Summary Introduction
Introduction: The human body’s sensory structures gather information and pass it on to the central nervous system (CNS). The sensory organs are in pairs such as two eyes and two ears. Action potentials from sensory receptors travel along the neurons. These neurons form synapses in the brain or spinal cord. As a result, the brain recognise stimuli, such as sight and sound along with the action potentials have arrived.
Proposed hypothesis: The eye change to aid our vision in different situation with left eye open, right eye open, and both eyes open.

Ture or False:(T/F) A bee would detect the odor of the flowers using trichoid sensilla located on the antennae and the olfactory information would be processed in the glomeruli of the deuterocerbrum and incorporated into olfactory learning in the corpora pedunculata of the protocerebrum.(T/F) A bee would monitor and control flight speed using interommatidial hairs and the optomotor response.(T/F) Stresses and strains on the exoskeleton during flight would be monitored by basiconic and coeloconic sensilla located in the wing hinge.

The following passage comes from an abstract in a study about analyzing hearing
loss in twins:
"A clinical and genetic study on 25 twin pairs with at least one deaf member was
performed. Concordance rate of hearing loss was 0.88 in MZ and 0.50 in DZ pairs"
(MZ =monozygotic or identical twins. DZ -Dizygotic or fraternal twins). From this
data alone, what can you conclude about the roles of environment and genetics in
hearing loss? Explain how you reached your conclusion.
Include a 5-10 sentence explanation of how the sheep’s eye senses light and relays that data to the brain to interpret visual information. Some pieces to consider:
What path does the light travel?
What structures and pigments does it interact with?
How does the signal travel to the brain?
Where in the brain is the data processed?
How is this different in the high light vs low light?
How might the sheep’s vision differ from our own?

- Like other nocturnal carnivores, the ferret shown in FIGURE 33.13 has light-reflecting material in its choroid. Explain why the presence of reflective material in this layer of the eye maximizes the degree to which light excites photoreceptors. Explain also why having reflective material in this layer causes the perceived image to be somewhat blurry.

A difference between the vertebrate eye and the cephalopod eye is that the vertebrate eye has: a. an iris surrounding the pupil, whereas in cephalopods the pupil surrounds the iris. b. a lens that changes shape when focusing, whereas in cephalopods the lens moves back and forth to focus. c. a retina that moves in the socket when recording the image, whereas in cephalopods the retina changes shape when stimulated. d. a pupil that shrinks in size in bright light, whereas cephalopods have a pupil that enlarges in bright light. e. retinal synthesized from vitamin A, whereas cephalopods lack retinal.arrow_forwardplease asap. thanku You discover a new species of frog in extremely dark parts of the Amazon rain forest.

- Which of the following statements about sensory systems is NOT true? a. Sensory transduction involves the conversion (by either a direct or indirect mechanism) of a physical or chemical stimulus into changes in membrane potential difference. b. Sensory adaptation plays a role in the ability of organisms to discriminate between important and unimportant information. c. The term "sensory adaptation" refers to the process by which a sensory cell becomes less sensitive, or less responsive, to a continuing source of stimulation. d. In general, a stimulus causes a change in the flow of charged ions across the plasma membrane of a sensory receptor cell. e. The more intense a stimulus is, the greater the peak depolarization of the action potentials fired by the sensory neuron.arrow_forwardSelect the statement that best describes how the nervous system encodes sensory input. a.

- The function of the vertebrate eye is unusual compared with other processes found within the body. For example, the direction in which sensory information flows is actually opposite to the path that light takes through the retina. Explain the sequence of events involved in the movement of light and information through the structures of the eye and explain why they move in opposite directions. Compare this sequence to the functioning of the Mollusk eye.arrow_forwardReview the summary of a published scientific study below: Patients with multiple sclerosis frequently suffer from blurred vision. Drug X was developed to reduce blurred vision in healthy patients, but the effectiveness had not been tested on those suffering from multiple sclerosis. A study was conducted to determine if Drug X is effective at reducing blurry vision in multiple sclerosis patients. To be considered effective, a drug must reduce blurred vision by more than 30% in patients. Researchers predicted that a 20 mg dose of the drug would be effective for treating blurred vision in multiple sclerosis patients by reducing blurred vision by more than 30%. Drug X was administered to groups of multiple sclerosis patients at three doses (10 mg/day, 20 mg/day, 30 mg/day) for three weeks. A fourth group of patients was given a placebo containing no drug X for the same length of time. Vision clarity was measured for each patient before and after the three-week period using a standard…arrow_forwardDistinguish between static and dynamic equilibrium. The sense of equilibrium (balance) is really two senses— static equilibrium and dynamic equilibrium—that come from different sensory organs. The organs of static equilibrium (stat′ik e″kwı˘-lib′re-um) sense the position of the head, maintaining balance, stability and posture when the head and body are still. When the head and body suddenly move or rotate, the organs of dynamic equilibrium (di-nam′ik e″kwı˘- lib′re-um) detect such motion and aid in maintaining balance.arrow_forward
