Neurons
They are responsible for identifying and chewing up substances that come into the brain that don’t belong there or cells that have died and need to be removed from the brain.
What is Microglia?
This is central to all behavior and mental processes.
What is CNS/Central Nervous System?
The covering insures faster neuron communication than without it.
What is myelin sheath?
Considered a scientific field founded by Franz Gall is now considered pseudo-psychology.
What is Phrenology?
These potentials result when either positively charged ion’s enter the cell.
What is Excitatory Post Synaptic Potentials (ESPS)?
These neurons have one axon and many dendrites, which allow them to communicate with other neurons
What are Multipolar Neuron/s?
Name and explain 2 types of brain plasticity?
What is functional plasticity (allows the brain to adapt when injured) and structural plasticity (change & adapt to experience/learning/active practice/environmental influences)?
Name the 2 factors that affect the speed of the action potential.
What is axon diameter (thicker axons are faster) & myelin sheath?
This is a part of the cerebrum. It sends electrical impulses to your muscles, in order to move them.
What is the Primary Motor Cortex?
This can affect moods or behavior, work by interfering with the normal functioning of neurotransmitters in the synapse.
What are MEDs/drugs?
This neuron sends signals to muscles.
What are motor neurons?
The neuron becomes positively charged during this process.
What is action potential?
Nancy's neural tube did not close caudally (towards the tail), this has resulted in this condition.
What is Spina Bifida?
This neurotransmitter is associated with Parkinson's disease.
What is dopamine?
One neuron communicates with another neuron
What is across the synaptic gap?
Name 2 things the Endochrine System is responsible for.
What are hormones, regulates physical processes & influence behavior, influence emotional & stress response, linked to CNS, chemically id to neurotransmitters?
This law states that once the action potential is activated it is always full size regardless of the strength of the stimulus.
What is the all-or-none law?
Name 4 functions of the brainstem.
What is Survival, Sleep/Wake Cycle, Sensory/Motor Function, Growth/hormonal behaviors?
They are involved in the transmission of physiological information from the body’s periphery such as communicating body temperature through the spinal cord up to the brain.
What are Unipolar neurons?
Its function is to support neurons by maintaining chemical balances in the brain, removing waste in the brain, and performing reparative functions in the brain.
What are Astrocytes?
Name 3 parts of the hindbrain that connects the spinal cord to the rest of the brain.
What are the medulla, the pons & the cerebellum?
During this process, the negative electrical charge of the axon's interior is -70 millivolts.
What is the resting potential?
The Peripheral Nervous System (PNS) is made up of 2 systems.
What is the somatic nervous system and the autonomic nervous system?
This particular neurotransmitter's primary role is to help in pain and positive emotions.
What are endorphins?
