Answer:
The correct answer is option B ( ligand gated channels opened by neurotransmitter molecules).
Explanation:
Input region or postsynaptic region or dendrite is the site of neuron cell which receives the impulse from the pre-synaptic neuron at the synaptic junction.
The cell membrane of the dendrite is embedded with ligand-gated channels which opens up in response to the ligand (neurotransmitters) produced by the neurotransmitter vesicle of axon or output region of neuron.
The neuromuscular junction is such a case where acetylcholine receptors present in the dendrite opens in the presence of acetylcholine.
Thus, option B ( ligand-gated channels opened by neurotransmitter molecules) is the correct option.
Answer:
Homeostasis is the state of steady internal, physical, and chemical conditions maintained by living systems
Explanation:
(A property of cells, tissues, and organisms that allows the maintenance and regulation of the stability and constancy needed to function properly)
The uterus, specifically the Fallopian tube.
The priority after administering is to assess fetal heart
rate. After administering an opioid to a laboring mother, the main concern is
to evaluate the effect on the fetus. Opioid administration can cross the
placental obstruction with signs as well as measuring heart rate and
variability. Subsequently after birth, there may be a reduction in attentiveness.
Maternal factors of a reduced blood pressure, constipation and dry month are of
a lesser importance.
