Biological Psychology EPPP Flashcards
What is IV
Factor manipulated by experimentor
What is DV
Factor that is measured in response to manipulation
What is neuorplasticity
Ability for nervous system to change in response to environment
What is a neuron
basic unit of the nervous system
What are glial cells
non neural brain cells that provide structural, nutritional or other support
what is mitochandria
cellular organelle that provides metabolic energy
What are ribosomes
structures where genetic info is translate to produce proteins
4 zones of a neuron
input, integration, conduction, output
4 major parts of neuron
dendrites, cell body, axon, axon terminals
In which types of neurons is the cell body in the integration zone
Multipolar and bipolar
In which type of neuron is the dendritic branches in the integration zone
unipolar
What are multipolar neurons
Many dendrites, single axon
Which neuron is most common
multipolar neurons
what is bipolar neuron
single dendrite and single axon
Which neuron is associated with sensory, such as vision
bipolar neuron
what is a unipolar neuron
axon branches in two directions and transmit touch information from her body to the spinal cord
what is a motorneuron
neurons that govern movement that have long axons that reach out to synapse on muscles or organs
what is a sensory neuron
carries messages from the periphery to the spinal cord
what are interneurons
neurons that pass information from one neuron to the next, most neurons are this type
what is a synaptic vesicle
spherical vessel that contains neurotransmitters
what is the axon hillock
where the axon arises from, gathers and integrates information and processes information into electrical impulses
Are dendrites shorter than axons
typically yes
do dendrites have hillock-like region
no, on axons
is there myelin sheath on dendrites
no, on axons
