Would TSH levels be low or high in the case of a primary hypothyroidism? Would TSH
levels be low or high in the case of a secondary hypothyroidism? Justify your answers
by
referring to Figure 9 in the Pictorial Study Guide.

In a primary hypothyroidism, the thyroid gland is not functioning to
produce thyroid hormone. As a result, there is no negative feedback on
TSH and so TSH levels are high.
In a secondary hypothyroidism, the problem is with the anterior pituitary
gland - it is not producing TSH and so TSH levels are low.
What form of neuromuscular pathology is associated with a high amplitude, low
frequency EMG tracing?

, This pattern is associated with neuropathy
What is the difference between assessing blood pressure by auscultation and
assessing blood pressure by palpation?
Give this one a try later!
Both use a sphygmomanometer but auscultation uses a stethoscope over
the brachial artery, whereby palpation involves no stethoscope and
palpation of the brachial or radial artery.
What do you expect to happen to the amplitude of the EMG spikes as a muscle
contracts with more force?

It is expected that they will increase.

What is the anatomical explanation for why humans have sharper vision in the
central aspects of their visual fields than in the peripheral visual fields?
Give this one a try later!
Neural pathways extend from each photoreceptor in the central
retina into visual cortex. This allows the brain to precisely determine
where light has struck the central retina and produces sharp vision.
In contrast, in the peripheral retina each neural pathway carries
signals collected from several photoreceptors. While this improves
light sensitivity, it produces a fuzzier image of the world.
