Answer:
Many cells in the body have extensions of their cellular menbrana, which depending on their length can be cilia or microvilli, which are the shortest. We see the case, for example, the microvilli found in the small intestine, more abundant at the level of the second and third portions of the intestine, which favors the great absorption of liquids, proteins and nutrients that occur at this level.
Cilia are cellular structures that have a more defined formation and are characterized by their nucleus being made up of proteins and enveloped by the cytosol and plasma menbrana. They are presented as an appendix in the form of hair; We will find these cilia in the cells of the respiratory system and in the reproductive system where they help the mobility of foreign bodies (respiratory system) and the movements of sperm (reproductive system).
Answer:
The correct option is d. All of the above contribute to the pinal gland being called the body's timekeeper.
Explanation:
The pineal gland is a reddish-grey pine-cone shape gland present in the brain. It is responsible for the production of melatonin. The melatonin is a hormone which controls the body's sleep cycle and the circadian rhythm.
The melatonin production is stimulated by darkness. Therefore, the melatonin levels are low during the days and increases at night. This helps in regulating the body's sleep cycle and the circadian rhythm.
Thus, the pineal gland is referred to as the body's timekeeper.
