Sensory Receptors - classification Flashcards
The nervous system uses _____ receptors to detect the state of the internal and external milieu.
sensory
The 3 methods of classifying sensory receptors are:
- Anatomical location of the stimulus
- Type of stimulus
- Complexity of the structure
Exteroceptors are located on the surface of the body, and they receive information about the _____ environment
external
Exteroceptors receive information from the environment for the sense of: (8)
- Hearing
- Vision
- Smell
- Taste
- Pressure
- Vibration
- Temperature
- Pain
Visceroceptors are located in the ____ ____ and ______ ______
Blood Vesssel
Internal Organs
Visceroreceptors provide information for the _______ control of the internal milieu.
autonomic
Visceroceptors can provide information to the autonomic nervous system without requiring the involvement of the conscious areas of the
True or False
True
There is an exception to which the visceroecptors can stimulate the ANS without conscious involvement of the CNS. This exception is painful stimuli because painful stimuli will produce _____ pain to the body surface
referred
Proprioceptors are loacted in the muscles and the articulations to provide information about ____ of the body.
Posture
The sensory receptors classified by the type of stimulus are: (5)
