| Question | Answer |
|---|---|
| What is sensory input? | changes are monitored inside and outside the body |
| What is integration? | the input is interpreted and decide a course of action |
| What is motor output? | it causes a response by activating organs, muscles, or glands |
| What makes up the central nervous system? | brain and spinal cord |
| What makes up the peripheral nervous system? | cranial and spinal nerves |
| What's another name for sensory input? | afferent |
| What's another name for motor output? | efferent |
| Do supporting cells regenerate in the CNS? | no, they could turn to cancer |
| What is the PNS supporting cells? | schwann cells |
| What is a nueron? | a cell that conducts impulses |
| What are dendrites? | they have a graded response which is proportional to the stimulus |
| What is threshold? | stimulus strong enough to start an action potential |
| What is an axon? | it has an action potential, all or none |
| Which type of neuron has a thick diameter, and lots of myelin? | type A |
| Which type of neuron has a middle diameter, and moderate myelin? | type B |
| Which type of neuron has a small diameter, and little or no myelin? | type C |
| Which type of neuron is used for reflexes? | type A |
| Which type of neuron is used for receiving information from organs? | type B |
| Which type of neuron is used for pain? | type C |
| Which type of neuron has the best chance at healing? | type A |
| What is neuron speed based off? | the size of the axon and amount of myelin |
| What makes a neuron fast? | the larger the diameter of the axon, and the more myelin it has |
| What is the medulla oblongata? | basic respiratory, vasomotor and cardiac center |
| What is the pons? | connection between the spinal cord, cerebellum, and higher brain centers |
| What is the cerebellum? | responsible for grace and balance |
| What is the thalmus? | sensory switching center |
| What is the hypothalmus? | controls autonomic nervous system |
| What is the limbic system? | set of nuclei that are the site of survival emotions |
| What are the primary areas of the cerebrum? | they receive basic information; acoustic, visual, auditory, gustitory, olifactor |
| What are the association areas of the erebrum? | they take basic information and put on a label |
| What is grey matter? | neurons talking to neurons |
| What is white matter? | cables |
| Which autonomic nervous system stimulates to get ready for stress? | sympathetic |
| Which autonomic nervous system is resting and digesting? | parasympathetic |
| Where does short term memory take place? | the hippocampus |
| Where does long term memory take place? | cerebral cortex |
| What is short term memory? | a neurochemical event |
| What is long term memory? | change in neuron structure |
| What are the layers of the brain? (inner to outer) | pia, arachnoid, and dura matter |
| What is hydrpcephalis? | water on the brain |
| What is ipsilateral? | stimulus and response are on the same side |
| What is monosynaptic? | one connection sensory and motor |
| what is polysynaptic? | multiple connections |
| What is contralateral? | stimulus and response are on opposite sides |
| What are the stretch reflexes? | monosynaptic, ipsilateral |
| What are the flexor reflexes? | polysynaptic, ipsilateral |
| What are the crossed extensor reflexes? | polysynaptic, contralateral |
| Which neurons repair? | schwann cells (PNS) |
