Lesson 27: Sense organs

Hi,

More on the nervous system and the eye. Please remember that only the eye and skin are in the syllabus now. The other sense organs are still very interesting, but they will not be tested in the exams.

This set of slides contain the following:
  • sense organs eye and skin, and nervous system and reflex actions
  • stimulus, receptor, coordination, effector, response sequences
  • nerve cell, labels, annotation
  • how synapse works
  • pupil reflex, blink reflex, cough reflex
  • labels in reflex actions, annotated diagram
  • eye, labels, annotations
  • compare eye with camera in its functions
  • short and long-sightedness
  • short questions
Remember not to dwell too much on the ear, tongue, nose, other parts which will not be tested in your examinations.



Cheers
