Which nervous system dominates the control of effector organs under normal everyday conditions?
The autonomic nervous system dominates the control of effector organs under normal everyday conditions. It consists of the sympathetic and parasympathetic divisions, which work together to maintain homeostasis by regulating functions such as heart rate, digestion, and respiration without conscious effort.
Cells that carry out a response to a stimulus are called?
effector
What is the name of the neuron that contacts the effector organ?
Motor neurons are able to create a response in effector organs, muscles and glands by sending signals to them.
How does effector relate to reflex arc?
An effector is a part of the body (such as a muscle or gland) that carries out the response in a reflex arc. In a reflex arc, when a stimulus is detected by a sensory receptor, a message is sent via a sensory neuron to the spinal cord, where it is processed, and then a message is sent via a motor neuron to the effector causing a response.
Which structure of a feedback system receives output from the control center?
The structure that receives output from the control center in a feedback system is typically the effector. The effector is responsible for carrying out the response dictated by the control center to maintain homeostasis or achieve the desired outcome.
What component of the ANS is characterized by ganglion located in or near effector organs?
The component of the ANS that is characterized by ganglion located in or near effector organs is called the parasympathetic nervous system. The ganglia of the parasympathetic nervous system are located close to or within the target organs they innervate, allowing for direct and localized control of bodily functions. This branch of the autonomic nervous system is responsible for promoting rest, digestion, and relaxation.
What term is used to designate an effector that is innervated by both parasympathetic and sympathetic divisions of the ANS?
multiautonomic output
Drugs that competitively block the action of acetylcholine at parasympathetic postganglionic effector cell receptors are called?
Anit-Muscarinic
Which pathways comprise the autonomic nervous system?
two-neuron chain from CNS to effector organs. Parasympathetic and Sympathetic.
A molecule that is released from synaptic vesicles and serves as the means of communication from one neuron to the next or from a neuron to an effector cell?
Neurotransmitter.
What Cellular acetylcholine receptor is found in effector organs of the parasympathetic system?
The M2 muscarinic acetylcholine receptor is the primary receptor found in effector organs of the parasympathetic system. Activation of this receptor leads to inhibition of adenylate cyclase and decreased intracellular levels of cyclic AMP, resulting in various physiological responses in target tissues.
What neurotransmitter is used by most postganglionic sympathetic neurons?
At the effector end (nerve to effector organ junction) the transmitter is Nor Adrenaline. However, at the nerve-nerve junctions (ganglions) the transmitter is Acetyl Choline.
Which nervous system dominates the control of effector organs under normal everyday conditions?
The autonomic nervous system dominates the control of effector organs under normal everyday conditions. It consists of the sympathetic and parasympathetic divisions, which work together to maintain homeostasis by regulating functions such as heart rate, digestion, and respiration without conscious effort.
What will happen if Acetylcholine receptors are destroyed?
If the acetylcholine receptor was destroyed that the effector cells cannot respond or detect the neurotransmitter, resulting in muscle paralysis.
Which component of the ans is characterized by ganglia located in or near effector organs?
The component of the autonomic nervous system characterized by ganglia located in or near effector organs is the parasympathetic nervous system. This system is responsible for promoting "rest-and-digest" functions, facilitating processes like digestion and energy conservation. The ganglia in the parasympathetic system are typically situated close to or within the organs they innervate, allowing for localized control.
What is a junction between two neurons or between a neuron and-an-effector?
A junction between two neurons or between a neuron and an effector is called a synapse. At this site, neurotransmitters are released from the presynaptic neuron and bind to receptors on the postsynaptic neuron or effector, facilitating communication. This process allows for the transmission of signals throughout the nervous system, influencing various physiological responses. Synapses can be either chemical, involving neurotransmitter release, or electrical, allowing direct ion flow between cells.
Is the brain an effector in the autonomic nervous system?
The brain is not an effector. An effector refers to the glands and muscles doing activity.
