Neurons |
The basic building blocks of the nervous system also known as a nerve cells |
|
|
The axon |
The middle process it passes a message through the terminal branches it can be several feet long |
|
|
dendrite |
Is where it all begins to receive the information and conducts it towards the cell body |
|
|
Glial cells |
They support nourish and protect the neurons we have 9 times more glial cells and neurons they create myelin sheath and clean up |
|
|
neural impulse |
A brief electrical charge travels from 2 to 180 miles per hour it makes quick calculated decisions |
|
|
Neurotransmitters |
Neurons will only receive the ones that fit perfectly onto dendrite they cross the synapse gaps in one out of ten thousands of a second and it binds to receptor sites on the receiving neuron |
|
|
Reuptake |
The sending neuron reabsorbs the Nerotransmitters from the synapse |
|
|
Some neurotransmitters |
Dopamine Serotine Acetylcholine |
|
|
Endorphins |
Pain control and pleasure example heroin |
|
|
nervous system |
the body's speedy electrochemical communication network it consists of all the nerve cells on the peripheral of central nervous system |
|
|
, the central nervous system |
The brain and spinal cord |
|
|
Peripheral nervous system |
Sensory and motor neurons that connect the central nervous system to the rest of the body |
|
|
Nerves |
They're bundled acts on that form neutral cables connected to the central nervous system with muscles glands and sense organs |
|
|
Sensory neurons |
Neurons that carry incoming information from the sensory receptors to the brain and spinal cord |
|
|
Motor neurons |
neurons that carry out going information from the brain and spinal cord to the muscles and glands |
|
|
Interneurons |
It is in between brain and spinal cord it communicates between the sensory inputs and motor outputs |
|
|
Biological psychologist |
Studies the links between our biology and behavior |
|
|
synapse |
The space between the terminal of the neuron to the other neuron weather neurotransmitters are released |
|
|
Myelin sheath |
reproducing up to 25 years of age not all axons have it it's a layer of fatty tissue that insulates and speeds the impulses it affects judgment and self control |
|
|
Hormones |
Chemicals created by the endocrine glands that travel through bloodstream and the impact tissue |
|
|
Adrenal glands |
Endocrine glands secret to hormone epinephrine and norepinephrine |
|
|
Pituary gland |
Located in the core of the brain responsible for growth development it produces oxytocin which causes orgasm breast milk and is the master gland controlled by the hypothalamus |
|
|
The brain |
Composed of two identical hemispheres The most complex organ damage to one side can affect the other |
|
|
The brain stem |
It is the oldest parts of the brain responsible for automatic survival functions such as breathing there's two parts the medulla and ponds |
|
|
The medulla |
It is the base control heartbeat and breathing |
|
|
pons |
Coordinates movement |
|
|
The thalamus |
Is responsible for touch sight hearing taste it processes information it is also responsible for arousal |
|
|
The cerebellum |
Processing sensory input coordination balance and voluntary movement it allows us to tell time in motion and distinguish sounds |
|
|
Limbic system |
One of the newest part of the brains 1) hypothalamus bodily maintenance such as hunger thirst body temperature sexual behavior it keeps homeostasis 2) hippocampus processes conscious memories 3) amygdala deals with aggression and fear |
|
|
Cerebral cortex |
It is 85% of the brain it is the newest part of the brain it is more than double perceives thinking and speaking |
|
|
Motor cortex |
Controls voluntary movement |
|
|
Sensory cortex |
Processes information touch and movement |
|
|
Frontal lobe |
Speaking judgement muscle movement making plans and personality |
|
|
Peripheral lobe |
Touch and body position |
|
|
Occipital lobe |
Visual information |
|
|
Temporal lobe |
Auditory information |
|
|
Plasticity |
The ability for the brain to change adapt and grow develop in life |
|
|
Neurogenesis |
Formation of new neurons |
|
|
Corpus callosum |
Band of neural fibers that connect left and right |
|
|
, left side of the brain |
Responsible for language |
|
|
Right side of the brain |
Responsible for creating meaning and sense of language and self-awareness |
|
|
Chromosomes |
43 threadlike structures 23 from mom 23 from dad |
|
|
DNA |
make up chromosomes make up every single cell |
