Is this a stimulus or response your mouth watering at the sight of food on a plate?
This is a response, specifically a reflexive response known as salivation. The sight or smell of food triggers the brain to send signals to the salivary glands, causing the mouth to water in preparation for eating.
What part of the brain stimulates the physiologic response to stress?
The hypothalamus is a key brain structure that initiates the physiological response to stress. It activates the body's stress response system, known as the hypothalamic-pituitary-adrenal (HPA) axis, leading to the release of stress hormones like cortisol. This triggers the body's fight-or-flight response to help cope with the perceived threat.
Where is the fight or flight response controlled?
The fight or flight response is controlled by the sympathetic nervous system in response to perceived threat or danger. The amygdala in the brain plays a key role in initiating this response, which triggers a cascade of physiological reactions to prepare the body to either confront the threat or flee from it.
The fight or flight response triggers the release of?
The fight or flight response triggers the release of adrenaline and cortisol hormones from the adrenal glands. These hormones help prepare the body to either confront a threat or flee from it by increasing heart rate, blood pressure, and energy levels. Additionally, other hormones such as norepinephrine and epinephrine are also released to aid in the body's response.
What is the path of a nerve impulse from your leg to your brain and back to your leg?
A nerve impulse travels from your leg to your brain through sensory neurons. Once in the brain, the impulse is processed, and a response is generated. The response travels back to your leg through motor neurons to initiate movement or action.
What occurs when an infection changes the chemical environment of the brain changes?
Another way that infections injure the brain involves the way in which the chemical environment of the brain changes in response to the presence of an infection.
What is the information acquired by chemical stimuli or response to the environment that is directed by the brain?
It Is Sensory
Information acquired by chemical stimull or response to the environment that is directed to the brain?
sensory or synapse

What is a stimuli?
A stimulus is a detectable change in an organism's internal or external environment that leads to a response. It can be anything that triggers a reaction or behavior in an organism, such as a sound, light, smell, or touch.
Is tasting a lemon a stimulus?
Yes, tasting a lemon is a sensory stimulus that triggers a response in the taste receptors on the tongue. The sourness of the lemon elicits a specific taste sensation that is transmitted to the brain for interpretation.
Why do flashbacks occur?
Flashbacks occur when a person is reminded of a past event or experience, which triggers a vivid and involuntary recollection. This can happen due to emotional or sensory triggers, such as smells, sounds, or sights, that are linked to the memory. Flashbacks are a natural response of the brain to process and cope with traumatic or significant events.
What is sensor of negative feedback loops?
In negative feedback loops, a sensor is a component that detects a change in a system's internal or external environment. It then sends this information to the control center, which triggers a response to counteract the change and maintain homeostasis. The sensor plays a crucial role in providing feedback that helps regulate and stabilize the system.
What chemical in the brain triggers pleasure?
endogenous opioid peptides
What triggers sleep in human beings?
Your brain just shuts down and all your body follows your brain
Which body system is responsible for responding to the environment?
The nervous system is responsible for responding to the environment by processing sensory information and coordinating responses. It consists of the brain, spinal cord, and network of nerves throughout the body.
