What is a human tooth made out of?

45 answers

A human tooth is made up of several layers, each composed of different materials:

  1. Enamel: The outermost layer of a tooth, enamel is the hardest substance in the human body and is primarily composed of hydroxyapatite, a crystalline structure of calcium phosphate. Enamel protects the tooth from decay and physical damage.

  2. Dentin: Beneath the enamel is dentin, which makes up the bulk of the tooth. Dentin is less hard than enamel and is composed of mineralized tissue, primarily hydroxyapatite and a protein matrix, primarily collagen. Dentin contains microscopic tubules that can transmit sensations.

  3. Pulp: At the center of the tooth is the pulp, which contains nerves, blood vessels, and connective tissue. The pulp provides nourishment to the tooth and is critical for its health.

  4. Cementum: This is a bone-like substance that covers the root of the tooth, helping to anchor it in the jawbone. Cementum is also part of the periodontal ligament, which connects the tooth to the surrounding bone.

Together, these components contribute to the overall structure, strength, and function of a human tooth.

Today is November 9th, how many days was it 128 days ago (not Nov 9th it’s nov 15th just wondering)

To find the date that was 128 days before November 9, you can subtract 128 days from that date.

  1. November has 30 days. From November 9, there are 21 days left in the month (30 - 9 = 21).
  2. Subtract those 21 days from 128: 128 - 21 = 107 days remaining to account for.
  3. October has 31 days. Subtract 31 days for October, leaving you with: 107 - 31 = 76 days remaining to account for.
  4. September has 30 days. Subtract 30 days for September: 76 - 30 = 46 days remaining to account for.
  5. August has 31 days. Subtract 31 days for August: 46 - 31 = 15 days remaining to account for.
  6. Therefore, you would be at the end of July, and you need to count back 15 days into July.

So, 15 days prior to July 31 is July 16.

Adding it all up, 128 days before November 9 is July 16.

Today is march 22nd what day was it 220 days afo

To find out what date it was 220 days before March 22, you can subtract those days step by step, considering the number of days in each month.

  1. March: March has 31 days. From March 22, there are 9 days left in the month (31 - 22 = 9).

    • Days remaining to account for: 220 - 9 = 211 days.
  2. February: For a non-leap year, February has 28 days.

    • Subtract 28 days: 211 - 28 = 183 days remaining.
  3. January: January has 31 days.

    • Subtract 31 days: 183 - 31 = 152 days remaining.
  4. December: December has 31 days.

    • Subtract 31 days: 152 - 31 = 121 days remaining.
  5. November: November has 30 days.

    • Subtract 30 days: 121 - 30 = 91 days remaining.
  6. October: October has 31 days.

    • Subtract 31 days: 91 - 31 = 60 days remaining.
  7. September: September has 30 days.

    • Subtract 30 days: 60 - 30 = 30 days remaining.
  8. August: August has 31 days.

    • Subtract 30 days (we only need to go 30 days back): 30 - 30 = 0 days remaining.

So, 220 days before March 22 was August 22.

104 days ago from march 22nd was..

To find out what date it was 104 days before March 22, you can subtract those days step by step, considering the number of days in each month.

  1. March: March has 31 days. From March 22, there are 9 days left in the month (31 - 22 = 9).

    • Days remaining to account for: 104 - 9 = 95 days.
  2. February: For a non-leap year, February has 28 days.

    • Subtract 28 days: 95 - 28 = 67 days remaining.
  3. January: January has 31 days.

    • Subtract 31 days: 67 - 31 = 36 days remaining.
  4. December: December has 31 days.

    • Subtract 31 days: 36 - 31 = 5 days remaining.
  5. November: Since you have 5 days remaining, you go back into November.

    • The date will be November 30 - 5 = November 25.

So, 104 days before March 22 was November 25 of the previous year.

94 days from march 22nd is..

To calculate the date that is 94 days after March 22, you can add the days month by month as follows:

  1. March: There are 31 days in March. From March 22, there are 9 days left in the month (31 - 22 = 9 days).

    • Days remaining to account for: 94 - 9 = 85 days.
  2. April: April has 30 days.

    • Subtract 30 days: 85 - 30 = 55 days remaining.
  3. May: May has 31 days.

    • Subtract 31 days: 55 - 31 = 24 days remaining.
  4. June: Now, you will have 24 days remaining in June.

    • Add 24 days to June 1 gives you June 24.

