exam 1

• The olfactory system is the sensory pathway that does not pass through the thalamus before terminating in the cerebral cortex
• The eustachian tube regulates air pressure in the middle ear, while the spiral organ is the receptor for hearing
• Taste buds are located on elevations on the tongue called papillae
• The retina is the part of the eye that converts light energy into neural impulses
• The iris controls the size of the pupil
• Basal stem cells produce new olfactory receptor cells
• The blind spot in the eye is the point at which the optic nerve exits the eye, known as the optic disc
• Three semicircular canals help maintain dynamic equilibrium, which is the maintenance of the body’s position in response to sudden movements. Static equilibrium, the maintenance of the body’s position relative to the force of gravity, is also important
