Arten von Knochen

The video tutorial explains the five types of bones based on shape and structure: tubular, short, flat, irregular, and sesame bones. Tubular bones, also known as long bones, are formed through ossification and include the humerus and femur. Short bones are found in the hands and feet. Flat bones, like the ribs and skull, are formed by ossification and handle mechanical stress. Irregular bones include vertebrae and hip bones. Sesame bones, such as the patella, are found near joints and aid in muscle function.

Which type of bone is formed through an intermediate cartilage stage?

• Short bones

• Tubular bones

• Flat bones

• Sesamoid bones

Where are short bones primarily located in the human body?

• In the spine and hips

• In the hands and feet

• In the arms and legs

• In the skull and ribs

What is a characteristic feature of flat bones?

• They are found in the hands and feet

• They have a powerful compact surrounding cancellous bone

• They are formed by indirect ossification

• They are small and found near joints

Which bones are classified as irregular bones?

• Vertebrae and hip bones

• Humerus and femur

• Metacarpals and metatarsals

• Patella and clavicle

What is the primary function of the patella?

• To protect the heart and lungs

• To support the body's weight

• To connect the arm to the shoulder

• To lengthen the lever arm of the quadriceps femoris muscle
