Title: Sensory and Motor Mechanics


1
  • Chapter 50
  • Sensory and Motor Mechanics
  • By Angela Maggio and Hasina Noory

2
Sensory Pathways
  • Sensory receptors
  • Sensory reception vs. transduction
  • The receptor potential controls action potential
    in central nervous system
  • Signal tranduction pathways

3
Sensory Receptors
  • Mechanoreceptors
  • Stimulated by physical stimuli
  • Thermoreceptors
  • Respond to heat or cold
  • Chemoreceptors
  • Transmit info about solute concentration in a
    solution
  • Electromagnetic receptors
  • Detect various forms of electromagnetic energy
  • Pain receptors
  • Respond to excess heat or pressure from damaged
    tissue

4
The ear )
  • Three regions in mammalian ear
  • Outer, middle, and inner ear

5
Taste Buds
  • Taste buds are modified epithelial cells situated
    on different parts of the tongue and mouth
