Answer:
Most correct answer is all of the germ layers
Explanation:
Mucous membranes constitute the innermost layer of a number of hollow organs (i.e.: gastrointestinal tract). They are composed of an epithelial lining which overlies a deeper layer of connective tissue. Typically, each of these components arises from a different germ layer. For instance: the mucous lining of the gut arises from a combination of endoderm-derived epithelium and lateral mesoderm-derived connective tissue. Other mucous membranes may have different origins, for example: The mucous lining of the oral cavity is composed of ectoderm-derived epithelium and underlying connective tissue derived from head mesenchyme (combination of cephalic neural crest and paraxial mesoderm).
Summary:
Mucous Membrane = Epithelium (derived mainly from endoderm, followed by ectoderm, rarely mesoderm) + Underlying Connective Tissue (usually mesoderm)
Answer:
Stimulants are the best and most common type of medication used to treat ADHD. There are only two stimulant medications, methylphenidate (the active ingredient in Ritalin, Concerta and other formulations) and amphetamine (the active ingredient in Adderall, Vyvanse and other formulations).
The heart rate of the fetus in relation to the contractions is the priority consideration while caring for a mother who is having strong contractions one minute apart.
There are a number of point which have to be taken care of when a mother is having strong contractions which are 1 minute apart but the priority is always to check the status of the fetus. This is important because the blood flow of the placenta gets interrupted temporarily with every contraction and therefore if the contractions are too strong and too long lasting, the fetus might not able to tolerate them.

A penetrating abdominal injury with severe respiratory distress has most likely involved Diaphragm.
What is the penetrating abdominal injury ?
Penetrating stomach injuries to the thorax: a wound that enters above the costal border, below the fifth intercostal gap. These wounds have the potential to have started in the chest before moving through the diaphragm and into the abdomen.
What organ sustains damage the most frequently when the abdomen is penetrated?
The following organs are the most frequently injured in abdominal injuries caused by stab wounds: Liver (40%) Small intestine (30%) Diaphragm (20%)
Diaphragmatic injuries are quite uncommon and are brought on by either penetrating or blunt trauma. 1-7% of patients who sustain significant blunt trauma and 10-15% of patients who sustain penetrating trauma to the lower chest experience traumatic diaphragmatic rupture.
