To determine: The name of important neurotransmitters and paracrines that are responsible for bronchoconstriction and bronchodilation.
Introduction: Air travels to the lungs with the help of trachea (windpipe). The trachea divides into two branches which open in both the lungs. These branches are called bronchi. Bronchi are again divided into several bronchioles.
To determine: The name of receptors through which paracrine and neurotransmitters act.
Introduction: Paracrines are the hormones that diffuse from their from their target and target the nearby cells in the neighbourbood. The neurotransmitters are released by nerve cells at the empty space known as synapse, where they are taken by next nerve cell and the information is carried on.

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.arrow_forward
