What is the purpose of a sensory receptor?
Expert Solution & Answer
Summary Introduction
To review:
The purpose of a sensory receptor.
Introduction:
The sensory receptor is a part of the PNS (peripheral nervous system). These receptors are present at the surface of neurons to sense external as well as internal environmental changes.
Explanation of Solution
The sensory receptor is classified as the component of nervous system, responsible for detecting the changes occurring in the external as well as the internal environment.
The sensory receptors help to monitor the internal stimuli like a decrease in the BP (blood pressure) or the external stimuli such as an insect bite on the skin. Without the sensory receptors, the brain will not get any information about the internal or the external stimuli and the changes, which occur due to the stimuli.
Conclusion
Thus, the purpose of a sensory receptor is to detect the changes that occur in the external and the internal environment of the body and inform the brain about these changes.

Problem 1 (Mental Health): The survivor victim is dealing with acute stress and symptoms of a
post-traumatic stress disorder (PTSD) due to their traumatic experience during the January 2025 wildfire.
Goal 1: To alleviate the client's overall level, frequency, and intensity of
anxiety and PTSD symptoms so that daily functioning remains
unimpaired.
Objective 1: The client will learn and regularly use at least two anxieties
management techniques to reduce anxiety symptoms to less than three episodes per week.
Intervention 1: The therapist will provide psychoeducation about anxiety and
PTSD, including their symptoms and triggers. The therapist will also teach and assist the client in adopting relaxation techniques, such as deep breathing exercises and progressive muscle relaxation, to better manage anxiety and lessen PTSD symptoms.
