Typically, the term "effector" is used to describe the final structure in a reflex pathway--the structure that actually does the work. What "work"? It depends on the context.
For example, in a reflex that ends in movement of a limb (like bending the arm) the effector would be the skeletal muscle that contracts and causes the limb to move.
There are seven steps in the simplest reflex pathway:
- Stimulus
- Sensory receptor
- Afferent (sensory) pathway
- Integrating center
- Efferent (motor) pathway
- Effector
- Response
In the endocrine system, the term "effector" could be used to describe the tissues that the hormones act on. It is also possible, depending on the context, that "effector" could be used to describe the endocrine gland itself. See the following examples:
Blood sugar regulation
- Stimulus = high blood sugar
- Sensory receptor = beta cells of pancreas
- Afferent pathway = second messengers in beta cells
- Integrating center = beta cells of pancreas
- Efferent pathway = insulin traveling in the bloodstream
- Effector = many body tissues (e.g. adipose tissue) with insulin receptors
- Response = uptake of glucose (sugar) from the bloodstream
Adrenaline release (fight or flight response)
- Stimulus = fearful sight or sound (e.g. the screech of braking tires, or the sight of a dog coming after you)
- Sensory receptor = Hair cells in the cochlea, or rods & cones in the eyes
- Afferent pathway = sensory neuron (cranial nerve VIII if sound, CN II if sight)
- Integrating center = brain, esp. hypothalamus
- Efferent pathway = sympathetic neuron (part of autonomic nervous system)
- Effector = adrenal gland
- Response = release of adrenaline (epinephrine) into bloodstream
I hope you can see what I mean by context. The release of epinephrine will start a whole new reflex pathway! It depends on where you begin.

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.
When the parasympathetic division is stimulated what neurotransmitter is released at the effector organ?
Acetylcholine is the main neurotransmitter released at the effector organ when the parasympathetic division is stimulated.
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.
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.
When was Effector - album - created?
Effector - album - was created in 1999.
Cells that carry out a response to a stimulus are called?
effector
What is the effector muscle of a biceps reflex?
The effector muscle is the biceps brachii.
What is the difference between a stimulus impulse receptor and effector?
A Receptor is referring to a sense organ, like a nerve ending. An Effector is referring to a muscle capable of reflecting to a stimulus. By definition, receptor and effector are antonyms.
What is an effector cell?
The effector cell responds to a nerve impulse and can be either a muscle cell or a gland cell.
What is the gap between a neuron and its effector?
The gap between a neuron and its effector is called a synaptic cleft. Neurotransmitters are released from the neuron into this gap and then bind to receptors on the effector cell to transmit the signal.
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.
What is the effector of a nose?
The effector of the nose is the muscles that control the movement of the nostrils and the upper lip, allowing for actions like flaring the nostrils or wrinkling the nose. The effector muscles work in response to signals from the brain to adjust the position and shape of the nose.
What is the function of effector in a neuron?
The effector in a neuron is the structure that carries out the response generated by the neuron in order to stimulate a target such as a muscle or gland. Effector neurons transmit signals from the central nervous system to these targets to produce a specific physiological response.
What tissue is the effector when you get stabbed with a nail?
Muscle tissue would be the effector in this scenario, as it contracts and moves in response to the stimulus of getting stabbed with a nail.
