Aim: To study and identify the transverse section of testes and ovary through permanent slides.
Requirements: Permanent slides of transverse section of Testes and ovary, microscope
Observation:
T.S of Mammalian Testes
The mammalian testes are covered with a thick fibrous tissue called tunica albuginea
The testes consist of a many seminiferous tubules embedded in the interstitial tissues.
Various types of cells are present from outside towards the lunar in the following order:-
Spermatogonia(2n)———>Spermatocytes ( ) ———>Sepermatids———>Spermatozoa(n) i.e. sperms
Between the germinal cells, pyramidal shaped cells called Sertoli cells are present
A large number of sperms have their head embedded in the Sertoli cells.
The interstitial tissue has Leydig cells which produce testosterone.
T.S. of Mammalian Ovary
A mammalian ovary is a solid structure bounded germinal epithelium followed by a thick layer of fibrous tissue called tunica albuginea.
The ovary consists of the outer cortex and inner medulla.
The medulla consists many rounded or oval bodies called ovarian follicles at various stages of development.
The development of follicle is as follows:-
10 follicle——>20 follicle—–>30 follicle—->Graffian follicle—–>corpus luteum
The cortex contains round and mature follicles along with corpus luteum.
Precaution:
Handle the microscope with care
Use find adjustment for better focus

plz diagram also needed
Diagram is in the book only
these questions are also in the books so why bother ????
Please give more points about ts of ovary
Plz diagram vi bnayen
I need the diagrams of both the gamete development in t.s of testes & ovary… plzz
Give more points on ovary of mammal
Please give it more briefly and please give the procedure too. It’s a must
Diagram needed
Diagram also needed
Plz diagram also needed
Plz diagram also needed and give me more point related to ts of testis
Give some special point for testes and ovary in character
Plz also give blastulla stage
Plzz give more main points about ovary with labelled diagram
we need diagram also
I need more point. Pliz give more point
diagram needed
