Deficiency in the production of parathormone causes which of the following disease?

Correct answer: D. Tetany

  • A. Brittle bones
  • B. Soft bones
  • C. Rickets
  • D. Tetany

Explanation

Deficiency of parathormone, also known as hypoparathyroidism, leads to decreased blood calcium levels (hypocalcemia). This hypocalcemia increases neuromuscular excitability, resulting in involuntary and sustained muscle contractions known as tetany. Symptoms of tetany can include muscle cramps, spasms, and tingling of the fingers and around the mouth.

About Coordination and Control

Coordination depends on receptors, neurons, synapses and nerve impulses, with reflex actions traced through the reflex arc and the roles of major brain regions. Chemical coordination covers endocrine glands and hormones, including how hormones regulate growth, metabolism, reproduction and internal balance, unlike rapid nervous control.
