Definition. noun, plural: effectors. (biochemistry) A molecule that binds to a protein and affects the function of that protein. (physiology) An organ, a gland, or a muscle that can respond and becomes active in response to a stimulus (e.g. nerve impulse)
What is a effector easy definition?
effector in American English 1. a muscle, gland, cell, etc. capable of responding to a stimulus, esp. to a nerve impulse.
What is a receptor or effector?
A receptor detects the stimuli and converts it into an impulse and an effector converts the impulse into an action. An example of a receptor is a light receptor in the eye which detects changes in light in the environment. An example of an effector is a muscle.
What is a effector in the nervous system?
Muscles and glands are called effectors because they cause an effect in response to directions from the nervous system. This is the motor output or motor function.What is effector in homeostasis?
An effector is any organ or tissue that receives information from the integrating center and acts to bring about the changes needed to maintain homeostasis. One example is the kidney, which retains water if blood pressure is too low.
What is an effector class 10?
An effector is a muscle, gland, or organ capable of responding to a stimulus, especially a nerve impulse. An effector brings about an action (e.g. a muscle action or glandular secretion) as a result of a stimulus it receives.
Is a sensory neuron an effector?
The primary components of the reflex arc are the sensory neurons (or receptors) that receive stimulation and in turn connect to other nerve cells that activate muscle cells (or effectors), which perform the reflex action.

effector A cell or organ that produces a physiological response when stimulated by a nerve impulse. Examples include muscles and glands.
What is PNS in nervous system?The Peripheral Nervous System (PNS) Peripheral nerves are an integral part of the human nervous system. The nervous system consists of: Central nervous system (brain and spinal cord)
Article first time published onWhat is effector in psychology?
n. 1. an organ, such as a muscle or a gland, that responds to neural stimulation by producing a particular physical response or initiating a specific physiological event.
What is the effector in the pupillary reflex arc?
:Pupillary Reflexes test both, the retina of the eye is the receptor, the optic nerve holds the afferent fibers, the oculomotor nerve contains the efferent fibers, and the smooth muscle of the iris is the effector organ.
Is skeletal muscle an effector?
Effectors include skeletal muscles, those under voluntary control as well as smooth muscles and cardiac muscles which are both under involuntary control.
Where is effector and receptor?
Receptors are found in sensory organs such as ears, eyes, nose, mouth and internal organs. They receive stimuli and convert into nerve impulse and send to the central nervous system for interpretation and processing. Effectors are the muscles and glands that produce an action in response to the stimulus.
What is the effector in body temperature?
3) Effector – Muscles and glands are the effectors as they respond to the signals from the brain to produce heat by shivering, or in the case of increased body temperature, to sweat as a way of cooling the body.
What is the role of the effector in a feedback loop?
An effector is the component in a feedback system that causes a change to reverse the situation and return the value to the normal range. In a negative feedback loop, a stimulus—a deviation from a set point—is resisted through a physiological process that returns the body to homeostasis.
What are the two types of effector?
The effectors. Are the organs that perform the responses of the Nervous System. There are two types of effectors, the muscles (also called “motor effectors”) and exocrine glands (also called “secretory efectors”).
What is the effector for the blood vessel constriction?
The effector for blood vessel constriction is smooth muscle. Smooth muscle is an involuntary muscle found in many parts of the body, including the lining of blood vessels.
Where is effector found in the body?
Effectors are parts of the body – such as muscles and glands – that produce a response to a detected stimulus. For example: muscle squeezing saliva from the salivary gland. a gland releasing a hormone into the blood.
Which neuron connects to effector?
Sensory neuron sends electrical impulses to a relay neuron, which is located in the spinal cord of the CNS. Relay neurons connect sensory neurons to motor neurons. Motor neuron sends electrical impulses to an effector.
Is ear is an effector?
Short Explanation: An effector organ is an organ that can respond to a stimulus from a nerve. … Receptors are often located in the sense organs, such as the ear, eye and skin. Each organ has receptors sensitive to particular kinds of stimulus.
What is meant by receptors and effectors Class 10?
Answer : A receptor is an organ or cell able to respond to heat, light or other external stimulus and transmit a signal to a sensory nerve. … An effector is a muscle, gland or an organ capable of responding to a stimulus, especially a nerve impulse.
What is a receptor give two examples of effectors?
What is a receptor? Give two examples of effectors. A receptor is sense organs and simple sensory nerve endings that go to the CNS. Two examples of effectors would be cells and organs.
What are receptor organs?
Receptor Organs: A receptor organ is one that detects changes in the external or internal environment. … Muscles, tendons, and joints contain sense organs which sense position of parts of the body. The internal organs detect stretch, a form of particular interest is the stretching of special parts of the arterial system.
What is the opposite of effector?
effectornoun. an organ (a gland or muscle) that becomes active in response to nerve impulses. Antonyms: receptor, sensory receptor, sense organ.

What is the meaning of control Centre?
noun. (US control center) A place from which an organization, activity, or system is centrally monitored and directed, or where operational devices and controls are housed.
What is difference between CNS and PNS?
The central nervous system includes the brain and spinal cord, while the peripheral nervous system includes all of the nerves that branch out from the brain and spinal cord and extend to other parts of the body including muscles and organs.
What are the divisions of the PNS?
The peripheral nervous system is further subdivided into an afferent (sensory) division and an efferent (motor) division. The afferent or sensory division transmits impulses from peripheral organs to the CNS.
What is the term used for bundles of fibers in the central nervous system?
In the central nervous system a bundle of axons is called a tract. Each axon is surrounded by a delicate endoneurium layer. The course connective tissue layer called perineurium, binds the fibers into bundles called fascicles.
What are the effectors of the sympathetic nervous system?
The effectors that respond to autonomic regulation include cardiac muscle ( the heart ) , smooth ( visceral ) muscles , and glands . These are part of the organs of the viscera ( organs within the body cavities ) and of blood vessels .
