Chapter 20: Problem 103

Patella, the sesamoid bone is also known as (a) Pisiform (b) Replacing bone (c) Knee cap (d) None of these

Short Answer

Expert verified
(c) Knee cap

Step by step solution

01

Understanding the Exercise

This is a general knowledge question, one needs to know the common name of 'Patella' which is a sesamoid bone in human body. It has nothing to do with calculations or complex problem solving.
02

Evaluate the Options

'Patella' is a medical term. We need to find its equivalent in layman terms from given options. Pisiform is another type of small bone. Replacing bone does not seem related to any specific bone. None of these can be eliminated if any of the previous option is correct.
03

Choose the Correct Answer

By basic knowledge in human anatomy, it is known that 'Patella' is commonly referred to as 'Knee cap'. So the answer must be (c) Knee cap.

Key Concepts

These are the key concepts you need to understand to accurately answer the question.

Patella
The patella is a small yet crucial bone in the human body. It is located in the front of the knee joint. Often called a kneecap, it is a triangular-shaped bone that plays a vital role in our ability to move. When you run, jump, or just simply walk, the patella is actively involved in helping you.
The patella works by providing leverage to your thigh muscles as they contract. This mechanism enhances the stability and movement of the entire leg.
Additionally, the patella shields the knee joint, acting as a protective layer against physical impact.
Sesamoid Bone
Sesamoid bones are unique bones in the human body. They are embedded within tendons and are not attached directly to other bones. The patella is the largest and most well-known sesamoid bone.
These bones occur in areas where a tendon passes over a joint, such as in the knee. Sesamoid bones serve several important functions:
  • They reduce friction, which helps prevent excessive wear and tear on tendons.
  • They can provide a mechanical advantage by changing the angle at which a tendon acts.
Without sesamoid bones, tasks that involve high-stress movements could become difficult and painful.
Knee Cap
Commonly known as the knee cap, the patella is pivotal in maintaining knee functionality. The knee cap enhances the mechanics of the knee by making the muscle action more efficient. It also ensures the knee joint's structural integrity by protecting it from direct impact.
The knee cap also enables smooth extension and flexion of the knee, helping in daily activities such as sitting down, standing up, and climbing stairs. Because of its role, injuries to the knee cap can significantly affect mobility, making it essential to ensure its protection during activities such as sports.
Human Skeletal System
The human skeletal system is a complex framework that supports and protects the body. Comprising 206 bones, it is made up of two main parts: the axial and appendicular skeletons.
The axial skeleton consists of bones in the head, neck, and trunk, while the appendicular skeleton includes the limb bones and the girdles. The patella is part of the appendicular skeleton, playing a key role within the lower limbs.
In addition to providing structure, the skeletal system also facilitates movement, produces blood cells, and stores minerals. Its health is essential for overall vitality and functioning of the human body.

Which of the following is incorrect about ribs? (a) Each rib is a thin and cat bone connected dorsally to the vertebral column and ventrally to the sternum. (b) Ribs has two articulation surfaces on its dorsal end which are called bicephalic. (c) Ventrally ribs are connected to sternum by elastic cartilage. (d) First 7 pairs are called true ribs. The 8,9 and \(10^{\star}\) pair is known as false (vertebracondral) ribs and the 2 pairs (11" and \(12^{\text {th }}\) ) are known as floating ribs.

Smooth muscle fibres are (a) cylindrical, unbranched, striated, multinucleate and voluntary (b) spindle-shaped, unbranched, non-striated, uninucleate and involuntary (c) cylindrical, unbranched, non-striated, multinucleate and involuntary (d) spindle-shaped, unbranched, striated, uninucleate and voluntary

The special contractile protein actin is found in (a) Thick filaments of A-bands (b) Thin filaments of I-bands (c) Both thick and thin bands (d) Whole of myofibril

According to the sliding filament theory (a) Actin (thin filament) moves over myosin (thick filament) (b) Myosin moves over actin (c) Both myosin and actin move on each other (d) None of the above

Assertion: Myosin is structural protein but also act as enzyme. Reason: Myosin is use to form myofibril and can hydrolyse ATP.
