Concept explainers
To determine:The senses that are being tested by probing needle.
Introduction: The largest sense organ in the body is skin. It is present as a covering throughout the body of a living organism. The skin has various types of receptors that are stimulated under different conditions, like pain, itch, touch, warmth, and so on.
To determine: The receptors that are stimulated while probing needles in an individual.
Introduction: Skin is the largest largest sense organ of the body. It is the all over covering of the body of an organism. The skin has several types of receptors which are are stimulated under different conditions like warmth, pain, itch, touch, and so on.
To determine: The reason due to which the individual feels only one probe even though the individual is stimulated by two needle probes.
Introduction: The autonomic nervous system (ANS) helps in maintaining a steady state in the internal environment, which is called homeostasis. The two branches of ANS are the sympathetic nervous system and parasympathetic nervous system. These systems control the different responses to different stimuli.

- Bryan has normal vision and is wearing a special headset that shows a picture of a sailboat to his left eye and a picture of a dog to his right eye. What is Bryan's perception of these images most likely to be? He will only perceive whichever image is presented to his dominant eye. He will alternate between perceiving the sailboat and perceiving the dog. He will perceive the dog and the sailboat overlaid on top of each other. He will perceive parts of the dog and parts of the sailboat combined together in a fashion similar to a puzzle.arrow_forwardWhat type of cutaneous receptor enables you to feel an insect crawling through your hair? What type enables you to palpate a patient’s pulse? What type would give you a feeling that your belt is too tight?arrow_forwardYour friend had a severe infection in the cochlea, which caused deafness. The scarring from the infection prevents movement of the basilar membrane of the organ of Corti. In response to a sound, you would predict that: The tympanic membrane would not vibrate The tympanic membrane would vibrate but the three bones in the middle ear would not move The three bones in the middle ear would move, but the cochlear fluid would not have any waves The cochlear fluid would have waves, but the hair cells would not bend The hair cells would bend, but no receptor potential would be createdarrow_forward
- Let us say if someone electrically stimulated the auditory receptors in your ear, what would you perceive?arrow_forwardAfter an experiment on the somatic senses: superficial sensory modalities, Trace the pathways for transmission of light touch sensation from the specific sensory receptors to the sensory cortex. What may be potential causes for incorrect identification in this sensory test of the subject?arrow_forwardPeripheral senses are also involved in proprioception and let us know where our body parts are in space. What are these sensors and how do they work?arrow_forward
- Fill out the information indicated for tactile receptors in the table below: Name Structure Location Function. (encapsulated or unencapsulated?) Tactile disc Tactile corpuscle Free nerve endings End bulb Bulbous corpuscle Root hair plexus Lamellated corpusclearrow_forwardA tumor has destroyed the areas of a patient’s thalamus that are part of the special senses pathways. Which special sensewill not be affected, and why? Explain why the patient has no conscious awareness of the remaining special sensesarrow_forwardWe discussed three principles with regards to the sensory cortex (mechanisms of perception), with one of them being a hierarchical organization. Using the somatosensory system as an example (specifically the exteroceptive part of that system), state each level of the hierarchy with regards to this system, beginning with the one at the lowest level of the hierarchy to the final uppermost level. give the name at each level as it corresponds with this system.arrow_forward
- Pain Undergoes little, if any, sensory adaptation. Why do you think this is so important?arrow_forwardHow is The vestibular sense important in nursing practice?arrow_forwardDraw a simple (typical of somatic senses) and a complex (typical of special senses) sensory neuron (receptor). Where applicable, label the cell body, the axon, the nerve endings, myelin, and the axon terminal.arrow_forward
