Answer:
The correct answer will be option-C
Explanation:
T-tubules or transverse tubules are the extensions of the cell membrane or into the sarcoplasm of the muscle cells.
The T-tubules play an important role in the movement of the muscle in response to the synaptic signals as they conduct the electrical impulse from the surface of the cell to the inside of the sarcoplasmic reticulum which is the storehouse of the calcium ions of the muscle cell.
Thus, Option-C is the correct answer.
Answer:
The endocrine glands that produce the steroid hormones, such as the gonads and adrenal cortex, arise from the mesoderm. In contrast, endocrine glands that arise from the endoderm and ectoderm produce the amine, peptide, and protein hormones. Because the endocrine glands play pivotal roles both in reproduction and in development, it seems plausible to extend the role of the endocrine system to account for the progressive changes in body structure and function that occur with aging. changes occur that affect the endocrine system, sometimes altering the production, secretion, and catabolism of hormones. For example, the structure of the anterior pituitary gland changes as vascularization decreases and the connective tissue content increases with increasing age. This restructuring affects the gland’s hormone production. For example, the amount of human growth hormone that is produced declines with age, resulting in the reduced muscle mass commonly observed in the elderly.
