropathy assessments.
Ankle Clonus
- Tested when deep tendon reflexes are hyperactive; clonus indicates upper motor neuron lesions.
Meningeal Signs
- Brudzinski and Kernig signs are used to assess for meningeal irritation.
Cranial Nerve XII in Infants
- Assessed by observing sucking and swallowing; indicates proper nerve function.
Concerns in Older Adults
- Bilateral pill-rolling hand movements could indicate Parkinson's disease, while other findings may be expected with aging.
Stroke Indicators
- CVA symptoms include personality changes and hemiplegia; anterior cerebral artery involvement is typically associated with leg motor control.
Guillain-Barré Syndrome
- Autoimmune disorder leading to acute neuromuscular paralysis post-infection.
Myasthenia Gravis
- An autoimmune disorder where the immune system attacks acetylcholine receptors, affecting muscle activation.
Pseudotumor Cerebri
- Condition mimicking brain tumors due to increased intracranial pressure, associated with conditions like obesity.
