MT CH7 Symptoms And Treatment

Question 1

What is the Babinski reflex?

Answer 1

A spreading of the outer toes and extension of the big toe over the others when the sole of the foot is stroked; normal in infants but indicates a lesion of specific motor tracts in adults.

This reflex is named after Joseph Babinski, a French neurologist, and is used in neurological examinations.

Question 2

Define evoked potentials.

Answer 2

Record of the brain’s electric activity after sensory stimulation, including visual evoked potentials (VEPs), brainstem auditory evoked potentials (BAEPs), and somatosensory evoked potentials (SEPs).

These tests evaluate CNS function by measuring the brain’s response to stimuli.

Question 3

What is the Glasgow Coma Scale?

Answer 3

A system for assessing level of consciousness (LOC) by assigning a score to each of three responses: eye opening, motor responses, and verbal responses.

It is commonly used in clinical settings to assess patients with neurological impairments.

Question 4

What does positron emission tomography (PET) utilize?

Answer 4

Radioactive glucose or other metabolically active substances to produce images of biochemical activity in tissues.

PET scans are used for studying the living brain, both healthy and diseased, and are also applied in cardiology.

Question 5

What does the Romberg sign indicate?

Answer 5

Inability to maintain balance when the eyes are shut and the feet are close together.

This sign is often used in neurological examinations to assess proprioceptive function.

Question 6

Define sympathectomy.

Answer 6

Interruption of sympathetic nerve transmission either surgically or chemically.

This procedure can be used to treat various conditions, including excessive sweating and certain pain syndromes.

Question 7

What is trephination?

Answer 7

Cutting a piece of bone out of the skull using a trepan or trephine.

This ancient surgical procedure is sometimes performed to relieve pressure on the brain.
