The Nervous System
This part of your nervous system is sometimes referred to as the "rest and digest" system
parasympathetic
These cells are responsible for supporting neurons, playing a role in nourishing and protecting them. They make up the myelin sheathe
Glial cells
While studying the brain, a student learns about the lobe responsible for visual processing. Which lobe is primarily involved in this function?
Occipital lobe
List the sleep stages
1, 2, 3, Rem
The smallest change in the intensity of a stimulus that can be detected is referred to as:
Just noticeable difference or difference threshold
A sensory neuron is also know as this type of neuron, that begins with an "a"
Afferent
In an experiment on neural firing, a neuron is stimulated to the point of action potential. After the neuron fires, there is a brief period when it cannot fire again regardless of the strength of the stimulus. What is this period called?
Refractory Period
A researcher is studying the brain and wants to understand how different parts communicate. She decides to sever the large bundle of fibers connecting the two hemispheres. Which of the following structures is she most likely studying?
The corpus callosum
. An individual experiences disruptions in their sleep-wake cycle due to irregular work hours. Which biological process is likely affected?
Circadian Rhythm
What are the six tastes?
sweet, sour, bitter, salty, umami, oleogustus
These are neurons within the brain and spinal cord that communicate internally and process information between sensory inputs and motor outputs
interneurons
A person takes a drug that binds to opioid receptors but does not activate them, instead blocking other substances from binding. This drug is best described as a(n):
Antagonist
These are areas of the cerebral cortex that are not involved in primary motor or sensory functions, but rather involved in higher mental functions such as learning, remembering, thinking, and speaking
Association areas
A patient experiences repeated episodes where breathing stops during sleep, leading to frequent awakenings. This condition is known as:
Sleep apnea
The process by which the brain determines the location of a sound source based on differences in timing and intensity is called:
Sound localization
Take me through the steps of the reflex arc
Sensory neuron receives input and sends it to
interneurons which process that information and send it to
Motor neurons, which react to the stimulus
This neurotransmitter is responsible for enabling muscle action, learning, and memory. When the neurons that produce this neurotransmitter deteriorate, it can cause Alzheimer's disease.
Acetylcholine
This curved structure in the brain processes conscious, explicit memories.
Hippocampus
Alpha and Beta
In the retina, which type of cells receive input from photoreceptors and transmit information to the brain?
Ganglion Cells
Draw and label the main sections of the nervous system
CNS-PNS
Autonomic-Somatic (sensory-motor)
Sympathetic- Parasympathetic
Draw and label the basic parts of a neuron
Soma, dendrite, axon, terminal branches of axon
This is the region at the front of the parietal lobes that registers and processes body touch and movement sensations
Somatosensory cortex
According to which theory, dreams are the brain's attempt to make sense of random neural activity during sleep?
Activation-Synthesis Theory
Which theory proposes that groups of neurons in the auditory system respond to sounds by firing action potentials slightly out of phase with one another, so that when combined, a greater frequency of sound can be encoded?
Volley theory
