What sends impulses from the accelerator center to increase heart rate?
Sympathetic
When the vasoreceptors in the aorta and the carotid artery sense an increase in blood pressure the medulla will relay what impulses?
Sympathetic impulses Source:Hole'sEssentials of human anatomy and physiology, 2006
What is an example of a blood reservoir?
Veins function as blood reservoirs. For example, in hemorrhage accompanied by a drop in arterial blood pressure, sympathetic nerve impulses reflexly stimulate the muscular wall of the veins. The resulting venous constrictions help maintain blood pressure by returning more blood to the heart. This mechanism ensures a nearly normal blood flow even when as much as 25% of blood volume is lost..
How many cranial nerves distribute sympathetic impulses?
1, 2, 4, 5, 6, 8, 11, 12
What stimulates norepinphrine?
Norepinephrine as a hormone is stimulated by epinephrine and angiotensin II. Norepinephrine as a neurotransmitter is stimulated by electrical impulses from the sympathetic nervous system.
What is the function of a nerve tissue?
to receive and conduct electrochemical impulses
What is the part of speech for impulses?
The word "impulses" can function as a noun, as it refers to sudden strong desires or urges to take a particular action.
What are the function of motor?
The function is to catch/take impulses from the central nervous system and send it to muscles and glands
What is the function of the sacral plexus?
Send impulses to the posterior side of the thigh.
How do sympathetic and parasympathetic nerve impulses affect the alimentary canal?
Sympathetic nerve impulses generally inhibit digestive functions by reducing peristalsis and secretions in the alimentary canal, promoting processes like the "fight or flight" response. In contrast, parasympathetic nerve impulses stimulate digestion by enhancing peristalsis and increasing the secretion of digestive enzymes and fluids, leading to a more active digestive process. Together, these two systems help regulate the balance between digestion and the body's other physiological needs.
What are the function of motor neuron?
The function is to catch/take impulses from the central nervous system and send it to muscles and glands
Function of peduncle?
The primary function of the peduncle is to control body movements. It sends nerve impulses from our brain to control our body.
