12b sensory receptors (the diff forms of energy converted by …

- - - - mechanical
        
        eg: touch
        pressure
        (baroreceptors)
        vibration
        accceleration
    - - chemical
        ( a change in chem composition
        of the environment in which
        the receptors are located
        
        receptors for
        taste
        smell
        osmoreceptors
        glucoreceptors
    - - thermal
        ( degree of warmth)
    - - noxious
        ( stimuli which are damaging
        or injurious to the body tissues)
        
        eg: pain
    - - electromagnetic
        
        light
        eg rods & cones in retina
  - - - located at on place in the head
        very close to the CNS
        
        are specialized for
        one type of sensory stimulation
        
        information frm them is carried by
        the cranial nerves
        
        eg: vision
        hearing
        smell
        taste
        rotational & linear acceleration
    - - its receptors are located in the skin
        
        info frm them is carried by
        cutaneous branches of the spinal nerves
        
        eg: touch
        pain
        pressure
        thermal (cold/warm)
    - - are carried by the
        muscular branches
        of the
        spinal or cranial nerves
        frm the deep body tissues
        
        eg: sensation of joints
        muscles & tendons
    - - are concerned with
        perception of internal environment
        
        are carried by the ANS
        
        eg: pain frm visceral structures
        conc of glucose in blood
  - - - are concerned with
        sensory perception
        at a distance
        
        eg: hearing
        vision
        smell
    - - are concerned with
        perception of
        external environment
        
        eg: touch
        temperature
        pain
        pressure
    - - 1.proprioceptors
        
        give info abt changes
        in position of the body
        in space
        -sp at the joints
        -or tension of muscle
        at any given moment
        
        include
        -muscle spindles
        -joint receptors
        -golgi tendon organs
        -vestibular receptors
      - respond to changes
        within the body itself
        & comprise of
      - 2.visceroreceptors
        
        Eg: baroreceptors
        osmoreceptors
        glucoreceptors
      - 3.chemoreceptors
