CONCEPT Somatic Sense 4 Dan is dehydrated. Which type of receptor alerts his brain of this?  Osmoreceptor  Thermoreceptor  Chemoreceptor  Mechanoreceptor CONCEPT Sensory Receptors 5 What parts of the mouth contain taste receptors?  Tongue and roof of the mouth  Tongue and throat  Throat and roof of the mouth  Tongue, throat and roof of the mouth CONCEPT Smell & Taste 6 Select the FALSE statement about stem cells.  They are unspecialized cells found in undeveloped embryos and adult bodies.  They are specialized cells found in the central and peripheral nervous systems.  Scientists manipulate these cells to produce new types of cells.  Scientists are researching ways that these cells can repair damaged parts of the nervous system. CONCEPT Stem Cells 7 How are signals transmitted using neurotransmitters?  From the synapse to the presynaptic cell, and then to the postsynaptic cell  From the postsynaptic cell to the presynaptic cell across a synapse  From the presynaptic cell to the postsynaptic cell across a synapse  From the presynaptic cell to the postsynaptic cell, and then to a synapse CONCEPT Neurotransmitters 8 Which of the following statements is true?  The tectorial membrane is a structure in the cochlea that hair cells interact with to produce action potentials.  Sound is mechanical energy that travels in the form of subatomic particles.  The otolith organ carries signals from the inner ear to the brain.  Sound coming into the ear first encounters the cochlea.
