- IPSP (Inhibitory post-synaptic potential)
- Interstitial Fluid
- a A longitudinal bundle in a muscle cell (fiber) that contains thin filaments of actin and regulatory proteins and thick filaments of myosin
- b 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
- c The fluid filling the spaces between cells in most animals
- d An organism that is warmed by heat generated by their own metabolism, Heat usually maintains a relatively stable body temperature higher than that of the external environment.
- e The regulatory protein that control the position of tropomyosin on the thin filament.
5 Multiple choice questions
- 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.
- In a neuron, a shift in the membrane potential that has an amplitude proportional to signal strength and that decays as it spreads.
- The total amount of energy an animal uses in a unit of time.
- An integrated group of cells with a common structure, function or both
5 True/False questions
Myelinated Sheath → Wrapped around the axon of a neuron, an insulating coat of cell membranes from Schwann cells or oligodendrocytes. It is interrupted by nodes of Ranvier, where action potentials are generated
Basal Metabolic Rate (BMR) → The metabolic rate of a resting, fasting and non stressed endotherm at a comfortable temperature.
Cephalization → An evolutionary trend toward the concentration of sensory equipment at the anterior end of the body.
Refractory Period → An organism for which external sources provide most of the heat for temperature regulation.
Threshold → The potential that an excitable cell membrane must reach for an action potential to be initiated
