Question | Answer |
autonomic nervous system | collection of nerves, ganglia, and plexuses through which visceral organs,heart, blood vessels, glands, and smooth muscles receive their innervation |
arachnoid | weblike middle membrane of meninges |
associative neuron (interneuron) | carries messages from sensory neuron to motor neuron |
axon | nerve cell structure which carries impulses away form cell body to dendrites |
blood-brain barrier | substance cannot penetrate the brain tissue |
brain stem | portion of brainother than cerebral hemispheres and cerebellum |
central nervous system | consists of the structures of the brain and spinal cord |
cerebrospinal fluid | a substance that forms within the four brain ventricles from the blood vessels of the choroid plexus; this serves as a shock absorber protecting the brain and spinal cord |
cerebrum | the largest part of the brain |
cerebellum | structure of the brain behind the pons and below the the cerebrum |
choroid plexus | the network of blood vessels of the pia mater |
cranial nerves, | twelve pairs of nerves that begin in the brain and transmit messages to various parts of the face and head to stimulate various functions |
dendrite, | nerve cekk process that carries nervous impulses toward the cell body |
diencephalon, | posterior part of the brain; contains the thalamus, hypothalamus, and pituitary gland |
dura mater, | fibrous membrane forming outermost covering of brain and spinal cord |
frontal lobe, | in cerebral cortex, controls the motor function |
hypothalamus, | part of the diencephalon, lies below the thalamus |
medulla oblongata, | part of the brainstem, contains the nuclei for vital functions |
meninges, | any of three linings enclosing the brain and spinal cord |
motor neuron (efferent), | carries messages from brain and spinal cord to muscls and glands |
myelin sheath (neurilemma), | layers of cell membrane that wrap nerve fibers, providing electrical insulation and increasing the velocity of impulse transmission |
neuron, | nerve cell; including its processes |
occipital lobe, | part of the cerebrum that houses the foramen magnum |
parasympathetic nervous system, | divison of the autonomic nervous system inhibits or opposes the effects of the sympathetic nervous system |
parietal lobe, | division of the cerebrum that lies beneath the parietal bone |
peripheral nervous system, | made up of 12 pairs of cranial nerves and 31 pairs fo spinal nerves |
pia mater, | innermost vascular covering of brain; and spinal cord |
pons, | part of the brainstem |
receptors, | sensory nerves that receives a stimulus and transmits it to the CNS |
reflex, | involuntary action; automatic response |
spinal nerves, | thiry one pairs, originate in the spinal cord |
stimulus, | any change in environment |
sensory neuron (afferent), | a nerve that carries nerve implses from the periphery to the central nervous system |
spinal cord, | part of the central nervous system within the spinal column; begins at foramen magnum of occipital bone and continues to the second lumbar vertebra |
sulci, | fissure of grooves separtaing cerebral convolutions |
sympathetic nervous system, | division of autonomic nervous system |
synapse, | space between adjacent neurons through which an impulse is transmitted |
temporal lobe, | part of the cerebral hemisphere associated with the perception and interpretation of sound |
thalamus, | part of the diencephalon, relayys sensory stimuli to the cerebral cortex |
Alzheimer's Disease, | progressive disease with degeneration of the nerve endings in the cortex of the brain |
Bell’s Palsy, | disorder that affects the facial nerve |
cerebral palsy, | a disturbance in voluntary muscke action due to brain damage |
dementia, | loss in at least two areas of complex behavior |
Encephalitis, | inflammation of the brain |
Epilepsy, | seizure disorder |
Meningitis, | inflammation of the lining of the brain and spinal cord |
Hemiplegia, | (blankparlaysis of one side of the body |
Hydrocephalus, | increase in the volume of cerebral spinal fluid within the cerebral ventricles, may occur in fetal development |
lumbar puncture, | removal of cerebrospinal fluid for diagnostic purposes by insertion of a needle between the third and fourth lumbar vertebrae |
multiple sclerosis, | chronic inflammatory disease in which the immune cells attack the myelin sheath of a nerve |
neuritis, | inflammation of a nerve |
Parkinson’s disease, | (blank) |
