1. Which of the following glands is NOT directly controlled by the pituitary gland?

• A. Thyroid gland
• B. Adrenal glands
• C. Pancreas (islets of Langerhans)
• D. Parathyroid glands

Correct answer: C

Rationale: The correct answer is C. The pituitary gland is often referred to as the 'master gland' because it secretes hormones that control the functions of other endocrine glands. The thyroid gland (A), adrenal glands (B), and parathyroid glands (D) are directly controlled by the pituitary gland through the release of specific hormones. However, the pancreas, specifically the islets of Langerhans (C), is not directly controlled by the pituitary gland. The pancreas is regulated by hormones such as insulin and glucagon, which are not secreted by the pituitary gland. Therefore, option C is the correct answer as it is not directly influenced by the pituitary gland's hormonal regulation.

4. What is the involuntary process of emptying the bladder called?

Correct answer: B

Rationale: The correct answer is B: 'Micturition.' Micturition, also known as urination, is the involuntary process of emptying the bladder. During micturition, the bladder contracts while the sphincter muscles relax, allowing urine to be expelled from the body. Filtration (A) is the process of separating substances based on their size as they pass through a filter. Reabsorption (C) refers to the process of reclaiming substances from the filtrate in the renal tubules back into the bloodstream. Excretion (D) is the process of eliminating waste products from the body through urine, feces, sweat, or other means. Therefore, micturition is the specific term that describes the act of emptying the bladder involuntarily.
