Question

Cartilage present at the tip of nose is
A) Elastic cartilage
B) Hyaline Cartilage
C) Fibrous Cartilage
D) Calcified Cartilage

Answer 1

Hint: Tissue is a group of cells along with intercellular substances that performs a specific function. Epithelial, Muscular Neural and Connective tissues are the four different types of tissues present in humans. Cartilage is a type of specialized connective tissue.

Complete Answer:
Cartilage and bone are supportive connective tissues which help in maintaining correct posture and support internal organs.
There are mainly three different types of cartilage namely Hyaline, elastic and fibrous. Cartilage is mostly present in the embryonic stages and replaced by bones in adults. The main function of cartilage is to work as a supporting skeleton. Bones of the vertebral column, in the external ear, nose and hands are the areas where cartilage can be seen. The cartilage consists of chondrocytes cells, which are enclosed in a hard, rubbery matrix, secreted by them. Additional strength is due to secretion of collagen fibres. Even though cartilage has elastic properties it is firm too. Nerves, blood and lymph vessels are absent in cartilage.
The type of cartilage present at the tip of the nose is Hyaline Cartilage.
Elastic cartilage is found in the external or outer part of the ear. It has moderate elasticity.
Fibrous cartilage is mainly found in pubic symphysis
Calcified cartilage is found in the end of long bones and in the head of the humerus and femur.

So, the correct answer is Option B.

Notes:
Connective tissues contain three types of fibres namely collagen, elastic and reticular.
Collagen fibres are the most abundant and are made up of fibrous protein, collagen. They have high tensile strength.
Elastic fibres possess high elastic properties.
Reticulate fibres are composed of collagen and glycoproteins.
