are sensory cells located in the walls of blood vessels and the heart that detect changes in blood pressure. They send signals to the brain, which helps regulate blood pressure by adjusting heart rate and blood vessel diameter.
An example of a subjective symptom is
Dual innervation in the autonomic nervous system refers to the presence of both sympathetic and parasympathetic nerve fibers that innervate the same organ or tissue. These two divisions of the autonomic nervous system have opposing effects on the same target, with the sympathetic division typically stimulating or activating the target, and the parasympathetic division inhibiting or suppressing it. This balance between the two divisions is crucial for maintaining homeostasis in the body, and any disruption in this balance can lead to various physiological and pathological conditions.
parasympathetic reduces/decreases the BPM
The NS integrates and interprets sensory information, combining it with past experiences and memories to form a complete understanding of the current situation.
autonomic nervous system (ANS) and somatic nervous system (SNS)
which layer of the skin contains large blood vessels that transport nourishment to the skin?
where are the blood vessels found that transport nourishment to the skin and nerves
the term used to identify conditions that are brief and severe is
The NS helps maintain internal balance or homeostasis by monitoring and controlling vital functions such as heart rate, breathing, and body temperature.
sympathetic division of ANS and parasympathetic division of ANS
are specialized cells in the eyes that detect light and allow us to see. There are two types of photo receptors in the retina of the eye: rods and cones. Rods are responsible for vision in low-light conditions, while cones allow us to see colors and detail in brighter light.

A cyst is defined by which of the following descriptions

The antagonistic actions in the autonomic nervous system refer to the opposing actions of the sympathetic and parasympathetic divisions of the system on a given organ or tissue.The sympathetic division typically activates the "fight or flight" response, which involves an increase in heart rate, blood pressure, and respiration, as well as the release of glucose into the bloodstream. It also causes the relaxation of certain smooth muscles, such as those in the airways and blood vessels that lead to skeletal muscles, while causing the contraction of others, such as those in the blood vessels that lead to non-essential organs like the digestive system.In contrast, the parasympathetic division typically promotes a "rest and digest" response, which involves a decrease in heart rate, blood pressure, and respiration, and an increase in digestion and absorption of nutrients. It causes the constriction of pupils, and the stimulation of certain smooth muscles, like those that aid in digestion, and the relaxation of others, such as those in the airways and blood vessels that lead to skeletal muscles.Thus, the sympathetic and parasympathetic divisions have antagonistic actions on many organs and tissues, with one division stimulating and the other inhibiting the same process, to maintain a balance and regulate homeostasis in the body.Regenerate response
