Part of the PNS, picks up messages from the nerves and relays the information to the brain via spinal cord
Block or disallow reuptake of neurotransmitters
Parkinson's Brains lack this, Schizophrenic patients' brains have excess
the minimum level of stimulation required to fire a neuron
a pair of endocrine glands that sit just above the kidneys and secrete hormones that help arouse the body in times of stress
2 lima bean sized neural clusters in the limbic system; linked to emotion
the part of the peripheral nervous system that controls the glands and the muscles of the internal organ. Its sympathetic division arouses, its parasympathetic division calms.
Autonomic Nervous System
the neuron extension that passes messages through its branches to other neurons or to muscles or glands
Brain and Spinal Cord
Central Nervous System (CNS)
The little brain at the rear of the brainstem. Processes sensory input
the large band of neural fibers connecting the 2 brain hemispheres and carrying messages between them
a neurons bush, branching extensions that receive messages and conduct impulses towar the cell body.
The bodys slow chemical communication system; a set of glands that secrete hormones in the blood stream
Chemical messengers that are manufactured by the endocrine glands. They travel through th blood stream and affect our tissues
a neural structure lying below the thalamus; it directs sever maintenance activities, helps govern the enodcrine system via the pituitary gland, the end is linked to emotion and reward
an are at the rear of the frontal lobe that controls voluntary movements
a fatty tissue layer segmentally enclosing the axons some neurons. It speeds up the transmission of a neural impulse.
a nerve cell, basic building blocks of the nervous system
Division of ANS that calms the body, conserving energy
Peripheral Nervous System (PNS)
the endocrine systems most influential gland. Under the influence of the hypothalamus, regulates growth, and controls endocrine glands
Encompasses part of the visual cortex, coordinates difficult activities such as multi tasking or playing music?
chemical messengers that cross the synaptic gaps between neurons. When released by the sending neuron, they travel across the synapse and bind to receptor site on the receiving neuron, there by influencing whether that neuron will generate a neural impulses.
a nerve network that travels through the brainstem and plays an important role in controlling arousal.
area at the front of the parietal lobes that registers and processes body touch and movement sensations
a 2 way information highway connecting between the peripheral nervous system and the brain
division of the autonomic nervous system that arouses the body, mobilizing its energy in stressful situation
Sympathetic Nervous System
meeting point between neurons
the brains sensory switchboard, located on top of the brainstem; it directs messages to the sensory receiving areas in the cortex, transmits replies to the cerebellum and medulla.
controls the bodys metabolism
interoperates and makes sense of what you hear
influences movement, learning, attention, and emotion. Lack of it is found in parkinsens, excess is found in schizophrenia
affects mood, hunger, sleep, and arousal, lack of leads to depression
enables muscle movement, learning and memory.
natural opiates, like neurotransmitters they are linked to pain control and pleasure
a neural impulse, a brief charge that travel down the axon
Part of the PNS that controls the glands and muscles of the internal organs
Autonomic Nervous System
form junctions with other cells
a neural center located in the limbic system; helps process explicit memories for storage
portion of the cerebral cortex lying at the back of the head; areas the receive information from the visual fields
portion of the cerebral cortex lying at the top of the head and toward the rear; receives sensory input for touch and body input
an organ of soft nervous tissue contained in the skull of vertebrates, functioning as the coordinating center of sensation and intellectual and nervous activity
potion of the cerebral cortex lying roughly above the ears; includes the auditory areas, each receiving information primarily from the opposite ear
modulates our speech, orchestrates our sensee of self, helps with perceptual tasks
life support center
soma cell body
a fluid- or air-filled cavity or sac, in particular
