Skeletal System 2

What are the three main types of joints?

• Fibrous joints, Cartilaginous joints, Synovial joints

• Ball-and-socket joints

• Hinge joints

• Pivot joints

Describe the structure of a synovial joint.

• A synovial joint consists of a joint capsule, synovial fluid, articular cartilage, ligaments, and a synovial membrane.

• A synovial joint is made up of bones and tendons only.

• A synovial joint is characterized by a lack of movement.

• A synovial joint contains only cartilage and ligaments.

What is the primary function of hinge joints?

• To allow rotation in multiple directions

• To enable gliding movements between bones

• To provide stability and support for weight

• The primary function of hinge joints is to allow movement in one direction, enabling flexion and extension.

Name a type of joint that allows for rotational movement.

• Hinge joint

• Ball-and-socket joint

• Pivot joint

• Saddle joint

What role do tendons play in the muscular system?

• Tendons connect bones to bones, providing stability.

• Tendons connect muscles to bones, facilitating movement.

• Tendons are responsible for blood circulation in muscles.

• Tendons store energy for muscle contractions.

How do ligaments contribute to joint stability?

• Ligaments serve as the primary source of joint cartilage.

• Ligaments are responsible for muscle contraction.

• Ligaments produce synovial fluid for lubrication.

• Ligaments contribute to joint stability by connecting bones, limiting excessive movement, and maintaining proper alignment.

What type of cartilage is found in the knee joint?

• Fibrocartilage

• Bone cartilage

• Elastic cartilage

• Hyaline cartilage

Explain the function of articular cartilage.

• To provide nutrients to the bone underneath.

• To connect muscles to bones in the joint.

• To serve as a protective layer against infections.

• The function of articular cartilage is to reduce friction and absorb shock in joints.

What is the difference between a tendon and a ligament?

• Tendons and ligaments both connect muscles to muscles.

• Tendons connect bones to bones; ligaments connect muscles to muscles.

• Tendons connect muscles to bones; ligaments connect bones to bones.

• Tendons connect muscles to ligaments; ligaments connect bones to tendons.

How do muscles attach to bones?

• Muscles connect to bones via ligaments.

• Muscles attach directly to skin.

• Muscles are fused to bones without any connective tissue.

• Muscles attach to bones through tendons.
