What is the CENTRAL NERVOUS SYSTEM?
The portion of the nervous system consisting of the brain and spinal cord. Responsible of receiving, processing, interpreting and storing of sensory information.
What is the SPINAL CORD?
A collection of neurons and supportive tissue running from the base of the brain down the center of the back, protected by a column of bones, the spinal column.
What is the PERIPHERAL NERVOUS SYSTEM?
All portions of the nervous system outside the brain and spinal cord; in includes sensory and motor nerves.
What is the SOMATIC NERVOUS SYSTEM?
The subdivision of the peripheral nervous system that connects to sensory receptors and to skeletal muscles; sometimes called the SKELETAL NERVOUS SYSTEM.
What are the two parts of the Periperipheral Nervous System?
1. The Somatic Nervous System and 2. the Autonomic Nervous System.
What is the AUTONOMIC NERVOUS SYSTEM?
The subdivision of the peripheral nervous system that regulates the glands, blood vessels, internal organs.
What is the SYMPATHETIC NERVOUS SYSTEM?
The subdivision of the autonomic nervous system that mobilizes bodily resources and increases the output of energy during emotion and stress.
What is the PARASYMPATHETIC NERVOUS SYSTEM?
The subdivision of the autonomic nervous systems that operations during relaxed states and that conserves energy.
What is a NEURON?
A cell that conducts electrochemical signals; the basic unit of the nervous system; also called a nerve cell.
What is the CELL STRUCTURE OF THE NERUORN?
Dendrites, Cell Body, Axon. Remember by Dogs Can Bark Always, DCBA
What is a DENDRITE?
A neuron's branches that receive information from other neurons and transmit it toward the cell body.
What is the CELL BODY?
The part of the neuron that keeps it alive and determines whether it will fire.
What is an AXON?
A neuron's extending fiber that conducts impulses away from the cell body and transmits them to other neurons.
What is the MYELIN SHEATH?
A fatty insulation that may surround the axon of a neuron. Remember as insulation on a wire.
What is the STRUCTURE OF A NEURON?
Incoming neural impulses are received by the Dendrites of a neuron and are transmitted to the cell body. Outgoing signals pass along the axon to terminal branches.
What is a NERVE?
A bundle of nerve fibers (axons and sometimes Dendrites) in the peripheral nervous system.
NEUROGENISIS is?
The production of new neurons from immature stem cells.
What is a STEM CELL?
Immature cells that renew themselves and have the potential to develop into mature cells; give encouraging environments, stem cells from early embryos can develop into any cell type.
What is a SYNAPSE?
The site where transmission of a nerve impulse from one nerve cell to another occurs; it includes the axon terminal, the synaptic cleft, and receptor sites in the membrane of the receiving cell.
What are ENFORPHINS?
They are chemical substances that create the WOW! Are similar in structure and action to opiates; they are involved in pain reduction, pleasure and memory.
What are HORMONES?
The Long Distance Messengers. Hormones are chemical substances, secreted by organs called glands, that affect the functioning of other organs.
What are the ENDOCRINE GLANDS?
Internal organs that produce hormones and release them into the bloodstream.
What is MELATONIN?
A hormone, secreted the the PINEAL GLAND, that is involved in the regulation of daily biological rhythms.
What are the ADRENAL HORMONES?
Hormones that are produced by the adrenal glands and that are involved in emotion and stress.
What are SEX HORMONES?
Hormones that regulate the development and functioning of reproductive organs and that stimulate the development of male and female sexual characteristics; they include androgens, estrogen, and progesterone.
What is an ELECTROENCEPHALOGRAM - EEG?
A recording of neural activity detected by electrodes.
What is TRANCRANIAL MAGNETIC STIMULATION - TMS?
A method method of stimulating brain cells, using a powerful magnetic field producted by a wire coil placed on a person's head; it can be used by researches to temporarily inactive neural circuits and is also being used therapeutically.
What is a PET scan?
Positron-emission tomography, is a method for analyzing biochemical activity in the brain, using injections of glucose-like substance containing a radioactive element.
What is an MRI?
Magnetic Resonance Imaging, a method for studying body and brain tissue, using magnetic fields and special radio receivers.
Waht is the BRAIN STEM?
The part of the brain at the top of the spinal cord, consisting of the medulla adn the pons.
What is the PONS?
A structure in the brain stem involved in, among other things, sleeping, waking and dreaming.
What is the MEDULLA?
A structure in the brain stem responsible for certain automatic functions including breathing adn heart rate.
What is the RESTICULAR ACTIVATING SYSTEM - RAS?
A defense network of neurons found in the core of the brain stem; it arouses the cortex and screens incoming information.
What is the CEREBELLUM?
A dense network of neurons found in the core of the brain stem; it arouses the cortex and screens incoming information.
What is the THALMUS?
Referred to as the Busy Traffic Officer of the brain; a brain structure that relays sensory messages to the cerebral cortex.
What is the HYPOTHALAMUS?
A brain structure residing under the Thalamus that is involved in emotions and drives vital to survival, such as fear, hunger, thirst and reproduction; it regulates the autonomic nervous system.
What is the PITUITARY GLAND?
A small endocrine gland at the base of the brain which releases many hormones and regulates other endocrine glands.
What is the LIMBRIC SYSTEM?
A group of brain areas involved in emotional reactions and motivated behavior.
What is the AMYGDALA?
A brain structure involved in the arousal and regulation of emotion and the initial emotional response to sensory information.
What is the HIPPOCAMPUS?
A brain structure involved in the storage of new information in memory.
What is the CEREBRUM?
The largest brain structure, consisting of the upper part of the brain; divided into two hemispheres, it si in charge of most sensory, motor, and cognitive processes. From the Latin for Brain.
What is the CEREBRAL HEMISPHERES?
The two halves of the cerebrum.
What is the CORPUS CALLOSUM?
The bundles of nerve fibers connecting the two cerebral hemispheres.
What is LATERALIZATION?
Specialization of the two cerebral hemispheres for particular operations.
What is the CEREBRAL CORTEX?
A collection of several thin layers of cells covering the cerebrum; it is largely responsible for higher mental functions. Cortex is Latin for Bark or Rind.
