Neuro Exam Flashcards
What is the primary function of the Corpus Callosum?
Connects the left and right hemispheres of the brain, facilitating interhemispheric communication.
What is the primary function of the Thalamus?
Relays sensory and motor signals to the cerebral cortex; regulates consciousness and sleep.
What is the primary function of the Hypothalamus?
Regulates homeostasis, including hunger, thirst, body temperature, and hormonal control.
What is the primary function of the Pineal Gland?
Produces melatonin and regulates circadian rhythms.
What is the primary function of the Midbrain?
Controls auditory and visual processing and motor movements.
What is the primary function of the Pons?
Relays signals between the cerebrum and cerebellum; regulates sleep and respiratory function.
What is the primary function of the Medulla?
Controls autonomic functions such as heart rate, blood pressure, and breathing.
What is the primary function of the Motor Cortex?
Controls voluntary motor movements.
What is the primary function of the Sensory Cortex?
Processes sensory input such as touch, pressure, and temperature.
What is the primary function of the Cerebellum?
Coordinates voluntary movements, balance, and posture.
What is the primary function of the Temporal Lobe?
Processes auditory information; involved in memory and language comprehension.
What is the primary function of the Frontal Lobe?
Involved in decision-making, planning, problem-solving, and motor control.
What is the primary function of the Occipital Lobe?
Processes visual information.
What are diseases in the thalamus?
Thalamic pain syndrome, sensory processing disorders.
What are diseases in the corpus callosum?
Agenesis of corpus callosum, split-brain syndrome.
What are diseases in the hypothalamus?
Obesity, diabetes insipidus, hypothalamic tumors.
What are diseases in the pineal gland?
Sleep disorders, pineal tumors.
What are diseases in the midbrain?
Parkinson’s disease, midbrain stroke.
What are diseases in the pons?
Locked-in syndrome, pontine stroke.
What are diseases in the medulla?
Respiratory failure, medullary stroke.
What are diseases in the motor cortex?
Paralysis, motor control deficits (e.g., from stroke or traumatic brain injury).
What are diseases in the sensory cortex?
Sensory deficits, numbness, inability to process tactile stimuli.
What are diseases in the cerebellum?
Ataxia, coordination disorders, cerebellar stroke.
What are diseases in the temporal lobe?
Wernicke’s aphasia, memory impairments, temporal lobe epilepsy.
