Impulses are sent from the brain to the effector organs along what neurones?
Impulses are sent from the brain to the effector organs along motor neurons. These motor neurons are part of the peripheral nervous system and carry signals from the central nervous system to muscles and glands, allowing for coordinated movement and responses.
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 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 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.
Is a gland an effector?
A gland is not an effector in the traditional sense. Glands are organs that produce and secrete substances like hormones or enzymes, while effectors are typically muscles or glands that respond to a stimulus to produce a specific action or response.
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.
What are three examples of visceral effector organs?
Smooth muscles in the walls of blood vessels play a role in regulating blood pressure. Cardiac muscle in the heart is responsible for pumping blood throughout the body. Glands such as the pancreas secrete hormones and digestive enzymes in response to nervous system signals.
What is the nerves that send messages from the CNS to internal organs?
Motor Neurones send the impulse from the CNS to the effector muscle
Which pathways comprise the autonomic nervous system?
two-neuron chain from CNS to effector organs. Parasympathetic and Sympathetic.
What are effector organs for sight and sound?
It's not easy to be sure what is meant here. The sight organ is the eye, and the sound organ is the ear, but these are sense organs, i.e. they contain receptors. The larynx makes sound, and this could be classed as an effector if you shout in response to a stimulus, but you can't really think of sight in this way.
Impulses are sent from the brain to the effector organs along what neurones?
Impulses are sent from the brain to the effector organs along motor neurons. These motor neurons are part of the peripheral nervous system and carry signals from the central nervous system to muscles and glands, allowing for coordinated movement and responses.
What carries the nerve impulse from the central nervous system to an effector?
Nerve impulses are carried from the central nervous system to the effector organs (muscles or glands) by motor neurons. These motor neurons form a pathway known as the efferent pathway.
What is the correct sequence of events for a pathway showing feedback system?
In a feedback system, the sequence of events typically involves the initial stimulus activating a sensor, which then sends a signal to the control center. The control center receives the signal, processes the information, and initiates a response by sending signals to effector organs. The effector organs then carry out the necessary actions to counteract the initial stimulus, ultimately restoring balance to the system.
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.

Is a gland an effector?
A gland is not an effector in the traditional sense. Glands are organs that produce and secrete substances like hormones or enzymes, while effectors are typically muscles or glands that respond to a stimulus to produce a specific action or response.
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.
