The body reabsorbs this fluid as sperm cells travel from the seminiferous tubules to the epididymis.īefore sperm can get to the epididymis, they can’t move. The rete testis helps to mix sperm cells around in the fluid secreted by Sertoli cells. Rete testisĪfter sperm is created in the seminiferous tubules, sperm cells travel toward the epididymis through the rete testis.
These cells produce male hormones, such as testosterone and other androgens. The tissues next to the tubules are called Leydig cells. Among the Sertoli cells are spermatogenic cells that divide and become spermatozoa, or sperm cells. This layer is made up of Sertoli cells that aid in the production of hormones that generate sperm. These tubules are lined with a layer of tissue called the epithelium. The cells and tissues in the tubules are responsible for spermatogenesis, which is the process of creating sperm. Seminiferous tubules are coiled tubes that make up most of each testis. Lobules are made up of coiled tubes surrounded by dense connective tissues. Testes get their ovular shape from tissues known as lobules. They’re also crucial for creating testosterone and other male hormones called androgens.
A case study shows how cross-media publishers could profit from using more elaborate information systems and some of the authoring issues of mixed-media information environments are discussed.The main function of the testes is producing and storing sperm. Specifically, we introduce the iServer framework as a generic link management and extensible integration platform and digitally augmented paper is presented as one specific application of the iServer technology.
In this paper, we discuss the issues of information semantics and granularity that arise in the design of highly interactive mixed-media information systems and present a general, flexible information server that meets the requirements of publishing information on different output channels (cross-media publishing). However, most existing approaches tend to focus on the media technologies rather than on concepts for information integration and linking that enable users to move freely back and forth between various media information sources. Over the last decade, we have seen a significant increase in the number of projects aiming for integration of different kinds of media(mixed-media integration). The system has also been used by an airline company for online security checking and a high school for online mobile learning Part of the implemented system (Pocket SCORM on PDA) received the 2005 Brandon Hall Excellence in Learning Awards. In this way, users can read hardcopy textbooks in a traditional manner while the process of reading conforms to the SCORM specification. With an authoring tool, specially designed tags are printed in textbooks and recognized by hyper pen for user navigation control. A computer, a personal digital assistant, or a cellular phone can be used for user behavior supervision using the hard SCORM machine. Hard SCORM employs a pen-like optical character reader device (called Hyper Pen) as an input mechanism. Our project, Hard SCORM, advances the field by implementing an integrated system which allows learners to read SCORM-compliant textbooks using multimodal multimedia devices. To date, most e-learning systems have been based on multimedia and Web technologies on personal computers.
Since it was announced in late 1990s, the reference model has been used by software developers and academics in the development of authoring tools, learning management systems, and repositories for distance learning content. The sharable content object reference model (SCORM) is a set of specifications and guidelines for the representation and operation of asynchronous distance learning.
