From the list below, what are two examples of structures or organs which are innervated only by the sympathetic division of the autonomic nervous system? (choose all that apply)

Hair cells of the macula have a special “true stereocilium” known as the  _______ which are located next to the tallest stereocilia. 

Almost all the smooth muscle within blood vessels is innervated entirely by parasympathetic fibers.

Once the preganglionic axons of the sympathetic division reach a synaptic trunk (chain) ganglion one of three things can happen, they can synapse at the same level, they can synapse at a higher or lower level along the synaptic trunk, or they can pass through the synaptic trunk without synapsing. 

_____________ is the strange eye movement during and immediately after rotation and is often accompanied with vertigo. 

During  _______ both rods and cones are simultaneously stimulated causing large amounts of visual pigment to be instantaneously broken down. Visual acuity does improve quickly, in about 5-10 minutes, once retinal sensitivity decreases as the rod system is shut down. 

Compare and contrast lipid-soluble hormones and water-soluble hormones. To receive full credit the discussion needs to include three of the following aspects: source, how the hormone is transported in the blood, the half-life in the blood, location of hormone receptors on the target cell, or mechanism of action at the target cell.            

 What hormone is a strong stimulant for uterine contraction during childbirth and acts to trigger milk ejection? 

Vision is maintained because the outer segment of photoreceptors is renewed every 24 hours. 

_______ are the long-distance chemical signals used by the endocrine system which can travel through either the blood or the  _______ to target cells.
