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. |
