Worked practice questions

The portion of the brain that controls balance and coordination of body movements is the:

  1. Cerebrum
  2. Cerebellum
  3. Medulla oblongata
  4. Hypothalamus
Show answer and solution

Correct answer: B. Cerebellum

1. CEREBELLUM (little brain) coordinates voluntary movement, balance and posture. 2. Cerebrum = thinking, memory, decision-making. 3. Medulla = involuntary actions (heartbeat, breathing). 4. Hypothalamus = body temperature, thirst, hunger. _Source: syllabus Science Ch 6 §6.1.3 Human Brain_

The hormone produced by the pancreas that lowers blood glucose level is:

  1. Adrenaline
  2. Insulin
  3. Thyroxine
  4. Glucagon
Show answer and solution

Correct answer: B. Insulin

1. INSULIN, secreted by beta cells of the pancreas (islets of Langerhans), LOWERS blood sugar. 2. Glucagon (alpha cells) RAISES blood sugar — counterpart to insulin. 3. Diabetes mellitus = inadequate insulin production / response. _Source: syllabus Science Ch 6 §6.2 Hormones in Animals_

Thyroxine, which regulates the metabolic rate of the body, is produced by the:

  1. Adrenal gland
  2. Pancreas
  3. Thyroid gland
  4. Pituitary gland
Show answer and solution

Correct answer: C. Thyroid gland

1. THYROID gland secretes thyroxine (T₄) and triiodothyronine (T₃). 2. Thyroxine controls metabolism, growth, energy use. 3. Iodine deficiency → goitre (enlarged thyroid). _Source: syllabus Science Ch 6 §6.2 Endocrine Glands_
