What is the sequence of a typical reflex arc?
1. The receptor reacts to a stimulus. 2. The sensory neuron conducts the afferent impulses to the CNS. 3. The integration center consists of one or more synapses in the CNS. 4. The motor neuron conducts the efferent impulses from the integration center to an effector. 5. The effector, muscle fibers or glands, respond to the efferent impulses by contraction or secretion a product, respectively.
What is an organ that contains receptor cells called?
An organ that contains receptor cells is called a sensory organ. These organs perceive external stimuli such as light, sound, touch, taste, and smell and transmit this information to the brain for processing.
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.
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.
Is your tongue a tissue and organ or an organ system?
It is an organ. A tongue is an organ because a group of tissues makes up an organ. A tongue is more than a tissue, so it must be an organ. Each type of tissue in the tongue performs an essential task to help the tongue function properly.
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 organ in human biology?
Effector organ is a part of the body that responds to a stimulus and a stimulus is a change in the environment that is detected by a receptor. And is a receptor is a nerve cell that detects a stimulus.

An organ that contains receptor cells is called a sensory organ. These organs perceive external stimuli such as light, sound, touch, taste, and smell and transmit this information to the brain for processing.
What is the reflexes minimum components?
1. Receptor 2. Sensory (Afferent) Nerves 3. Intermediate Nerve Fiber (Association Nerves) 4. Motor Nerves 5. Effector Organ
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 is the sense organ of tasting?
The sense organ for tasting is the taste buds, which are located on the tongue and in other parts of the mouth. Taste buds contain receptor cells that detect different tastes, such as sweet, salty, sour, bitter, and umami.
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.
Is the receptor organ for hearing?
spiral organ of Corti
What is the reaction of an organism to stimuli?
For an instant, unlearned response, it does it with its reflex arc, which is made of 5 elements- (i)a receptor- a sensory organ, like an eye, ear, tongue or touch corpuscle (ii)sensory neuron, (iii)a coordinator neuron, (iv) a motor neuron and (v)an effector which normally is a muscle-either involuntary smooth or voluntary striped muscle. A receptor receives the stimulus, a sensory neuron carries the impulse in the form of an electric impulse, a coordinator neuron takes the necessary suitable action, a motor neuron carries the decision to the effector and finally the effector brings out suitable response. Lower animals lack an organized nervous system, but still the mechanism is more or less similar.
What is the receptor organ of the nose?
olfactory membrane
