Question -
What is the meaning of motile and contractile with respect with to Microvilli , Kinocilia and Stereocilia ?
Please explain.
Best answer would be marked as brainliest.
Answers
Answer:
Stereocilia' are non-motile, distinct from cilia and microvilli. In structure, they are longer than typical microvilli and have more of the characteristics of the cellular membrane proper.
The epididymis is a tube that connects a testicle to a vas deferens in the male reproductive system. The stereocilia of the epididymis helps in absorption. They are long cytoplasmic projections that have no motility. Thus, the correct answer is option
Common Confusions
The morphologies of certain tissues and organs can appear quite similar, making it difficult for a student to differentiate between them. The ability to successfully tell one tissue, or organ, cell, or organelle apart from another requires that you look for specific telltale features. Often those telltale features relate to the different functions of the two confusing structures. A basic approach to all identifications is to bear in mind the inseparability of:
morphology function location
Function is reflected in morphology and in location. As an example, consider the plasma cell. The plasma cell synthesizes and secretes antibodies: its function. Morphologically, it is characterized by a pale-staining cytocentrum where the ribosome-free Golgi apparatus packages those antibodies and an ample cytoplasm that is basophilic because of the presence of many protein-synthesizing ribosomes. Its ubiquitous location in connective tissues underlying epithelia is where antibody-producing cells are most effective in their role in the immune system.
Illustrated in this section are several commonly confused cells, tissues, and organs. The text in this section provides some functionally relevant suggestions on how to differentiate between and among commonly confused structures. It is good practice to use more than one functionally relevant feature to identify items: one for initial identification and one or two more to confirm that identification. The Taxonomic Key to Histological Organs (Appendix B) provides a more complete means for comparison among organs in tabular form.
