This NT plays a role in:
- arousal/sleep
- cognition
- memory
- contraction of skeletal muscles
- learning
ACH
Too much of this NT can result in:
- dry mouth
- HA
- altered sense of taste
- n/v
- nightmares
- depression
D. ACH
Too little ACH can be associated with:
A. Dementia/alzhimer's
This NT inhibits violent tendencies, regulates temperature, sleep cycle and pain perception, and also plays a role in eating behavior and anxiety:
C. Serotonin
Too much serotonin can lead to:
C.
Too little of this NT can lead to insomnia, increased suicidal ideation, and OCD:
C. Serotonin
T or F: Norepinephrine is also a hormone
True: it is secreted by a gland to be distributed to mellow out smooth muscles
Capsaicin blocks this NT
Substance P - a peptide that transmits pain signals
What is the function of endorphins?
Inhibits the transmission of ain signals, produce euphoria
This NT is considered the "learning neurotransmitter"
It also plays a role in mood and addictions:
B. Dopamine
Too much dopamine can cause:
C.
Severe deficit of this NT can cause some depression, muscular rigidity, Parkinson's symptoms:
D.
This NT is an inhibitory NT, and it regulates anxiety and severe deficits of it can cause seizures.
Gaba: an inhibitory NT
This NT is an amino acid. Too much of it an cause brain diseases (alzheimer's, ALS, seizures).
It plays a role in memory, learning.
Glutamate: excites neurons and causes them to fire
Too little of this NT an cause symptoms of schizophrenia and other thought disorders.
(Hint: it has the structure of an amino acid)
Gaba
This cognitive dx is a language impairment; with difficulty of production and comprehension of speech.
Injury to the frontal and temporal lobes (left commonly)
C. aphasia
This dx is disturbances in organizing voluntary movements: poor ADLs
D. apraxia
This dx is the disorganization of perception and recognition; seen in injury to the parietal lobe
A. agnosia
this dx is the poverty of speech.
seen in dementia, schizophrenia, and injury to left hemisphere of the brain.
D. alogia

question only answered after excessive details are given
What is tangential speech?
wanders from topic to topic, never returning to original topic
