Please, can you understand and explain it to me?

Don't forget to read the instructions when you buy a pregnancy test, the instructions are more accurate and clearer. The pregnancy test stick achieves the function of pregnancy test through such a principle, that is, once the human chorionic gonadotropin in the blood is HCG positive, the blood positive will be excreted through the urine, and the hcg positive pregnancy test stick in the urine will show two bars. When using the pregnancy test stick, you should read the instructions, and keep a reasonable urine sample, which should not be too little or too much, not too concentrated or too diluted.

For example, the urine excreted after drinking 2 catties of water will be very clear, the hCG of the urine may be diluted, and the pregnancy test stick will show a false negative, which is negative but not negative; The urine is very concentrated, and there is basically no urine in the morning, and the urine that is very yellow and very concentrated may not be particularly accurate when measured with HCG test strips. I hope you leave a suitable time period and an appropriate amount of urine, put the pregnancy test stick in it according to the specified time, wait 5 minutes and take it out to see if it is two bars or one bar.

This is pregnant, one bar is normal, two bars are pregnant, it is recommended to go to the hospital for a checkup!

If you are currently in the first trimester of pregnancy and are showing signs of pregnancy, you can go to the hospital for a test.

Congratulations, congratulations, this is the rhythm of being a mom or a dad! Go to the hospital for a check-up.

Pregnant! Pregnant! Pregnant! Pregnant!

Yes, although it is a little light, it is recommended that it will not be light in the next morning.

Han Li's is great.

There are two lines of pregnancy test sticks, one of which is darker in color, which is called the quality control line, which means that there is no problem with the quality of this pregnancy test stick; If the thread is missing or the thread is lighter, the pregnancy test is invalid.

The other line is the test line, turning red means that you are very likely to be pregnant, if there is also menopause, you can basically confirm the pregnancy. A lighter color indicates that there is relatively little chorionic gonadotropin in the urine.

It is recommended to go to the hospital for a blood test of chorionic gonadotropin, and if the chorionic gonadotropin in the blood is positive, the diagnosis of pregnancy can be confirmed.

n tends to be poor and large, then 1 n, 1 n, and 4 n all tend to be 0, so the numerator limit is 2+0=2, and the denominator limit is 1+0+0=1, so the result is 2

The trochlear nerve is the fourth cranial nerve. The trochlear nerve is a motor nerve, which originates from the nucleus of the trochlear nerve on the opposite side of the hypothalamus of the midbrain, and exits from the dorsal hypothalamus of the midbrain. After emanating from the brain, it goes forward around the lateral side of the cerebral foot, passes anteriorly through the lateral wall of the cavernous sinus, enters the orbit through the supraorbital fissure, crosses the superior rectus muscle and levator palpebrae superioris and travels anteriorly medially, enters and innervates the superior oblique muscle. The trochlear nerve is the thinnest of the cranial nerves.

When contracted, the eyeball is pulled so that the pupil turns outward and downward. The superior oblique muscle acts in response to the superior rectus muscle, and both contract at the same time, so that the pupil is facing forward. Innervated by trochlear nerve.

This muscle, the thinner and longest of the extraocular muscles, originates on the Zinn's common eyeliary ring above the optic nerve foramen. This part covers the beginning of the levator palpebrae superioris muscle. The shorter tendon that emerges after issuance is a fusiform muscular abdomen that travels between the orbital roof and the inner wall of the orbit to reach the trochlea.

At about 10 mm from the trochlea, the abdomen evolves into a tendon, passes through the trochlea, turns and extends posteriorly and laterally, at an angle of about 55° to the axis of opreservation, passes under the superior rectus muscle, and attaches to the outer upper quadrant of the posterior eyeball in a fan-shape, the total length of the muscle is about 62 mm, and the tendon is about 30 mm long. The attachment point is approximate. Superior oblique muscle abdomen is orbital roof; The inferior part is the medial rectus muscle, and there are ophthalmic arteries, anterior and posterior ethmoid arteries, and nasal nerves passing through the medial rectus muscle.

From posterior to anterior between this muscle and the levator palpebrae superioris muscle, there are trochlear nerves, supratrochlear nerves, frontal arteries, and supraocular vein branches. Above the reflex tendon are the supratrochlear nerve, the medial branch of the supraorbital nerve, and the supraorbital vessels. There are superior rectus muscles, levator palpebrae superioris above the fan-shaped aponeurosis, and the lower part is the eyeball, and the reflex tendon of this muscle is at an angle of 55° to the axis of optic eyes, so its main function is to turn the eyeball downward, and some scholars believe that it is internal rotation, followed by abduction and internal rotation.
