Learning about the nervous system helps us know how messages that are sent to and from the brain cause ________
behavior
The nervous system controls:
- Emotions
- Movements
- Thinking
- Behavior
The nervous system is _____ __ ____
never at rest
Central Nervous System (CNS):
- Brain
- Spinal cord
Peripheral Nervous System (PNS):
Nerves branching beyond the spinal cord into the body
- Somatic Nervous System
- Autonomic Nervous System
Protection of brain:
skull and layers of sheathing
Protection of Spinal Cord:
vertebrae
Protection of Peripheral Nerves:
layers of sheathing
The long, thin cells of nerve tissue along which messages travel to and from the brain
Neurons
Basic Parts of the Neuron:
- Dendrites
- Cell Body
- Axon
- Axon Terminals
short, thin fibers that protrude from the cell body
Dendrites
Dendrites receive impulses, or messages from other _______ and send them to the cell body
neurons
contains the nucleus
Cell body
carries the impulses from the cell body toward the axon terminals
Axon
release neurotransmitters to stimulate dendrites of the next neuron
Axon terminals
the gap that exists between individual nerve cells or a junction between the neurons; less than one millionth of an inch wide
Synapse
the chemicals released by neurons, which determine the rate at which other neurons fire
Neurotransmitters
The part of the peripheral nervous system that controls voluntary movement of skeletal muscles
Somatic Nervous System (SNS)
The part of the peripheral nervous system that controls internal biological functions
Autonomic Nervous System (ANS)
prepares the body for dealing with emergencies or strenuous activity
Sympathetic nervous system
works to conserve energy and enhances body’s ability to recover from strenuous activity
Parasympathetic nervous system
The Brain is Composed of Three Parts:
- Hindbrain
- Midbrain
- Forebrain
A part of the brain located at the rear base of the skull that is involved in the basic processes of life
Hindbrain
Hindbrain:
- Pons
- Cerebellum
- Medulla
A small part of the brain above the pons that arouses the brain, integrates sensory information, and relays it upward
Midbrain
A part of the brain that covers the brain’s central core, responsible for sensory and motor control and the processing of thinking and language. The higher thinking processes (those that make us unique) are housed here
Forebrain
Forebrain:
- Thalamus
- Hypothalamus
- Cerebral Cortex
- Cerebrum
Regulates our emotions and motivations
Limbic System
Found in the core of the _________
forebrain
Limbic system composed of:
hypothalamus, amygdala, thalamus, and hippocampus
The different regions into which the cerebral cortex is divided:
- Occipital
- Parietal
- Temporal
- Frontal
- Visual signals are processed
- damage here causes visual problems including partial or total blindness
Occipital Lobe
Concerned with information from the senses all over the body
Parietal Lobe
Concerned with hearing, memory, emotion, speaking and advance visual processing
Temporal Lobe
Concerned with organization, planning, creative thinking and working memory (events that happened very recently)
Frontal Lobe
TOPIC
Left and Right Hemisphere
Left and right sides __________ each other
complement
Roughly ______ ______ of each other
mirror images
______ ________ carries messages back and forth between two hemispheres to jointly control human functions
Corpus callosum
Each hemisphere connected to one half of the body in a _____-_____ fashion
criss-cross
Left Hemisphere:
- Verbal
- Mathematical
- Analytical
Right Hemisphere:
- Nonverbal
- Spatial
- Holistic
speaking, understanding language, reading, writing
Verbal
analyzing separate pieces that make up a whole
Analytical
understanding simple sentences & words
Nonverbal
solving spatial problems such as geometry, enjoying
art
Spatial
combining parts that make up a whole
Holistic
TOPIC
Split Brain Operations
Corpus callosum is severed so no _____________ between hemispheres
communication
Lessons number and severity of grand mal ________
seizures
Intelligence, personality, and emotions remain practically _________
unchanged
Changes in ______________
verbalization
How Psychologists Study the Brain:
- Recordings
􀂄- EEG
- Stimulating
- Lesions
- Accidents
- Images
􀂄- CT scan
􀂄 - PET scan
􀂄 - MRI
90% of _______ are the result of narrowed arteries to the brain or blocked arteries causing severely reduced blood flow depriving brain cells of oxygen and nutrients. Cells begin to die within minutes
strokes
___________ _______ occur when a blood vessel in your brain leaks or ruptures (high blood pressure, weak spots in vessel walls)
Hemorrhagic strokes
Types of Dementia include:
- Alzheimer’s disease
- Lewy body dementia
- Vascular dementia
- Pick’s disease
- Reversible dementia
Damage to the brain as the result of injury
Traumatic Brain Injury
The second communication system for sending information to and from the brain is the _________ ______
endocrine system
In charge of body processes that happen slowly, such as ____ ______
cell growth
Works together with _______ ______ to help body function properly
nervous system
It is a chemical communication system, using ________, by which messages are sent through the ___________
hormones; bloodstream
The foundations of the endocrine system are the ________ and ______
hormones and glands
The Endocrine System is Instrumental in:
- Regulating mood
- Growth and development
- Tissue function
- Metabolism
- Sexual function and reproductive processes
Chemical substances that carry messages through the body in blood
Hormones
The hormones transfer information and instructions from one set of _____ to another
cells
Hormone levels can be influenced by factors such as:
- Stress
- Infection
- Changes in balance of fluid & minerals in blood
The Endocrine Glands:
- Pituitary Gland
- Thyroid Gland
- Adrenal Glands
- Sex Glands
- Pancreas
the center of control of the endocrine system
Pituitary Gland
secretes a large number of ________ many of which control the output of hormones by other endocrine glands
hormones

nutrients
Produces the hormone thyroxine that stimulates chemical reactions that are important to all tissues of the body
