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.

What structures and functions of the nervous system are affected by meningitis?
It can do brain damage to your brain. The cause of it is viruses, fungi, normally bacteria.
Well, Meningitis is caused by bacteria flooding the cerebrospinal fluid which is found in between the meninges (layers of membranes surrounding the brain and the spinal cord) so I'd say that Meningitis can do damage to the brain and the spinal cord.
Functions of cerebellum in nervous system?
The most important function of the cerebellum (if your a student the most you will probably be tested on in a gen bio class) is the control of balance and fine motor function, like walking.
Name the two types of nervous tissue?
Neurons and neuroglia the neuron known as the functional unit is the actual nerve cell. It transmits the impulses of the nervous system.. A neuron consists of three basic parts: a cell body, one axon, and one or more dendrites..
What is the division of the nervous system that helps the body react to pain is the?
The division of the nervous system that helps the body react to pain is known as the sympathetic nervous system. This is what will trigger responses to stressful situations.
When you learn something new do you grow new neurons?
That is a complicated and very good question. In humans (mammals) neurons are formed during development throughout the cortex. At adulthood, this continues only in the hippocampus and olfactory bulb. Therefore the rest of the cortex is made of all the same neurons for the rest of your life (n.b. you can lose them). Therefore learning new things is probably the result of neuro-placticity rather than neurogenesis.
However, There are two general types of memory; episodic and semantic. Episodic are the ones that you can imagine because you experienced them. As opposed to semantic- dry info you've studied.
Episodic memories seem to be consolidated by the hippocampus which may play memories back during REM sleep. This may be the result of neurogenesis. However, the new cells that are formed will not be the loci of the memories they are the mechanism of storing the memories in the neocortex.
Long term effects of exercise on tendons?
Can wear away the muscle walls and lead to aches and pains that build up gradually over time. This can cause discomfort if one indulges in over exercise, so its best to do everything in moderation and not push yourself beyond the limits. Joint pain- arthritis is common and stiffness may occur if care isn't taken.
What body system is the fast-acting control system?
The nervous system is the fast-acting control system.
How many pairs of nerves branch off of the spine?
SPINAL CORD31 Pairs - Spinal NervesCervical8 pairThoracic12 pairLumbar5 pairSacral5 pairCoccyx1 pair
What is the main function of the perpheral nervous system?
The main function of the peripheral nervous system is to connect the central nervous system to the limbs and organs. It helps coordinate body movements and receiving external stimuli.
It is also the system that controls the "fight or flight" response.
The central nervous system is responsible for coordinating all the information that is received from the body, whereas the peripheral nervous system connects the central system to the organs and limbs, relaying communication to and fro.
How can alcohol effect homeostasis?
Yes to put it simply. Alcohol blocks the receptors that tell your body when your bladder is full, so your bladder keeps thinking it is full when it is not, this can cause dehydration, which can cause headache as seen in hangovers
How do the organs of the nervous system work together?
The central nervous system is the brain and the spinal cord, and the peripheral nervous system is the motor and sensory neurons. So your sensory neurons are what help you feel things, like cold and hot and pain, etc. This is a pretty open-ended question, but I would say they keep us alive when they work together by alerting of us of our environment.
What is the role of the neurons in transmitting electrochemical impulses?
They send the chemical impulses that are released at the synapses from the synaptic terminal of the axon of the first neuron. It merges from the dendrites to the second neuron.
Table of the nervous system responsablefor maintaining the internal temperature of the body?
The Hypothalamus controls body temperature, thirst, fatigue etc
How was the nervous system formed?
The brain is the result of the evolution through natural selection over many millions of years.
What are neurons that detect stimuli in the environment?
They are nerves. These nerves tell us exactly what we feel, and then send that information to the brain.
What gland directly stimulated by the nervous system to secrete hormones?
adrinal gland stimulates the nervous system
What part of the central nervous system interprets information collected be the senses?
by the brain throught the heart

What are the primitive reflexes of a newborn?
All living things have reflexes. If you get something in your eye, you blink. That's a reflex. If you get hit on the nerve in your knee, you leg jumps. It's part of being alive. Doctors test babies' reflexes to determine if they are neurologically normal.
How does information get from receptors to the central nervous system?
The information gets from the receptors to the central nervous system by traveling from one neuron to another through a process in which neurotransmitters are released at synapsis between the neurons.
