What are Structural classification neurons?
Biopolar multipolar unipolar
What plays a critical role as a functional junction between neurons?
SYNAPSE
Functional difference between a motor and a relay neuron?
Motor neurons are the efferent neuron which carry impulses from CNS to muscles while relay neurons also known as Inter neurons connect both afferent and efferent neurons.
The function classification of a type of joint that is freely movable?
diarthrosis - all synovial joints are freely moveable
When your hit in the head do you damage the neurons in your brain or the axons?
When you are hit in the head, both neurons and axons can sustain damage. Neurons are the specialized cells responsible for transmitting electrical signals in the brain, while axons are long, slender projections that extend from neurons and transmit those signals to other neurons or tissues. Impact to the head can cause direct damage to neurons and axons, leading to functional impairment or cell death.
Which of the following is NOT a functional classification of neurons?
Extraneurons
What is the functional component of the nervous system?
Neurons.
Are neurons in the CNS organized into functional groups?
Yes.
What are Structural classification neurons?
Biopolar multipolar unipolar
What plays a critical role as a functional junction between neurons?
SYNAPSE
Is the nerve the functional unit of the nervous system?
No. The functional unit of the nervous system is the neuron. Neurons group together to form nerves.
The functional classification of salivary glands is?
Merocrine glands
What is the functional classification for voluntary nerves?
somatic motor
Functional difference between a motor and a relay neuron?
Motor neurons are the efferent neuron which carry impulses from CNS to muscles while relay neurons also known as Inter neurons connect both afferent and efferent neurons.
What functional advantages a neuron with several have over a neuron with only one dendrite?
These are also called multipolar neurons and they allow for the integration of a great deal of information from other neurons.
Define irregular involuntary contraction of a muscle usually resulting from functional disorder of motor neurons?
Myoclonus
What structural classification describes this neuron?
Usually by size and the type of neurotransmistter it produces. Electrophysiologists also classify neurons by their firing ratesThis is an addition to the above-mentioned answer. To be more specific, we can classify neurons based on their structural or functional properties.1) Structural classification :based on polarity = unipolar + pseudounipolar + bipolar, + multipolar (Golgi 1, Golgi 2)based on their unique features (distinct shapes and locations) = basket cells + betz cells + medium spiny neurons + purkinje cells + pyramidal cells + Renshaw cells + granule cells + anterior horn cells2) Functional classification :based on directions = afferent + efferent + interneuronsbased on their actions on other neurons = excitatory (they increase firing rate) + inhibitory(they decrease firing rate) + modulatory (doesn't really related to firing rate, but they cause long-lasting effects)based on their discharging patterns = tonic or regular spiking + phasic or bursting + fast spikingbased on neurotransmitters they produced = cholinergic + GABAergic + glutamatergic + dopaminergic + serotonergic
