Question

In rabbit, the ends of long bone are connected to one another by
A. Tendon
B. Ligament
C. Muscle
D. Cartilage

Answer 1

There are 23 types of bones which make up the skeleton of a rabbit. The skeleton of a rabbit is less compact than that of a cat, making up just 7% to 8% of its body mass, and can quickly break free from rough handling.

Complete answer:
The endoskeleton of the rabbit consists mainly of bone, and very little of the cartilaginous component. The skeleton of a rabbit can also be divided into two parts, exactly like those of other vertebrates:
1. The axial skeleton comprises the bones of the skull, the vertebral column, the ribs and the sternum along the longitudinal axis of the body.
2. The appendicular skeleton is situated at the right angle of the body's longitudinal axis and consists of limb bones and girdles.
Tendon- Tendons are a specialized type of connective tissue that unites muscle and bone and, as such, have functions that are important for normal mobility. The orientation of fibrous tissue in the tendon supports the hypothesis of a mechanical effect on tendon growth, but there is no strict relationship between muscle strength and tendon thickness and the ratio of their total fascicular cross muscles varies.
Ligament- Ligaments are made of connective tissue and have a lot of strong fibres of collagen in it. They are discovered in the body in various types and sizes. Ligaments often tie two bones together, especially in the joints: they support the joint or keep the ends of two bones together like solid, securely attached strings or ropes. This guarantees that the joint bones do not twist too hard or shift too far apart and become dislocated.
Muscle- With function and location in the body, muscle tissues differ. In mammals, the three forms are: skeletal or striated muscle; smooth or non-striated muscle; and semi-striated cardiac muscle. Smooth and cardiac muscle contracts, without deliberate involvement, involuntarily.
Cartilage- Cartilage is characterized as essentially avascular because it contains substantially fewer vessels than bone, and yet some blood vessels are also found in cartilage. These are found in large vascular canals in mammalian cartilage, hundreds of micrometers in diameter, carrying materials between perichondral regions and deep cartilage tissue.

Hence, the correct answer is (B) Ligament

Note: A ligament 's purpose is to provide a passive limit to the amount of motion between your bones. Collagen fibres are the basic building blocks of a ligament. Such fibres are very strong , flexible and resistant to damage from stresses of pulling or compressing. Collagen fibres are typically organised in parallel bundles, which allow the individual fibres to multiply their power. The outer coating that covers all bones is bound to the bundles of collagen.
