There are two types: convoluted and straight, convoluted toward the lateral side, and straight as the tubule comes medially to form ducts that will exit the testis. The seminiferous tubules are formed from the testis cords that develop from the primitive gonadal cords, formed from the gonadal ridge.
The lobules of testis are of partitions of the testis formed by septa of testis. The lobules of testis contain the tightly coiled seminiferous tubule . [ 1 ] There are some hundreds of lobules in a testicle.
The testes are covered by a tough fibrous shell called the tunica albuginea. [5] Under the tunica albuginea, the testes contain very fine-coiled tubes called seminiferous tubules. [5] The tubules are lined with a layer of cells that develop from puberty through old age into sperm cells (also known as spermatozoa or male gametes). [5]
The septa testis are fibrous partitions of the testis dividing the testis into compartments - the lobules of the testis.The septa are formed by extensions of the tunica albuginea - the dense fibrous connective tissue surface covering of the testis - into the substance of the testis.
The periphery of the testicles are converted into the tunica albuginea. Cords of the central mass run together and form a network which becomes the rete testis, and another network, which develops the seminiferous tubules. Via the rete testis, the seminiferous tubules become connected with outgrowths from the mesonephros, which form the ...
The cords of the central mass run together toward the future hilum and form a network which ultimately becomes the rete testis. On the other hand, the seminiferous tubules are developed from the cords distal to the hilum, and between them connective-tissue septa extend. Via the rete testis, the seminiferous tubules become connected with ...
The tubuli seminiferi recti (also known as the tubuli recti, tubulus rectus, or straight seminiferous tubules) are structures in the testicle connecting the convoluted region of the seminiferous tubules to the rete testis, although the tubuli recti have a different appearance distinguishing them from these two structures.
The tunica albuginea is a dense, [1] [2] blue-white [3] layer of fibrous tissue surrounding the testis. [1] [4] It is the middle of three envelopes forming the capsule of the testis; it is deep to the visceral layer of tunica vaginalis, and superficial to the tunica vasculosa testis (vascular layer of testis).
