Abstract


In this paper, vivisection and tissue slices and electric mirror technology mainly mansoni no needle squid spermatophore structure formation, the process of radiation, sperm sac of adhesion and sperm of storage, etc. carried out a preliminary study, the results are as follows: Man needle-free squid sperm The structure of the pod is constituted by a fine group, gluing body radiation catheter, each film gap liquid substances. Fine group, located in the the spermatophores end of their centers for mucus shaft, sperm rope winding the mucus-axis to form sperm groups. Gluing body located between the the spermatophore radiation catheters fine group, with an arrow-shaped structure at its head. Radiation catheter is constituted by the the mucus tube and films. Spermatophores outer envelope is outside the top to form a cap structure and the crown line. The film close to the outer coating, the film is thick, having a strong absorbent. Within the film, close to the sperm group, thinner. Filled with the liquid substance between the inner coating and coating, with lubricating and delivery pressure of the role. Man without needle squid spermatophores by the vas deferens, mucous glands, radiation catheter gland capsule gland, outer envelope gland, hard gland end gland and other glands, relying on the connective tissue connected Waipi capsule form oval cystic structure; sperm through the vas deferens transported to the mucous glands formation of sperm Mission; spermatophore in radiology catheter glands, radiation catheter structure and adventitia, in the film, endometrial and within the envelope formation; spermatophores in capsule gland The coating is formed; outer envelope gland, the spermatophores outer capsule formation; through the hard glands and final gland spermatophore form a complete structure, spermatophore sac after spermatophore tube into the store, mature, for the use of the breeding season. The mansoni needle squid spermatophores radiation is mainly caused by the crown line traction and seawater penetration. Radiation reaction process is a continuous growing process, from the rupture of the cap structure of the spermatophore, spermatophores radiation catheter pulls out quickly, followed by the glue body and fine group for rotary forward until the glue body I valgus, endometrium, in membrane rupture , glued the body Ⅱ valgus, sperm capsule formation extends back at the same time, the outer membrane rupture, complete sperm sac formation, sperm sac end of free sperm overflow. Man needle squid sperm capsule attached to the mouth of the female film and satisfied seminal vesicle mating season sperm sac large number gluing body structure through the arrow-shaped head and sperm sac attached to the organization. Mansoni needle squid satisfied seminal vesicles, a pair of milky white in the mouth membrane protrusions. Was ramose, to thylakoid formation of varying sizes, each thylakoid interconnected. Is surrounded by a large amount of muscle tissue, each thylakoid around a lot of cubic ciliated epithelial cells and intermediate cysts, the cell nucleus Jieyou oval. The sperm normally present in the orderly arranged satisfied seminal vesicle capsule bottom, surrounded by the particulate material, the particulate material having a role of inhibiting metabolism.
