- IPSP (Inhibitory post-synaptic potential)
- a An organism for which external sources provide most of the heat for temperature regulation.
- b The ventral part of the vertebrate forebrain; functions in maintaining homeostasis, especially in coordinating the endocrine and nervous systems; secretes hormones of the posterior pituitary and releasing factors that regulate the anterior pituitary
- c An electrical change (usually hyperpolarization) in the membrane of a post-synaptic neuron caused by the binding of an inhibitory neurotransmitter from a presynaptic cell to a post synaptic receptor; makes it more difficult for a post-synaptic neuron to generate an action potential
- d .Muscle in which the regular arrangement of filaments creates a pattern of light and dark bands
- e The fundamental, repeating unit of striated muscle, delimited by the Z lines
5 Multiple choice questions
- A gated channel for a specific ion. The opening or closing of such a channels may alter a cell's membrane potential.
- The potential that an excitable cell membrane must reach for an action potential to be initiated
- The fluid filling the spaces between cells in most animals
5 True/False questions
EPSP (Exitatory post-synaptic potential) → An electrical change (depolarization) in the membrane of a post-synaptic cell caused by the binding of an excitatory neurotransmitter from a presynaptic cell to a post-synaptic cell; makes it more likely for a post-synaptic cell to generate an action potential.
Epithelial Tissue → Animal tissue that functions mainly to bind and support other tissues, having a sparse population of cells scattered through an extracellular matrix
Cephalization → A change in a cell's membrane potential such that the inside of the membrane is made less negative relative to the outside. For example, a neuron membrane is depolarized if a stimulus decreases its voltage from the resting potential of -70 mV in the direction of zero voltage.
Temporal Summation → A phenomenon of neural integration in which the membrane potential of the post-synaptic cell is determined by the combined effect of EPSPs or IPSPs produced nearly simultaneously by different synapses.
Motor Division → One of the three divisions of the autonomic nervous system; consists of networks of neurons in the digestive tract, pancreas, and gall bladder; normally regulated by the sympathetic and parasympathetic divisions of the autonomic nervous system. (secretions + peristalsis can function independently from parasympathetic and sympathetic but can also be affected by it)
