5 Multiple Choice Questions
- A specialized endoplasmic reticulum that regulates the calcium concentration in the cytosol of muscle cells
- The regulatory protein that blocks the myosin-binding sites on actin molecules
- A gated channel for a specific ion. The opening or closing of such a channels may alter a cell's membrane potential.
- An extension of the hypothalamus composed of nervous tissue that secretes oxytocin and antidiuretic hormone made in the hypothalamus, temporary storage site for these hormones.
- The short time immediately after an action potential in which the neuron cannot respond to another stimulus, owing to the inactivation of voltage-gated sodium channels
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.
Nodes of Ranvier → A gated channel for a specific ion. The opening or closing of such a channels may alter a cell's membrane potential.
Complete Proteins → ...
Nontropic Hormones → A hormone that has an endocrine gland or cells as a target.
Graded Potential → In a neuron, a shift in the membrane potential that has an amplitude proportional to signal strength and that decays as it spreads.
