Speech Disorders
Severe language impairment that affects all aspects of communication, including speaking, understanding, reading, and writing.
What is global aphasia?
The number of cranial nerves and the number of cranial nerves that are motor nerves.
What are 12 cranial nerves and 4 motor nerves?
The basic structural unit of the nervous system, responsible for transmitting electrical signals
The four lobes of the brain and what is considered to be the "fifth" lobe
What are the frontal, parietal, occipital, and temporal lobes and the insula?
Step 1
What is the reception of a stimulus by a sensory receptor, which could be located in the skin, muscles, or other tissues?
Characterized by fluent but nonsensical speech; difficulty understanding language and may produce sentences with incorrect or invented words
What is Wernicke’s aphasia?
The part of the brainstem to which cranial nerve VII is attached.
What is the midpons part of the brainstem?
These neurons carry information from the sensory organs to the central nervous system.
What are afferent neurons?
The lobe in which Broca's area is located
What is the left frontal lobe?
Step 2
What is the sensory neuron/afferent neuron carries the signal from the receptor to the central nervous system. The axon of the sensory neuron transmits the nerve impulse toward the spinal cord?
Also known as non-fluent aphasia; characterized by difficulty producing speech.
What is Broca’s aphasia?
This cranial nerve's function is taste and swallowing.
What is the CN IX or glossopharyngeal nerve?
These neurons are responsible for transmitting signals from the central nervous system to muscles and glands, enabling motor control.
What are efferent neurons?
The location of the primary somatosensory cortex and its function.
What is the anterior part of the parietal lobe and what is detecting touch, pain, and temperature?
Step 3
What is in the spinal cord, the sensory neuron communicates with an interneuron or directly with a motor neuron?
Motor speech disorder resulting in weakness, paralysis, or incoordination of the muscle involved in speech production.
What is dysarthria?
The cranial nerves are specifically involved in speaking, swallowing, and hearing.
What are cranial nerves V, VII, VIII, IX, X, XI, and XII?
The term for the neural pathway that controls a reflex action, often bypassing the brain for a rapid response.
What is a reflex arc?
The function of the temporal lobe
What is understanding language, retrieving memories, and auditory processing?
Step 4
What is if the integrated signal indicates a need for a response, a motor neuron/efferent neuron is activated. The motor neuron carries the signal away from the spinal cord toward the effector organ, usually a muscle or gland?
Motor speech disorder characterized by the inability to plan and coordinate the movements necessary for accurate speech production.
What is apraxia of speech?
List the cranial nerves.
What are the
I: Ofalctory
II: Optic
III: Oculomotor
IV: Trochlear
V: Trigminal
VI: Abducens
VII: Facial
VIII: Vestibucochlear
IX: Glossopharyngeal
X: Vagus
XI: Accesory
XII: Hypoglossal
The neuron coating that helps speed up the transmission of signals along the axon.
What is the myelin sheath?
The name of the collection of structures that serve motivation, emotions, memory, and adaptive functions
What is the limbic system?
Step 5 and Step 6
What is the motor neuron's signal reaches the effector organ, which carries out the response to the original stimulus. Then it results in a reflex action that occurs without conscious thought?
