This information implies that the photoreceptor cells are continuously sending visual signals to the brain. The constant release of neurotransmitters indicates that the photoreceptor cells are actively responding to light stimuli. This activity is crucial for maintaining normal vision and processing visual information.

Why do earthworms have photoreceptor cells?
Earthworms have photoreceptor cells to detect light and darkness. These cells help them navigate their environment and determine whether it is day or night. This information is crucial for their survival, as it helps them find food, avoid predators, and regulate their behavior and activity patterns.
What mimic or enhance the effects of a neurotransmitter on the receptor sites of the next cell increasing or decreasing the activity of that cell?
Agonists mimic or enhance the effects of neurotransmitters by binding to the receptor sites of the next cell and increasing the activity of that cell. Antagonists, on the other hand, block or inhibit the effects of neurotransmitters, resulting in decreased activity of the cell.
Can neurotransmitter be exogenous?
Yes, exogenous neurotransmitters are chemicals that are taken from outside the body and can affect neurotransmitter activity in the brain. These can include medications like antidepressants and stimulants that alter the levels of neurotransmitters like serotonin, dopamine, and norepinephrine.
What neurotransmitter functions as a common inhibitory neurotransmitter in the brain?
Gamma-aminobutyric acid (GABA) is the main inhibitory neurotransmitter in the brain. It works to reduce the activity of neurons, thus promoting relaxation and reducing anxiety. Dysregulation of GABA signaling has been linked to various neurological conditions, such as epilepsy and anxiety disorders.
The neurotransmitters acetylcholine performs what two functions?
Acetylcholine functions as both a neurotransmitter in the nervous system, where it is involved in transmitting signals between nerve cells, and as a neuromodulator that influences the activity of other neurotransmitter systems. It plays a critical role in muscle contraction and movement, as well as in memory, learning, and attention.

When the binding of a neurotransmitter to a dendrite will result in?
The binding of a neurotransmitter to a dendrite will cause one these three things to happen:excitement (stimulation)inhibition (stop activity)modulation (change activity by slowing it or increasing it)It all depends on the neurotransmitter. Neurotransmitter are means by which neurons communicate with one another. There are more than 30 compounds known to be neurotransmitters, and dozens of others are thought to be so.
What adrenergic neurotransmitter receptor plays a role in heart activity?
beta neuron
Chemical messenger released from the neuron that are involved in all types of behavior activity?
neurotransmitter

What neurotransmitter might the parietal lobe use and why?
The parietal lobe primarily uses neurotransmitters such as glutamate and GABA. Glutamate is excitatory and involved in processing sensory information, while GABA is inhibitory and helps regulate the activity of glutamate to maintain a balance in neural signaling within the parietal lobe.
What Changes activity of neurotransmitter?
Psychotropics (stimulants, depressants, antidepressants, anxiolytics, sedative/hypnotics, antipsychotics, dissociatives, etc.)
What shape indicates manual activity in a flowchart?
oval

How does phenylethylamine elivate moods?
Phenylethylamine is a naturally occurring compound that acts as a neurotransmitter in the brain. It can elevate mood by increasing the release of dopamine and serotonin, which are chemicals associated with feelings of pleasure and well-being. This increase in neurotransmitter activity can result in improved mood and feelings of happiness.
