SENSORY SYSTEMS
&
THE HUMAN EYE
Rods and Cones in the retina of the eye. Rods are receptors
sensitive to dim light but not color. Cones need a lot of light
but are sensitivee to color.

SENSORY SYSTEMS
READING:
Chapter 12 “Introduction To The Human Body”
OUTCOMES:
A) Define “sensation”, “generator potential”, and “sensory pathway” and explain how they
are related in structure and function. (page 315)
B) Describe the 2 characteristics of sensation. (315)
C) Describe the different types of receptors based on location, type of stimulus detected, and
whether they are simple or complex. (pages 315-316)
D) Be able to describe the structure of the eye, how light is refracted, and how the image is
focused on the retina. (pages 323-331 and lab)
E) Explain how the rods and cones form generator potentials that result in images. (326-327)
F) Be able to explain the pathway an impulse takes from the rods and cones in the eye to the
occipital lobe of the cerebrum. (pages 331)
E) Be able to describe the main structures of the ear, and the functions of the cochlea and the
semi-circular canals (331-338)

SENSORY SYSTEM LAB
PART A:
Using the sheep eye and the lab direction sheet provided identify the following structures as to
location and function. Be able to describe all structures that light passes through in order to reach
the receptors in the retina.

Label the structures of the retina shown below. Include all structures observed in Fig. 12.8 of your textbook.
The retina is said to be an inverted
retina. In the space to the right
explain what the term refers to and
why the retina might be structured
as such.
Label the following structures of the
retina.
Rods
Cones
Bipolar neurons
Ganglion neurons
