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 receptor and effector?
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 are the receptor cells?
Receptors. Receptors are groups of specialised cells. They detect a change in the environment (stimulus) and stimulate electrical impulses in response. Sense organs contain groups of receptors that respond to specific stimuli.
What is the function of receptor and effector in our body?
Receptors receive stimuli from the surrounding environment and send the messages conveyed by them to the spinal cord and the brain as electrical impulses through the sensory nerves. On the other hand, effectors respond to stimuli according to the instructions sent from the nervous system.
What is meant by receptors and effectors give examples?
Example: The eyes have light receptors which can detect light and the ears have sound receptors which can detect sound. An effector is a part of body which can respond to a stimulus according to the instructions given from the nervous system. Example: Muscles and glands of the human body.
What is effector and examples?
Effectors are parts of the body – such as muscles and glands – that produce a response to a detected stimulus. For example: a muscle contracting to move an arm. muscle squeezing saliva from the salivary gland.
Where are receptor cells?
Receptor cells are found throughout the body in areas that detect stimuli. Therefore, receptor cells that detect light are found in the retina layer… See full answer below.
Is the eye an effector?
The eye responds to bright light to protect the retina from damageThe bright light triggers a reflex that makes the pupils smaller, meaning less light enters the eyeAs with all reflexes, there is a stimulus, receptor and effectorThe stimulus is the light, the receptor is the light receptors in the eye and the effectors …
What are the 3 types of receptors?
There are three general categories of cell-surface receptors: ion channel-linked receptors, G-protein-linked receptors, and enzyme-linked receptors.
What is the 2 examples of receptors?
Receptor : Example – Muscles, glands, etc. Definition – Receptor are the molecules which present on the surface of the cell membrane of a particular cell. A receptor is sensitive to a specific stimulus. Example – Smell receptors of noses, the light receptor of noses (so that we can see an object), etc.
What are receptors do?
Receptors are a special class of proteins that function by binding a specific ligand molecule. When a ligand binds to its receptor, the receptor can change conformation, transmitting a signal into the cell. In some cases the receptors will remain on the surface of the cell and the ligand will eventually diffuse away.
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”). All effectors are stimulated by nerves ie are “innervated”.
What do effector cells do?
In the immune system, effector cells are the relatively short-lived activated cells that defend the body in an immune response. Effector B cells are called plasma cells and secrete antibodies, and activated T cells include cytotoxic T cells and helper T cells, which carry out cell-mediated responses.
What tissue is the effector?
An effector is a tissue structure, namely a muscle or gland, that responds to an efferent impulse. An efferent impulse is a biochemical and electrical impulse that travels via nerve fibers away from the central nervous system. The central nervous system is a term for the brain and spinal cord.
How receptors of nervous system communicate with effectors?
Answer: 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.
Are examples of effectors of the nervous system?
effector A cell or organ that produces a physiological response when stimulated by a nerve impulse. Examples include muscles and glands.
What are receptors in Homeostasis?
Components of homeostasis
– A receptor; – A control centre; – An effector. These components do specific jobs that allow regulation of the internal environment. A receptor detects external changes that could influence the internal environment.
What is PNS in nervous system?
The peripheral nervous system consists of the nerves that branch out from the brain and spinal cord. These nerves form the communication network between the CNS and the body parts. The peripheral nervous system is further subdivided into the somatic nervous system and the autonomic nervous system.
What is the main difference between the CNS and PNS?
Central and peripheral nervous systems collectively make up the nervous system in vertebrates. The CNS comprises the brain and spinal cord. The PNS comprises somatic and autonomic nervous systems. The PNS is involved in the transmission of sensory impulses from its sensory receptors into the CNS.
What are the differences of PNS and CNS as to function?
Definition, Parts and Function
The CNS is made up of the brain and the spinal cord components. The PNS is all the nerves that branch out from the CNS components and extend to other parts of the body – to the sense organs, muscles, and glands. The PNS connects the CNS to the rest of the body.
