10ข้อเท็จจริงที่คุณควรรู้เกี่ยวกับ sperms

สเปิร์ม (พหูพจน์: ตัวอสุจิ) กับสเปิร์มหรือชื่อวิทยาศาสตร์เต็มรูปแบบเป็นเซลล์สืบพันธุ์ที่เป็นของบุคคลชาย.

การผลิตเซลล์เหล่านี้ในลูกอัณฑะเริ่มต้นในช่วงวัยแรกรุ่น มันมีข้อมูลทางพันธุกรรม (ดีเอ็นเอ) ที่มันจะโอนไปไข่ในระหว่างการปฏิสนธิในส่วนหัว. เขามีหางและเขากำลังเคลื่อนไหว ในมนุษย์, ประมาณ150-200 ล้านตัวอสุจิจะถูกปล่อยออกมาในระหว่างการผสมพันธุ์. อย่างไรก็ตาม, เพียงหนึ่งเซลล์อสุจิสามารถปุ๋ยไข่. เมื่ออสุจิมาถึงเซลล์ไข่ (oocyte), มันออกจากหางด้านนอกเพื่อเข้าสู่ไข่และส่งผ่านข้อมูลทางพันธุกรรมไปยังไข่. พบในของเหลวที่หนาแน่น ชื่อของของเหลวนี้เป็นน้ำอสุจิ (ersuyu), การฉีดยาหรือใช้กันทั่วไปในรูปแบบของ sperma

หัวของสเปิร์มที่มีลักษณะคล้ายพลั่วของเบเกอร์และมีข้อมูลทางพันธุกรรม มีโครงสร้างที่เรียกว่า akzoroma ที่ห่อส่วนหัวเช่นหมวกและมีเอนไซม์ที่จำเป็นสำหรับการที่จะผ่านผนังเซลล์ไข่ เมื่อเซลล์อสุจิถึงไข่, เอนไซม์ใน acrosome เมมเบรนจะถูกปล่อยออกมา, ช่วยให้อสุจิที่จะเข้าสู่ไข่. จำนวน n ของวัสดุดีเอ็นเอของชายที่มาพร้อมกับจำนวนของวัสดุดีเอ็นเอของหญิงและประกอบด้วยตัวเลข2n ของวัสดุดีเอ็นเอ (เซลล์นี้เรียกว่า zygote). จากนั้นใน zygote เซลล์จะเริ่มคูณด้วยการแบ่ง โครโมโซม X และ Y ที่ถูกดำเนินการโดย sperรมา zoas ในการก่อตัวของเพศจะเด็ดขาด เมื่อเซลล์สืบพันธุ์หญิงดำเนินการโครโมโซม x, ครึ่งหนึ่งของเซลล์สืบพันธุ์ชาย X และอีกครึ่งหนึ่งดำเนินการโครโมโซม Y. ถ้าเซลล์สืบพันธุ์ของหญิงเป็นปุ๋ยที่มีการปฏิสนธิกับ X โครโมโซม, โครโมโซมกลายเป็น XX และเพศของแต่ละบุคคลกลายเป็นผู้หญิง, ในขณะที่ตัวอสุจิที่ดำเนินการ Y เป็นปุ๋ย, เพศของแต่ละบุคคลจะกลายเป็นชาย. อย่างไรก็ตามมีข้อยกเว้นบางอย่าง เช่น xxy, X0 อาจเกิดขึ้นกับบุคคลที่เป็นโรคทางพันธุกรรม.

แม้ว่าสเปิร์มจะพูดในโลกทางการแพทย์, ผลกระทบ, ผลประโยชน์หรือเนื้อหาแทบจะไม่ได้พูดโดยมนุษย์. แต่ข้อมูลเกี่ยวกับมันเป็นที่น่าสนใจอย่างมาก นี่คือ10ข้อมูลที่น่าสนใจที่คุณไม่ทราบเกี่ยวกับสเปิร์ม
