PET scan Case study

Just had a stroke (or brain attack?where portions of the brain die due to a failure in blood flow) and is now extremely aphasic but can still understand and act appropriately on spoken directions. HIS neurologist orders a PET scan. A What do you think the scan will most likely show? B What disability does Sam have, and what Is his most likely prognosis? A. The PET scan will less active areas of the brain In the Wrinkle area of the brain .

The patient’s disability Is probably anomic aphasia. According to our text book, “the person Is able to speak and understand speech but not written words or pictures” Anatomy and Physiology: The unity of Form and Function Salad’s 6th edition 2 Henry was involved in an automobile accident and had a badly traumatized ear. The damage extended into the middle ear (I. E. , the region between the ear drum and the beginning of the inner ear). A Besides the obvious hearing defects resulting, why id Henry notice a significantly reduced salivary flow? Why did he stop making as much saliva as before? Henry has probably some damage to the facial nerve, The facial nerve affects the facial muscles, muscle of middle ear, as well as the salivary glands.

This is possibly why he has noticed the decrease in saliva production Anatomy and Physiology: The Unity of Form and Function Salad’s 6th edition 3 If you placed a tuning fork against your temporal bone, the vibrations would travel Into the Inner ear and you could hear the sound.

When compared to the same sound heard through the ear, which should be louder? B How would Otis media affect your answer? The sound should be louder and longer when held next to your ear as opposed to holding It to your temporal bone (mastoid process). Tootles media can affect this due to Inflammation and possible fluid In the Inner ear. This will affect the vibrations of the tympanis membranes making hearing the sounds through the ear more difficult than through the temporal bone.
