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.
