Nervous System
This category is for questions about the mechanical and chemical process of reactions to internal and external stimuli, ranging from the brain down to the spinal cord, and all nerves, cells and tissues in between.

If your body starts to feel relaxed what part of the nervous system is becoming more active?
Parasympathetic nervous system helps your body start to feel relaxed as your nervous system becomes more active.
What neurons are part of the peripheral nervous system?
The two parts of the peripheral nervous system are somatic and visceral.
P.S.- The former innervates the skin,joints and muscles whereas the latter to the internal organs, blood vessels and glands. The latter is divided into sympathetic and parasympathetic (like the reins of a horse).
What is the Motor function of nervous system?
To controle your motor skills, Dexterity,distance, strength,etc..
The control center of your nervous system?
The brain and Spinal Cord
As the most complex system, the nervous system serves as the body control center and communications electrical-chemical wiring network.
brain
Which division of the autonomic nervous system does epinephrine imitate?
The sympathetic (fight or flight) system.
What synapse is more common in embryonic nervous tissue than in adults?
They permit the exchange of guiding clues during early neuronal development so that neurons can connect properly with one another.
Why is the autonomic nervous system so named?
autonomic nervous system refers to visceral organs that we are unable to control. these organs control actions such as breathing, heart rate, etc. that occur without having to be thought about
What part of the brain regulates visceral activities and involuntary results?
The heart controls all activity and function of viscera. The heart is located in the autonomic nervous system.
What is a change or signal in the environment that makes the nervous system react?
The brain is the organ that signals the body to react to changes. Your senses help you react to your environment by detecting the change. When you see danger coming, your brain is triggered to respond accordingly.
What are the medical problems of the nervous system?
this website is a piece of crap anybody who ask this questions will not get a correct answer
What are the two neurohormones found in sympathetic or adrenergic nerves?
Epinephrine or adrenaline, and non epinephrine or noradrenaline.
In what way does the nervous system connect to the skeletomuscular?
The nervous system sends signals to make muscles move....Apexxx
Specialized cells that myelinate the fibers of neurons found in the pns?
Peripheral Nervous System= Oligodendrites
Central Nervous System= Schwaan Cells
Oligodendrites myelinate 250 times faster than Schwaan cells
How does the brain know when you have stepped on a sharp object?
Nerve cells in the foot sense injury, and using electrical impulses, transmit relevant information, through the nervous system, to the brain. The brain translates the impulses as pain.
What neurons does the nervous system repair?
Yoga is the body abel to repair damage to the parts of the nervous system
How does your brain communicate with your body?
I think the answer you're looking for is nerves. Nerves are the types of cells that transmit signals from your body to your brain, and brain to your body. Nerve cells release charged molecules in a controlled way to create electrical signals that can propagate information across the body.
Explain the structural and functional classification of nervous system?
The STRUCTURAL CLASSIFICATION of the nervous system includes all of the nervous system organs. It also has two subdivisions, the CNS and the PNS. The CNS consist of the brain and the spinal cord, both interpret incoming sensory information and issue instructions based on past experience. The PNS consist of nerves that extend from the brain and spinal cord, these nerves serve as communication lines.
The FUNCTIONAL CLASSIFICATION of the nervous system divides the PNS structures into two principal subdivisions. The first of which is called the SENSORY, OR AFFERENT DIVISION, it keeps the CNS constantly informed of events going on both inside and outside the body. The MOTOR/EFFERENT DIVISION, carries impulses from the CNS to effector organs, the muscles, and glands. These impulses activate muscles and glands, thus creating a "motor response."
I got this information almost word for word from my anatomy and physiology book, and my brain :P
