Quicksheets Flashcards
What are the three types of neurons in the nervous system? Are they afferent or efferent?
- Motor (efferent)
- Interneurons
- Sensory (afferent)
What is the difference between the sympathetic and parasympathetic nervous systems? What is the relative location of the nerves associated with them?
Sympathetic: “Fight or Flight” responses; mostly located between T1 and T12 of the spinal cord.
Parasympathetic: “Rest and Digest” Responses; mostly located in upper and lower spinal cord

What are the subcategories of the autonomic nervous system?
Sympathetic Nervous System: This division of autonomic nervous system is responsible for controlling fight or flight response. It controls the involuntary responses of the body when a person is in some serious situation. The sympathetic responses prepare the body to deal with some fight or flight conditions.
Parasympathetic Nervous System: This division controls the body functions in a calm state. The involuntary responses of the body under calm conditions are controlled by the parasympathetic nervous system. It is responsible for regulating body functions under normal conditions.
Enteric Nervous System: It is the third division of the autonomic nervous system. It is confined to the control of the gut. It contains branches from both sympathetic and parasympathetic nervous systems and is responsible for regulating the functions of gastrointestinal tract.
What are the roles of the parasympathetic nervous system? The sympathetic nervous system?

What are the 3 main categories for “organization of the brain”? What do each of them contain?
- Hindbrain:
- Cerebellum
- Medulla Oblangata
- Reticular formation
- Midbrain
- Inferior colliculi
- Superior colliculi
- Forebrain
- Thalamus
- Hypothalamus
- Basal Ganglia
- Limbic system
- Cerebral Cortex

What part of the brain does the thalamus belong to? What is its role?
The thalamus belongs to the forebrain
It is the “relay station” for sensory information

What part of the brain does the hypothalamus belong to? What is its role?
The hypothalamus belongs to the forebrain.
It maintains homeostasis and integrates with the endocrine system through the hypophyseal portal system that connects it to the anterior pituitary.

What part of the brain does the Basal Ganglia belong to? What is its role?
The basal ganglia belongs to the forebrain
It smoothens movements and helps maintain postural stablility

What part of the brain does the limbic system belong to? What is its role? What are the major subgroups of the limbic system?
The limbic system belongs to the forebrain.
Controls emotion and memory.
Includes the septal nuclei (pleasure seeking), the amygdala (fear and aggression), hippocampus (memory), and fornix (communication with limbic system)
What are the 4 lobes of the cerebral cortex?
- The frontal lobe
- The parietal lobe
- The occipital lobe
- The temporal lobe

What is the role of the frontal lobe?
What larger area of the brain is it a part of?
The frontal lobe:
Executive function
impulse control
long-term planning (prefrontal cortex)
Motor function (primary motor cortex)
Speech Production (Broca’s area)
Subcategory of cerebral cortex

What is the role of the parietal lobe?
What larger area of the brain is it a part of?
Parietal Lobe:
Sensation of touch, pressure, temperature, and pain (somatosensory cortex)
Spatial processing, orientatation, and manipulation
Part of the cerebral cortex
What is the role of the Temporal lobe?
What larger area of the brain is it a part of?
Temporal Lobe:
Sound processing (auditory cortex)
Speech perception (Wernicke’s area)
Memory and emotion (limbic system)

What is the role of the occipital lobe?
What larger area of the brain is it a part of?
Occipital Lobe:
Visual Processing
What is the role of acetylcholine?
Voluntary muscle control
Parasympathetic nervous system
Attention
Alertness

What is the role of epinephrine and norepinephrine?
Fight-or-Flight
Wakefullness
Alertness

What is the role of dopamine?
Smooth movements
Postural stability

What is the role of serotonin?
Mood
Sleep
Eating
Dreaming

What is the role of GABA, Glycine?
Brain “stabilization”

What is the role of glutamate?
Brain “excitation”

What is the role of endorphins?
Natural Painkillers

What is nature vs. nurture?
What type of studies are used to reseach it?
Nature vs. Nurture is a debate regarding the contributions of genetics (nature) and the environment (nurture) to an individual’s traits.
Family, twin, and adoption studies are used to study nature vs. nurture
What is the difference between sensation and perception? How is it involved in the nervous system? (3 major ways)
The conversion of physical stimuli into neurological signals in sensation while perception is the processing of sensory information to amke sense of its significance.
Sensory Receptors: respond to stimuli and trigger electrical signals.
Sensory Neurons: transmit information from sensory receptors to the CNS
Sensory stimuli: are transmitted to projection areas in the brain, which further analyze sensory input
What is Weber’s Law?
States that the just-noticeable difference for a stimulus is proportional to the magnitude of the stimulus, and this proportion is constant over most of the range of possible stimuli
