Muscle Biology Questions

Multiple choice

The different body systems are kept separated by:

  1. muscle tissue

  2. epithelial tissue

  3. nerve tissue

  4. connective tissue
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

It is the simplest tissue and is the protective tissue of the body. The cells of the tissue are tightly packed and it forms a continuous sheet. It covers most of the organs and cavities within the body. It also forms a barrier to keep different body systems separate.

Multiple choice

Binding supporting & packing are the main characteristics of:

  1. epithelial tissue

  2. muscle tissue

  3. connective tissue

  4. nerve tissue

C Correct answer
Explanation

It is a specialised to connect and anchor various body organs. It can connect bones to each other, muscles to bones, bind tissues and give support to various parts of body by forming packing around organs so that they do not get displaced by body movements.It main function is binding supporting & packing.

Multiple choice

Within the body the messages are transmitted by:

  1. epithelial tissue

  2. connective tissue

  3. muscle tissue

  4. nerve tissue
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

A tissue which is specialized to transmit messages in our body is nervous tissue. Brain, spinal cord, and nerves are all composed of nerves tissue. Nervous tissue contains highly specialised unit cells called nerve cells. Nerve cells have the ability to receive stimuli from within or outside the body and conduct to different parts of the body. the impulses travels from one nerve cells to another nerve cell.

Multiple choice

The tissues helping in the movement of body is

  1. Muscle tissue

  2. Epithelial tissue

  3. Connective tissue

  4. Nerve tissue
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The muscle tissue form the contractile tissue are made of muscle cells. Movement of body or limbs are brought about by contraction and the relaxation of the contractile proteins which are present in the muscle cells The movement of the internal organs such as heart and alimentary canal, are all caused by muscle tissues

Multiple choice

Latissimus dorsi is a/an

  1. invertor muscle

  2. abductor muscle

  3. constrictor muscle

  4. adductor muscle

  5. depressor muscle
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Latissimus dorsi is an adductor muscle which brings the arms towards the body.

Multiple choice

Body stiffening after death is due to

  1. muscle tension

  2. treppe

  3. muscle twitch

  4. muscle tonus

  5. rigor mortis
Reveal answer Fill a bubble to check yourself
E Correct answer
Explanation

It is the stiffening of the body after death. It is caused by non-separation of actin myosin complex due to the non-availability of ATP/CTP.
