Normal practice, or a Simulated test

Both use the same questions. Normal practice is untimed and needs no account: choose an option and the answer and solution appear at once. The Simulated test is the real computer-based format, with one 30-minute clock, a question palette and full screen, and your score, the key and the solutions arrive when you submit.

How the two modes differ
No account needed

Normal

Untimed

Every question on one page, loading as you scroll. Choose an option and see straight away whether it was right.

  • No timer. Nothing to start and nothing to submit. Stop whenever you like.
  • Answered as you choose. Tap an option and it is marked at once, with the correct answer shown.
  • Solutions in place. The explanation, and the video where one has been added, sit under the question.
  • Open to guests. Normal practice needs no sign-in.
Real exam conditions

Simulated

Timed CBT

The computer-based test format: one clock, a question palette, and a score the moment you submit.

  • A clock that does not pause. 30 minutes from the moment you begin, and the paper is submitted for you when it reaches zero.
  • Question palette. Answered, not answered and marked for review, section by section, as the real interface has it.
  • Full screen, proctored. The test takes over the screen; leaving it three times submits the paper.
  • Answers hidden until you submit. The key, the explanations and your score all arrive together at the end.

About this test

Level 2 Nervous and Endocrine Systems GK Quiz on Brain and Hormones

This Level 2 General Awareness biology set on Aptitude360 is a medium-level quiz that combines nervous system and endocrine system topics. It tests impulse transmission, reflex action, brain regions, the hypothalamus and pituitary, and hormone feedback. Questions come in match-the-list, odd-one-out, sequencing and statement-based formats.

Topics in this Level 2 control and coordination quiz

  • Order of events as information passes from one neuron to the next
  • Reflex arcs in the spinal cord, where a reflex can trigger withdrawal of the hand before conscious awareness of pain
  • Functions controlled by the medulla and cerebellum, and protection of the brain by fluid
  • How the hypothalamus signals the pituitary gland
  • Matching glands with hormones: adrenal, thyroid, pancreas and pituitary
  • Insulin feedback when blood sugar rises, and the sequence of an adrenaline response
  • Disorders linked to deficiencies, such as goitre, dwarfism and diabetes

Key concepts for medium-level nervous and endocrine questions

  • The difference between voluntary movements made precise by the cerebellum and involuntary functions controlled by the medulla
  • Feedback mechanisms that control the timing and amount of hormone released
  • Hormones responsible for puberty changes in males and in females
  • Why iodine is needed for thyroxin and how its lack leads to goitre

Preparation tips for statement and matching questions

  • Watch for distractors in disorder lists, such as scurvy, which is caused by a vitamin deficiency rather than a hormone deficiency
  • Practise putting reflex and emergency responses in order until the sequence comes to you quickly
  • Learn each gland with its hormone and one effect together, so matching questions become quick eliminations

Who should take this Level 2 quiz

This quiz suits General Awareness aspirants who have finished the basics and want to practise application-based biology questions.

FAQs about Nervous and Endocrine Systems – GK Quiz with Answers – Level 2

What are the nervous and hormonal systems together responsible for?
Together, they control and coordinate body activities. They also keep internal conditions, such as blood sugar, within a normal range.
Which part of the brain controls involuntary actions?
The medulla in the hind-brain controls involuntary actions such as blood pressure, salivation and vomiting.
Why is iodised salt recommended in the diet?
The thyroid gland needs iodine to make thyroxin. A lack of iodine can cause goitre, in which the neck appears swollen.
What is the function of the cerebellum?
The cerebellum maintains posture and balance and makes voluntary movements precise. It helps with actions such as walking in a straight line or riding a bicycle.
