Brain

| getting information back out of our brains | ||
| (at the top and to the rear) percieves sensory input for touch and body position. | ||
| an area at the rear of the frontal lobes that controls voluntary movement | ||
| directs messages to the sensory recieving area in the cortex and transmits replies to the cerebellum and medulla | ||
| nerve cells that consist of its cell body and branching fibers (dendrites/axons) | ||
| a covering of interconnected neural cells that form a thin surface layer on the cerebral hemispheres. | ||
| the body's speedy, electrochemical information network. | ||
| enables learning and memory, triggers muscle contraction (not enought leads to Alzheimer's disease) | ||
| enables voluntary control of skeletal muscles | ||
| recieves messages and conducts impulses towards the cell body. | ||
| chemical messengers that are produced in one tissue and effect another. | ||
| chemical messengers that traverse the synamptic gaps between neurons, which may or may not generate an impulse. | ||
| nerual cables containing many axons. Connects the Central Nervous System with the muscles, glands and sense organs. | ||
| controls the muscles and glands of our internal organs. | ||
| passes messages to other neurons, muscles, or glands. | ||
| automatic response to stimuli (composed of 1 sensory neuron, 1 motor neruon, and 1 interneuron to communicate through) | ||
| a set of glands that secretes hormones into the bloodstream | ||
| calms you down | ||
| arouses you. | ||
| 'morphine within'; opiate-like neurotransmitters linked to pain control and pleasure. | ||
| the gap that separates the axon terminal of one neuron from the recieving neuron. | ||
| the level of stimulation required to trigger a neural impulse | ||
| regulates growth and controls other endocrine glands, under the influence of the hypothalamus. | ||
| the branch of psychology concerned with the links between biology and behavior | ||
| where the spinal cord enters the skull and swells; responsible for automatic survival functions. | ||
| impairment of language, usually caused by damage to either Broca's or Wernicke's area. | ||
| shows brain activity by showing each area of the brain's consumption of glucose. | ||
| (sides of the head - above the ears) - includes auditory areas, each of which recieves information from the opposite ear. | ||
| cells in the nervous system that protect, nourish, and support neurons. | ||
| (located in the left frontal lobe) - controls language expression | ||
| a recording of the waves of electrical activity that sweep across the brain's surface. | ||
| a condition where the two hemispheres of the brain are isolated, by cutting connecting fibers (mainly those in the corpus callosum) between them. | ||
| the brains ability to modify itself after certain types of damage (especially in children) | ||
| long band of neural fibers connecting the two brain hemispheres and carrying messages between them. | ||
| the base of the brainstem that controls heartbeat and breathing | ||
| a pair of endocrine glands that secretes enephrine and nephrine whcih arouse the body in times of stress | ||
| brain and spinal cord. | ||
| a layer of fatty tissue that insulates the axons of neurons and helps speed their impulses | ||
| links the Central Nervous System with the body's sense receptor, muscles and glands. | ||
| interconnected neural cells. | ||
| a breif electrical charge that travels down the axon, fired when it recieves an impulse from a sense receptor. | ||
| an area at the front of the paretial lobes that registers and processes body touch and movement sensations. | ||
| (back of your head) - includes visual areas, which recieve visual information from the opposite visual feild. | ||
| a finger-shaped network of neurons that extends from the spinal cords right up the thalamus | ||
| (behind the forehead) - involved in speaking, muscle movement, making plans and judgment. | ||
| (located in the left temporal lobe) - controls language reception | ||
| a neural structure in the limbic system, right beneath the thalamus that directs maintnence activities (eating, drinking, body temp. ect) | ||
| neural clusters in the limbic system that influence agression and fear. | ||
| a donut-shaped system at the border of the brainstem that is associated with emotions and drives (includes hypothalamus, amygdala, and hippocampus) | ||
| the 'little brain' - processes sensory input and coordinates movement output and balance | ||
| tissue destruction | ||
| allows us to see structures within the brain | ||
| reveals the brain's functioning as well as its structure. | ||
| carry outgoing information from the central nervous system to the muscles and glands. | ||
| Central Nervous System Neurons that communicate/interfere with sensory inputs and motor outputs | ||
| areas of the cerebral cortext that are involved in higher mental functions like speaking, learning, remembering, and thinking | ||
| sends information from the body's tissues and sensory organs to the Central Nervous System |
