Comprehensive Neuroscience Q&A Exam Bundle

1. The neuron doctrine states that a) Neurites are fused together to form a continuous network b) Neurites are not continuous and communicate by contact c) Neurons must contain a soma, an axon, and dendrites d) DNA is transcribed to mRNA which is translated into protein b) Neurites are not co...

Diffusion: A. Carries particles away from equilibrium B. Requires energy c. occurs due to random motion of particles d. is a type of active transport e. only occurs in biological systems c. Diffusion occurs due to random motion of particles The Nernst equation a. Calculates equilibrium pote...

None of the above = pons To relay the sensory information to the cerebellum and thalamus and contain viscera somatic and motor C Which of the following are true about the CEREBELLUM? a. the cerebellum relays information to the thalamus b. relay c. coordinate complex motor behaviors Myelenc...

myelin sheath covers the axon of some neurons and helps speed neural impulses Axon transmits information from the soma to other cells in the body. soma determines if the neuron will send message nucleus biochemical information to keep neuron functioning dendrites receive messages from ot...

Synapses transmit... info across neuron to neuron motoneurons large w/ large axons to stimulate muscles sensory neurons respond to environmental stimuli (such as touch, odor) interneurons connectors - send and receive input to other neurons What are the three types of neurons? motoneuron...

Glia Cells in the nervous system that support the activities of neurons Neuron A cell of the nervous system that is specialized for information processing and communication Macroglia Large glial cells Astrocyte Structural support, nourishment, endfeet (blood-brain barrier), support and form...

What makes up the central nervous system? Brain and spinal cord What makes up the peripheral nervous system? CN and ganglia Spinal nerves and ganglia Enteric nervous system Sympathetic and parasympathetic What are the 5 steps of embryological development of the nervous system? Neurula...

Action potential The electrical signal conducted along axons (or muscle fibers) by which information is conveyed from one place to another in the nervous system Afferent A neuron or axon that conducts action potentials from the periphery toward the central nervous system. Anterograde Signals o...

Where does neuroscience find itself in psychology and biology? What is neuroscience? right in the middle between psych and biology, it is the intersection of biology and psychology. We use the biological bases to understand psychological processes and vice versa. Stuying the function and structure o...

neurons a nerve cell, the basic building block of the nervous system neurons these help us understand our thoughts and actions, memories and moods. all neurons consist of a cell body and its branching fibers!! dendrite a neurons bushy, branching extensions that receive messages and conduct imp...

Neuroscience scientific study of the nervous system. Axon The neuronal process that carries the action potential from the nerve cell body to a target Axons respond to attractants and repellents which may be diffusible or substrate bound. Dendrite a neuronal process arising from the cell body t...

Neuropsychology the branch of psychology that is concerned with the physiological bases of psychological processes Lesioning in studies of brain functioning, the intentional destruction of brain tissue in order to observe the effects on behavior Stereotaxic apparatus A device used to insert an...

genomics focuses on the analysis of complete DNA sequences, both coding and regulatory. gap junctions intercellular continuities between neurons that allow for cytoplasmic continuity and the direct transfer of electrical and chemical signals between cells in the nervous system dendrites the pr...

Major components of the nervous system Central nervous system (CNS) = brain and spinal cord Peripheral nervous system (PNS) ∙spinal nerves (31 pairs) arise from spinal cord → sensory/motor ∙cranial nerves (12 pairs, all but first arise from brain) are largely concerned with motor and sens...
