Summary Introduction
Introduction:
Neurons are the fundamental units of both the brain and the nervous system. They play an important role in the peripheral nervous system and the central nervous system for cellular communication. Neurons or nerve cells communicate with other body cells through synapses. These neurons’ work is unidirectional because they receive and transfer information in one direction only.

- Describe how the brain receives information about the light entering the eye. You should include the names of structures in your answer.arrow_forwardGiven that frogs are nearsighted in air, which statement is most likely to be true about their vision in water? (a) They are even more nearsighted; because water has a higher index of refraction than air, a frog’s ability to focus light increases in water. (b) They are less nearsighted, because the cornea is less effective at refracting light in water than in air. (c) Their vision is no different, because only structures that are internal to the eye can affect the eye’s ability to focus. (d) The images projected on the retina are no longer inverted, because the eye in water functions as a diverging lens rather than a converging lens.arrow_forwardWhich statement is accurate about the cochlear duct? a. It detects linear acceleration of the head when the otolithic membrane bends the hair cells. b. It is filled with perilymph. c. It contains hair cells that convert sound waves into nerve signals. d.
