| Question | Answer |
|---|---|
| The central nervous system (CNS) consist of? | brain and spinal cord |
| In the PNS, what is in the ganglia? | neuron cell bodies |
| In the PNS, what connects to the spinal cord? | spinal nerves |
| In the PNS, what connects to the brain? | cranial nerves |
| In the CNS, the center and tracts that link the BRAIN with the rest of the body are the: | sensory and motor pathways |
| The spinal cord is a part of the: | Central Nervous System |
| The identifiable areas of the spinal cord that are based on the regions the serve include: | CERVICAL, THORACIC, LUMBAR, SACRAL |
| The cervical enlargement of the spinal cord supplies nerves to the: | shoulder girdle and arms |
| If cerebrospinal fluid was withdrawn during a spinal tap, a needle would be inserted into the: | subarachnoid space |
| The white matter of the spinal cord contains: | Large amount of myelinated and unmyelinated axons |
| The area of the spinal cord that surrounds the central canal and is dominated by the cell bodies of neurons and glial cells is the: | white matter |
| The posterior gray horns of the spinal cord contain: | somatic and visceral sensory nuclei |
| The delicate connective tissue fibers that surround individual axons of the spinal nerves comprise a layer called the: | endoneurium |
| The branches of the cervical plexus innervate the muscles of the: | neck and extend into the thoracic cavity to control the diaphram |
| The brachial plexus innervates the: | shoulder girdle and arm |
| Divergence is the "neural circuit" that permits: | the broad distribution of a specific input |
| When sensory information is relayed from one part of the brain to another the pattern is called: | serial processing |
| The final step involved in a neural reflex is: | a response by the EFFECTOR |
| The goals of information processing during a neural reflex are the selection of: | an appropiate motor response and the activation of specific motor neurons |
| In the REFLEX ARC, information processing is performed by the: | motor neuron that controls peripheral effectors |
| The basic motor patterns of innate reflexes are: | genetically programmed |
| A professional skier making a rapid, automatic adjustment in body position while racing is an example of: | acquired reflex |
| When a sensory neuron synapses directly on a motor neuron, which itself serves as the processing center, the reflex is called: | monosynaptic reflex |
| The sensory receptors in the stretch reflex are: | muscle spindles |
| When one set of motor neurons is stimulated, those controlling antagonistic muscles are inhibited. This is an example of: | contralateral reflex |
| What basic characteristics do all polysynaptic reflexes share? | reciprocal innervation |
| As descending inhibitory synapses develop | the Babinski response disappears |
| The highest level of motor control involves a series of interactions that occur: | in centers in the brain that can modulate or build upon a reflexive motor pattern |
| In the PNS, neuron cells are located in: | ganglia |
| The terminal portion of the spinal cord is called: | conus medullaris |
| The supportive fibrous strand of the PIA MATER is the: | filum terminae |
| The cell bodies of neurons in the gray matter of the spinal cord form groups called: | nuclei |
| The white matter of the spinal cord is divided into regions called: | columns |
| The outermost layer of a spinal cord | epineurium |
| The branch of eachspinal nerve that provides sensory and motor innervation to the skin and muscles of the back | dorsal ramus |
| The area where each spinal nerve monitors a specific region of the body surface is known as | dermatome |
| When 2 neuronal pool synapses on the same motor neurons, the process is called | convergence |
| Automatic motor responses, triggered by specific stimuli | neural reflexes |
| A specialized cell that monitors conditions in the body or the external environment | receptor |
| Connections that form between neurons during development produce: | innate reflexes |
| Complex, learned motor patterns | acquired reflexes |
| Reflexes processed in the brain | cranial reflexes |
| Reflexes that control activities of the muscular system | somatic reflexes |
| A motor response that occurs on the side opposite the stimulus | crossed extensor reflex |
| The withdrawal reflex affecting the muscles of the limb | flexor reflex |
| Elevated facilitation leading to an enhancement of spinal reflexes | reinforcement |
| Stroking an infant's foot on the side of the sole produces a fanning of the toes | Babinski reflex |
| axons | nerve bundles |
| dorsal roots | sensory information to spinal cord |
| ventral roots | contains axons of motor neurons |
| spinal meninges | specialized membranes |
| white matter | ascending,descending tracts |
| epineurium | outermost layer of spinal cords |
| cervical plexus | spinal nerves C1-C5 |
| brachial plexus | spinal nerves C5-T1 |
| reverberation | positive feedback |
| neural "wiring" | reflex arc |
| peripheral effector | muscle or gland cells |
| somatic reflexes | controls the activites of the muscular system |
| stretch reflex | monosynaptic reflex |
| tendon reflex | golgi tendon organ |
| crossed extensor reflex | contralateral response |
| same-side reflex | ipsilateral response |
| descending pathways | provides facilitation, inhibition |
