Anatomy and Physiology of Special Sensory Organs

Sensory organs can be labeled as special sensory structures that permit sight, hearing, odor, and flavor. Sensory structures permitting proprioception, touch, thermal, and pain perception can be classified as more advanced sensory organs. The sensory neu…

Sensory Receptors

The human sensory system is one of the most complex and highly evolved structures, which processes a myriad of incoming messages. This well-coordinated system helps an organism or individual to respond to external stimuli, appropriately. The sensory rece…

Textbook Question

Chapter 16, Problem 6ILQ

Watch this video (http://openstaxcollege.org/l/2point) to see a quick demonstration of two-point discrimination. Touching a specialized caliper to the surface of the skin will measure the distance between two points that are perceived as distinct stimuli versus a single stimulus. The patient keeps their eyes closed while the examiner switches between using both points of the caliper or just one. The patient then must indicate whether one or two stimuli are in contact with the skin. Why is the distance between the caliper points closer on the fingertips as opposed to the palm of the hand? And what do you think the distance would be on the arm, or the shoulder?

When a person blinks, the part of the brain that interprets visual stimulation is suppressed. The spontaneous act of blinking is controlled by the area of the brain that controls involuntary movements such as breathing and blood pressure. To determine whether the lack of light or the act of blinking causes the suppression, scientists had subjects close their eyes and then placed a bright flashing light in their mouth to stimulate the photoreceptors in the eyes through the palate. Visual stimulation was still suppressed. So the photoreceptors in the retina were not stimulated even though they were exposed to light. This study demonstrated that when a person blinks, it is the act of blinking and not the absence of light that causes the suppression of visual stimulation. In the diagram above, identify the part of the brain that is suppressed during blinking and the part of the brain that controls involuntary, spontaneous blinking. Select one: a. 3 and 8 b. 2 and 9 c. 5 and 6 d. 1…

Then, analyze the following hypothetical situation: Cassey Madrid is a medical assistant at a medical office. He is testing visual acuity in patients for the first time and feels nervous about it. However, Cassey remembered when he did it in his clinical procedures class, so he takes a deep breath and calls the patient, Mr. Saleto. After identifying the patient and welcoming him in the room, Cassey explains the procedure to Mr. Saleto. What should be the distance between Mr. Saleto and the Snellen chart? What instructions can Casey give to Mr. Saleto if he uses glasses? By using the Snellen chart, is Cassey testing distance or near visual acuity? What does it mean if the result of the test is 20/60? What are some nonverbal cues that may indicate that the patient is having difficulty reading the line to which Cassey is pointing?

From a biological perspective, how do our senses monitor our body's position and movement? Discuss factors which may influence our vestibular senses. Include a relevant example. Please include references.
