The Skeletal System: Bones, Joints, and Cartilage

Long bones are characterized by their length and cylindrical shape. Examples of long bones include the femur, tibia, and humerus.

The synovial membrane is a thin layer of tissue that lines the inner surface of a joint. It produces synovial fluid, which lubricates the joint and reduces friction between the bones.

Fibrocartilage is a type of cartilage that is found in the intervertebral discs, which are located between the vertebrae in the spine. It is a strong and flexible type of cartilage that can withstand compression and tension.

The elbow joint is a hinge joint that connects the humerus to the ulna and radius. It allows for flexion and extension of the forearm.

Flat bones are characterized by their flat and thin shape. Examples of flat bones include the scapula, sternum, and ribs.

Articular cartilage is a thin layer of cartilage that covers the ends of bones in a joint. It provides cushioning between the bones and reduces friction during movement.

Elastic cartilage is a type of cartilage that is found in the trachea and bronchi. It is a flexible type of cartilage that can withstand bending and stretching.

The ankle joint is a hinge joint that connects the tibia and fibula to the talus. It allows for plantar flexion and dorsiflexion of the foot.

Irregular bones are characterized by their short and irregular shape. Examples of irregular bones include the vertebrae, sternum, and hip bones.

The meniscus is a C-shaped piece of cartilage that is located in the knee joint. It provides cushioning between the femur and tibia and helps to stabilize the joint.

Elastic cartilage is a type of cartilage that is found in the ear. It is a flexible type of cartilage that can withstand bending and stretching.

The knee joint is a hinge joint that connects the femur to the tibia and fibula. It allows for flexion and extension of the leg.

Sesamoid bones are small, round bones that are embedded in tendons. They help to protect tendons from friction and wear.

Ligaments are tough bands of tissue that connect bones together. They help to stabilize joints and prevent them from dislocating.

Hyaline cartilage is a type of cartilage that is found in the nose. It is a smooth and flexible type of cartilage that allows for easy movement of air.
