The nervous system

Question 1

what are the three principal functions of the nervous system

Answer 1

sensory input, integration and motor output

Question 2

what is sensory input

Answer 2

when the nerve detects a change in environment and send it to the brain

Question 3

what is integration

Answer 3

Integration is the body processes what to do.

Question 4

what is motor output

Answer 4

The response that occurs when your nervous system activates parts of your body

Question 5

what are the two parts of the nervous system

Answer 5

The central and peripheral

Question 6

what makes up the central nervous system

Answer 6

The spinal cord and brain

Question 7

what makes up the peripheral nervous system

Answer 7

all the nervous that branch off from the brain and spinal cord

Question 8

what are the two parts of the peripheral nervous system

Answer 8

Sensory and motor

Question 9

what does the sensory division do

Answer 9

The sensory division detects a change in the environment and sends it to the brain

Question 10

what does the motor division do

Answer 10

The motor division send signals from your brain to your muscles and glands

Question 11

what are the two parts of the motor division

Answer 11

The somatic and autonomic

Question 12

what does the somatic nervous system do

Answer 12

this is the part that send your voluntary signals to your muscle

Question 13

what does the autonomic nervous system do

Answer 13

This is the part that send your involuntary signals to your lauges heart and stomach.

Question 14

what are the two parts of the autonomic nervous system

Answer 14

sympathetic and parasympathetic

Question 15

what does the sympathetic nervous system do

Answer 15

It releases adrenaline and makes you do stuff

Question 16

what does the parasympathetic nervous system do

Answer 16

It calms you down and controls homeostasis.

Question 17

what are the different glial cells in your central nervous system

Answer 17

astrocytes, microglial cells, ependymal cells and oligodendrocytes

Question 18

what does astrocytes do.

Answer 18

they connect the neurons to the blood supply and govern the exchange of materials between neurons and capillaries

Question 19

what does microglial cells do.

Answer 19

they protect it from intruders

Question 20

what does ependymal cells do

Answer 20

they line cavities in your brain and spine and release spinal fluid to cushion the two organs.

Question 21

what does oligodendrocytes

Answer 21

they rap around neurons to create an insulating sheet that speeds up the efficiency and speed of the signal.

Question 22

what are the different types of glial cells in your peripheral nervous system

Answer 22

satellite cells and schwann cells

Question 23

what does satellite cells do

Answer 23

they connect the neurons to the blood supply and control the amount of resources they get

Question 24

what does schwann cells

Answer 24

They rap around one specific part of the neurons to create an insulating sheet that speeds up the efficiency and speed of the signal.

Question 25

what are the different parts of a neuron

Answer 25

you have the cell body which is big round thing, then there are the dendrites which are the spiky thing that protrude from the cell body and your have the axon that is the long extension from the cell body.

Question 26

what is a multipolar neuron and where do you find them

Answer 26

a multipolar neuron with three processes for example one axon and lots of dendrite. these often interneurons or motor neurons.

Question 27

what is a bipolar neuron and where do you find them

Answer 27

has two processes for example a dendrite and an axon. these are very rare and are only found in the olfactory epithelium, the retina of the eye, and ganglia of the vestibulocochlear nerve

Question 28

what is a unipolar neuron and where do you find them

Answer 28

a unipolar has one process. they are often found in sensory.

Question 29

where does the nerve send and receive information

Answer 29

the information is received at the dendrites and sent at the axon

Question 30

How do nerves communicate

Answer 30

There is a gap between the two neurons called the synapse where a chemical signal (neurotransmitters) is transmitted from sacks on the presynaptic neuron to reseptercits on the postsynaptic neuron.

Question 31

what are the two different types of signals that a axon can send.

Answer 31

Depending on the type of neurotransmitter it will either have an excitatory effect (continuing the signal) or an inhibitory effect (stopping the signal)

Question 32

what does S-A-M-E mean

Answer 32

Sensory = afferent

Motor=Efferent

Question 33

what is the fight-flight response

Answer 33

The fight or flight response is referring to the response the the sympathetic nervous system has to an threat, you can confront or you can run.

Question 34

How do you think you went on these three topics.

Answer 34

Good I think I have all the flash cards I need and I put in enough effort.
