NERVOUS SYSTEM - HILARY TARIGAN P.5
REFLEX ARC
3. INTERNEURONS INTERGRATE & PROCESS INFORMATION
4.MOTOR NEURON TRANSMITS TOWARDS EFFECTOR
2. NERVE IMPULSE TRAVELS --> CNS
5. EFFECTOR RESPONDS TO NERVE IMPULSE
1. RECEPTORS
MAJOR DIVISIONS & SUBDIVISIONS of NERVOUS SYSTEM
PERIPHERAL NERVOUS SYSTEM
SENSORY (SA)
carry info from nerves to CNS
MOTOR (ME)
away from cns
ANS:
INVOLUNTARY
,
cardiac, smooth
SYMPATHETIC:
Responsible for
FIGHT or FLIGHT
THORACOLUMBAR
PARASYMPATHETIC:
Calms
the system down **CRANIO
SNS:
VOLUNTARY
,
impulse
from
CNS --> SKELETAL
CENTRAL NERVOUS SYSTEM:
spinal cord and brain
MAJOR PARTS AND FUNCTIONS OF THE
SPINAL CORD
FUNCTION:
Provides a
TWO-WAY
connection to and from the
BRAIN & BODY
PROTECTED
by
bone, meninges, and CSF
TWO lengh ways
that connect and send impulses
DORSAL ROOT
VENTRAL ROOT
NEUROTRANSMITTERS
COMPARE/CONTRAST A.N.S
MAJOR FUNCTIONS
1. SENSORY INPUT:
Sensory receptors gather all information that is being inputted by the internal and external changes
CONTROLS
and
COMMUNICATE
the systems in the body
3. MOTOR INPUT:
Activation of
EFFECTOR
organs
(muscles & glands)
produces a response.
2. INTEGRATIONS:
Processes and interprets sensory inputs.
SPINAL NERVES
TISSUES (Structure & function of neurons and neuroglia)
MYELIN SHEATH
PERYKIRANON (SOMA)
AXON TERMINAL
SNYAPSE
DENDRITES
MAJORS PARTS AND FUNCTIONS OF THE
BRAIN
DIENCEPHALON
EPITHALAMUS: contains pineal gland,
secretes
melatonin
HYPOTHALAMUS: In charge of hunger and thirst
THALAMUS: Helps with sensory receptors
BRAIN STEM:
helps with the heart and breathing cycles
PONS: sleep and arousal
MEDUALLA OBLONGTA: helps with blood pressure
MIDBRAIN
SPINAL CORD
LOBES
PARIETAL: TOUCH
OCCIPITAL: VISUALS
FRONTAL: DECISION
TEMPORAL: AUDITORY
CEREBELLUM:
Helps with balance and coodination

OLIGONDROCYTES
ASTROCYTES
CRANIAL NERVES
VI. ABDUCENS: MOVES EYEBALL
VII. FACIAL: SMILING MOVEMENTS
V. TRIGEMINAL: JAW AND FACE MOVEMENT
VIII. VESTIBULOCOCHLEAR: LOCATE SOUNDS
III. OCULOMOTOR: EYE MOVEMENTS (DILATION)
IX. GLOSSOPHARYNGEAL:
TASTE
(THROAT)
IV - TROCHLEAR: LOCATING SOUNDS
X. VAGUS:
TASTE
(MOUTH)
XI. ACCESSORY: SPINAL MUSCLE MOVEMENTS (RESISTANCE)
II - OPTIC: Nerve for
SEEING
I - OLFACTORY: Nerve for
SMELLING
XII. HYPOGLOSSAL: TONGUE
CT COVERINGS
ARACHNOID MATER
PIA MATER
DURA MATER
DISORDERS/ DISEASES
AUTISM:
can be hereditary
MENINGITIS:
BLEEDING IN THE MENINGES
SPINAL CORD INJURY:
Damage to the spinal cord that could lead to paralysis, weakness, and spastic muscles
ALZHEIMER'S DISEASE
Loss of memory, a form of dementia
CEREBROVASCULAR ACCIDENT (STROKE)
Lack of blood flow to the brain
MULTIPLE SCLEROSIS:
an autoimmune disease that affects the myelin sheath
hereditary, and causes muscle weakness

1. RESTING STATE
MOUSE PARTY DRUG ABUSE
MARIJUANA
INTERFERES
with
INHIBITORY
THC
mimics and blocks*
cannabinoid
receptors --> causes inhibition to turn off and dopamine is released into the synapse.
Affects movements, memory, and relaxation
ALCHOHAL
Interacts with GABA receptors --> more inhibitory, binds with glutamate receptors preventing glutamate from exciting
affects memory, decision making, and impulse control
INTERFERES
with
INHIBITORS & GLUTAMATE
COCAINE
BLOCKS
dopamine transporters, traps dopamine in the synaptic cleft
affects
voluntary movements:
fidgety & unable to be still
INTERFERES
with
DOPAMINE
ECSTACY
MIMICS
serotonin, floods receptors,
TRANSPORTS
serotonin and leaves serotonin hormones floating in the synaptic cleft
Affects mood, sleep, perception, and appetite
STIMULATES
release of dopamime
INTERFERES
with
SEROTONIN
LSD
mimics serotonin & binds to serotonin receptors,
affects feelings of wakefulness & a response to random stimuli
INTERFERES
with
SEROTONIN
METHAMPHETAMINE
MIMICS
dopamine, goes through transporters,
HIGHLY
ADDICTIVE
,
intense pleasure
and
exhilaration
INTERFERES
with
*DOPAMINE
HEROIN
Binds
to
opiate
receptors --> causes
increase in dopamine
Natural painkiller, calm and less stressed mood
INTERFERES
with
DOPAMINE NEUROTRANSMITTERS
