Skeletal and Muscular System Questions

Multiple choice

Which system has bones, cartilage, ligaments, and tendons?

  1. Muscular

  2. Skeletal

  3. Bones

  4. Skeleton
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The skeletal system is composed of bones, cartilage, ligaments, and tendons, which work together to support the body and facilitate movement. While "bones" and "skeleton" are related terms, they refer to specific parts rather than the entire organ system. The muscular system consists of muscles, which are distinct from these skeletal structures.

Multiple choice

Attaches bone to bone at a joint

  1. Tendon

  2. Ligament

  3. Bone

  4. Cartilage

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Ligaments are tough, fibrous connective tissues that link bones together at joints, providing stability and limiting excessive movement. Tendons, on the other hand, connect muscles to bones to facilitate movement. Cartilage acts as a protective cushion between bones at joints but does not bind them together.

Multiple choice

Attaches muscle to bone

  1. Tendon

  2. Ligament

  3. Bone

  4. Cartilage

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Tendons are strong bands of fibrous connective tissue that attach skeletal muscles to bones, transmitting the force of muscle contraction to move the skeleton. Ligaments connect bones to other bones, while cartilage provides a smooth, cushioning surface at joints.

Multiple choice

Bones are a type of what tissue?

  1. Epithelial

  2. Connective

  3. Muscle

  4. Nerve
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Bone, or osseous tissue, is a rigid type of connective tissue that forms the skeleton. It consists of osteocytes embedded in a hard, mineralized extracellular matrix of calcium phosphate and collagen fibers, providing support and protection for the body.

Multiple choice

areolar connective tissue joins:

  1. bones with muscles

  2. fat body with muscles

  3. bones with bones

  4. integuments with muscles
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Areolar connective tissue is a loose connective tissue that serves as a reservoir of water and salts for surrounding tissues. It binds the outer integument (skin) to the underlying muscles, providing flexibility and support.

Multiple choice

tendon is made up :

  1. areolar tissue

  2. adipose tissue

  3. modified yellow elastic fibrous tissue

  4. modified white fribous tissue

Multiple choice

How many bones does a human infant have

  1. 300

  2. 400

  3. 500

  4. 200
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Human infants are born with approximately 300 bones. As they grow, many of these bones fuse together to form the 206 bones found in an adult skeleton.

Multiple choice

The appendix is an example of a

  1. homologous structure

  2. embryology

  3. fossil

  4. vestigial structure
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

A vestigial structure is an anatomical feature that has lost most or all of its original function through evolution. The appendix is a classic example in humans.

Multiple choice

Antlers are modified ___________.

  1. hair

  2. bone

  3. cartilage
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Antlers are true bone structures that grow from the pedicles on the skull. They are shed and regrown annually.

Multiple choice zoology respiratory system of human mechanism of respiration respiratory cycle breathing and exchange of gas

In human beings, rib case and sternum move upwardly and outwardly during.

  1. Exercise

  2. Sudden back injury

  3. Expiration

  4. Inspiration
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

During inspiration, the contraction of the diaphragm and external intercostal muscles increases the thoracic cavity volume. This movement causes the rib cage and sternum to move upward and outward.

Multiple choice biology body movement joints in the human body our skeletal system and the skin joints

Ginglymoid/hinge joint occurs in

  1. Elbow and shoulder

  2. Elbow and knee

  3. Atlas and odontoid process

  4. Knee and ankle
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation
  • Joints are points of contact between bones, or between bones and cartilages.
  • Synovial joints are characterized by the presence of a fluid-filled synovial cavity between the articulating surfaces of the two bones. These joints help in locomotion and many other movements. 
  • A hinge joint (ginglymus) is a joint in which the articular surfaces are molded to each other in such a manner as to permit motion only in one plane.
  • The knee joint and elbow is a hinge joint/ ginglymoid i.e a type of synovial joint. 
  • So, the correct answer is 'Elbow and Knee'.
Multiple choice biology body movement joints in the human body our skeletal system and the skin joints

Largest synovial joint is

  1. Hip joint

  2. Knee joint

  3. Shoulder joint

  4. Ankle joint
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

A synovial joint is a connection between two bones which consists of a cartilage lined cavity filled with fluid. The knee joint is the biggest synovial joint in the human body. At the junction of the knee, the large femur bone of the thigh connects to both the tibia and fibula of the leg, as well as to the patella or knee cap. So, the correct answer is 'Knee joint'.
