Introduction

Biological communication occurs at many levels, from one cell communication with its neighbour in a tissue (paracrine, to signals released into the blood from one cell to signal to another cell or tissue (endocrine or hormone signaling). The signalling that occurs in the brain, spinal cord and other nervous tissues involves electrical (action potentials) signaling.

This page will introduce development of signaling in our special sensory nervous systems: the eyes for vision and the ears for hearing. Both systems convert signals in one medium (light or sound) into an electrical signal that our brain can understand.

This content is only as a brief introduction, designed for K12 students. More detailed information can be found on the listed linked pages.

Hearing - Sound

Hearing cartoon.jpg

This cartoon shows the adult "ear" with the 3 main divisions (outer, middle, inner).

Vision - Light

Eye and retina cartoon.jpg

This cartoon[1] shows the eyeball (left), a cartoon of the retina cells (middle) and an actual slice of the human retina.


The Eye
  • This is a cut through the eyeball showing the eye anatomy.
  • The retina forms the inner lining of the most of the back part of the eye.
Retinal Cell Organization

These are the names of the cells and neurones required to convert light into electrical signals.

  • G - retinal ganglion cells (form the ganglion cell layer)
  • M - Müller cell
  • A - amacrine cell
  • B - bipolar cell
  • H - horizontal cell
  • R - rod (detect light)
  • C - cone (detect light)
Human Retina Histology

This is a thin section of the retina that has been stained with dyes so that you can see the structure shown in the cartoon.
