Adequate stimulus denotes that physico-chemical stimulus, for whose reception a sensory receptor is specialized and responds to at the lowest possible intensity (energy). What is adequate stimulus of a receptor?
The adequate stimulus is a property of a sensory receptor that determines the type of energy to which a sensory receptor responds with the initiation of sensory transduction. … The adequate stimulus is the amount and type of energy required to stimulate a specific sensory organ.

What is the adequate stimulus for stimulation of the retina?

Thus, the adequate stimulus for the eye is photic (light) energy. … Although mechanical pressure on the eye or an electrical shock can stimulate the retina and produce sensations of light, these are not adequate stimuli for the eye. What does inadequate stimulation mean?
A term sometimes used for a stimulus (1) that is incapable of evoking a response from an organism, such as light or sound that is too faint for the visual or auditory receptors to detect.

What is threshold stimulus?

n. A stimulus that is just strong enough to evoke a response. What are the types of stimulus?

There are two main types of stimulus –the external stimulus and the internal stimulus.

Frequently Asked Questions(FAQ)

What is the adequate stimulus for photoreceptors?

Receptors normally respond to only one type of stimuli (or sensory modality), and that type of sensory modality is called the adequate stimulus for a particular type of stimulus. For example, the adequate stimulus for the eyes photoreceptors (rods and cones) is light and not touch (mechanical stimuli).

What are the 5 types of stimuli?

Our brains commonly receive sensory stimuli from our visual, auditory, olfactory, gustatory, and somatosensory systems.

What is the adequate stimulus for hearing?

Each type of receptor has a particular stimulus it responds to, called the adequate stimulus. Hair cells are responsible for hearing and respond to vibrations in the air, or sound. Photoreceptors called rods and cones are responsible for vision in the retina and respond only to visible light.

When an adequate stimulus is applied to an axon?

Question: When an adequate stimulus is applied to an axon The amplitude of the action potential is directly proportional to the strength of the applied stimulus The amplitude of the action potential is inversely proportional to the strength of the applied stimulus The speed of the nerve impulse conduction is inversely …

What is the adequate stimulus for taste?

Which type of stimulus can the eye detect?

Light The table shows the stimuli which cause receptor cells in the sense organs to produce impulses. … Sense organs.

Sense organ Stimulus
Skin Temperature, pressure and pain
Tongue Chemical tastes (in food and drink)
Nose Chemical smells (in the air)
Eye Light

What do you think is the adequate stimulus for sensory receptors in the ear?

An adequate stimulus for sensory receptors in the ear is the moderate pressure, and an inappropriate one is intense pressure.

What is stimulus transduction?

Transduction in the nervous system typically refers to stimulus-alerting events wherein a physical stimulus is converted into an action potential, which is transmitted along axons towards the central nervous system for integration. It is a step in the larger process of sensory processing.

What is an example of inadequate?

The definition of inadequate is someone or something that is lacking in something desired or required. An example of something that would be described as inadequate is a broken down car that won’t run.

What B means lacking stimulating characteristics?

bland bland, flat. lacking stimulating characteristics; uninteresting. dry, juiceless. lacking interest or stimulation; dull and lifeless. vapid.

Can lack of stimulation cause depression?

Your boredom may be related to depression if you experience the following symptoms: feeling hopeless. feeling sadness. evading opportunities for stimulation.

What is the maximum stimulus?

$1,400 stimulus check income limits

Full $1,400 per person maximum (based on AGI) Not eligible (based on AGI)
Single taxpayer Less than $75,000 $80,000 or more
Head of household Less than $112,500 $120,000 or more
Married couple filing jointly Less than $150,000 $160,000 or more

What is an example of a threshold stimulus?

Stimulus Threshold refers to the minimum intensity required from a stimulus to produce a response from a human or an animal. It is also the point where a human or an animal first senses and responds to a stimulus. For example, imagine someone puts sand in the palm of your hand, one grain at a time.

What is the difference between threshold stimulus and maximal stimulus?

The threshold stimulus voltage is determined by raising and lowering the stimulus voltage a little to find the voltage at which the CAP is just discernible. The maximal stimulus voltage is the point at which a further increase in stimulus voltage produces no further increase in the CAP amplitude.

How does stimulus affect the nervous system?

They detect a change in the environment (stimulus). In the nervous system this leads to an electrical impulse being made in response to the stimulus. … Receptors.

Sense organ Stimuli receptors respond to
Eye Light
Ear Sound, position of head

What is the response to a stimulus called?

Automated response to a stimulus is reflex.

What are three examples of stimulus and response?

Examples of stimuli and their responses:

Is skin a receptor?

The skin possesses many sensory receptors in the epidermis, dermis, and hypodermis, which allows for discrimination of touch such as pressure differences (light vs. deep). Other qualities of the external world assessed by skin sensory receptors includes temperature, pain, and itch.

What are the 6 sensory receptors?

Terms in this set (7)

What are the 4 types of receptors?

Receptors can be subdivided into four main classes: ligand-gated ion channels, tyrosine kinase-coupled, intracellular steroid and G-protein-coupled (GPCR). Basic characteristics of these receptors along with some drugs that interact with each type are shown in Table 2.

What is the difference between stimulus and stimuli?

A stimulus is anything that can trigger a physical or behavioral change. The plural of stimulus is stimuli. Stimuli can be external or internal.

What are the 3 types of stimuli?

excited by three types of stimuli—mechanical, thermal, and chemical; some endings respond primarily to one type of stimulation, whereas other endings can detect all types.

What is the behavior for a stimulus?

In psychology, a stimulus is any object or event that elicits a sensory or behavioral response in an organism. … In behavioral psychology (i.e., classical and operant conditioning), a stimulus constitutes the basis for behavior.
