Is the vagus nerve the heart rate centre of the brain?
koban [17]

Answer:

The vagus nerve has two bunches of sensory nerve cell bodies, and it connects the brain stem to the body. It allows the brain to monitor and receive information about several of the body’s different functions.

Explanation:

The vagus nerve is the longest and most complex of the 12 pairs of cranial nerves that emanate from the brain. It transmits information to or from the surface of the brain to tissues and organs elsewhere in the body.

There are multiple nervous system functions provided by the vagus nerve and its related parts. The vagus nerve functions contribute to the autonomic nervous system, which consists of the parasympathetic and sympathetic parts

The vagus nerve has a number of different functions. The four key functions of the vagus nerve are:

-Sensory: From the throat, heart, lungs, and abdomen.

-Special sensory: Provides taste sensation behind the tongue.

-Motor: Provides movement functions for the muscles in the neck responsible for swallowing and speech.

-Parasympathetic: Responsible for the digestive tract, respiration, and heart rate functioning.

What is not an example of negative feedback
svetoff [14.1K]
<h2>Answer:</h2>

<u>Blood clotting</u> is a positive feedback.

<h2>Explanation:</h2>

All the physiological process occurring in the body are monitored by two types of mechanism called negative feedback and positive feedback.  

Positive feedback is the reaction which occurs with the feedback from the actions the system has performed. The blood clot occurs with palette formation which is regulated with the blood lose (continuous feedback).

Negative feedback is a reaction that is the invert of the change distinguished, meaning it capacities to decrease the change. A change is recognized by a receptor and an effector is made to incite a contrary impact which facilitates further reaction.  

The physiological process such as shivering, sweating and digestion are examples of negative feedback.
