Skeletal and Muscular System Questions

Multiple choice

The slightly movable joint, which is joined by fibres, is

  1. amphiarthrosis

  2. gomphosis

  3. synostosis

  4. synchondrosis

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

A gomphosis is a peg-and-socket joint and is restricted to the fixation of teeth in their alveolar sockets in the mandible and maxillae. The collagen of the periodontium connects dental cement with alveolar bone. The fibrous connection between a tooth and its socket is a periodontal ligament. In modern, more anatomical, joint classification, the gomphosis is simply considered a fibrous joint because the tissue linking the structures is ligamentous.

Multiple choice

What is the sequence of ossicles in the middle ear?

  1. Stapes-malleus-incus

  2. Incus-malleus-stapes

  3. Malleus-incus-stapes

  4. Incus-stapes-malleus
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Malleus is attached to the ear drum and incus is in the middle while stapes is attached to fenestra ovalis.

Multiple choice

Tendons connect

  1. bone to bone

  2. bone to muscle

  3. nerve to bone

  4. skin to muscle

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

Tendons are dense connective tissues that connect muscles to bones, transmitting muscular contraction forces to the skeleton to produce movement. Ligaments connect bone to bone, providing joint stability. Tendons and ligaments have different structures and functions - this distinction is fundamental in musculoskeletal anatomy.

Multiple choice

Directions: Read the statement carefully and answer the question that follows. No movement is possible between bones, in this joint.

Which of the following joint fulfill the condition stated in the above statement?

  1. Pivot joint

  2. Hinge joint

  3. Stifle joint

  4. Ball and socket joint

  5. Fixed Joint
Reveal answer Fill a bubble to check yourself
E Correct answer
Explanation

Correct. Fixed Joint: In this joint, no movement is possible between the two bones. The sutures between the bones of the cranium are an example.

Multiple choice

Which of the following is an immovable joint?

  1. Shoulder and arm

  2. Hip bone and leg

  3. Ankle and foot

  4. Cranium and upper jaw

  5. Skull and backbone
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

It is correct. The cranium and upper jaw is an immovable joint. In this joint, no movement is possible between the two bones.

Multiple choice

Directions: Identify the type of joint after carefully reading the given clues.

  1. This joint provides movement in any direction.
  2. Its example-Shoulder joints and hip joints.

  1. Fixed joints

  2. Ball and socket joints

  3. Hinge joints

  4. Stifle joints

  5. Pivot joints
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

It is correct. Ball and socket joint: One end of a bone is rounded and ball-like, and fits into a cup-like depression of the other bone. This joint provides movement in any direction. Shoulder joints and hip joints are examples. In the shoulder joint, the head of the humerus fits into a socket of the shoulder girdle. In the hip joint, the large ball-like head of the femur fits into the deep socket of the hip girdle.

Multiple choice

Directions: Identify the type of joint after carefully reading the given clues.

  1. One bone rotates over the end of the other bone.
  2. Its example-the skull rotates on the upper end of the back bone, as an example.

  1. Pivot joint

  2. Fixed joint

  3. Stifle joint

  4. Ball and socket joint

  5. Hinge joint
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Yes, in the pivot joint one bone rotates over a pivot-like end of the other bone. Just like the skull rotates on the upper end of the back bone.

Multiple choice

Directions: Identify the type of joint after carefully reading the given clues.

  1. This joint moves in one plane or one direction only.
  2. They usually give sufficient power, because there is less danger of twisting at the joint.
  3. The joints between the bones of the fingers and toes, are an example.

  1. Stifle joint

  2. Ball and socket joint

  3. Hinge joint

  4. Pivot joint

  5. Fixed Joint
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Yes, hinge joint moves like a hinge in one plane only, just like the hinge of a door. The elbow joint between the humerus and the ulna and the joints between the bones of the fingers and toes are examples of this joint.

Multiple choice

Which of the following body parts have cartilage?

  1. Legs and feet

  2. Skin

  3. Nose and ears

  4. Intestines

  5. Skull
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

It is correct. Cartilage is a soft bone tissue that connects joints. It is present in external parts like the ear and nose.

Multiple choice

How many bones a human body has

  1. 400

  2. 200

  3. 120

  4. 206
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

An adult human skeleton typically contains 206 bones. These include the skull, vertebral column, rib cage, and bones of the limbs. This number is standard for healthy adults, though babies are born with around 270 bones that fuse together during growth and development.
