Nervous system tree | Cns central nervous system the brain and spinal cord |
Pns peripheral nervous system | Information in and out |
Somatic nervous system | Voluntary skeletal muscles |
Autonomic nervous system | Involuntary glands smooth muscle cns and cardiac muscle |
Symethic | Motor commands sympathy engaged |
Parasympathetic | Relaxes you floaty |
Sensory neuron | Has information to cns affrent neuron |
Motor neuron | Effent neuron |
Inter- | Interacting neuron internerons brain and spinal cord |
Dendrites | Neuron makes neurons |
Axon | Where pass action message down release chemical message |
Multiple sclerosis | Destruction of myelin sheaths in cns by immune response myelin attack by person antibodies will not get contract will cause fatigue weakness stop atrophy mood problems numb limbs |
Neuroglia | Provide structure support for neuron said in formation of synapses |
Cns | Central nervous system |
Astrocytes | Connects neurons to blood vessels |
Ollgodendrocytes | Myelinate cns axons |
Microglia | Phagocytic cell provides structural support |
ependyma or enedymal cells | Line central canal spinal cord and ventricles of brain and spinal cord covers choroidpiexuses |
Depolarized | If membrane protentional becomes less negative more positive |
Hyperporized | Becoming more negative |
Vesicles trafficking | Tempture drops |
Opiate drugs | Morphine painkillers from poppy plant |
Endorphians | Human body produces opiates. Which can be addictive useful for server pain |
Antagonist | Drug that binds to receptor blocks neurontransmitter binding |
Agonist | Drug that activates receptor causing action potential or aiding in binding of neurotransmitter |
Amphetamines | Enhance noriephrine activity elevation alterness and mood |
Facial expression muscles | small and in the dermis paralysis causes sag found in scalp forehead around the eyes nose mouth and the neck |
Four major muscles | temporalis, masseter, lateral pterygoid, medial pterygoid |
TMJ Syndrome Temporomandibular joint | articulation problem between mandibular condyle of mandidble and mandibular fossa of temporal bone |
Pectoral girdle hip bone muscles | originate on axial skeleton and insert on to clavicle or scapula |
hamstring group | main function is to bend knees during walking running climbing stairs and jumping |
Quadriceps group | four separate muscles that fuse into one common tendon patella |
dendrites | receive input |
sensory receptors | at the end of neurons determined sensory integrative and motor |
somatic nervous system | voluntary communicaates to the central nervous system to skeletal muscles causing contraction |
autonomic nervous system | communicates instructions to the central nervous system that control viscera heart and various glands |
synaptic cleft | ends of neuron |
schwann cells | large axons of peripheral neurons in lipid rich sheaths |
multipolar neuron | many processes arising from it cell body |
ganglia | nervous tissue in a multipolar neuron |
bipolar neuron | has two processes from either end |
interneurons | in the brain and spinal cord rely on information |
unipolar neuron | cell body with a single process that divides into two branches and functions as a axon |
motor neuron | conducts impulses from the brain or spinal cord out the effects muscles or glands |
ependyma | cuboidal or columnar cells in shape and many have cilia |
satellite cells | small cuboidal cells that surround cell bodies of neurons in ganglia |
presynapic neuron | sender to the synapse muscle or glandular cell |
resting potential | not sending impulses |
membrane potential | potential difference across cell membrane |
action potential and threshold potential | neurons being depolarized -55 all or nothing response |
synaptic transmission | released neurotransmitter molecules diffuse across the synaptic cleft and bind to receptors on the post synaptic cell membrane |
neurotransmitters | neuron system produces 100 different types in the brain alone |
Acetylcholine | controls skeletal muscle actions |
norepinephrine` | creates a sense of well being low levels may lead to depression |
dopamine | creates a sense of well being deficiency in some brain areas associated with Parkinson disease |
serotonin | primarily inhibitory leads to sleepiness action is blocked by LSD enhanced by selective serotonin rep take inhibitor antidepressant drugs |
histamine | release in hypothalamus promotes alertness |
GABA | generally inhibitory |
Enkephalins | increase during periods of painful stress |
