TESTIS

MALE REPRODUCTIVE SYSTEM

 

It consist of the

2 testis

2 epididymidus

2 deferent ducts

2 seminal vesicles

2 ejaculatory ducts.

1 prostate  gland

1 penis.

SCROTUM:-

           

            Scrotum in a  of deeply pigmented skin fibrous & connective tissue & smooth muscle

It is divided into 2 compartments each contains one, testis & 1 epididymis & the testicular  end of a spermatic cord.

It lies below the symphysis pubis

TESTES:-

1.      INTRODUCTION: the testes are the reproduction gland of the male reproductive gland.

2.      SITUATION:- it lies in the scrotum.

3.      SHARE:- oval shape

4.      MEASUREMENTS:

LENGTH                -                 4.5 cm

WIDE                      -                 2.5 cm

THICKNESS          -                     3 cm

5.      LAYERS OF TISSUE.

 

1.      The Tunica vaginalis

2.       Tunica albuginea.

3.      Tunica Vasculosa

1.      Tunica Vaginalis:-    it is a outer covering of the Testis

It is double membrane forming structure.

2.      Tunica albuginea:-  this is a fibrous covering beneath the tunica vaginalis that surrounds the testis

It divides the glandular structure of the testis into lobules.

3.      Tunica Vasculosa:-   this consists of a network of capillaries supported by delicate connective tissue.

6.      STRUCTURE OF THE TESTES:-

1.      Testes are 200 to 300 lobules  and within  each lobule 1-4 convoluted loops composed of germinal epithelial cells, called seminaferons tubules.

Between the tubules there are groups of interstitial cells (of leydig)

It secrete testosterone hormone after puberty

Length of the tubule is 6 cm in full length & it is repeateadly folded & tightly packed  into a mass called “the Epididymis)

Blood & lymph vessels pass to the Testis in the operatic cords.

FUNCTIONS:

Production of  spermatozoa (Sperm)

Production of FSH

It helps for Spermatogenesis.

STRUCTURE OF THE SPERM.

PUBERTY IN THE MALE.

It occurs b/w the ages of 10 & 14.

L H from the anterior lobe of the pituitary gland stimulate the interstial cells of the testis to increase the production of testosterone.

This Harmone influences the development of the body to sexual maturity.

THE CHANGES IN PUBERTY.

Increases the growth of muscle, bone & Height & Weight.

enlargement of the larynx and deeping of the voice it breaks.

Enlargement  of the penis,scrotum & prostate gland.

Growth hair on the face axillae, chest,abdomen and pubis.

The skin  thickens  & Become more oilier
