Stimulus (physiology) In physiology, a stimulus (plural stimuli) is a detectable change in the internal or external environment. The ability of an organism or organ to respond to external stimuli is called sensitivity.When a stimulus is applied to a sensory receptor, it normally elicits or influences a reflex via stimulus transduction.ne internal stimulus that causes hormone release is blood pressure. Hypotension, or low blood pressure, is a large driving force for the release of vasopressin, a hormone which causes the retention of water in the kidneys.

Endocytosis Photo by: abacus. The ability to internalize material from outside the cell is important for several cellular processes including the ingestion of essential nutrients, removal of dead or damaged cells from the body, and defense against microorganisms.

stimulus Plural stimuli (stĭm'yə-lī') Physiology Something that can elicit or evoke a physiological response in a cell, a tissue, or an organism. A stimulus can be internal or external. Sense organs, such as the ear, and sensory receptors, such as those in the skin, are sensitive to external stimuli such as sound and touch. Something that has an impact or an effect on an organism so that its behavior is modified in a detectable way.

- Internal cues where things like the hunger pains I thought I was having when my hormones gremlin and leptin went to war or my body’s confusion of thirst vs. hunger. External cues were the triggers in my environment. These were easier to control when I learned what they were and started changing my habits and behaviors.

- The nervous system responds to external signals through nerve cells or nerve fibers (neurons). Receptors also feed signals into the system from the environment. Collectively, sensations from the external environment are collected and sent to the CNS from extero, vicero and propioreceptors through sensory neurons.

- Plants use direct environmental stimuli for orientation in growth and movement. This is called tropism. The responses of the plant may be toward (positive) or away (negative) from the external stimulus or stimuli.Click the links below to learn more about the different types of stimuli and the plants reaction to it:Phototropism-Reaction to light and different wavelengths.ell, it has all to do with stimulus receptors and with plant hormones. The perception of plants (plant physiology) is the ability to sense environmental stimuli and to adequately and most beneficially react to them. Plant stimuli receptors act on a cellular level and their nature depends upon the kind of stimulus.

- Yet, there are big changes going on outside your body. •You need to detect a change in the environment (a. stimulus) and react to the change (a response) in a way. that maintains homeostasis. When you do this without. thinking, it is called a reflex.

- The graphic above shows the response of a human to being struck on the knee with a hammer. A change in the environment is called a stimulus. In this situation, the stimulus is the being struck with the hammer. A response is the manner in which the organism reacts to the stimulus.

stimulus liminal stimulus A stimulus of an intensity such that it just provokes a response that is at threshold. Syn. threshold stimulus. threshold stimulus See liminal stimulus.timulus. adequate stimulus a stimulus of the specific form of energy to which a given receptor is sensitive. aversive stimulus one which, when applied following the occurrence of a response, decreases the strength of that response on later occurrences.

What is a noxious stimulus? We characterize stimulus in terms of the external cause and either the subjective experience or the behavioral response to which it gives rise or, in the case of noxious or non-noxious stimuli, in physiology, we could say that it is an external event or agent that gives rise to discharge in an afferent nervous system.

definitions - feedbackreport a problem In psychology, the body receives a stimulus from the environment or internally that causes the release of hormones. Release of hormones then may cause more of those hormones to be released, causing a positive feedback loop. This cycle is also found in certain behaviour.

Chapter 39 - Plant Responses to Internal and External Signals Plant hormones help coordinate growth, development, and responses to environmental stimuli. 1  In general, plant hormones control plant growth and development by affecting the division, elongation, and differentiation of cells. One part of a plant can send signals to other parts. 2  Plants can sense gravity and the direction of light. 3  A plant’s morphology and physiology are constantly tuned to its variable surroundings by complex interactions between environmental stimuli and internal signals.

- This realization is triggered by either an internal or an external stimulus. An internal stimulus is related to something the buyer feels, such as hunger or thirst. An external stimulus comes from outside the buyer, including advertising, recommendations, and store displays.

- In the case of associative learning, however, the new behaviour is acquired through an internal learning mechanism. This in-built mechanism for acquiring information allows the individual to modify its response to a stimulus.

Internal and external fertilisation? Best Answer: Internal fertilization is when the sperm is directly deposited into the female, who produces eggs and fertilizes them in her body.External fertilization is when the sperm and eggs are released outside of the body and meet outside of the body, not like how chithra described.Birds do not have external fertilization, the fertilization still occurs in the body, they just do not produce live young.xternal fertilization is when the sperm and eggs are released outside of the body and meet outside of the body, not like how chithra described. Birds do not have external fertilization, the fertilization still occurs in the body, they just do not produce live young.

- There are benefits and pitfalls to both internal and external sourcing. The most important factor, of course, is selecting the best candidate for the job. Internal promotion may look like a cost effective method for filling a role, however it can also run the risk of costing you much more in the long run.hen internal sourcing (or promotion) is a part of strong succession planning efforts, it can pay off beautifully when selections are made according to sound selection processes. Selecting an internal candidate comes with cautions, however.

- Similar to children who experience externalizing behaviors, children with internalizing behaviors are more likely to be rejected or disliked by both their fellow peers and adults. They also experience negative emotional outcomes including depression, feelings of loneliness, negative self-image, and negative self-worth.ifference between Internalizing and Externalizing Behaviors. Externalizing and internalizing behaviors both result from negative responses to stress. Unlike internalizing behaviors, externalizing behaviors are focused outside of oneself. They include: 1  Physical aggression. 2  Destruction of property.
