Final Exam Flashcards
A complex protein that is manufactured by cells
Enzyme
A basic cell that makes up the nervous system, it receives and sends messages
Neuron
What lobe of the brain is responsible for touch, taste, temperature and body position
Perietal Lobe
24 hour bodily rhythm
Circadian rhythm
Any significant loss of sleep, causing problems in concentration or irritability
Sleep Deprivation
Theory that animals evolved sleep patterns to avoid predators by sleeping when predators are most active
Adaptive Theory
Condition resulting from damage to Broca’s area (usually in left frontal lobe), causing the affected person to be unable to speak fluently, to mispronounce words, and to speak haltingly
Broca’s Aphasia
What are the 3 types of neurons?
- Sensory Neuron
- Motor Neuron
- Interneuron
The release of the neural impulse consisting of a reversal of the electrical charge within the axon
Axon Potential
What does the Peripheral Nervous System consist of?
Autonomic and Somatic
Fatty substances produced by certain glial cells that coat the axons of neurons to insulate, protect, and speed up the neural impulse
Myelin
Bundles of axons in the body that travel together through the body
Nerves
Brain-imaging method using radio waves and magnetic fields of the body to produce detailed images of the brain
Magnetic Resonance Imaging (MRI)
Study of neural structures, behavior, and learning
Neuroscience
Process by which neurotransmitters are taken back into the synaptic vesicles
Reuptake
What lobe of the brain deals with hearing and meaningful speech?
Temporal Lobe
Charged particles
Ions
The awareness of everything going on inside and outside of you
Consciousness
A neuron that carries messages from the senses to the CNS.
Sensory Neurons
The state of the neuron when not firing a neural impulse
Resting potential
Milder electrical current used to stimulate neural activity in the brain
Electrical stimulation of the brain
Referring to the fact that a neuron either fires completely or does not fire at all
All-or-none
Chemical found in the synaptic vesicles which, when released, has an effect on the next cell
Neurotransmitters
Holes in the surface of the dendrites or certain cells of the muscles and glands, which are shaped to fit only certain neurotransmitters
Receptor Sites
What does the Central Nervous System consist of?
The brain and spinal cord
What controls involuntary muscles?
Autonomic
What 4 things do Glial Cells do?
- Provide support for the neurons to grow on and around
- Deliver nutrients to neurons
- Produce myelin to coat axons
- Clean up waste products and dead neurons
Tunnel through which damaged nerve fibers can repair themselves
Neurilemma
What is the charge on an inside neuron?
Negative
A branch-like structure that receives messages from other neurons
Dendrites
Bundle of neurons that carries information from the CNS to the muscles
Spinal Cord
Carries information to and from all parts of the body
The Nervous System
What lobe of the brain deals with fluent speech?
Frontal Lobe
Tiny section of the brain that influences glandular system
Hypothalamus
Brain-imaging method using computer controlled x-rays of the brain
Computed Tomography (CT)
Brief sidesteps into sleep lasting only a few seconds
Microsleeps
Internal clock that tells you when to wake up and fall asleep
Suprachiasmatic Nucleus
This is the cell body. It maintains the life of the cell.
Soma
Rounded areas on the end of axon terminals
Synaptic Vessicles
A neuron that carries messages from the CNS to the muscles
Motor Neuron
Grey fatty cells
Glial cells
What controls voluntary muscles?
Somatic
What is the charge on an outside neuron?
Positive
Thick band of neurons that connects the right and left cerebral hemispheres
Corpus Collosum
The wrinkled outermost covering of the brain
Cortex
Machine designed to record the brain wave patterns produced by electrical activity of the surface of the brain
Electroencephalograph (EEG)
Microscopic fluid-filled space between the rounded areas on the end of the axon terminals of one cell and the dendrites or surface of the next cell
Synapse/ Synaptic gap
Electrical current used to destroy brain cells
Deep Lesioning
A neuron found in the center of the spinal cord that receives messages from the senses and sends it to the muscles
Interneuron
Long tubular structure that sends messages to other cells
Axon
