Summary Introduction
Introduction:
All sense organs eventually derive their information from sensory receptor cells that identify stimuli. There are several types of sensory receptors such as mechanoreceptors, which respond to physical stimuli; thermoreceptors, which respond to temperature; pain receptors, which identify tissue damage; and chemoreceptors, which detect chemicals.

As you snuggle into bed, you feel the weight of the blankets on yourbody, but you soon become unaware of the covers. What hashappened?a. Your skin’s touch receptors have become unable to receiveinformation about new stimuli.b. Your skin’s touch receptors have adapted to the feeling of theblankets.c. All of your body’s sensory receptors have become unable toreceive information about new stimuli.d. All of your body’s sensory receptors have adapted to the feeling ofthe blankets
If a person is born blind, in what way do the senses of hearing and touch improve? a. The person gradually develops more receptors in the ears and skin. b. The number of receptors does not change, but each of them becomes more responsive to weak stimuli. c. The receptors in the ears and skin send faster action potentials to the brain. d. Through practice the person learns to increase attention to hearing and touch, and those sensations come to activate the occipital cortex.

- What is meant by blindsight? a. Some people with damage to the primary visual cortex accurately guess the location or other properties of objects they say they don’t see. b. Blind people learn to find their way around by making sounds and listening for echoes. c. Blind people on average develop enhancements of hearing, touch, and other senses. d. After damage to the eyes, other body parts become sensitive to light. e. Incorrect hindsight.arrow_forwardIf a kitten has one eye shut for its first few weeks of life, its visual cortex becomes insensitive to that eye. Why? a. The receptors die. b. Any axon that is not used for that long becomes unable to respond. c.

It reaches the left half of each retina, which sends messages to the left hemisphere.D. It reaches the left half of each retina, which sends messages to the right hemisphere.arrow_forward
- What function do the malleus, incus, and stapes bones in the inner ear play in processing sounds? A. The bones transform pressure waves into nerve impulses that the brain recognizes as sound. B. The bones equalize pressure between the middle ear and the atmosphere. C. The bones transmit vibrations to the oval window setting the fluid in the cochlea in motion. D. The bones depolarize or hyperpolarize hair cells depending on the direction they vibrate.arrow_forwardThe transduction process of converting light into neural signals sent to the central nervous system involves which of these steps? A. Bipolar Cells collect signals from Rods and Cones. B. The Optic Nerve carries signals about light from the Lateral Geniculate Nuclues to the Retinal Ganglion Cells. C. Retinal Ganglion Cells relay information to Rods and Cones. D.

What effect, if any, might his cold have on his sense of taste? a. His sense of taste will be increased since he isn’t receiving additional sensory input from his smell. b. His sense of taste will be dulled since taste and smell often work together. c. His sense of taste will get better but not until 48 hours after he loses his sense of smell. d. His sense of taste will be no better or worse since the senses of taste and smell are completely separate.arrow_forward
