The Elastic cartilage a, described in Britannica, is yellow in appearance is more pliable than the other two forms because it contains elastic fibers and collagen. In humans, it makes up the external ear, the auditory tube of the middle ear, and the epiglottis. Want to know more?

What is Dense connective tissue? According to Rachel Baxter, a dense regular connective tissue comprises type I collagen fibers. It is found in areas of the body where large amounts of tensile strength are required, like ligaments, tendons, and aponeurosis. The collagen fibers are densely packed together and arranged in parallel. This arrangement allows the fibers to have excellent resistance to forces pulling along a single axis and gives some ability to stretch. Tendons and ligaments attach to bones, and the role of dense regular connective tissue is to transfer forces to bones. Read more: https://www.kenhub.com/en/library/anatomy/dense-connective-tissue

Bone tissue is a tissue that gives strength and structure to bones. Bone comprises compact tissue (the hard, outer layer) and cancellous tissue (the spongy, inner layer that contains red marrow). Bone tissue is maintained by bone-forming cells called osteoblasts and cells that break down bone called osteoclasts. Bones also contain blood vessels, nerves, proteins, vitamins, and minerals. It is also called osseous tissue. More informations here:https://www.cancer.gov/publications/dictionaries/cancer-terms/def/bone-tissue
