A Trivia Quiz On Muscle Anatomy!
-
Which one has the largest dimeter?
-
Skeletal muscle
-
Smooth muscle
-
Cardiac muscle
-
Muscles are made of specialized cells called muscle fibers. The predominant function of muscle fibers is contractibility, which is responsible for all the body movements and the protection of organs. This quiz is about the anatomy of the human muscle system. So, attempt all the nine questions in this trivia to test how much do you know about the topic.

Which one is multi nuclei?
-
Smooth muscle
-
Skeletal muscle
-
caradic muscle
Correct Answer
A. Skeletal muscleExplanation
Skeletal muscle is the correct answer because it is the only type of muscle that contains multiple nuclei. Smooth muscle and cardiac muscle have a single nucleus per cell. Skeletal muscle, on the other hand, is made up of long, multinucleated cells called muscle fibers. These multiple nuclei are necessary for the muscle fiber to efficiently carry out its functions, such as muscle contraction and repair.Rate this question:

Which one of the following not striated?
-
Cardiac muscle
-
Skeletal muscle
-
Smooth muscle
Correct Answer
A. Smooth muscleExplanation
Smooth muscle is the correct answer because it is the only type of muscle that is not striated. Both cardiac muscle and skeletal muscle have a striated appearance due to the arrangement of contractile proteins within the muscle fibers. Smooth muscle, on the other hand, lacks this striated appearance and has a more uniform and smooth appearance. Smooth muscle is found in the walls of organs and blood vessels and is responsible for involuntary movements.Rate this question:

The branching in muscle happen in:
-
Smooth muscle
-
Skeletal muscle
-
Cardiac muscle
Correct Answer
A. Cardiac muscleExplanation
The branching in muscle occurs in cardiac muscle. Cardiac muscle is found only in the heart and is responsible for the contraction and relaxation of the heart chambers. The branching nature of cardiac muscle allows for coordinated and synchronized contraction of the heart, ensuring efficient pumping of blood throughout the body. Smooth muscle and skeletal muscle do not typically exhibit branching to the same extent as cardiac muscle.Rate this question:

Which one never regenerates?
-
Smooth muscle
-
Skeletal muscle
-
Cardiac muscle
Correct Answer
A. Cardiac muscleExplanation
Cardiac muscle is the correct answer because unlike smooth muscle and skeletal muscle, cardiac muscle cells have a limited ability to regenerate. When cardiac muscle cells are damaged, they are typically replaced by scar tissue rather than new muscle cells. This is why conditions such as heart attacks can lead to permanent damage to the heart muscle. In contrast, smooth muscle and skeletal muscle have the ability to regenerate and repair themselves to some extent after injury.Rate this question:

Cytoplasm in smooth muscle is:
-
Acidophilic
-
Basophilic
-
Non above
Correct Answer
A. AcidophilicExplanation
Smooth muscle cells contain a large amount of cytoplasm, which appears acidophilic due to the presence of abundant mitochondria and myofilaments. Acidophilic refers to the affinity of the cytoplasm for acidic stains, such as eosin, which gives it a pink or red color when stained. This staining characteristic is due to the high concentration of proteins and other acidophilic substances in the cytoplasm. Therefore, the correct answer is acidophilic.Rate this question:

The shape of smooth muscle is:
-
Circular
-
Cylindrical
-
Fusiform
Correct Answer
A. FusiformExplanation
Smooth muscle is a type of muscle tissue found in the walls of organs and structures such as blood vessels and the digestive system. It is characterized by its ability to contract and relax involuntarily. The shape of smooth muscle is described as fusiform, which means it is elongated and tapered at both ends. This shape allows smooth muscle cells to generate force in a specific direction, facilitating their role in various bodily functions such as peristalsis and blood flow regulation.Rate this question:

Cardiac muscle has:
-
Numerous mitochondria
-
Few myofibrils
-
Intercalated discs
-
All above
Correct Answer
A. All aboveExplanation
Cardiac muscle has numerous mitochondria, which are responsible for producing energy for the muscle to contract. It also has few myofibrils, which are the contractile units of the muscle. Additionally, cardiac muscle has intercalated discs, specialized junctions that allow for synchronized contraction of the muscle fibers. Therefore, all of the given options are correct.Rate this question:
