Without the presence of _______, sensations of pain in a somatic location that are not due to nociceptor stimulation in that region may not be experienced. A.) third order neurons B.) mechanoreceptors C.) interneurons D.) receptive fields E.) autonomic neurons

Using the terms for a homeostatic negative feedback loop or a reflex, describe both the function AND anatomical elements serving that function for each of the following as it applies to the baroreceptor reflex known as: a.) motor pathway b.) receptors c.) sensory pathways

The optic nerves form synapses in the ____ nucleus of the thalamus, which relays the information to the primary visual cortex in the ___ lobes. A) medial geniculate; parietal B) medial geniculate; occipital C) lateral geniculate; occipital D) lateral geniculate; parietal

Dr. Kirk tells her assistant to look for activity in areas ipsilateral to the amygdala in the right hemisphere. Where should her assistant look? A) In the right hemisphere B) In both occipital lobes C) In the left hemisphere D) In both frontal lobes

An example of a sensory neuron is one that leads from a pain receptor in the finger to the spinal cord. A pin can be pressed against the skin without eliciting a response from the pain receptor. However, if the pin is jabbed into the finger, the pain receptor may be stimulated and the finger would quickly withdrawn through a reflex arc.  How do we sense different types of pain (very painful vs. not painful at all)? Using what you understand about threshold potentials and the all-or-none principle, explain how it is possible to sense different levels of pain.    question is in bold

Which options are true regarding the gate control theory of pain? Select all that apply: a. Mechanoreceptor fibres synapse directly onto nociceptor fibres and potentiate incoming pain signals b. Mechanoreceptor fibres synapse onto interneurons, which synapse onto nociceptor fibres and potentiate incoming pain signals c. Applying a mechanical stimulus, such as grabbing the injured area, will soothe the injury d. Mechanoreceptor fibres synapse directly onto nociceptor fibres and inhibit incoming pain signals e. Mechanoreceptor fibres synapse onto interneurons, which synapse onto nociceptor fibres and inhibit incoming pain signals f. Applying a mechanical stimulus, such as grabbing the injured area, is a natural defensive reaction, but does little to actually affect incoming pain signals.
