Understanding the Skeletal System

This video tutorial by Juan José Sánchez provides an in-depth overview of the skeletal system, its integration with the muscular and articular systems, and its primary functions such as support, protection, and movement facilitation. It explains the division of the skeleton into axial and appendicular parts, describes the structure of bones, and classifies them into different types. The video also highlights the importance of the skeletal system in hematopoiesis and mineral storage.

What is the primary role of the skeletal system?

• To provide energy to the body

• To produce hormones

• To serve as a structural framework

• To regulate body temperature

Which of the following is NOT a function of the skeletal system?

• Digestion of food

• Storage of minerals

• Production of blood cells

• Protection of vital organs

What are the two main divisions of the skeleton?

• Axial and Appendicular

• Cranial and Caudal

• Upper and Lower

• Anterior and Posterior

What is the function of the metaphysis in a long bone?

• To connect muscles

• To protect the bone marrow

• To facilitate bone growth

• To store fat

Which layer of bone is responsible for lining the internal cavity?

• Spongy bone

• Medullary cavity

• Periosteum

• Endosteum

What defines a long bone?

• It is flat and thin

• Its length is greater than its width

• It is found in the skull

• It contains air cavities

Which type of bone is characterized by having a length and width that are similar?

• Irregular bones

• Long bones

• Flat bones

• Short bones

What is a characteristic of flat bones?

• They are longer than they are wide

• They have a reduced thickness

• They are irregularly shaped

• They contain air cavities

Which bones are considered pneumatic?

• Bones with a spongy texture

• Bones with air-filled cavities

• Bones that are flat and thin

• Bones that are accessory

What is the role of sesamoid bones?

• To store minerals

• To change the angle of muscle traction

• To protect the brain

• To support the axial skeleton
