Microanatomy
This type of neuron has many dendrites and one axon and is the most common type found in the nervous system.
What is a multipolar neuron?
This part of the neuron receives incoming signals and carries them toward the cell body.
What are the dendrites?
This brain tissue houses motor neurons and interneuron cell bodies, and unmyelinated axons.
BONUS if you can tell me if it's on the inside or the outside of the brain
The location of conscious thought and origin of intellectual function.
What is the cerebrum?
These 5 things protect the brain
What are bones, glial cells, meninges, CSF, and the blood brain barrier?
These cells make up 80% of the nervous tissue.
What are the supporting (glial cells)?
Bonus if you can give their 2 characteristics!!
These structures form the synapse.
What are the dendrites and axon terminals?
This brain tissue is made up of myelinated axons.
What is white matter?
BONUS (if not already answered): is this on the inside or outside of the brain?
This structure connects the two halves of the cerebrum and allows them to interact.
What is the corpus callosum?
There are four of these continuous cavities in the brain filled with cerebrospinal fluid.
These are the four glial cells in the CNS.
What are astrocytes, oligodendrocytes, microglia, and ependymal cells?
These are the four characteristics of a neuron.
What is electrical conductivity, extreme longevity, do not divide, and high metabolic rate?
These are the three components of the diencephalon.
What are the epithalamus, thalamus, and hypothalamus?
This marking separates the left and right cerebral hemispheres.
What is the longitudinal fissure?
The three meninges in order of superficial to deep.
What are the dura mater, arachnoid mater, and pia mater?
This structure on the neuron is found between the myelin sheath on the axon.
What are the nodes of Ranvier?
These neurons are found entirely within the central nervous system and are responsible for processing and integrating information between other neurons.
What are interneurons?
These are the 4 main components of the brain.
What are the cerebrum, diencephalon, cerebellum, and brain stem?
The cerebral cortex is divided into these 5 lobes.
What are the frontal, parietal, occipital, and temporal lobes, and the insula?
These three locations are where the blood-brain barrier is reduced.
What is the choroid plexus, the hypothalamus, and the pineal gland?
These 2 glial cells have the same role, making myelin; however, one acts in the CNS and the other in the PNS?
What are oligodendrocytes and Schwann cells (neurolemmocytes)
Describe the process of the chemical synapse. This does NOT need to be in question form.
Neurotransmitters are made and stored in vesicles. Next, the action potential arrives, causing the opening of Ca2+ channels, which allow neurotransmitter release from the presynaptic neuron. The neurotransmitters bind to the receptors on the postsynaptic neuron causing the opening or closing of channels. Then the neurotransmitters are removed from the synaptic cleft and the vesicular membranes are remade from the plasma membrane
This part of the brain is associated with balance and voluntary movement.
What is the cerebellum?
Within this folded/raised portion of the cerebrum, one can find the primary somatosensory cortex.
What is the postcentral gyrus?
These are the three functions of the clear fluid that circulates in the subarachnoid space.
What is buoyancy, protection, and environmental stability?
