Musculoskeletal System

A ________ is a structure that connects muscle to bone.

• muscle

• ligament

• cartilage

• tendon

Answer explanation

A tendon is the correct answer because it is the structure that connects muscle to bone, allowing for movement. Ligaments connect bone to bone, while cartilage provides cushioning between bones.

A ________ is a structure that connects bones to other bones.

• muscle

• ligament

• cartilage

• tendon

Answer explanation

A ligament is a connective tissue that links bones to other bones, providing stability to joints. In contrast, muscles connect to bones via tendons, while cartilage serves as a cushion between bones.

A ________ is a soft tissue that contracts to produce movement.

• muscle

• ligament

• cartilage

• tendon

Answer explanation

A muscle is a type of soft tissue that can contract, allowing for movement in the body. Unlike ligaments, cartilage, and tendons, which have different functions, muscles are specifically responsible for producing movement.

A ________ is where two or more bones meet to allow movement.

• tendon

• ligament

• cartilage

• joint

Answer explanation

A joint is the correct answer because it is the point where two or more bones meet, allowing for movement. Tendons connect muscles to bones, ligaments connect bones to other bones, and cartilage provides cushioning.

The ________ acts as a cushion between bones at a joint.

• cartilage

• muscle

• ligament

• tendon

Answer explanation

Cartilage is a flexible connective tissue that provides cushioning at joints, reducing friction between bones. Unlike muscles, ligaments, and tendons, which serve different functions, cartilage specifically acts as a shock absorber.

A ________ is a rigid organ that supports and protects parts of the body.

• bone

• tendon

• muscle

• cartilage

Answer explanation

A bone is a rigid organ that provides support and protection to the body, unlike tendons, muscles, and cartilage, which have different functions. Therefore, the correct answer is 'bone'.

The ________ muscle is located at the front of the thigh and helps extend the knee.

• Glutes

• Calves

• Hamstrings

• Quadriceps

Answer explanation

The Quadriceps muscle is located at the front of the thigh and is primarily responsible for extending the knee. The other options, such as Glutes, Calves, and Hamstrings, do not perform this function.

The large bone in the upper leg is the ________.

• tibia

• humerus

• radius

• femur

Answer explanation

The large bone in the upper leg is called the femur. It is the longest bone in the human body, connecting the hip to the knee, unlike the tibia, humerus, and radius, which are located in other parts of the body.

The ________ joint in the elbow allows for flexion and extension.

• ball-and-socket

• hinge

• saddle

• pivot

Answer explanation

The hinge joint in the elbow allows for flexion and extension, enabling the arm to bend and straighten. Unlike ball-and-socket joints, which allow for a wider range of motion, hinge joints are specifically designed for this back-and-forth movement.

The ________ joint in the hip allows for a wide range of circular movements.

• ball-and-socket

• saddle

• pivot

• hinge

Answer explanation

The ball-and-socket joint in the hip allows for a wide range of circular movements, enabling actions like rotation and swinging. Other joints, like hinge or pivot, have more limited movement.
