Give an example of a peripheral effector
muscles, glands
Location where signal is passed across a synapse to other cells
Axon terminal
What is myelin mostly made of?
Lipids (fats)
An electrical impulse, traveling along a neuron that enables communication between nerves, muscles, or glands, is also known as an
Action Potential
Brain waves are measured by an...
EEG (Electroencephalogram)
Beta Waves
Rest, meditation, relaxation (type of brain wave)
Alpha Waves
Off task, daydreaming (type of brain wave)
Theta Waves
Sleep (Slow wave sleep) (type of brain wave)
Delta Waves
Identify three parts of a neuron
Cell body (soma), dendrites, axons, myelin sheaths, nodes, etc.
Consolidation of the central nervous system’s structures, functions, and activities
Cephalization
The brain's relay station, processes and directs sensory and motor signals
Thalamus
Connect sensory and motor neurons within the CNS, facilitating communication and reflexes
Interneurons
These cells create cerebrospinal fluid
Glia
Resting membrane potential
-70 mV
The more ___ the neuron is, the more likely it is to fire.
positive
If chromatin is ___, then the DNA can be expressed.
loose
This network, involving structures such as the prefrontal cortex and amygdala, is responsible for regulating emotional responses and decision-making.
Limbic system
Schwann cells, in the PNS, form an insulating material around axons that speeding up nerve impulses. Similarly, oligodendrocytes, in the CNS, have the same function. What type of cells are Schwann cells and oligodendrocytes?
Glial cells
Identify three specific effectors within the brain.
Hypothalamus, pituitary gland, amygdala, pineal gland, etc.
Astrocytes support neurons, regulate blood flow, and balance ion levels, among other functions. What type of cell is an astrocyte?
Glial cell
This phenomenon, where the brain's neural networks adapt and reorganize in response to injury or learning, is essential for cognitive recovery and skill acquisition.
Neuroplasticity
What is the critical period in brain development?
The critical period in brain development, where the brain is particularly sensitive to environmental stimuli and experiences, can significantly influence cognitive and emotional outcomes later in life.
What is neurogenesis? (hint: break down the term)
This process, involving the formation of new neurons from neural stem cells, primarily occurs in the hippocampus and is crucial for learning and memory.
This process involves the fusion of synaptic vesicles with the presynaptic membrane to release neurotransmitters into the synaptic cleft.
Exocytosis
