Is the autonomic nervous system primarily sympathetic or parasympathetic in its function?
The autonomic nervous system has two main branches: sympathetic and parasympathetic. The sympathetic branch is responsible for the "fight or flight" response, while the parasympathetic branch is responsible for the "rest and digest" response. Both branches work together to maintain balance in the body's functions.
What else can I help you with?
Is the vagus nerve sympathetic or parasympathetic in its function?
The vagus nerve is primarily parasympathetic in its function.
Dual innervation refers to an organ receiving?
Dual innervation refers to an organ receiving input from both the sympathetic and parasympathetic divisions of the autonomic nervous system. This allows for precise regulation of the organ's function by balancing the effects of these two opposing systems. Examples include the heart receiving both sympathetic stimulation (increasing heart rate) and parasympathetic stimulation (slowing heart rate).
What is dual innervation?
Innervated by both the sympathetic and parasympathetic nervous system. This allows for both branches of autonomic NS (sympathetic and parasympathetic) to precisely control an organ's activity.
What do the nerves in the autonomic nervous system do?
The autonomic system regulates contraction and secretion within the body.It regulates/controls:cardiac and smooth musclesecretions of the exocrine glandit controls some endocrine secretionsit controls some adipose tissue
What part of the brain controls the function of many internal organs?
The autonomic nervous system and its two divisions: the sympathetic and the parasympathetic, control the activities of the internal organs. The role of the sympathetic is to activate what is called the alarm response, and the parasympathetic activates the relaxation response. These two activities either turn on, or turn off, certain internal processes. All of these internal processes are regulated by the hypothalamus gland in the brain, which regulates homeostasis: the balance of the internal environment of a multi-cell organism.
Is the vagus nerve sympathetic or parasympathetic in its function?
The vagus nerve is primarily parasympathetic in its function.
The function of the autonomic nervous system in male reproduction?
The parasympathetic nervous system stinulates erection and the sympathetic nervous system stimulates ejaculation.

Which is NOT a function of the parasympathetic division of the ANS?
Which of WHAT?? You offer no CHOICES in your question to select from! Basically the sympathetic nervous system would not act to relax muscles in the body.
What are the two branches of the autonomic system?
The two integral parts of the autonomic nervous system are the sympathetic nervous system responsible for, "rest and digest" and the parasympathetic nervous system that is responsible for, "fight or flight".
What is the autonomic nervous system divided into?
I believe it's sympathetic and parasympathetic. Sympathetic is like the spark plug and gets the body revved up, the parasympathetic is like the brakes and slows the body down. That's how I learned it. Hope it's right. lol
Name the two branches of the autonomic nervous system and describe the function of each branch?
The two branches of the autonomic nervous system are the sympathetic and parasympathetic nervous systems. The sympathetic nervous system is responsible for the "fight or flight" response, increasing heart rate, dilating pupils, and releasing adrenaline. The parasympathetic nervous system is responsible for the "rest and digest" response, slowing heart rate, constricting pupils, and aiding in digestion.
Which major function of the nervous system is the autonomic operation.?
The autonomic operation of the nervous system primarily regulates involuntary bodily functions, such as heart rate, digestion, and respiratory rate. It controls the automatic processes that maintain homeostasis, functioning without conscious effort. The autonomic nervous system is divided into the sympathetic and parasympathetic divisions, which work together to respond to stress and maintain balance in the body.
Which organ is dually innervated?
The heart is an organ that is dually innervated, meaning it receives nerve supply from both the sympathetic and parasympathetic divisions of the autonomic nervous system. The sympathetic nervous system increases heart rate and contractility, while the parasympathetic nervous system, primarily through the vagus nerve, decreases heart rate. This dual innervation allows for fine-tuned regulation of cardiac function in response to varying physiological demands.
Autonomic function is controlled by what?
The autonomic nervous system (ANS) contributes to the stability of the internal environment of the body (homeostasis). The autonomic nervous system continuously makes adjustments to our body to maintain equilibrium. The ANS regulates cardiac and smooth muscles and glands. One example of the function of the autonomic nervous system is when our pupils constrict when bright light is shining into our eyes. There are two main branches of the autonomic nervous system, the sympathetic and parasympathetic.
Explain the control of cardiac activity by the autonomic nervous system?
The autonomic nervous system (ANS) regulates cardiac activity primarily through its two branches: the sympathetic and parasympathetic nervous systems. The sympathetic nervous system increases heart rate and contractility during stress or physical activity by releasing norepinephrine, while the parasympathetic nervous system, primarily mediated by the vagus nerve, decreases heart rate during rest through the release of acetylcholine. The balance between these two systems allows for the fine-tuning of heart function in response to the body's varying demands. This dynamic regulation ensures that adequate blood flow is maintained to meet the metabolic needs of tissues.