Therefore, 94 days after March 22 is June 24.

94 days ago from march 22nd was..

To calculate the date that was 94 days before March 22, you can subtract the days month by month:

  1. March: From March 22, there are 22 days in March (including March 1) if you count back to the beginning of the month.

    • Since you need to subtract 94 days, start by subtracting the 22 days in March.
    • Remaining days to account for: 94 - 22 = 72 days.
  2. February: February has 28 days (assuming it's not a leap year).

    • Subtract 28 days: 72 - 28 = 44 days remaining.
  3. January: January has 31 days.

    • Subtract 31 days: 44 - 31 = 13 days remaining.
  4. December: Now you are in December, and you need to go back 13 more days from December 31.

    • December 31 minus 13 days gives you December 18.

Therefore, 94 days before March 22 was December 18 of the previous year.

Hey how does a woman get pregnant? Just asking

Pregnancy typically occurs when a sperm fertilizes an egg. Here’s a general overview of the process:

  1. Ovulation: Each month, a woman's ovaries release an egg (ovum) during a process called ovulation. This usually occurs about midway through the menstrual cycle.

  2. Fertilization: For pregnancy to occur, sperm must be introduced to the woman's reproductive system. This typically happens through sexual intercourse, where sperm is ejaculated into the vagina. Sperm can then swim through the cervix and into the uterus to reach the fallopian tubes, where fertilization can occur if an egg is present.

  3. Implantation: If a sperm successfully fertilizes the egg, it forms a zygote, which begins to divide and develop as it travels down the fallopian tube toward the uterus. About 5-7 days after fertilization, this developing embryo (now called a blastocyst) will implant itself into the lining of the uterus, where it can grow and develop further.

  4. Development: Once implanted, the body begins producing hormones that support the pregnancy. The embryo develops into a fetus over the course of about nine months until childbirth.

If there are specific aspects of this process you’d like to know more about, feel free to ask!

So where does sperm come from

Sperm is produced in the male reproductive system. Here’s a brief overview of how it works:

  1. Testes: Sperm is formed in the testes, which are two small organs located in the scrotum. The testes produce sperm through a process called spermatogenesis. This process begins during puberty and continues throughout most of a man's life.

  2. Epididymis: Once sperm is produced in the testes, it matures and is stored in a coiled tube called the epididymis, which is located at the back of each testis.

  3. Vas Deferens: During ejaculation, sperm travel from the epididymis through the vas deferens, a muscular tube that connects the epididymis to the ejaculatory duct.

  4. Seminal Vesicles and Prostate Gland: As sperm move through the reproductive tract, they mix with fluids from the seminal vesicles and prostate gland. These fluids provide nourishment and help form semen, which is the fluid that is ejaculated during orgasm.

  5. Ejaculation: Finally, during sexual arousal, sperm is ejected from the penis into the vagina, which can lead to fertilization if it meets an egg.

If you have more questions about reproduction or any related topics, feel free to ask!

So it’s only through a male right

Yes, sperm is produced only in the male reproductive system. In the typical biological model for human reproduction:

  • Males produce sperm in the testes. The sperm is then transported through the male reproductive tract and eventually ejaculated during sexual intercourse or ejaculation.

  • Females have eggs (ova) produced in the ovaries, and pregnancy occurs when a sperm fertilizes an egg.

In cases of assisted reproductive technologies, sperm can be obtained through various methods, including sperm donation or extraction techniques, but the basic biological process involves males producing sperm. If you have any more questions or need clarification, feel free to ask!

So only through the male sperm right

Yes, in the context of natural conception, sperm comes exclusively from the male reproductive system. Fertilization of an egg by a sperm requires the sperm produced by a male.

When a male and female engage in sexual intercourse, the male ejaculates sperm into the female's vagina, which can then travel through the cervix and uterus to meet and fertilize an egg that has been released during ovulation.

If you have more questions about reproduction or related topics, feel free to ask!

So that’s it right? Only through the male

Yes, that's correct. In natural reproduction, sperm, which is produced by males, is necessary for fertilizing an egg from a female. The sperm must meet the egg to create a pregnancy, and this typically happens during sexual intercourse when the male ejaculates sperm into the female's reproductive system.

To summarize:

  1. Males produce sperm in their testes.
  2. Females produce eggs (ova) in their ovaries.
  3. Fertilization occurs when a sperm from the male successfully meets and fertilizes an egg from the female.
