The Nervous System
The nervous system is the electrochemical information network.
The Peripheral Nervous System (PNS) links the nervous system with the sense
receptors, muscles and glands.
Nerves are the axons which carry the PNS information
The Central Nervous System
The spinal cord connects the PNS to the brain
Ascending neural fibers send up sensory information while descending fibers send
down motor control information.
Reflexes are a simple, automatic response to sensory stimuli. (lik
The autonomic nervous system contains adrenal glands which release epinephrine and
nor-epinephrine. It is located on the top of the kidneys and provides us with energy by
increasing the heart rate, blood pressure and sugar.
The pituitary gland is locate
The proportion of glial and nerve cells are higher in more complex animals
Each brain hemisphere is divided into four lobes, separated by fissures (folds), the lobes
include the frontal lobe, parietal lobe, occipital lobe and the temporal lobe.
Neurotransmitters are chemical messengers that extend across the synaptic gaps
between the neurons. When released by the sending neuron, neurotransmitters travel
across the synapse and binds to receptor sites on the receiving neuron, showing that it
Each neuron has a cell body and branching fibers.
The neuron is a nerve cell, which is the basic foundation of the nervous system.
Dendrites are the bushy, branchy extensions of a neuron that receives messages and
Aphasia- impaired use of language, some people cannot read due to the damage to critical areas
Brocas area- area of the frontal lobe. Damage causes someone not to be able to speak words
Wernickes area- controls language reception. Da
1. Once a neuron fires, the axon will be open to positively charged sodium ions
2. The axon is then depolarized. The next part of the axon will open, leading other parts
of the axon to open as well. (chain reaction)
3. The Refractory period is also known
