1. Assume you could âlookâ into the musculature of an animal andwatch neurosecetion as an animal moved. What would you see?
a. dynamic neurosecretionb. dynamic patterns ofneurosecretion
2. The word organ denotes adistinct set of tissues performing one or more specificfunctions. Therefore, this termcan be used to refer to large visceral organs, e.g. the liver, or much smaller structuressuch as otolith organs. In regard to the otolith organs, whatcauses the cilia of their vestibular cells to bend?
a, shear force b.inertia of endolymph
3. Recall that thevestibulo-ocular reflex enables the eyes to remain fixed on targetand that extrinsic eye muscles are innervated by brainstem α-motorneurons. What role does the medial longitudinal fasciculus play inthe vestibulo-ocular reflex?
a. central integration b. links the vestibular nuclei with brainstem motornuclei
4. Descending projections fromthe vestibular nuclei enable postural adjustments of the head andbody. Any stereotypical change in head position that promotes balance is mediated by thevestibulo-cervical reflex. This name stems from the fact that mostof the α-motor neurons that control the position of the head arelocated in the motor nuclei of the
a. brainstem b.cervical cord
5. Any stereotypical changein bodyposition that promotesbalance is mediated by the vestibulo-spinal reflex. Does thisreflex implement the γ-loop?
a. yes b. no
