Explanation:

Peristaltic movement is responsible for pushing the fecal matter from the sigmoid colon to the rectum . This results in the distension in the rectum by which the stretch receptors are stimulated .

The information is carried by the sensory neuron from the receptors to the spinal cord and the motor nerve bring information from the cord to the descending colon then to the sigmoid colon and then rectum, and finally to anus , which results in the contraction of longitudinal rectal muscles which decreases the rectum and thereby the pressure increases within the rectum leading to opening of internal sphincter .

Whete does the stimulus occur in order to initiate an AP?
amid [387]

Answer:

The answer to the question: Where does the stimulus occur in order to initiate an AP, would be, B: Dendrites.

Explanation:

When an impulse is to be generated and passed on as an action potential towards a corresponding neuronal cell, and a final affected organ, the neurons need first to be stimulated so that an action potential begins. This stimulus comes as a neurotransmitter released by other neurons near the one that will be stimulated. This neurotransmitter will bind to the receptors on the dendrites of the neuron to be stimulated and immediately this will cause the ion channels, gated and non-gated, to open and close so that an action potential can be initiated. The cell body then initiates the first action potential, and will in turn stimulate the axon to also start their own action potential, which will, like a domino effect, move down to the axon terminals. This process will be followed all along a neuronal circuit.

An IV bag of 500 mL solution is started at 1900. The flow rate is 38 gtts per minute, and the drop factor is 10 gtts per mL. At
Ronch [10]

Answer: your bag will finish at 2112.

Explanation: (38gtt/min) × (10gtt/ml).

Cross multiply. (38gtt×1ml) × (1min×10gtt)

This gives you 38/10...and the gtts cancel out so, it's 38ml/10min.

Simplify this to 3.8 ml/min.

Now, 3.8ml/x min = 500 ml.

Take 500/3.8. This gives you about 132 minutes if you round to the nearest minute. 60 min/he means 132 min = 2h12m. 2h12m from 1900 is 2112.
