A division of ANS that produces fight or flight response.	Sympathetic Division
A division of ANS that happens after adrenaline rush (rest and repair)	Parasympathetic Division
A type of cell in the nervous system that is capable of regeneration. Cell that supports and cushions the neuron. But it is not efficient when it comes in transmitting nerve impulses.	Neuroglia
A type of cell in the nervous system that is responsible for transmitting nerve impulses, transmission of action potentials. However, once damaged, it can no longer regenerate	Neuron
It is a neuroglia in the CNS that serves as a blood retinal barrier. It also plays a vital role in regulating the substances that are moving inside and outside of the retina.	Astrocyte
Cells that are lining the ventricles or cavities of the brain.	Ependymal Cell
A type of ependymal cell that produces CSF	Non-ciliated ependymal cells-choroid plexus
A type of ependymal cell that helps CSF flow throughout the brain.	Ciliated Ependymal Cells
These are macrophages that are found in the CNS	Microglia
It forms the myelin sheath in the CNS	Oligodendrocyte
A neuroglia in the PNS that forms the myelin sheath.	Schwann Cell
Another term for the myelin sheath that is formed in the PNS. It is capable of regenerating once damaged.	Neurilemma
A neuroglia in the PNS that supply nutrients to the surrounding neurons and have some structural functions.	Satellite Cell
It is a cell that is highly specialized in nerve impulse transmission.	Neuron
A type of neuron which transmits impulses from the receptor to the CNS.	Sensory/Afferent Neuron
A type of neuron which transmits impulses from the CNS to the effectors (muscles and glands).	Motor/Efferent Neuron
A type of neuron which analyzes. A neuron that is in between of efferent and an afferent neuron.	Association/Interneuron
A type of neuron where the soma is located on the periphery. Amacrine and horizontal cells in the retina are examples.	Pseudounipolar
A type of neuron that consists of one axon and one dendrite. The cell body is in the middle. Bipolar cells in the retina are an example.	Bipolar
These type of neuron is common in the brain and the spinal cord. Ganglion cells in the retina are an example.	Multipolar
Its also known as nerve impulse. Wave of electrical fluctuation that travels along neuron's plasma membrane.	Action Potential
What type of action potential conduction is in a myelinated axon. It is as if jumps from one node of Ranvier to another.	Saltatory Conduction
T or F: Myelinated neurons have slow transmission action potentials	false
T or F: Unmyelinated neurons have fast transmission of action potentials.	false
It is a junction where the axon of one neuron interacts with another neuron or an effector. It consists of a presynaptic terminal, synaptic cleft and postsynaptic membrane of another neuron or effector.	Synapse
A layer of the retina that contains axodendritic synapses between the photoreceptor cells and dendrites of bipolar and horizontal cells.	Outer Plexiform Layer
A layer of the retina that contains axodendritic synapses between axons of bipolar neurons and dendrites of ganglion cells and amacrine cells.	Inner Plexiform Layer
It is the largest and most complex tissue of the nervous tissue. Pinkish gray in color and weighs over 3lbs. It is situated inside of the cranium.	Brain
A major region in the brain that is divided by right cerebral hemisphere and left cerebral hemisphere.	Cerebrum
This hemisphere utilizes creativity. (arts, music, etc.,)	Right cerebral hemisphere
This hemisphere utilizes logical thinking (has good memory)	Left cerebral hemisphere.
The hemispheres in the cerebrum are connected by?	Corpus Callosum
Intestine-like convolutions in the brain are called?	Gyri or Gyrus
If a gyri is shallow, it is called as?	Sulcus
If a gyri is deep, it is called as?	Fissure
A lobe in the cerebrum that is concerned with motor areas that control movements of the skeletal muscles. Its association areas carry on higher intellectual processes. (we usually rub in this area when we are thinking of something)	Frontal Lobes
A lobe in the cerebrum where its sensory area is for the sensation of temperature, touch and pain. Its association area functions in understanding speech and in using words to express thoughts and feelings. (People with very good deliveration of words)	Parietal Lobes
A lobe in the cerebrum where its sensory areas is concerned with auditory and olfactory. Its association areas function in interpreting sensory experience and in remembering visual scenes, music, and other complex sensory patterns. (LSS, people with photographic memory)	Temporal Lobe
A lobe in the cerebrum where its sensory areas is concerned with vision. Its association areas function in combining visual images with other sensory experiences. It is also where visual cortex is situated.	Occipital Lobe
It is in the area of occipital lobe which is important in interpreting the visual information transmitted in the retina.	Visual Cortex
Frontal lobe can store _______	Short Term Memory
A portion in the temporal lobe can store _______	Recent Memory
Cerebral cortex can store _______	Long-term memory
