What is the most common of the receptive dysphasia?
The most common type of receptive dysphasia is Wernicke's aphasia. This is characterized by fluent but nonsensical speech, poor comprehension, and difficulty with word retrieval and naming objects. It is typically caused by damage to the left temporal lobe of the brain.
Conduction along a myelinated axon is called?
It is called saltatory conduction. This describes the "jumping" of an action potential from node to node on a myelinated axon.
Why is saltatory conduction relatively rapid compared to continuous conduction?
Saltatory conduction is faster than continuous conduction because in saltatory conduction, the electrical signal jumps between nodes of Ranvier on the myelinated axon, skipping the sections covered by myelin. This allows the signal to travel faster as it doesn't have to travel the entire length of the axon.
COnduction speed of a nerve fiber would be the fastest in a?
Myelinated nerve fiber with a large diameter would have the fastest conduction speed. The myelin sheath allows for saltatory conduction, where the action potential jumps from one node of Ranvier to the next, speeding up conduction. A large diameter also reduces resistance to current flow, further increasing conduction speed.
What is dromotropic effect?
Dromotropic effect is the effect on conduction of current. It could be positive or negative depending on the final outcome. A negative dromotropic effect would mean decrease in conduction activity of current while positive would mean increase in conduction activity of current.
What is associative dysphasia also called?
Conduction dysphasia
What is conduction dysphasia also called?
Associative dysphasia
Is conduction dysphasia common?
Conduction dysphasia is a relatively uncommon disease (representing only 10% of the cases)
What causes transcortical dysphasia?
Transcortical dysphasia is caused by damage to the language-dominant brain that separates all or parts of the central region from the rest of the brain
How is dysphasia cured?
Dysphasia can be prevented by avoiding the causes of brain injury and stroke, such as high blood pressure
What is another word for Anomic dysphasia?
Anomic dysphasia is also referred to as amnesic dysphasia
What is the most common form ofexpressive dysphasia?
Broca's dysphasia is the most common type of expressive dysphasia
What is another name for motor dysphasia?
Expressive dysphasia
What is another word for amnesic dysphasia?
Anomic dysphasia
What is Sensory dysphasia also called?
Receptive dysphasia
Do strokes cause dysphasia?
Stroke is the most common cause for dysphasia
What causes associative dysphasia?
Damage to the upper temporal lobe, lower parietal, or connection between the Wernicke's and Broca's areas
