Wearing eyeglasses for a prolonged period of time and then not realizing they are on your head is vest explaining of ........ Stimulus transduction  Phasic receptors potential  Sensory adaptation  Phasic sematoreception

What are the vision and audition receptor cells?  What are the olfaction and gustation receptor cells? Differentiate between these homeostatic imbalances of the eye: myopia, hyperopia, glaucoma, cataracts, macular degeneration

Why can tactile stimulus be localized in parts of our body better than other parts?

Actin and myosin in the sarcomeres will remain Douna. O Actin and myosin in the sarcomeres are in the unbound state. Question 41 Which of the following is an example of sensory adaptation? O After the wound healed, the pain also went away. O You notice the smell of liver and onions cooking when you enter the kitchen, but soon you do not notice the odor although they are still cooking. When it is totally dark, the rods and cones of the eyes do not send any visual impulses. O The act of trying to read a book while riding in a car causes eyestrain. Question 42 What determines "loudness"? O The number of hair cells that are stimulated. O The wave frequency or number of vibrations per second. O As the noise gets louder, the auditory (Eustachian) tube expands. 1 pts 1 pts

In the process of sensory coding    Recruitment of additional neurons occurs with a weak stimulus in order to make the stimulus stronger.   The larger the receptive field of a sensory receptor, the greater the expected acuity and the more accurate the two-point discrimination.    Lateral inhibition of neighboring receptors resulting in a relative reduction of action potentials in the neighboring second order neurons would be expected to increase acuity.   A receptor potential that remains suprathreshold into the absolute refractory period will result in additional action potentials.

Match the following statements to the type of cell in the eye each describes (rods or cones). Select "Both" if the statement is true of both cell types. Rods Directly detects light coming into the eye. Different types of this cell Cones respond to different wavelengths (colors) of light. More sensitive to low levels of light. Rods Found in high concentrations at the fovea centralis. Cones < <

Linear acceleration, such as the forward movement of being in a car, will result in Depolarization or hyperpolarization of hair cells within the utricle and saccule. Tonic release of neurotransmitters in the cochlea. Depolarization of hair cells within the semicircular canals. two of the above are correct

Julie Rogers, a 47-year-old patient, calls her physician’s office after leaving her workplace because she quite suddenly felt very tired and nauseated and noticed that her urine was dark. An associate at her workplace told Julie that the sclera of her eyes looked “yellow.” When she contacted her physician, she was told to come directly to the physician’s office for evaluation. When she arrived, as a precaution, Julie was taken to an exam room reserved with a protocol for strict infection control. Her vital signs were temperature 101.6, pulse 94, respirations 26, and blood pressure 148/88. Julie stated that her muscles felt sore. A urine specimen was collected and sent to the laboratory. On physical examination, liver enlargement was noted, as well as mild jaundice of the sclera. Julie’s clinical history was unremarkable, except that she mentioned that she had recently spent time at summer camp as a youth counselor. During this time, she was living in close quarters.   Hepatitis was…

Which of the following correctly describes receptors in the skin? Select one: O a. All receptor types are spread uniformly throughout dermal tissue. Ob. Pacinian corpuscles, Ruffini endings, and Krause end bulbs detect pain. O c. One type of nerve cell detects both hot and cold. O d. Temperature receptors are free nerve endings in the dermis. Oe. Meissner corpuscles and Merkel disks detect fine touch.

Can we have somatosensory receptors in other organs of the body besides the integument? Explain.
