They are called tendons.
Cartilage is a type of connective tissue that is flexible and rubbery, fat tissue stores energy and helps cushion and insulate the body, tendons are tough bands of connective tissue that connect muscle to bone, and ligaments are fibrous bands of connective tissue that connect bone to bone and provide stability to joints.
Marrow
The flexible connective tissue found in sharks is called cartilage. Cartilage provides support and structure to the shark's body, while also allowing for flexibility and movement. This tissue is lighter and more flexible than bone, making it well-suited for aquatic environments.
The connective tissue membrane covering a bone is called the periosteum. It serves to protect the bone, provide nutrients, and support bone growth and repair.
It is called a tendon.
Periosetum is a connective tissue which covers bone. Peri-=around + -osteum=bone.
