Questions Related to skeletal muscles

Multiple choice zoology movement and locomotion in man structure of skeletal muscle muscles and their structure skeletal muscles

Which muscles having functionally multinucleated conditions?

  1. Cardiac muscle

  2. Smooth muscle

  3. Voluntary muscle

  4. All of these
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

There are cardiac, skeletal and smooth muscle cells of which only skeletal or voluntary muscle cells are multinucleated. Such cells are syncytial. Skeletal muscle cells arise in the embryo as uninucleated entities. Later the cells fuse to give rise to the multinucleated muscle fibre.

So the correct answer should be option C "voluntary muscles".

Consider the following statements each with one or two blanks.
(i) Each half of pectoral girdle consists of a (A) and a (B) 
(ii) (C) is a condition of rapid spasms (wild contractions) in muscle due to low $Ca^{++}$ in body fluid.
(iii) Each organised skeletal muscle In our body is made of a number of (D) held together by a common collagenous connective tissue layer called (E) Which one of the following options correctly fills the blanks in any two of the statements ?

  1. (C) - Muscular dystrophy, (D) - fascia, (E) - fascicle

  2. (A) - clavicle, (B) - scapula, (C) - Tetany

  3. (A) - ilium, (B) - ischium, (D) - fascicles, (E) - fascia

  4. (C) - Myasthenia gravis, (D) - fascicles. (E) - fasda

B Correct answer
Explanation

Each half of pectoral and pelvic girdle consist of clavicle & scapula, tetany is a condition of rapid spasms in muscle due to low calcium ion in body fluid.

So, the correct option is '(A) - clavicle, (B) - scapula, (C) - Tetany'.
