What is a general/somatic sense with regards to location and complexity of the
receptor structure?
Includes temperature, pain, touch, pressure, vibration, proprioception.
Receptors are scattered all over body, and they are simple in structure
What is a special sense with regards to location and complexity of the receptor
structure?
Includes olfaction (smell), vision (sight), gustation (taste), equilibrium (balance) and
hearing.
Receptors are located in specific sense organs and are structurally complex
What is a Nociceptors?
pain receptors
Located: Superficial Skin, Joints, bones, blood vessels
Sensitive to :temp. Mechanical damage, dissolved chemicals
What is a Thermorereceptor?
Temperature receptors
- located: deep skin, skeletal muscle, liver, hypothalamus we both have cold & warm
thermoreceptors
What is a mechanoreceptor?
- sensitive to stimuli that distort their Plasma membrane
EX. Heavy Pressure, vibration, light touch, skin stretch
What are the three types of mechanoreceptors?
proprioceptors, baroreceptors, tactile receptors
What is propericeptor?
Monitor the position of the joints & muscles
what is baroreceptors?
- Pressure receptor inside blood vessels
monitors blood pressure
what is tactile receptors?
Receptors for touch, pressure, vibrations
•many located in the skin
what is a chemoreceptor?
- Detects changes in the concentration
Of substances dissolve in body fluid
Ex. PH, CO levels, nutrient levels etc.
