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.

- Some sensory receptors, such as those for taste, smell, and pressure, readilyundergo the process of sensory adaptation,or decreased response to a stimulus. In contrast, receptors for pain are less prone to adaptation. Why does this make good biological sense? What do you think happens to children who are born without the ability to feel pain normally?arrow_forwardWhat is one organ, structure, sensory receptor that is present in an other animals and you wish you had. Describe it and explain whyarrow_forwardThe 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_forward
- Vertebrates have a wide range of sensory modalities. Which of the following was NOT present in early vertebrates? photoreceptors with different opsins to allow for color vision electoreception a vestibular aparatus containing calcium crytals enabling animals to detect which way is up vocalization or sound production fpr communicationarrow_forwardGiven that frogs are nearsighted in air, which statement is most likely to be true about their vision in water? (a) They are even more nearsighted; because water has a higher index of refraction than air, a frog’s ability to focus light increases in water. (b) They are less nearsighted, because the cornea is less effective at refracting light in water than in air. (c) Their vision is no different, because only structures that are internal to the eye can affect the eye’s ability to focus. (d) The images projected on the retina are no longer inverted, because the eye in water functions as a diverging lens rather than a converging lens.arrow_forwardMost animals lack cones in their retinas. How, then, do such animals view the visual world?arrow_forward
- Select the statement that best describes how the nervous system encodes sensory input. a. Neural coding permits precise assessments of the absolute intensity of a stimulus. b. Neural circuits in sensory systems are always convergent. c. The neural representation of sensory input is an exact replica of the physical world. d. The neural representation of sensory input emphasizes some sensory qualities over others. e. Each neuron must be optimized to code both resolution and sensitivityarrow_forwardHow could you study an animal’s senses to design a product for humans who are missing one of their senses? Answer in a few sentences.arrow_forwardWhat does it mean to say sense organs are transducers? What form of energy do all receptors have as their output?arrow_forward
- 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_forwardWhich sensory processing principle listed below best explains why we detect heat sensation when eating foods that contain capsaicin, the molecule found in chili peppers. a. Parallel processing. b. Labeled lines. c. Topographic maps. d. Efferent modulation . e. Neural plasticity.arrow_forwardWhich of the following best describes the function of a camera type eye? A) To form high-definition images that are transmitted to the brain. B) To gather and concentrate light through a lens onto retinal tissue which generates an impulse that is transmitted to the brain. C) To protect the optic nerve which generates an impulse that is transmitted to the brain. D) To detect vibrations through the vitreous body which generates an impulse that is transmitted to the brain.arrow_forward
