| Question | Answer |
|---|---|
| what are neurons | nerve cells |
| communication, information processing, control are all functions of? | neurons |
| phagocytosis, provide supportive framework for tissue, regulation composition of interstitual fluid, are all functions of ? | neuroglia |
| what are supporting cells | glial cells |
| what are glial cells? | neuroglia |
| what are the two neural tissue cell types | neurons and neuroglia |
| what are the two anatomical division of nervous systems? | CNS and PNS |
| The spinal cord and the brain are located in the? | Central nervous system |
| All neural tissue outside the CNS are located in the | Peripheral nervous system |
| integrate, process, and coordinate sensory data and motor commands are all functions of | Central nervous system |
| Deliver sensory info to the CNS, carry motor commands to peripheray, cranial vs spinal nerves are all functions of | Peripheral nervous systems |
| What are the two function division of PNS | Afferent division and Efferent division |
| what brings information to the CNS | Afferent division |
| What takes information from the CNS | Efferent division |
| Where does the information come from | Receptors |
| what are the sensory structure that detects changes in the environment | Receptors |
| Receptors | respond to stimuli |
| What responds by doing something | Effectors |
| What are the divisions of Efferent | Somatic Nervous system and Autonomic Nervous system |
| What are the four structual classification on Neurons? | Anaxonic neuron, Bipolar neuron, Unipolar neuron, and Multipolar neuron. |
| The Anaxonic neuron consist of | Brain and sense organs |
| The Bipolar neuron is | Only in sense organs (rare) |
| The Unipolar neuron consist of | most sensory neurons |
| The Multipolar neuron consist of | All motor neurons that control skeletal muscles |
| Anaxonic neurons | have more than two processes, but axons cannot be distinguished from dendrites. |
| Bipolar neurons | have two processes separated by the cell body. |
| Unipolar neurons | have a single elongate process, with the cell body situated off t the side. |
| Multipoloar neurons | have more than two processes, there is a single axon and multiple dendrites. |
| What are the 4 functional classifications of Neurons | Sensory neurons, Sensory receptors, Motor Neurons, and interneurons. |
| Sensory Neurons are also known as | Afferent Neurons |
| What delivers info to CNS from sensory receptors? | Sensory Neurons |
| collection of neural cell bodies in the PNS | Sensory ganglia |
| Two types of sensory Neurons | Somatic sensory Neuron and Visceral sensory neuron |
| what monitors the outside | somatic sensory neurons |
| What monitors internal | visceral sensory neurons |
| Process of specialized sensory neurons or cells monitored by sensory neurons | Sensory Receptors |
| Three types of sensory receptors | Interoreceptors, Exterorecepters, and Proprioreceptors. |
| What monitors position and movement of skeletal muscles and joints | Proprioreceptors |
| Exteroreceptors | monitor external environment |
| Interoreceptors | monitor systems |
| Motor Neurons are also called | Efferent Neurons |
| Motor Neurons | tatkes information from the CNS to PNS |
| What are the two types of Motor neurons | Somatic Motor Neurons and Visceral Motor Neurons |
| What innervate skeletal muscles | Somatic motor neuron |
| Somatic motor neuron | Axon extends to the muscle |
| cell body in the CNS | Somatic Motor Neuron |
| Somatic Motor Neuron | Consciously controlled |
| Visceral Motor Neuron | Innervate all peripheral effectors except skeletal muscles |
| Visceral motor neuron | signal must be relayed across a synapse |
| visceral motor neuronsin central nervous system send out axons to second set of visceral motor neurons in | peripheral autonomic ganglia |
| visceral motor neuron consist of two fibers | preganglionic fibers and postganglionic fibers |
| Interneurons also called | assciation neurons |
| interneurons | outnumber all other neurons combined |
| most interneurons are located in the | brain and spinal cord, some ar ein the autonomic ganglia |
| distribution of sensory information and coordinate motor ativity are all functions of | Interneurons |
| neuroglia are found in | central nervous system and peripheral nervous system |
| central nervous system contains | Ependymalcells, Astrocytes, Oligodendorcytes, and Microglia |
| Peripheral nervous system contains | Satellite cells and Schwann cells |
| Ependymal cells | line ventricles (brain) and central canal (spinal cord). |
| What assist in producing, circulatin, and monitoring cerebrospinal fluid | Ependymal cells |
| Astrocytes | Maintain blood-brain barier; |
| what provides structural support; regulate ion, nutrient, and dissolved gas concetrations; absorb and recycle neurotransmitters; form scar tissue after injury | Astrocytes |
| Oligodendrocytes | Myelinate CNS axons. |
| what provides structural framework | Oligodendrocytes |
| Microglia | Removes cell debris, waste, and pathogens by phagocytosis |
| Satellite cells | surround neuron cell bodies in ganglia |
| what regulates oxygen,carbon dioxide, nutrient, and neurotransmitter levels around neurons in ganglia | Satellite cells |
| Schwann cells | surround all axons in PNS; responsible for myelination of peripheral axons; |
| What particiaptes in repair process after injury | Schwann cells |
| Ependymal cells | A fluid filled central passageway extends along the longitudinal axis of the spinal cord and brain. |
