What role does the nervous system play in muscle contraction?
controls the muscles by the motor nurons.
What role does the parasympathetic nervous system play in regulating heart rate?
The parasympathetic nervous system helps regulate heart rate by slowing it down. It works in opposition to the sympathetic nervous system, which speeds up heart rate.
Does the parasympathetic nervous system play a role in increasing digestion?
Yes, the parasympathetic nervous system plays a significant role in increasing digestion by stimulating the release of digestive enzymes and increasing blood flow to the digestive organs.
What role do the sensory organs play in the nervous system?
The sensory organs, such as the eyes, ears, nose, tongue, and skin, play a crucial role in the nervous system by detecting and transmitting information from the environment to the brain. This information is then processed by the brain to help us perceive and respond to our surroundings.
What is a sentence using the word central nervous system?
I've suffered some damage to my central nervous system.
Does the human nervous system remove wastes?
The human nervous system does not play a direct role in removing wastes from the body. Waste removal is primarily carried out by the urinary system, respiratory system, digestive system, and integumentary system.
What is the fundamental building block of the nervous system?
The fundamental building block of the nervous system is the neuron. Neurons are specialized cells that transmit information throughout the body via electrical and chemical signals. They play a crucial role in enabling communication within the nervous system.
How does the nervous system interact with the digestive system to regulate functions and responses related to digestion and absorption?
The nervous system communicates with the digestive system through a network of nerves called the enteric nervous system. This communication helps regulate functions like the release of digestive enzymes, movement of food through the digestive tract, and absorption of nutrients. The nervous system also plays a role in triggering responses such as the feeling of hunger or fullness.
Is ganglia an organ?
No, ganglia are not organs. They are clusters of nerve cell bodies located outside of the central nervous system. Ganglia are part of the peripheral nervous system and play a role in transmitting signals between the central nervous system and various parts of the body.
What percentage of the nervous system is made up of neurons?
Neurons make up only about 10% of the cells in the nervous system but they play a crucial role in transmitting and processing information. Glial cells, which provide support and protection to neurons, make up the majority of cells in the nervous system.
What cells type is the conductive cell of nervous system?
The conductive cells of the nervous system are called neurons. Neurons are specialized cells that are capable of transmitting electrical impulses and information throughout the body. They play a vital role in processing and transmitting signals in the nervous system.
