The nervous system has 3 main functions: sensory, integration, and motor.
The four main functions of the nervous system are:
5 Major Functions of Nervous System
The nervous system is the major controlling, regulatory, and communicating system in the body. It is the center of all mental activity including thought, learning, and memory. Together with the endocrine system, the nervous system is responsible for regulating and maintaining homeostasis.
Breathing is an automatic and rhythmic act produced by networks of neurons in the hindbrain (the pons and medulla). The neural networks direct muscles that form the walls of the thorax and abdomen and produce pressure gradients that move air into and out of the lungs.
How the Nervous System Interacts with Other Body Systems
|Skeletal System||Bones (e.g., skull, vertebrae)|
|Cardiovascular System||Heart, blood vessels|
|Muscular System||Muscles (smooth, skeletal and cardiac muscles)|
The sympathetic nervous system (SNS) releases the hormones (catecholamines - epinephrine and norepinephrine) to accelerate the heart rate. The parasympathetic nervous system (PNS) releases the hormone acetylcholine to slow the heart rate.
The largest part of the brain, the cerebrum initiates and coordinates movement and regulates temperature. Other areas of the cerebrum enable speech, judgment, thinking and reasoning, problem-solving, emotions and learning.
When a message comes into the brain from anywhere in the body, the brain tells the body how to react. For example, if you touch a hot stove, the nerves in your skin shoot a message of pain to your brain. The brain then sends a message back telling the muscles in your hand to pull away.
Without food, you will have a harder time concentrating. That test you studied for at lunch is going to be just as hard if you don't give your brain the food it needs. Don't starve your brain!
Which is false about the brain stem? It's responsible for the brain's highest level of thinking and perception. False- while the upper parts of the brain tackle higher level matters, the brain stem is responsible for the most basic of body functions like breathing, food digestion and blood circulation.
The brain is protected by the bones of the skull and by a covering of three thin membranes called meninges. The brain is also cushioned and protected by cerebrospinal fluid. This watery fluid is produced by special cells in the four hollow spaces in the brain, called ventricles.
And here's a helpful tip these lobes are named according to their relation to the bones of the skullMoreAnd here's a helpful tip these lobes are named according to their relation to the bones of the skull. First up the frontal lobe which is this lobe right here located at the front of the hemisphere.
language and speech
In general, the left hemisphere or side of the brain is responsible for language and speech. Because of this, it has been called the "dominant" hemisphere. The right hemisphere plays a large part in interpreting visual information and spatial processing.
Discover just how powerful it is with these interesting facts.
Share on Pinterest. The theory is that people are either left-brained or right-brained, meaning that one side of their brain is dominant. If you're mostly analytical and methodical in your thinking, you're said to be left-brained. If you tend to be more creative or artistic, you're thought to be right-brained.

A 2013 study found Albert Einstein's brilliance may be linked to the fact that his brain hemispheres were extremely well-connected. The ability to use right-brain creativity and left brain logic simultaneously may have been what made Einstein a genius.
