Answer: Cervical canal
Explanation:
The process by which male gamete and female gamete fuse together to form a zygote is known as fertilization.
During sexual intercourse millions of sperms are released from penis that reaches the vagina and gets stored there temporarily. The sperm from vagina travels through the cervical canal to move into the uterine cavity.
From there it reaches the Fallopian tube. Hence, the correct answer is cervical canal.
Answer:
In 1864, while working at Glasgow University as Professor of Surgery, Lister was introduced to Pasteur's germ theory of disease, and he decided to apply it to the problem of surgical infections
Answer:
Arterial blood gas (ABG) results from a 68-year-old woman with difficulty breathing show:
- Oxygenation (PaO₂): hypoxemia
- pH: acidosis
- PaCO₂: Hypercapnia
- HCO₃⁻: normal
whose interpretation is: <u>respiratory acidosis</u>.
Hypercapnia can produce symptoms such as confusion, drowsiness or lethargy, headache, nausea and vomiting and, in severe states, can cause severe unconsciousness and coma.
Explanation:
Respiratory acidosis is due to a failure in the breathing process that produces <u>hypoventilation</u>, decreasing the partial pressure of oxygen (PaO₂) —hypoxemia— and increasing the partial pressure of CO₂ (PaCO₂), called hypercapnia.
- <u><em>Acidosis</em></u><em> is the result of the accumulation of CO₂ in the body, which is reflected as a decrease in </em><em>pH</em><em> below 7.35, with no change in bicarbonate content.</em>
- <u><em>Hypoxemia</em></u><em> is the decrease of PaO₂ below 60 mmHg.</em>
- <u><em>Hypercapnia</em></u><em> is the increase of PaCO₂ in ABG above 45 mmHg.</em>
- <em>Normal </em><em>bicarbonate</em><em> </em><em>(HCO₃⁻) </em><em>values range from 22 to 28 mEq/L in ABG. This compound can be altered in metabolic acidosis.</em>
<u>Hypercapnia mainly affects the nervous system</u>, producing symptoms that alter the state of consciousness of the affected, also producing headache and even nausea and vomiting.
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.
