T.S. Penis *

"What is Penis ?



It is a cylindrical, erectile and copulatory organ. It forms the external genitalia of male. It is supported by three erectile tissues two dorsal, yellow fibrous ligamentous corpora cavernosa and one ventral, highly vascular and spongy corpus spongiosum which surrounds the urinogenital canal. Tip of penis is highly sensitive and is known as glans penis. It is covered by a retractile skin fold called foreskin or prepuce. Glans is with a slit-like opening of urinogenital canal called urethral meatus.

* Functional : --

. Penis helps in insemination. Erection of penis is due to rush of artรฉrial blood (about 10 times more) into the sinuses of corpus spongiosum aided by contraction of erector penis muscles.

Reproductive Technology ✍๐Ÿป

*Reproductive Technology! !  Reproductive technology encompasses various medical techniques to enhance fertility and increase conception chances. Here's a rundown of key terms and technologies: *Types of Reproductive Technologies:* - *IVF (In Vitro Fertilization)*: Fertilizing an egg with sperm outside the body and transferring the embryo into the uterus. - *ICSI (Intracytoplasmic Sperm Injection)*: Injecting a single sperm directly into an egg to overcome fertilization issues. - *ART (Assisted Reproductive Technology)*: Includes IVF, ICSI, and other techniques to assist reproduction. - *IUI (Intrauterine Insemination)*: Placing sperm directly into the uterus to bypass cervical barriers. - *GIFT (Gamete Intra-Fallopian Transfer)*: Transferring eggs and sperm into the fallopian tube for fertilization. - *ZIFT (Zygote Intra-Fallopian Transfer)*: Transferring a fertilized egg into the fallopian tube. - *PGD (Preimplantation Genetic Diagnosis)*: Testing embryos for genetic disorders be...

Structure of Ovum ๐Ÿ‘‡๐Ÿป

 " STRUCTURE of OVUM " Definition .:--Ovum is a maternal haploid gamete and is primarily concerned with receiving the sperm and is determined to develop into a fully developed multicellular organism after fertilization (syngamy) or without fertilization (parthenogenesis). It is generally with reserve food and is genetically programmed. Structure. An ovum is generally spherical, non-motile gamete with yolky cytoplasm and enclosed in one or more egg envelopes. Size of ovum varies in different animals and depends upon the amount of yolk. Size of ovum varies from 10 ยต to a few cm. The largest sized egg is of ostrich and is about 170 x 135 mm. Egg size and yolk amount are interdependent. It is about 50 ยต in many polychaete worms, 150 ยต in tunicates but very large sized in birds and reptiles. In mammals, it is generally microlecithal and about 100 ฮผ. Human ovum is microlecithal with large amount of cytoplasm. Cytoplasm is differentiated into outer, smaller and transparent exoplasm ...

What is Bioethics ⁉

Image
 " What is Bioethics ? Certain acts are regulated by communities to consider their legitimacy. Such regulation is called ethics. Bioethics include standards followed by us to regulate the activities linked with biological activities. Unexpected methods are being adopted in the fields of biology like recombinant DNA technology and pharmaceutical studies. Bioethical concerns related to biotechnology are: (i) For the production of pharmaceutical products like proteins many animals are reduced to the status of factory. (ii) Animals undergo great physical sufferings while performing experiments on them. (iii) There is violation of 'integrity of species' due to transferring of a transgene from one species to another. (iv) 'Concept of humanness' is diluted due to introduction of human genes to various animals or vice versa. (v) Biotechnological studies have been considered as mere exploitation of living beings. (vi) Biodiversity may be affected due to biotechnological exp...
