Sensation
What allows us to see color vision?
Cones
____________ is the minimum amount of stimulation needed to detect a particular stimulus.
Absolute threshold
The ______________ division of the autonomic nervous system arouses the body to deal with perceived threats.
sympathetic
Sound travels rapidly through the air in ____________.
waves
What is the part of a neuron that contains the nucleus and genetic information?
cell body or soma
______________ is the sense that tells you whether you are physically upright without the use of your eyes that allows you to keep your balance.
Vestibular
closure
The ___________ is the most important endocrine gland, known as the "master gland."
pituitary gland
The neurons that are in your brain and spinal cord that process information are called _____________.
interneurons
___________ is the sense that tells you the position and motion of your body.
Kinesthesis
The ________ is the gateway from the outer ear to the middle ear. It is a thin membrane that vibrates when sound waves strike it.
eardrum
________________ is the knowledge that an item has only one shape no matter what angle you view it from.
Shape constancy
Substances that boost the effects of a neurotransmitter are __________.
agonists
What causes color blindness?
absence or malfunction of cones
_________ refers to how high or low the sound is. It depends upon its frequency, or number of cycles per second.
Pitch
The ______________ transmits signals from the ear to the brain.
auditory nerve
Why do illusions occur?
because of your brain's use of perceptual constancies
The endocrine system is a set of glands that produce _________ that communicate information.
___________ is the stimulation of sensory receptors and the transmission of sensory information to the central nervous system.
Sensation
___________ is the transmission of characteristics from parents to offspring that plays a role in the development of our traits.
Heredity
The ___________ is the bony part of the inner ear that contains fluids and neurons.
cochlea
_____________ is the minimum amount of difference that can be detected between two stimuli.
Difference threshold
Which of the following choices lists some of the ways in which we study the nervous system?
A. creating lesions, brain imaging, questionnaires
B. accidents, brain recording, behavioral observation
C. brain imaging, electrically stimulating the brain, creating lesions
D. behavioral observation, brain imaging, analyzing blood
Define sensory adaptation and give an example of sensory adaptation in action.
Sensory adaptation is the process by which we become more sensitive to weak stimuli and less sensitive to unchanging stimuli. Example: Moving to a city from a rural area and getting used to the loud sounds in order to be able to sleep.
Describe, compare, and contrast sensation and perception. Why are both concepts necessary for us to make sense of our reality?
Sensation-raw sensory data. Perception-our brain adding meaning to the sensory data. Need both to properly inform our brain about the environment.
