5 Matching questions

  1. Nontropic Hormones
  2. Central Nervous System (CNS)
  3. Parasympathetic Division
  4. Cephalization
  5. IPSP (Inhibitory post-synaptic potential)
  1. a One of the three divisions of the autonomic nervous system, generally enhances body activities that gain and conserve energy, such as digestion and reduced heart-rate, decrease breathing, storing glycogen for energy in the liver
  2. b The portion of the nervous system where signal integration occurs; in vertebrate animals, the brain and spinal cord
  3. c An evolutionary trend toward the concentration of sensory equipment at the anterior end of the body.
  4. d 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
  5. e ...

5 Multiple choice questions

  1. ...
  2. In a neuron, a shift in the membrane potential that has an amplitude proportional to signal strength and that decays as it spreads.
  3. 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
  4. The metabolic rate of a resting, fasting and non stressed endotherm at a comfortable temperature.
  5. The fundamental, repeating unit of striated muscle, delimited by the Z lines

5 True/False questions

  1. MyosinA type of motor protein that associates into filaments that interact with actin filaments to cause cell contraction

          

  2. Peripheral Nervous System (PNS)The portion of the nervous system where signal integration occurs; in vertebrate animals, the brain and spinal cord

          

  3. TropomyosinThe regulatory protein that blocks the myosin-binding sites on actin molecules

          

  4. HypothalamusAn 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.

          

  5. SynapseA specialized center of body function composed of several different types of tissues
