anatomy and physiology. Explain how a buffer pair would react if more hydrogen ions were added to the blood. 1 / 4. Find step-by-step Anatomy and physiology solutions and your answer to the following textbook question: Differentiate between spermatogenesis and oogenesis. How do these differences relate to the role of the male and female in
The testis produces gametes through spermatogenesis and evolves rapidly at both the morphological and molecular level in mammals 1 – 6, probably owing to the evolutionary pressure on males to be reproductively successful 7. However, the molecular evolution of individual spermatogenic cell types across mammals remains largely uncharacterized.
Spermatid development, or spermiogenesis, extends over 22.7 days in rats and 21.6 days in humans. Formation of the acrosome is a key event in spermatid development. The acrosome is a membrane-bound organelle on the surface of the nuclei of spermatids and spermatozoa. Acrosome formation begins in the early spermatid by coalescence of
Spermatogenesis is the process of sperm production and occurs in the seminiferous tubules of the human male testes. The seminiferous tubules make up the bulk of each testis. The testes also contain specific interstitial cells (Leydig cells) that secrete the hormone testosterone.
During spermatogenesis, from the late spermatocyte stage to the mature spermatozoa, the mitochondria of the germ line cells change from a classic structure to a more condensed and a more active structure (Ramalho-Santos et al., 2009). During spermiogenesis, a large part of the cell cytoplasm (including mitochondria) is eliminated in the form of
