Define spermiogenesis and spermiation.
Spermiogenesis is the process by which spermatids are transformed into spermatozoa (sperms). This occurs after secondary spermatocytes undergo the second meiotic division to produce haploid spermatids.
Spermiation is the process by which the sperm heads, after becoming embedded in the Sertoli cells, are finally released from the seminiferous tubules.
Explanation
The answer is derived from the last paragraph of the provided text. Spermiogenesis is defined as the transformation of spermatids into spermatozoa. Spermiation is defined as the subsequent release of these sperm from the seminiferous tubules after their heads have been embedded in Sertoli cells.
Solution Steps
Step 1: Identify the definition of Spermiogenesis from the text: 'The spermatids are transformed into spermatozoa (sperms) by the process called spermiogenesis.'
Step 2: Identify the definition of Spermiation from the text: '...are finally released from the seminiferous tubules by the process called spermiation.'
Step 3: Combine these definitions into a coherent exam answer, ensuring the context of spermatids and Sertoli cells is included as mentioned in the source.
