Which synapse(s) are specifically responsible for the habituation of the withdrawal response?
fredd [130]

<u>Sensory neuron to motor neuron</u> are specifically responsible for the habituation of the withdrawal response.

  • The withdrawal reflex, which is the automatic withholding of a limb from a painful stimulation, is what is known as this automatic reaction.
  • Humans are shielded by this reflex from tissue necrosis brought on by exposure to noxious stimuli like pain or heat. Either the upper or lower limbs may experience it.
  • A somatic reflex, like the withdrawal reflex, and a visceral reflex, an autonomic reflex, differ in that the latter has an efferent branch.
  • The lower motor neuron in the ventral horn of the spinal cord, which immediately projects to a skeletal muscle to produce its contraction, is the output of a somatic reflex.

1. A normal mammalian cell will shrink if it is placed into_________. (Assume all solutes are non-penetrating) A. pure water B.
GrogVix [38]

Answer:

B. 50 mM glucose; E. 300 mM glucose

Explanation:

In order for the cell to shrink the concentration of solutes in the blood should be above normal or higher than the intracellular concentration, so that water moves from the inside of the cell to the outside by the process known as osmosis.

The normal blood levels of NaCl = ~ 154 mM; therefore A, C and D will not cause any shrinkage.

The normal blood levels of glucose = ~ 3.9 to 7.1 mM; therefore water would move from the intracellular to the extracellular space since the solutes are 10x higher outside the cell, causing shrinkage of the cell.
