Latest Muscle and Neural Tissue MCQ Objective Questions
Muscle and Neural Tissue Question 1:
Choose incorrect statement regarding types of muscle fibres.
Answer (Detailed Solution Below)
Muscle and Neural Tissue Question 1 Detailed Solution
The correct answer is Plenty of mitochondria are present in white muscle fibres.
Explanation:
Muscle contains a red coloured oxygen storing pigment called myoglobin.
- Myoglobin content is high in some of the muscles which gives a reddish appearance. Such muscles are called the Red fibres.
- These muscles also contain plenty of mitochondria which can utilise the large amount of oxygen stored in them for ATP production.
- These muscles, therefore, can also be called aerobic muscles.
- Some of the muscles possess very less quantity of myoglobin and therefore, appear pale or whitish. These are the White fibres.
- Number of mitochondria are also few in them, but the amount of sarcoplasmic reticulum is high.
- They depend on anaerobic process for energy.
Muscle and Neural Tissue Question 2:
Read the assertion and reason carefully to mark the correct option out of the options given below:-
Assertion: Cardiac muscle look like syncytium but histologically it is not syncytium
Reason: Cardiac muscle fibers branch and interdigitate, but each is a complete unit surrounded by cell membrane with a centrally located single nucleus
Answer (Detailed Solution Below)
Muscle and Neural Tissue Question 2 Detailed Solution
- Syncytium refers to a single cell mass containing numerous nuclei, usually caused due to fusion of cells.
- Muscles are divided into 3 major classes:
Important Points
- Cardiac muscle look like syncytium but histologically it is not syncytium: Assertion is TRUE
- It does look like a syncytium with multiple nucleus.
- From the above table we see that cardiac muscles are uninucleate.
- Thus, it cannot be a syncytium histologically.
- Reason is TRUE
- Cardiac muscle fibers are joined end-to-end by flat zig-zag junctions called intercalated discs.
- The fibers are interconnected by oblique bridges, forming a network.
- This gives the look of a syncytium, but they are actually individual fibers.
- They are also branched muscle fibers with interdigitation.
- Each fibre has a centrally located nucleus and covered by a special covering sarcolemma.
