-
Steroid hormones such as cortisol and testosterone act on their target cells mainly by:
सही उत्तर: घ) entering the cell and binding to intracellular (nuclear) receptors
Lipid-soluble steroid hormones cross the plasma membrane, bind intracellular receptors and the complex regulates gene expression.

Graves' disease (exophthalmic goitre), with protruding eyeballs, enlarged thyroid and raised metabolic rate, is a form of:
सही उत्तर: ग) hyperthyroidism
Graves' disease is an autoimmune hyperthyroidism with excess thyroid hormone, goitre and exophthalmos.

-
Parathyroid hormone (parathormone) mainly:
सही उत्तर: घ) increases the Ca²⁺ level in blood
PTH raises blood calcium by stimulating bone resorption, renal reabsorption of Ca²⁺ and intestinal absorption; calcitonin has the opposite effect.

-
The vestibular apparatus of the inner ear helps in balance. Detection of rotational movements of the head is the function of the:
सही उत्तर: घ) crista ampullaris of the semicircular canals
The crista in the ampulla of each semicircular canal senses angular (dynamic) movement; the maculae of the utricle and saccule sense static position.

The rising phase (depolarisation) of a nerve impulse is caused mainly by the rapid:
सही उत्तर: क) entry of Na⁺ ions into the axon
A stimulus opens voltage-gated Na⁺ channels; Na⁺ rushes in and the inside becomes positive. K⁺ outflow later restores the resting potential (repolarisation).

How many pairs of ribs in humans are 'true ribs', joined directly to the sternum by their own costal cartilage?

Red muscle fibres, which can work for long periods, are rich in:
सही उत्तर: क) myoglobin and mitochondria
Red (slow, aerobic) fibres have plenty of the oxygen-storing red pigment myoglobin and many mitochondria; white fibres have less myoglobin and rely more on anaerobic metabolism.

-
Tetany, with rapid spasms (wild contractions) of muscles, is caused by:
सही उत्तर: ग) low Ca²⁺ in body fluids
Low calcium ion levels (e.g. from hypoparathyroidism) increase nerve and muscle excitability, producing tetany.

-
Osteoporosis, common in elderly women, is an age-related disorder characterised by:
सही उत्तर: क) decreased bone mass and increased chance of fractures
Bone mass falls (low oestrogen after menopause is a common factor), making bones brittle and fracture-prone.
